Wifi not functioning after flashing Lineage Os14 - Android Q&A, Help & Troubleshooting

Hi everybody, excuse me because i'm a newbie.
After many tries, i have been able to flash a new rom on my Galaxy J320FN (if uou are interested on the method and toos that i used :
Install Twrp 3.0.2 (the only one i have been able to download using Odin, all the other newer releases seemd good downloaded but in the reboot were replaced by original Samsung recovery).
After the install of Twrp i followed the procedure, cleaning data, cache and flashing Lineage OS214 and in a second moment the Gapps package.
The phone is much more better than with old Android 5.1 originally installed and everything works fine except the Wifi.
I can see all the ssids near to me but when i try to connect i can see that the devices makes many tries (i see Connecting) and after a while writes (Saved).
The tries continue and while the device says Connecting i see a toast message (Password may be incorrect) but the password is good because with the same password i connect with my notebook.
I have googled and i found someone that had my same simptoms after flashing Lineage Os214, in some cases one of them solved with some tips in developer section, in other cases , changing the Country in the advanced section of the wifi Menu, but noone of these solutions worked for me.
Is there someone that can help me to solve the problem ?
Another question, is Lineage Os14 the newer rom for my Galaxy SMJ320FN ?

Same here!

[Q] Wifi hotspot and usb tethering problem on GB

Hi, I finally decided to post my question after many hours searching trough google and xda.
Two weeks ago like many of you I uptdated my x10 to pre-rooted 2.3.3 stock Rom. At this moment I successfully tested wifi hotspot and usb tethering built in fonctions.
But Recently I tried to use it again but any time I checked the option, Android activate it for a second, an then says me "error" under the option name. Usb tehter can't be reactived at all and wifi hotspot can be checked but always uncheck himslef with the error subtitle.
Anyone facing this issue or know where it can come from ? And maybe the fix of course ^^.
Hope I made my self clear because actually I'm french.

I use Baracle to solve the issue with wifi tethering
https://market.android.com/details?id=net.szym.barnacle&feature=search_result
Yeah this is the solution I used to adopte when was on 2.1. And it was the best until the update.
But as far as what I tested when built-in tether worked it's clearly better. Not just an Ah-hod network but a real hotspot. Basically it's easier for other devices to connect and remember the password without configuring everything especially on windows.
And the usb option was even better, nothing to configure, no password, battery charging during tethering.
Anyway thank for the advice, until I get the solution I'll probably continue to use this app.
When you say "solve the problem with wifi tethering", do you mean you have the same one ?

Please, no one else, am I the only one facing the issue ? Even on an other device maybe ?
Finally I used SEUS to repare and root it like azazu said. Everything is back. Didn't find any other solution

I have the same problem and it never has been working from the start ! but USB tethering has no problem. The only way to fix it is to re-flash ?
Well I guess this is the best until someone more expert than us find a solution. I made a reparation with SEUS (sony ericsson update service) and then restore all back with Titanium Backup. Remember to save your contacts and sms before (cause Titanium doesn't). It only took one hours to get it all back just like before (root, bravia, Xloud, fps uncap...)
Hotspot error UNSOLVED 2012-02-01
Here's what I've done so far. I've suffered from this issue on two different Samsung Galaxy TAB's 7" (1 generation), two different Samsung Galaxy S2, two different HTC Desire HD, one ZTE Blade.
This issue is NOT caused by:
*Manufacture of phone
*Internet Service Provider (ISP)
*Operator
*Bluetooth ON/OFF
*root ON/OFF
*Stock Kernel
*Mod Kernel
*Stock Rom
*Mod Rom
*Stock Modem
*Mod Modem
*Android version: 2.3+ has this issue. (I've experienced a different issue on 4.0+; the Hotspot is up running although no device can connect to it.)
The only solution I've found is:
(From Clockwork Recovery):
Wipe Data(system reset)
Wipe Cache
Wipe Dalvik
Format Cache
Format Data
Format System
-Install a Rom (try a different one from what you are using right now).
Reboot
RESULT:
Hotspot working fine....for a while..
When it stops working; you'll have to do the steps above again. Install a different ROM, now you probably can return to your previously ROM which had this issue first. It will probably work. If it doesn't, switch ROM till you find one that works. Sometimes, total randomly; you will be able to use ROMS which this issue has been present earlier.
Yet, this is NOT a permanent solution. You will, no exceptions, experience this issue, on whatever ROM, modem, kernel, stock, not stock, phone, whatever, whatever you choose.
Here's one scenario which I couldn't figure out:
Galaxy TAB 7" 1st generation.
Android 2.3.4
*HOTSPOT ERROR*
WIPE/FORMAT
RE-Flashed Same Rom
*HOTSPOT WORKING*

RE-Flashed Same Rom
*HOTSPOT WORKING*
5-10 minutes later
*HOTSPOT ERROR*

I've also noticed that USB tethering is affected by this issue aswell.
If you have it working, congratulations! Use it while it lasts, nothing stays forever.

Need original img <3e> recovery for ViewPad7, pls help

Hi there, I'm new here and I need your help.
My ViewPad7 haven't an original <3e> recovery because i get it from another and it run cooked rom.
Now i want to back to the stock rom following here: http://forum.xda-developers.com/showthread.php?t=1601117 but it need an original <3e> recovery.
Could you kindly help me to get it, if you have a backup of original <3e> recovery from your ViewPad7, please send it for me.
Or you can backup your stock recovery follow this guide: http://forum.xda-developers.com/showthread.php?t=1015005 then help me.
Thank you so much. Sorry for my English.
Anyone, please help?
For Vpad7 - do you have the "older" non-ITE or "newer" ITE (multi-touch) screen - original/stock recovery image file or whatever?
If you aren't sure - post your Vpad7's production date, which is on the printed label on the back as that should help ...
I don't know about the 'non-ITE' or ITE screen of my device. Its production date is: 28-4 2011
Please help me!
Thanks Letitride
Based on device's production date, it's "most" likely an ITE device (there is nothing certain or definitive about it ...)
Okay, calvary to the rescue for fellow XDA's.
AS - please check your PM too (you got mail ...)

Restored & working w the "alternative" *.img as referenced in PM then, excellent & enjoy the Vpad7 - only wished it's a bit faster, overclocking or whatever. But, it is what it is and loved the 7" factor, much easier to slip into a pouch, pocket, jacket, etc. to take along.
Is there anybody with original Viewsonic firmware(v3_420) and with working internet thru mobile data?
i got the viewpad7 back to original with stock recovery that i extracted it from stock rom, thanks
Hello, sorry for bumping this thread but it is relevant to what I need.
EDIT: Moving to thread for visibility.
I recently rooted my Viewsonic Viewpad 7 and put on a custom ROM. I noticed that wifi was not working so I tried some fixes, which none of them worked. One of those fixes involved formatting the sd card. After formatting, I realized I made a huge mistake as my backups are now all gone.
So I have the clockwork recovery installed (v5.0.2.6) and I think it is causing problems. I tried using Software Update Tool L3 (SUT L3) in order to restore the firmware back to normal using the .nbo from the Viewsonic site but I think I need the original <3e> recovery. Whenever I try to recover using the tool, it reboots the device into Recovery mode and after a few minutes I get the error:
Error Code: 0xc60e
Error: Download fail,
Error = SE_ERR_SUT_DETECT_DEVICE_FAIL (0xC60E).
I believe this is because it is expecting the original 3e recovery and doesn't recognize the clockwork recovery. I tried to find a copy of the original recovery.img but I can't find it online anywhere. This thread is the closest I've gotten. Please let me know if there is anything I can do to fix this. Or if anyone has a copy of the original 3e recovery, it may help me out.
Thanks!

Are you using the "correct" factory *.nbo file with SUTL3 (which ver.) as it looked like your model is likely an ITE (newer) model ?
Can you boot the device into CWM Recovery mode now? Does it start up with the VS Android boot animation?
I will have to look for my backups as I've them on a backup server somewhere and/or in cloud storage ... will look & see what I have?
Haven't flash/done any factory restoration work on the Vpad7 in over a year+ now but, as I recall, flashing the *.nbo file via the PC with the factory update utility will wipe the device clean and restore it to factory fresh, locked mode so it should NOT matter what recovery you have on the device now.
Please describe in greater details the steps you took in trying to restore ... it's still a joy to go back to the Vpad7 but hard to let go of the new Nexus 7 quad-core "toy" these days for me ...
Thank you for your help.
I am pretty sure it is an ITE model. It's HWVer is 107, and I used this thread to help figure that out.
I downloaded firmware (.nbo) v3_420 and v3_62 from here. (Under Downloads > Drivers)
Here are the steps I took in order to try and restore.
I started off by enabling USB debugging and plugging in the tablet.
I opened up SUTL3 v1.7.9 and selected one of the firmwares (both yield same result). The update option I set to Erase user data. Once I hit next, it says Updating the Phone software, please wait.
The device restarts into recovery mode. The recovery menu title says CWM-based Recovery v5.0.2.6 which is a custom one I changed. I do not know how to get it back to the original as I have lost the backup.
After about a minute or so, I get
Error code: 0x4000
Error: Download fail,
Error = DEVICE_NOT_CONFIGURE (0x4000).
At this point when I retry using SUT L3 without leaving the recovery mode, I will only get the error from the previous post.
I'm not sure what my options are but my goal is to get back to the original ROM or get wifi working again on the current ROM. The current ROM I am using is CleanView Ice v1.3. I tried both the ITE version and non-ITE version and there seems to be no difference.
The only thing I seem to be able to do is Install ZIP from sdcard which lets me switch between custom ROMs but it doesnt fix the wifi problem or let me go back to original.
---
Edit: I tried doing the same thing a few more times with my antivirus disabled and it's still the same.
Also, I'm not sure if this will help at all but I tried to use the Synchronization tool that shows up on the PC when plugging in the device. It gave me the error "Can't access data on handheld! Please check the connection between desktop and handheld and at least enter Contacts once if you just clear your data!" These may be related as I have accessed Contacts and even added one in to test and this error comes up every time.
Maybe some kind of driver problem?

Okay, let's see - yours is ITE (UK-based) and running the same firmware as mine (USA) and v3_62 will work too, mine is on v3_420.
You still have working CWM 5.x on your device and can boot into it (small pin hole on the button to reset, etc.)
Okay, a # of points - the SUTL3 is run from the PC together with the *.nb0 file - running Windows XP or Vista, go the Command Prompt - Vpad7 drivers are already installed, give it a try - does it work as that will restore it to factory state - it should not need the Stock Recovery to flash it (I could be mistaken as it's been a while) Unpack the Zip file so that the utility will read the *.nb0 file directly.
First suggestio, however, is that if you have working CWM - my recommendation would be to flash from custom recovery, EUv1.7-ITE firmware in Zip file format - as linked here in Dropbox account of mine, OP/developer's link is no longer accessible or available. https://dl.dropbox.com/u/64025118/EUViewpad7v1.7b-ITE.zip
Download & transfer to mSD card, reboot into CWM, wipe dalvik cache, cache & system/full reset - then, flash the zip file and it should be done in about 10 minutes, be patient and go thru the Setup - if all goes well, your ITE device is back to life again. This is my preferred ROM and WiFi works well, if necessary - do a Master Reset again from the running Rom if necessary, reboot once & then setup your WiFi again.
Turn-off Antivirus & Firewall on the PC while flashing ... let me know whether you can get into the EU Rom as it will save you the extra work of going stock and rooting, etc. if your original challenge was just trying to get a good WiFi signal.
The previous times that I tried to install the .nbo files with SUT L3, I extracted them from the zip.
Also, I got firmwares on the UK site but I am Canadian. Most likely mine is also USA-based as many of our electronics are. I just could not find the files on the USA site.
I am running Windows 7 so some drivers installed automatically. I did use Setup.exe to install some other drivers but I have noticed no difference between the two times. Running setup.exe doesn't install anything anymore.
--
Here are the steps I took after your post:
I first transferred EUViewpad7v1.7b-ITE.zip to the microSD card and after rebooted into CWM-based Recovery. I wiped Dalvik cache, cache and "data/factory reset". I then flashed the .zip file and restarted the device after it finished loading.
I noticed the new intro logo so it seems switching the new ROM was a success.
I went into wireless and network settings and I turned on Wifi in the Wifi settings. The device scans for networks for about 30 seconds, then stops and displays "Unable to scan networks" and turns off.
I know for sure there are networks in the area and the wifi was working before I swapped to another ROM.
This is where I am currently stuck.
Again, thank you for your help.

Great, that's major progress - first, let's check & verify a few things and do it step-by-step:
Go to Settings - About phone - check that the following is same or similiar (they should be identical or almost)
Android 2.2.2
Baseband PR3.7_125
Kernel version Apps_2.6.32.9
Build number 4027_3_420
Check under Mobile network settings -
Data enabled (it should NOT matter, only if you are using a Sim card for voice and/or data in Canada)
Under WiFi settings -
WiFi - enabled, cycled it OFF and ON again, does it see various open and/or secured networks nearby
If NOT, press the soft "Menu" key on the lower right (in landscape mode) - it should open up & show "Scan" & "Advanced"
Can you do a manual "Scan" - make sure you have a known working WiFi, either secured or open (McDonalds/Starbuck or public library, etc.)
Next - open "Advanced"
Wi-Fi sleep policy (mine is set to "Never when plugged in" - try to temporary set it to "Never" for this purposes
MAC address - the unique ID for your device should be shown
Tap the WiFi network that you wanted to connect to - check its setting/status for Security, Signal strength, Link speed & IP address
If it previously connected but no longer worked, press "Forget" to delete it, and when it attempt to reconnect (if it is a secured one) - re-enter the password to see if you can connect.
For your restoration purposes, you might want to use WEP or WPA instead of WPA2, or even temporary changed your router to an "Open" WiFi so that any devices including the Vpad7 nearby can connect insecurely, assuming that your router is assigning DHCP automatically and giving out its IP address.
If NONE of these steps are working still, go back into WiFi settings and manually delete any and ALL saved stored networks (named) on the device, leaving just "Add Wi-Fi Network" as the only option.
Next, run a TB backup of your Apps if necessary and boot back into CWM, and do a Backup first to your mSD card (and cover it to a PC if necessary, as you can always restore it back instead of going thru flashing & Set-up) and you will have working boot.img (kernel) saved along with system, etc.
Exit and boot back to ADB (Android) Go to Settings - Privacy setting, and hit "Factory data reset" - next go first into CWM again, wipe dalvik cache & cache again, then continue with regular Setup including WiFi - your device should be able to pickup a nearby & strong WiFi signal.
If all these are still not working, you will likely need to get to a PC or laptop, earlier users had reported having issues with Win7 OS running, I would recommend borrowing/using one with Vista or XP-SP3 running, make sure the USB device drivers are automatically installed first and that it recognize the device. Then, reconnect and run SULT3 and flash the factory *.nb0 file - as I also suspect that there might be other hidden USB device drivers on your existing Win7 system that's casuing the *.nb0 installation to fail.
Keep me posted on your progress and any error messages or crashes (FC) encountered.
(Apparently, some of the custom Roms ended up "corrupting" the WiFi settings and codes, leaving residual settings that casued it to stop connecting to WiFi's - if you look & check some of the posting under "Development" (for some of the Rom's) - you will see some discussions about it. The EUv1.7 custom Rom (non-ITE was initially done and ITE later on) is among the better ones with few WiFi issues to speak of, 15+ months later, still relatively bug-free and updated all the Apps and add-ons of my own from Google Market (Play Store) automatically, with working Flash Player patched, and Angry Birds happily running along - the CPU is slow but with App2SD helping, not too bad for a device running Android 2.2.2 (Froyo)
I checked the settings in the About section and they are identical to the ones you posted.
I left Data enabled however I haven't inserted a SIM card throughout this whole process. I have no data plan anyways with the current SIM card I am going to put in.
Under the advanced settings in Wifi, I changed the sleep policy to Never and the MAC address says "Unavailable". So far there is still no result. I will try connecting in an area where I know there are open networks later today as I live in a public house where I have no access to the router's settings.
Also just a note about cycling Wifi ON and OFF, it automatically turns off after the message "Unable to scan for networks" shows up and no networks actually show up in the Wifi Networks section throughout the whole process. It stays empty even though there are networks around.
There are currently no stored wifi networks either so Add Wi-fi Network is the only option. I recieved this device from someone recently and I completely formatted the mSD card to start fresh so losing any sort of data is no problem to me.
---
I used the backup option in CWM to create another backup and after that I backed up the mSD card through USB to keep the working boot.img and other stuff onto the PC.
Under privacy settings I selected Factory Reset and let the device do its thing. I noticed the intro looked like normal however the Android's "theme" is still like the EUv1.7. I went into CWM and did a dalvik cache wipe along with a cache wipe and reset the device.
I tried the wifi again at this point and still no change.
I also tried SUT L3 with the .nbo and I yeild the same errors as before (0x4000 first time when using from Android screen, 0xC60E after the first time when using SUTL3 without leaving recovery mode).
--
I will test open wifi later today and I will edit the result. I'll also take a look at the discussion on wifi not working around the development forum. Thank you.
---
Edit:
I tested it out on some wifi networks without any protection and still none showed up.
I also noticed that if you right-click the Setup.exe icon in the taskbar after plugging in the Viewpad 7 it gives you the option to uninstall everything that the setup installed. I tried uninstalling and running SUT L3 but there was no difference. Also no difference after reinstalling, just so you know.

I re-read some of the posts about flashing & restoring factory ROM, and it mentioned turning OFF USB debugging mode (from within the device's Settings - submenu) before -
If you want are ready to give up on this donated/given to you device, you might want to try this as a last resort - then, run SUTL3 with the *.nb0 file to restore it to factory stock condition - and hopefully, get the WiFi working.
From your last description of the error MSG - MAC address unavailable, the settings are definitely corrupted / damaged. Some of the Vpad7 owners had to RMA back to Viewsonic for repairs, obviously it is beyond the warranty and not worth the expense now with this "aging" Froyo OS.
The solution, as you probably read it by now, was to wipe clean & go back to stock, root it again and then try a different custom ROM ...

KWBR V4.2 custom Rom, still available for download, will work with ITE hardware - http://forum.xda-developers.com/showthread.php?t=1386469
Since your CWM is still working, give it a try by flashing and perhaps it can get your WiFi working.
I ended up fixing the problem.
I downloaded PdaNet (PdaNetA350x64.exe) and installed it. I used it to get some drivers for the Viewpad 7 when plugging it in. After that, I replaced the custom recovery menu with an original recovery menu file. Once the recovery was back to normal, I tried running SUT L3 and using the v3_420 .nbo file. It worked fine that time and my device's software was back to default.
--
Afterward, I rooted it and put on a custom recovery menu again. This time I used EUViewpad7 v1.7b ITE version and it did not break my wifi. My original cell phone broke and this device will serve as a pretty good replacement for a little while.
Thanks again for your help, Letitride.

Need help please

Hello there.
I got a BP-2 from a friend, which runs on Lollipop 5.1 with a baseband .2.0.2.ci-00017-M8935FAAANUZM-1.
The Model Name is unknown and so it the build number. Certain built-in apps in the phone simply does not work and some android features such as accessibility option or date and time option, when clicked just closes down the settings tab. Moreover, the phone also has issues connecting to PC and Wifi.
Before posting my request, i did all available options to upgrade the rom to latest available on forums. I was able to flash original recoveries and TWRP. I could use ADB and Fastflash tools to experiment sideload options. Nothing seemed to have worked for me. In almost all attempts, the progress just stops at "Patching system image unconditionally......" indefinitely.
I have also tried for days to get past the issue but my bad.
I will really really appreciate, if someone can give me an idea here on what possibly could be the problem and how to address it. Once again, I am thankful to the immense help i am getting from respected gurus here.
Thanks

Some questions regarding the device's software

So here they are -
1. First, Is there a way to create a fastboot rom by extracting files from the device? Or you just have to download it?
The reason - As I've always found that stock roms in any phone are the most stable, and it'd be nice if we could create a fastboot rom out of it. Not to forget that we can also save a lot of bandwidth.
2. I recently tried to unlock my device and I was met with an error "wait 72 hours, use your device actively". So what rules I have to follow?
Moreover whenever I try to close my mobile connection whether through notification tab or inside settings, my device restarts.
Are these related? Though if I'm quick enough that I close internet before sim could load and show the H/LTE sign, then it doesn't restarts. But if I turn it later on and decide to shut it off, then it's bound to restart.
Was just tapping on usb tethering and it restarted, don't know if my connection went off as it rebooted very quickly, but it restarted again.
Update : Tried to switch from mobile data to wifi, still restarted. Sometimes if the sim is a little slow to connect to internet and I turn it off, then it doesn't restart either. The data got turned on later and got shut off automatically as in actuality it was off, but the phone didn't restarted then.
3. I'm having some problems with face recognition. First I registered in a dark environment, unlocked it 2/3 times right away. But when I tried later, it didn't worked several times either in dark or well lit environment. Then I installed it in a well lit environment, same thing worked 2/3 times right away, but as soon as I changed the location to dark or back to well lit, it didn't worked again. Just tried it RN, it worked several times except a few times, so what 's going on here? I'm confused.
Update : I think it's a distance issue.
4. This is a general question regarding miui. Where is the data saver (restrict background data) feature in miui? I've tried several times to find it in different mi phones. But was never able to find it. It's been here from kitkat or maybe even older, correct me if I'm wrong. So why not provide it in miui, such a feature rich rom? Is it hidden somewhere?
5. The stock rom my phone has is based on Android 8.1 (8.1.0 OPM1.171019.011) to be exact, for rom version refer to reply. I've tried different versions of gcam, but none of 'em has worked for me. Normal camera app works fine, nothing I've encountered yet.
These are the versions I've tried -
* F1v9.5_6.2.030.apk (Couldn't install as 6.2 is only supported by android pie)
* MGC_6.1.021_XCAMBase_F1_v5a.apk (Installed and worked, details below)
* MGC_6.1.021_Potter_v7.1_san1ty.apk (Installed, didn't open)
* MGC_6.1.021_Potter_v7_san1ty.apk (Installed, didn't open)
On photo, the camera lags like I'm playing a game at 2-3 fps, same for other photo related options. Except for panaroma, photo sphere, lens blur, these I didin't had problem with. Except panaroma pic never showed up in camera app or gallery. In video it doesn't lag, so recording normal video was fine. But when I recorded a slo mo video, it lagged after the recording, inside & out the camera app. Inside gcam the audio was fine but outside it was muffled. By outside I mean gallery app & vlc player.
I may try other versions but each app is so big.

So here they are -
1. First, Is there a way to create a fastboot rom by extracting files from the device? Or you just have to download it?
The reason - As I've always found that stock roms in any phone are the most stable, and it'd be nice if we could create a fastboot rom out of it. Not to forget that we can also save a lot of bandwidth.
2. I recently tried to unlock my device and I was met with an error "wait 72 hours, use your device actively". So what rules I have to follow?
Moreover whenever I try to close my mobile connection whether through notification tab or inside settings, my device restarts.
Are these related? Though if I'm quick enough that I close internet before sim could load and show the H/LTE sign, then it doesn't restarts. But if I turn it later on and decide to shut it off, then it's bound to restart.
Was just tapping on usb tethering and it restarted, don't know if my connection went off as it rebooted very quickly, but it restarted again.
Update : Tried to switch from mobile data to wifi, still restarted. Sometimes if the sim is a little slow to connect to internet and I turn it off, then it doesn't restart either. The data got turned on later and got shut off automatically as in actuality it was off, but the phone didn't restarted then.

sir, you never mention which version you are on ? since Boot is locked so definately MIUI but which one? global/beta/Eu/ Stable/chine etc?
anways..
Answer for 1, - No you have to redownload it, the Fastboot Rom consist of few extra files like persist and recovery and if they are update you must use the latest one. however via twrp you can take system/data/ and other partitions backup if you want...
for 2. after 72hours, goto dev option and try enabling oemunlock, it will give you warning but do it, come out of dev option and go in and do it again, repeat until the UNLOCK setting stays on UNLOCK, (don't know why it is, but this is how it is,,,, ) , later verify your miui account and sim, keep signed in. download unlocker and sign- in and try unlocking the device (make sure all qualcom drivers are installed)
for 2 again, This is very strange, ONE OF ITS KIND error I AM hearing , I honestly thought this bug is ONLY custom rom related! , you see Poco f1, Beryllium uses MODIFIED VENDOR IMAGE ( can be found at) https://mirror.akhilnarang.me/MIUI/beryllium/.
now these modified vendor images by MIUI dumps logs on data/data/netstat (specially if you are USB TETHERING on 3g, ... you will start suddent System UI reboots and some com.android.xyz processes crashing errors and if you toggle Airplone mode 3g/4g or usb tethering from quick setting , device either hung or system ui restarts or device reboots.
now this error is always in all custom roms due to vendor image
solution? DELETE all files from data/data/netstat and reboot (rooted device on custom rom)
for locked device (unrooted) you may have to flash updated version of miui to fix this bug!
Once you unlock device take latest vendor image ( i am using 9.6.27.9-0 , it has better battery life) and flash custom rom...
for 2 again,,,, some users are complaing that miui10.3.6 alters fastboot commands! and twrp no longer works! , make sure you don't flash miui10.3.6,
for no3,, i don't use facial unlock feature, i will study more and will get back to u if relevent.
for 4
Open MIUI Security App.
Tap on Data Usage Tool.
Tap on Restrict Data Usage.
Now find out those data hunger apps and restrict them by tapping on the green tick.
@YasuHamed First of all big thanks for such a descriptive answer.
1. Now, I'm on stock miui rom i.e. MIUI global stable 9.6.14.0(OEJMIFD).
So If i haven't updated my rom in any way what so ever. can I create a fastboot rom out of it? If I can then also, will that fastboot rom have all the system settings I have on my phone right now? Or will they be default?
2. While not exactly as you said but something similar happened. I do remember enabling the option of oem unlock, but it was turned off. It didn't gave any warnings, so I enabled it multiple times maybe 4, then on the 4th time it showed me a warning and after that it was enabled permanently, even after several boots and reboots.
IDK which "unlock setting" do you mean, which has to say unlock? Is it something different than I mentioned here or are you talking about Mi unlock status, cause I already tapped the 'add account and device' option in it.
Yes really strange indeed. I'm just worried that my hardware isn't damaged? Cause I just got the phone 2 days ago and if it's only a software thing then it's fine. As I'm sure installing/flashing rom would fix it! But I can't RN as you know the time period. Why am I worried? I took my phone to a mobile shop to put lamination on it asap as to avoid any scratches. As you may know that they use heat gun, to do it properly around the curves, I'm just getting a little worried that it damaged my phone's hardware, please give me hope.
Some other strange things happened as well. After some reboots, when I went into file manager app, it would open showing previews etc. but as soon as I click on storage/folders, it says "disconnected" and later I get a message "couldn't add error 10000" like after 10-15 seconds, as I vaguely remember. But after some reboots it would work just fine so IDK what's going on.
3. I also think it's about the experience. More I used it, I think infrared illuminator doesn't throw rays too far, so you have to keep your face a little close.
4. Thanks I found it. But I don't think it is very effective, feature wise. And I also think it isn't working that well RN as it keeps showing the data usage as 0, maybe cause of the bugs? Also the features like restricting data etc for individual apps is good but if you have to restrict background data for each &very app, you have to do that individually. Though if i restrict data, can an app still use background data? As they are different menus. Also it doesn't show usb tethering or hotspot data or anything like that in the list.
Check my 5. question.

sir Gurkirat_Singh
1. sir you are on Miui9.6 which is based on oreo.I have personally updated till 10.0.03 and have all the fastboot command working fine.
you may download miui9.6.22 (a bit updated version from what you are currently on) from
http://en.miui.com/thread-3995650-1-1.html ( both Recovery (1.6gb) & Fb rom (2.5gb) as backup.
2. under Developer options , poco f1 has this trick that OEM UNLOCK doesnt stick on UNLOCK and keeps coming to default once after you exit Developer option. on my 5th attempt it finally stick to UNLOCK and i was able to unlock the device from unlocker Tool.
3. I havent removed my poco sticker from back (yet), put 9h class, bought extra skin my self and book cover too so yes I second that. I always protect my devices like part of me , even the retired ones are sleeping in boxes with proper covers and unused accories!,
now, update your rom and try again to toggle 3g/4g usb tethering. 99% chances are its software issue! and i have faced this issue many times and its my 5th month with device so i havent noticed any hardware damage or performance / speed problems yet... so don't worry. YES few kernels affect network connectivity, however I am on Optimus Drunk kernel on Havoc 2.8 and its working like a charm!
-about file manager issue, can you try the same with FX File Explorer? and report back plz
4.if you restrict globally then miui will only allow system apps to use data in background as and when needed. MIUI won't allow facebook/whatsapp and other VOIP callers to work in the background. Once in restricted mode on miui9 on RN5pro, I used to miss call on whatsapp unless i wake the device up and notifications starts appearing that i have many whatsapp miss calls!, this feature went even worse on rn5pro when i was on dual sim, miui use to prefer carier sim over data sim always! so yes miui has strict data usage control.
5. i am unable to find 5th question plz help
few screen shots of my poco f1 on HAVOC2.8 / OD kernel build20190820 / magisk19.3 / gapps nano
@YasuHamed
1. I didn't got the answer to my question, please read my question again.
2. I'm gonna assume you mean 'oem unlock' got enabled and I'd be able to unlock after 72 hours are over.
2. a. I hope so as well, thanks again.
Although sometimes it would run fine and even after turning off mobile data, wifi, usb tethering etc. it won't restart. I thought the oem unlock setting helped but when I tried not an hour ago, it restarted. Same thing with file manager, it's working fine now, I'm sure 3rd party file managers would work fine as well. Only a few times, it showed that 'disconnected' error.
4. I guess I'd just have to hit and trial myself.
5. Check my OP (original post).

sir
1. I never read any such method so far where you can reverse engineer the extracted files in partitions and pack them back as fastboot rom. and to think of it thats almost impossible because stockroms usually comes with digitally signed by vendors ensuring no foul play.
2. once your 72hrs over, just unlock the oem unlock switch from Dev option, verify sim of on your mi account, download the unlock tool, login using same mi account, hit unlock, after success, the device will BOOT on POCO logo and "UNLOCKED" will start appearing (always) and all data partition, internal storage will be wiped! so make sure you take backup!
2a. with me on custom rom it wasn't a sure thing but it used to happend randomly when least expected.
5. on oreo , GCAM version came in sep2016 worked for me and later ones are for pie and kept crashing (please check old version on apkmirror)
@YasuHamed Thanks for all the help.
5. I did found a version that is working fine for now. But the features I was interested in was super res zoom, night mode, slo mo etc. Super rez wasn't that impressive(seemed similar to stock zoom), night mode either, slo mo still doesn't work properly and phone heats up, even when I'm not using too old of a version of gcam. Even the stock cam app took some good shots with zooming.
And if those features will work better with pie version then IDK what to say cause that new version would come with better stock cam having slo mo, night mode and all that shiz if not everything. So I'm kinda thinking is this gcam port really relevant? It drastically changed image quality with my RN3 but I don't see that now.
Edit: Also I wanted to say that my phone was working fine now i.e. no reboots after closing mobile data or wifi or switching. But you know what they say don't celebrate too soon. As soon as I used usb tethering the problem arised again, I wasn't able to it for 2 days as my PC wasn't booting. Same reason why I wasn't able to reply to you earlier.
Not only this, this whole bugged situation has started to irritate me a lot. Just today I was trying to run flash on my android. And even on the supported browser, it just wouldn't show up. I really hope after I unlock this device, all of these bugs would go away after the data gets deleted, or I'm gonna be more disappointed.
@YasuHamed This has really started to piss me off now. It has started again.
While IDK if the camera or flash not working properly are related to this whole bugged system or not. But I guess usb tethering is the trigger to this whole thing. Everything was working fine, it started to record the mobile data usage, didn't turned off when turned off the mobile data and even worked when I used usb tethering, but suddenly it reboots and the whole **** show all over again. I'm really pissed now. Oh btw it started showing 0 data used AGAIN.

please consider upgrading to MIUI10.3.x , download the complete recovery rom and name it as update.zip and put it in download folder and open updater and call the rom from there , and flash it, I suggest CLEAN FLASHING so all the data will be deleted!
plz take backup!
@YasuHamed can you please find me fastboot rom for miui 9.6.14(OEJMIFD), I tried but I couldn't find it. I'd do the full clean flash through edl mode. That would resolve any bugs related software, right?
Come to think of it, why did this all started happening at the first place? As I remember, it all started after a failed attempt to unlock, I mean not fail fail, I just had to wait before I could do so. Do you see any patterns?
Also if you know anything in this regard, did the stock rom (9.6.14) had such problems back in the day?

frankly i never used my poco on miui either on 9 nor on 10 ,
the day I got, I placed unlock request and after 3-4 days, I unlocked my device and put it on HAVOC and since then my experience is based on custom roms but i did flash miui 10 in between just to have a taste of it! and came back to havoc in a day or two, hence i never deeply tested these feature.
however I do know that modified vendore have created usb tethering problems throughout devices
https://mirom.ezbox.idv.tw/en/phone/beryllium/roms-global-stable/
@YasuHamed I don't think mine contains modified rom. As I went ahead and checked all the possibilities like using cn as in china in the codename of a global rom, updates are also working. I even went ahead to check the authenticity of my device. It checks out with some other things on the box as well. So I'm 100% sure, that this has got nothing related to that.
Some other things which I tried in the meantime. I wanted to test if I can run tegra games on this device. So I installed gltools and build prop. Gltools to make the app believe that my device has the gpu it's looking for. Build prop to make app believe I have the device on which this is supposed to run. But I ended up with the same results. So IDK what I did wrong there? In this regard I wanna ask that, is it possible for root checker to show your device is rooted when in fact its not properly rooted.
Why am I asking this? Cause while going through rooting procedure I skipped a few steps like not flashing 'disable force encryption treble' which I did notice after unlocking, during first boot, the device did do some encryption. I skipped that step cause of something mentioned on this link https://twrp.me/xiaomi/xiaomipocophonef1.html regarding dm verity, but as I just checked the same is mentioned regarding rn3 so IDK what to make of this now, but what I did is not 'swipe to allow modifications' and click on 'read only' in twrp recovery and it did rebooted to recovery properly. As mentioned in the link that some system could force to flash stock recovery. Other than that, not factory resetting, data wiping after root, but does it really matter that much?
I can hear you say that dude you're playing with your device too much, of course it's gonna have these problems. To that, I say I didn't do anything like this, prior to unlocking but the problems were still there if not all of them. So what is the root cause of this then? Do I really need to take it service centre to get it checked out or just flashing the rom through edl mode would fix this?
Not just that after I made those changes in build prop(not including gltools) something very weird/interesting happened. If I would restart my device the boot logo shown is poco but the boot splash is mi logo. And when it rebooted after closing the internet, it would only show the mi logo but then I remember that it must've been soft(hot) reboot as it only shows boot splash.
Not only this, after rebooting the style of the rom changed as well. The icon on the home rearranged themselves a bit. So instead of seeing 5 icons in a row, it was all 4 icons on home as well as on app drawer. As you may know Kika keyboard is defaulty present in this rom but after the build prop modifications, whenever I lock my device and wake it up it started showing ads sometimes, maybe the same ad everytime IDK.
Another thing as you know there is an option of reboot to recovery under about phone updates. When I did that that it showed the 'android' logo. I tried it again but it kept showing the loading sign only.
Also how did you find these files? Thanks again m8. You know just for reference if I'd have to find them myself. Also what are those that say (rolled back).

-sir, most of your observations are pertaining to V9.6.14.0.OEJMIFD, where I am not on MIUI hence I will wait for other members to step in and share their views about them.
- you can always use "Disable-Force-Encryption-Treble" from https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389, when flashing rom (clean flash, FORMAT DATA) to disable encryption on kernel level.
- since Twrp official doesnt support OTA so if you call recovery from updater, it wont work! you may have to use Orange Fox (oct/nov2018) version which had OTA support or better flash full rom after downloading desired version from https://mirom.ezbox.idv.tw/en/phone/beryllium/roms-global-stable/
- what are you looking is from different world of android devices, such as TEMP ROOT, IVORY ROOT (sony xperia on android 5.1) days only! when nothing used to be changed but just to gain access of certain partition temporarily, temp root techniques used to apply to extract DRM KEYS. ITs not the case here hence you will have to root your device properly!
- about gpu, i never tried but you can used app such as FK kernel manage or Kernel Auditor to play with your GPU accordingly
- twrp usually ask keep system readonly whenever flashed new room its standard warning to avoid any bootloops since Twrp doesn't know you will be flashing kernel and/or disabling dm varity soon. so it warns you.
- don't worry POCO is FREE from ARB4 $hit so when page said ROLLED BACK, it means those version were recalled back for some buggs and an update released soon after!
@YasuHamed So IDK whether I was clear or not, cause I couldn't understand most of the answers you gave me, maybe they got mixed up, IDK. Anyways I'll try to keep it simple and answer in best way possible and keep it organised so there's confusion.
1. Thing I forgot to mention, after flashing 'disable force encryption treble' file, my root stopped working, I thought it was part of the whole bugged system. In actuality, when I checked the steps while it was flashing, it installed Magisk 16.7, I think. That's why root stopped working. After flashing latest Magisk, it worked fine. So, After flashing "disable" file, Can I flash Magisk over it to get the latest Magisk version? Will it affect the disabled function in any way? Currently I have 3 files, which one do you suggest -
Disable-Force-Encryption-Treble.zip
DisableForceEncryption_Treble_v18.0.zip
Disable_Dm-Verity_ForceEncrypt_08.18.2019.zip
Third one is form the link you provided.
2. DK if TWRP supports OTA, but I was able to boot to TWRP after tapping on reboot to recovery, just saying. By full rom do you mean the stock roms?
3. Did you meant if it checks out in root checker, then it's properly rooted already!?
4. This FK Kernel Manager or Kernel Auditor, you talk about, does it works the same way as Build Prop or GLTools? Cause I'm not an expert in using these tools. I just followed the steps mentioned in this video https://youtu.be/Y1wPIHhM1Yw similarly for the other games I was trying to run by gathering build prop info related to shield tv/tablet/portable but it didn't worked in my favor.
5. So if you chose the option of 'swipe to allow modifications' options instead of 'read only', and your phone boots without any bootloops or anything, as I've done a lot of time on my RN3 without even thinking about it, does that mean that everything's fine? Even when you haven't disabled dm-verity and still are on stock kernel(the one contained in stock roms i think). Does stock kernel changes to custom when you flash a custom rom? Does TWRP makes any changes to stock one if your system boots without any above mentioned problems having stock rom? Any details regarding differences in these two options?
6. When you say an update released soon after? Do you mean same versions were released with bugs fixed or a new/next version was released? In other words, is it ok to try these versions with such bad bugs that they were called back? Were those system breaking bugs fixed in the same version? Also again, I'd really appreciate if you could tell me how'd you find these roms?
7. I'm almost certain that usb tethering is the trigger to these reboots when turning off internet. Cause if I power off the device and turn it on later, then turn on-ff data, it doesn't reboot but sometimes it does. But as soon as I turn usb tethering on, it would reboot and the whole debacle starts again. And the ads kika shows are different along side something related to ram cleaner everytime. So I think it does uses internet. IK you don't use miui, just putting the info out there, if someone thinks of stepping in later.
please view my replies sir

@YasuHamed So IDK whether I was clear or not, cause I couldn't understand most of the answers you gave me, maybe they got mixed up, IDK. Anyways I'll try to keep it simple and answer in best way possible and keep it organised so there's confusion.
1. Thing I forgot to mention, after flashing 'disable force encryption treble' file, my root stopped working, I thought it was part of the whole bugged system. In actuality, when I checked the steps while it was flashing, it installed Magisk 16.7, I think. That's why root stopped working. After flashing latest Magisk, it worked fine. So, After flashing "disable" file, Can I flash Magisk over it to get the latest Magisk version? Will it affect the disabled function in any way? Currently I have 3 files, which one do you suggest -
Disable-Force-Encryption-Treble.zip
DisableForceEncryption_Treble_v18.0.zip
Disable_Dm-Verity_ForceEncrypt_08.18.2019.zip
Third one is form the link you provided.
I flashed "DisableForceEncryption_Treble_v18.0.zip" and it worked/works, but I always flash before magisk., the current version is Magisk19.3 hence I recomend you to use the updated version, 16.7 is obsolete long back. However if 19.3 may give you bootloops then the max you can go back is Magisk18.0 (since after 18.1, Magisk started using different Script language unknown to some recoveries. However if BOTH (your recovery and Magisk are latest, it should work just fine
2. DK if TWRP supports OTA, but I was able to boot to TWRP after tapping on reboot to recovery, just saying. By full rom do you mean the stock roms?
once on RN5p I tried updating OTA via twrp, it never booted to update hence I recomend you to download full recovery rom 1.8gb, of the build you want and flash it via twrp
3. Did you meant if it checks out in root checker, then it's properly rooted already!?
plz try any root checker and see
4. This FK Kernel Manager or Kernel Auditor, you talk about, does it works the same way as Build Prop or GLTools? Cause I'm not an expert in using these tools. I just followed the steps mentioned in this video https://youtu.be/Y1wPIHhM1Yw similarly for the other games I was trying to run by gathering build prop info related to shield tv/tablet/portable but it didn't worked in my favor.
fk kernel manager or kernel Auditor does support editing build prop, apart from many tweaks for GPU and Cores. the video shows a simple edit in order to think your device is some other version of Galaxy to trick samsung app ; however The boy didn't explain why he just didn't install the already downloaded apk file from fortnite website ?
5. So if you chose the option of 'swipe to allow modifications' options instead of 'read only', and your phone boots without any bootloops or anything, as I've done a lot of time on my RN3 without even thinking about it, does that mean that everything's fine? Even when you haven't disabled dm-verity and still are on stock kernel(the one contained in stock roms i think). Does stock kernel changes to custom when you flash a custom rom? Does TWRP makes any changes to stock one if your system boots without any above mentioned problems having stock rom? Any details regarding differences in these two options?
if you are flashing MIUI From twrp, and DON"T wana ROOT then yes you should never allow system modification because then device will never boot in to system due to DM-Verity. However if you are rooting yoru device, try reading Magisk Lines, It always patch fstab and disable Dm-verity, once its disabled /system parition permision wont be verified on boot. So when you boot in to twrp and you know you are going to flash Magisk, you can ALLOW SYSTEM MODIFICATION swip
on Custom Roms it doesn't matter, because twrp never ask such question. "allow system modification" is only limited to StockRoms
6. When you say an update released soon after? Do you mean same versions were released with bugs fixed or a new/next version was released? In other words, is it ok to try these versions with such bad bugs that they were called back? Were those system breaking bugs fixed in the same version? Also again, I'd really appreciate if you could tell me how'd you find these roms?
the next version above ROLLED BACK one is the bug fixed. (now i don't know what exactly were they) . Also MIUI forums for devices always announce updates! you can google
7. I'm almost certain that usb tethering is the trigger to these reboots when turning off internet. Cause if I power off the device and turn it on later, then turn on-ff data, it doesn't reboot but sometimes it does. But as soon as I turn usb tethering on, it would reboot and the whole debacle starts again. And the ads kika shows are different along side something related to ram cleaner everytime. So I think it does uses internet. IK you don't use miui, just putting the info out there, if someone thinks of stepping in later.
well probably this is the bug of this version 9.6.14 hence you should upgrade atleast to 9.6.20 in order to compare

@YasuHamed Again a little bit confused by some answers, but I'll try to keep it simple.
1. Do you mean you flash "d-f-e-t" file before magisk? That's what I was asking, does magisk interfere with the steps, this file does, in anyway? And why didn't u used the 'third file', the one from the link you mentioned, isn't that the better one in some ways?
2. I never said I tried to install an OTA through TWRP. I just said I was able to boot to TWRP through 'reboot to recovery' option under system updates tab.
3. I checked it with one 'root checker' app, do I need to check with others? Can you name some?
4. He didn't used the same apk, cause he wanted to show & tried to explain, what kind of changes we were doing to the system, rather than just blindly following the instructions, like what normally happens in these scenarios. I thought that was given, anyways, I've tried same things before in past. When I had the apk, data/obb files of an app/game, I'd simply just try to install them on miui and they'd just crash, but doing the same thing on a custom rom and it works, no special steps. Similarly did all this work, and ended with crashes, maybe I'll do the same thing on a custom rom and it'll work. On that note, do you know where I can download stable builds of lineage OS, or do I just have to research which one is a a stable version, Or is it okay to download any latest nightly builds, the only thing they post on their official website?
5. If one taps on 'read only' option the first time, and when it boots to twrp again and doesn't asks for it. Can one find that option somewhere else in twrp? I did that and still I'm booting normally, how's that possible then, if you say system won't boot!? And what does that option 'allow system modifications' do exactly? How unlocking & rooting are different, security wise? Cause vendors like Xiaomi allow unlocking officially, which means it doesn't void your warranty, though I don't know what would happen if you walk in with an unlocked device in their service centre, cause I've never done it, But they still warn you about data stealing during unlock process etc. Although if you root your device then it's out of warranty, but it's a much simpler process than unlocking. So what's the difference, is the threat real? Or is it just marketing to keep you locked in the stock experience?
6. Again you didn't tell me how'd you find those roms!?
7. It's just really random, sometimes it doesn't restart even when internet is turned off, sometimes with usb tethering on or sometimes not even connected to the pc. Kika still shows them ads, also after an app is installed/uninstalled etc. Other than those appearance changes, I wasn't also able to dial down the brightness to the very low. Whenever i did it, it restarted, camera stopped working etc. I revert the changes I did in build.prop to make it poco again, it rebooted and the boot splash was fixed, but as soon as the ui showed up, the poco launcher kept crashing. It was good that I had my apps opened in background and miui remembers them even after reboot, otherwise there would've been no way to access build.prop, so I revert it back to any shield tv/portable/tablet settings and it started working normally. Finally I've decided, I'm gonna edl flash the stock rom and report back if these bugs happen again(I hope it's only software), I downloaded 2 roms over this period of time i.e. 9.6.14 & 10.3.7.0, will try and get back to you.
Sorry for the late reply, got a little busy.

1- Yes I flashed DFET before Magisk19.3 - and why i didn't use the third file, i remember in post one user confirmed this particular one working for him (atleast) so i downloaded that one.
2. I never said I tried to install an OTA through TWRP. I just said I was able to boot to TWRP through 'reboot to recovery' option under system updates tab.
2- ideally this is the case with recoveries which doesn't support OTA, OrangeFox based on OLD version of TWRP does support OTA , I NEVER TRIED but worth reading the post. you should find it in the Poco Development section
3. I checked it with one 'root checker' app, do I need to check with others? Can you name some?
3- I use THIS ONE
4. He didn't used the same apk, cause he wanted to show & tried to explain, what kind of changes we were doing to the system, rather than just blindly following the instructions, like what normally happens in these scenarios.

4- To get general IDEA about altering Build.Prop, The video is Good! however you can not assume Samsung Modded Android over MIUI's one! also It seems the boy in the video has Android7 where Miui Poco is atleast on 8.1, there is huge difference!
The only way to find out whether any type of build.prop (EVEN ON CUSTOM ROMS) will WORK or NOT on POCO; is to Try and find out yourself.
5. If one taps on 'read only' option the first time, and when it boots to twrp again and doesn't asks for it. Can one find that option somewhere else in twrp? I did that and still I'm booting normally, how's that possible then, if you say system won't boot!? And what does that option 'allow system modifications' do exactly?

So what's the difference, is the threat real? Or is it just marketing to keep you locked in the stock experience?
5- Once twrp changes the /System as writable, cannot be undone from Twrp itself - since you have magisk16.7 as you mention earlier the dm-varity is turned off and you are booting normally.
-unlocking means, your device can accept fastboot commands to Alter various Partitions developed by Third Party! /recovery /system /vendor /oem etc
-Rooting is Gaining /system access in Android OS to perform Forbiddon and/or Unsafe Commands / Apps etc
- now your question about security , i will simply say! its HIGHLY UNSECURE to unlock your device & Root it!, there is debate about SeLinux Permissions to be Permissive or Enforcing , SELinux in enforcing mode is considered to be little better and secure but Permissive mode means any command can be run even by hacker to gain your /system access ! REFERENCE
- unlocked bootloader is also very unsafe! anyone can just flash any compatable recovery and atleast WIPE your data!
HENCE this is what i say to all my fellow friends and mates in general! if you are CONCERN security privacy , NEVER ROOT your device! or keep two devices, one being as family device! for fotos, emails contacts etc! and play with the other!
- about warranty! every region has different rules! my country's Xiaomi centre doesn't cover any brick devices because here they are alreadly selling many Redmi fones on UNLOCKED mode! directly from china!
6. Again you didn't tell me how'd you find those roms!?
https://c.mi.com/oc/miuidownload/index select poco and see officially available rom
7. It's just really random, sometimes it doesn't restart even when internet is turned off, sometimes with usb tethering on or sometimes not even connected to the pc. Kika still shows them ads, also after an app is installed/uninstalled etc. Other than those appearance changes, I wasn't also able to dial down the brightness to the very low.

EDL ? you mean fastboot rom flashing via miflasher!, thats not edl! to trigger EDL you must have
1. authorized Xiaomi Account
2. back panel of poco to be opened and short test point to put device in EDL

@YasuHamed
1. I tested the third file. It worked without any problems even after flashing magisk. Cause it doesn't mess or flash any magisk files, it also detects what sort of root the phone have.
3. -> 2. I used the same app to check so.
3. You mention some good points there. That's the same reason, things worked out in custom roms and not miui in my earlier experiences. As miui is heavily loaded compared to any custom rom or samsung experinece. I'll try it on other OSs and report back. On the same note, from what I've read that lineage team doesn't release stable builds or at least not anymore. I'm currently downloading pixel experience. Should I go with this one or lineage os? Is it like any other custom OS or heavily loaded like miui? Also what is the difference between PE normal vs plus vs caf? Also I'm gonna try multi rom, as it would be much better for testing.
4. (new) As you said you use havoc os or havoc kernel I think. Which other custom roms have you tried? Is havoc your favourite one? What sort of uses you make with these custom OSs, just normal daily use or something else? Or anything else you wanna share in this manner about your experience, recommendations or anything else.
5. I think I understand a bit, if I use the option 'swipe to allow system modifications' and do not root my device i.e. not flashing magisk which in turn won't disable dm-verity and then if I try to boot to system, it'll go in booloop?
IF I'm right, then what is "read only & root" vs "allow system modifications & root"? Also I have the latest magisk version. What I was trying to say, "When I flashed the 'first' file out of the three 'dfet' files, it flashed magisk 16.7 as well causing latest magisk manager to not work", which I figured out and fixed immediately.
Also when the first time I flashed twrp, only then I got these options. But later on when I flashed the fresh rom through fastboot and then the recovery I simply got booted to the main menu without getting to choose any of these options. During that, I formatted all the stuff like system, internal storage etc. which i wasn't supposed to format, cause of which I had to flash again, but I forgot to select the 'clean all' option instead of 'clean all and lock' option. So i had to unlock again and flash twrp again. But even after all that twrp remebered all the changes I made to it like time, vibration, brightness settings and again it didn't showed any of those two options. More on this in the last response.........
6. And again you gave me the link to miui's official website. I was asking how'd you find all those older roms at one place.
7. So I finally flashed miui rom today, having high hopes, which were proven to be right first then crushed down later. After I flashed the rom, I tested the heck out of it like turning data on/off, usb tethering on/off, no problem occured, didn't found any bugs except one in data usage, it was showing like 100-600gigs(I don't remember exactly) of usage, then it started showing 1300-1400gigs, but after seeing that my confidence dipped down a little.
But still I moved on and flashed twrp on it to get it rooted. After rooting everything was fine even the data usage bug also went away, then I installed gltools and I had my phone connected to pc in usb tethering, suddenly I hear a sound(it restarted<insert gta sa cj meme>) and it starts all over again. I flashed 9.6.14 ver of rom btw.
As you already know from my response above that I was only able to flash through fastboot mode and I wasn't able to get into edl mode as I read just a few hours ago that it's locked away. So my question is, is there a chance that this all could be solved if the rom is flashed through edl. As that's much more of a clean install rather than fastboot, as I mentioned twrp remembered the settings and all that shiz. Or should I just try another ver of miui I have or the custom rom I've downloaded?
Also to get into edl mode, does both of these requirements needed to be met? Or any 1 should work? :-
Authorised account - So who can get this? Is there any bypass or workaround for it?
Test Point - I don't wanna open my phone, as you know it's new & all, tho it's not a problem if there's no other way. It's just that I have some bad memories regarding test point of my beloved RN3(now dead) so I just wanted to stay away from hardware as long as possible. Is there any bypass or a workaround for it?

we i am glad , we have a winner here

Temporarily , LOS is suspended but even unofficial roms till mid August are very stable ! you should try! , hoever Pixel is very popular too, on deeper level what diferences you may find thats only user can discover over time. there is no direct answer to this question! LOS is driven from CynogenMod which was on AOSP wehre Pixel is CAF based, so the difference comes on Kernel Level this means CAF rom may have different Hardware performance / behaviour when compare to AOSP based roms (and vice versa). I am not sure about multirom as a daily driver, yes I would like to try for fun but wont keep it.
4. (new) As you said you use havoc os or havoc kernel I think. Which other custom roms have you tried? Is havoc your favourite one? What sort of uses you make with these custom OSs, just normal daily use or something else? Or anything else you wanna share in this manner about your experience, recommendations or anything else.
on Poco i have tried Nitrogen, Omni, MoKee, BootLeggers, CrDroid, LOS and Havoc..
BootLeggers is pretty stable rom! however CrDroid is outstanding because the developer @gwolfu is more active and releases many updates (sometimes 3-4 in a month). Crdroid has serious level of customization (dirtyUnicorn) and you can change the look of your rom in every possible way you imagine!
so the question is WHY am I on Havoc, well the simple answer is both Crdoid and Havoc Offers serious level of DU customization & variations found on deeper level. some items which crdroid doesn't offer i found in Havoc so I stick to it, moreoever I feel the font and resolution by default in havoc is next to pixel where in Crdoid you manualy have to fix (dpi and font)
now I am on havoc2.8 but I am using Optimus Drunk Kernel (which is also used by CRDROID) - the developer of havoc2.8 offers SHADOW kernel which as I said I feel is not very battery effcient (atleast for me, others can disagree)
5. I think I understand a bit, if I use the option 'swipe to allow system modifications' and do not root my device i.e. not flashing magisk which in turn won't disable dm-verity and then if I try to boot to system, it'll go in booloop?
IF I'm right, then what is "read only & root" vs "allow system modifications & root"? Also I have the latest magisk version. What I was trying to say, "When I flashed the 'first' file out of the three 'dfet' files, it flashed magisk 16.7 as well causing latest magisk manager to not work", which I figured out and fixed immediately.
-keeping system Read only OR swipe to allow /system as writable is on Recovery Level ,
- when you keep system on READY ONLY on recovery Level and later flash magisk, the module magisk modify the /system permission which twrp doesn't know!
-if you "allow system modification on twrp level the /system is now set on writable permission by twrp, and magisk is a module which is always set to alter /system partition permission irespective of Global policy on recovery level
Also when the first time I flashed twrp, only then I got these options. But later on when I flashed the fresh rom through fastboot and then the recovery I simply got booted to the main menu without getting to choose any of these options. During that, I formatted all the stuff like system, internal storage etc. which i wasn't supposed to format, cause of which I had to flash again, but I forgot to select the 'clean all' option instead of 'clean all and lock' option. So i had to unlock again and flash twrp again. But even after all that twrp remebered all the changes I made to it like time, vibration, brightness settings and again it didn't showed any of those two options. More on this in the last response.........
now this let me think a little bit, the only possible explaination (in theory) I found is
- when you flash all or clean flash all, its not necessary that /recovery partition is first erased by miflasher! and recovery.img file has many folders including setting folder! so miflasher and later by you simply there was swaping of recoveries, the Tree was always there! when you reflashed twrp! try to do this way
Code:
fastboot erase recovery
fastboot flash twrp.img
this should erase any previous left over data and settings
try and let me know!
6. And again you gave me the link to miui's official website. I was asking how'd you find all those older roms at one place.
i simply google / web search rom number with device name with code name like Miui9.6.20 fastboot download poco f1 beryllium and google suggest few popular results which usually works for me!
7. So I finally flashed miui rom today, having high hopes, which were proven to be right first then crushed down later. After I flashed the rom, I tested the heck out of it like turning data on/off, usb tethering on/off, no problem occured, didn't found any bugs except one in data usage, it was showing like 100-600gigs(I don't remember exactly) of usage, then it started showing 1300-1400gigs, but after seeing that my confidence dipped down a little.

I flashed 9.6.14 ver of rom btw.
I would say 9.6.14 had bug so reflashing didnt help! as I said before, consider upgrading atleast to 9.6.20
As you already know from my response above that I was only able to flash through fastboot mode and I wasn't able to get into edl mode as I read just a few hours ago that it's locked away. So my question is, is there a chance that this all could be solved if the rom is flashed through edl.

till MiMax
-holding THREE buttons for 30 seconds used to trigger edl mode
-miflasher simply identify EDL mode and used to flash the beryllium fastboot rom
the question is why they stopped?
well fastboot rom when extracted, hackers can simply alter and repack the img files! YOU CAN EVEN place twrp as "recovery.img" in extracted folder miui will flash twrp thinking its vendor recovery! and the device in EDL mode will accept it..
this was serious security risk! so they capped EDL mode in both ends
- miuiflasher needs AUTHORISED ACCOUNT
- DEVICE won't enter in edl mode unless you remove back cover and under batter wire you short two motherboard points with thin wire or tweaser! (and immediately connect usb calbe to system)
now what can you do?
1. use older version of Miflasher which doesnt verify rom
2. user altered rom of specific build or time to WAKE UP your BRICKED device!
I have never done it so you need to investigate and use your poco as gunie pig to test these methods after REMOVING Back Panel (HIGHLY NOT RECOMENDED
or take device to authorised Mi Dealer and let them EDL for you!

H-ROM S20 Port by Astrako breaking SIM & Wi-Fi

Hello, I've recently installed the H-ROM S20 Port by Astrako.
It was working fine until after a few days I realized that Wi-Fi is not working when my friend tried to give me hotspot (It was the first time I was accessing Wi-Fi on Astrako's masterpiece).
I realized this was a big annoyance so I decide to go back to my J6 stock ROM only to find that SAMSUNG doesn't allow for downloading ROMS (The error while flashing the stock ROM was something like: sw rev. check fail (bootloader) device: 9 binary: 7).
I tried several ways of flashing the stock ROM, even tried flashing single components like CSC, BL, AP alone but it always gave me that error and resulted into a soft brick.
I managed to get around the soft brick by booting into TWRP and flashing H-ROM again. But after this episode, the SIM won't work either in addition to the already broken Wi-Fi.
Searchs around the Internet have suggested that it is the `efs` partition that is broken. All tutorials suggested to restore the efs partition but I did not have a backup so nothing to do. Another solution suggested messing with USSD codes like `*#06#` which always made the Phone app to go unresponsive.
So these are the possible solutions:
- Is there a way to allow downgrading of ROMs so that I flash the stock ROM?
- Someone with a J600G can provide me with their EFS backup
- Somehow fix the Wi-Fi/SIM issues otherwise because these issues are definitely not H-ROM's side effects.
