New Redmi Note 3 (SD) TMobile USA loses cellular signal - Xiaomi Redmi Note 3 Questions & Answers

I'm on the latest global stable ROM 7.3.2, I'm not sure why it's so unstable. It'll show HSPA+ and 3G and switch between the two but randomly it'll just drop signal altogether.

You could try the Qualcomm bands unlock procedure. It's really complicated though and might not even work. I think if you do it right it works. I have no way to test it yet even though I've successfully done the procedure.

Can you point me in the right direction?

You need root. After you put the phone in dev options usb debugging and installer mode go to command prompt in adb folder and type:
adb shell
Su
Setprop sys.usb.config diag,adb
That sets the drivers on your pc right for QPST
I used qxdm for the nv edits, i had to dig deep for a link. Then check out these threads:

Save yourself the headache of messing this up and see if you can find the copy of twrp that someone made to backup the efs and other odd partitions. Before you try to change anything also go to QPST, start clients menu, software download, backup tab, and backup your phones nv to a qcn file. Don't share the backup file with anyone until you null out the imei and other unique values.
If anyone has the best qcn file with the most bands unlocked that would be convenient. Another tip is don't add any cdma bands or you won't get any signal.

QPST Help

First off, thanks for tolerating this somewhat noobish post, but I've searched through almost the whole internet trying to find answers.
Alright, so here's the dealio.
Sprint Galaxy Note 3. UICC unlocked via idoneapp, then used on domestic T-Mobile through GCF settings. I want to enable more bands as described in the following links: here and here.
I get as far as Step 9 in the second link. Then, I go to select a port, and it's not there. OK, so I uncheck the "diagnostic port only" check box, and select COM12 which is what my phone is on. No big deal, right? So I go to read/backup my NV and I start it; it only gets to 12% and says "Could not Communicate in Diagnostic Mode"
That's it. I've tried different USB ports, different USB cables, other USB modes on the phone, I even have a custom kernel. I really hope it's something obvious that I'm doing wrong instead of something that's a niche error.
Thanks, guys.
I ended up being able to read the LTE bands with DFS and write them with QXDM. The only thing is that there is no LTE/GSM/UMTS mode on the phone, so it's either LTE/CDMA or GSM/UMTS for now until I figure out if I can flash some other ROM to it to let it use the other bands, cause right now it only wants to look at band 25.
So I've been trying to flash the N900T MI7 modem/baseband on my N900P but I can never get it to flash in Odin. I've been able to put the modem and non-hlos in flash able zips and flash those but it never shows up. I've also tried to dd the files directly but that doesn't work either. Ideas?
I am impressed it's not bricked yet.

So basically what happened was I found a couple other tools to do what I wanted. First was DFS tool. This works well, because it can both read and write bands to the nv of the phone. I forget what the second was, but it could both read and write the raw value of any given value in the nvram. I'll have to dig through my stuff again if you want to know what the second program was. The fact of the matter is that I was never able to get it working right. The phone always looked at band 25 LTE no matter what bands I turned on/off of the phone.
another ?

I never did get QPST to connect to my phone. I think I was able to get it to see the phone at some point, but it would never read anything from it or write anything to it. The program always froze up or something when I tried that. If I could remember the second program I used, I'd share it with you all, but for the life of me, I can't think of it.
Edit: Oh hey, the two programs I used are RIGHT IN MY SECOND POST. lol. Yeah, use DFS tool to read the NV and QXDM to write the NV. It'll save you a whole lot of trouble over doing stuff with QPST.

Flash the MI3 (that's emm eye three) modem and then use the app included in the zip file to find the MSL code. Here's a link to the zip file: http://bit.ly/1oZDO9t
I was not aware that you could change the MSL code with DFS tools. At least I have a Verizon Note 3 now, so I have a lot more LTE bands than the Sprint version does (although I don't care all that much; I think I may switch to the Nexus 6 soon). But yeah, try the stuff in the zip file from the link, and you should be able to
Find your MSL code
Unlock your phone internationally
Use hidden menus
Most of all, have fun! I know for sure this can be very very frustrating a lot of the time, but if you don't have fun, then I don't think there's much profit in trying stuff like this. Good luck!

I have downgrad my phone to 4.4.2, and install custom rom Galaxy-Note-fre3-2.26,
and after using adb and logcat i got my code.
Now how can i activate it for internationally ? i have added all LTE band (3,7,20) but still H+

I just did it with my Verizon Note 3 on Windows 10, so I know it's not a Windows 10 issue. Also, QPST seemed to work with my Verizon phone but not my Sprint phone. Weird. Make sure you're running QXDM as administrator. Also, I unlocked all of the LTE bands in this way but I can't seem to get LTE from my GSM sim card, even by going into the service mode and enabling all LTE bands.

Yes; for LTE i found in hiddn menu, that they use Tri Bands (25, 26 & 41), so for others bands will not work.
I don't know how i can disable this and force it to use bands 3, 7 20.

I honestly couldn't tell you, and I'm not sure how much help I'm going to be in general. I've tried it on both of my Note 3 phones but have had no confirmed success. Sprint especially is the one carrier that sticks out like a sore thumb, and by association, so do their phones. I've had plenty of frustration on that front, that's for sure.

Thanks for your help,
Just one question if have any idea for it
can i install Firmware N9005 using PIT file for N90005 in N900P?
Because when i received my phone(from china) , the first time i see that BaseBand version is for n9005 and phone name n900 but in download mode i see n900p
i think chines have a method to do it

Maybe. Really they have a method to do anything I would advise against trying to do that, although I'm not sure what harm it could do if you can still get back into download mode. I've tried flashing different versions' firmware to the N900P with no success.

[HTC 10] Enable LTE bands by Editing NV values with QXDM/DFS tool - Custom kernels?

Hi!
So I bought a HTC 10 from Amazon back in May and, even though the product description said it was the US version which had LTE bands for US carriers (specifically 4-AWS), they sent me a M10h, which is the international/asian version that doesn't support band 4. I can't return the phone though, since I'm from Argentina and with the insane customs ruling here, sending the phone to the US and back would cost me almost as much as just buying selling mine (at a highly reduced pricepoint since it doesn't support LTE in my country) and buying a new one.
After a lot of reading here in XDA, paying 25$ to be S-Off, flashing radios, changing roms and kernels, and a bunch of other stuff, I've come to the conclusion that my only alternative left is to change the 06828 NV value (which determinates what LTE bands are activated) with QXDM/DFS tools/whatever program. I've managed to put the phone in diag mode (for those who don't know how, I'll leave a little tutorial in the end of the thread), but when I write the value and then read it again it's back to its original state. I guess this is some kind of protection Qualcomm/HTC/whoever put in place to avoid users messing around with this stuff.
I read in the HTC One M9 forums that users with CDMA phones could change the 06828 value, while I, using a GSM phone, have been able to change 06829. I tried using a Verizon radio, which turns on and off the diag mode for some reason, and a Sprint radio, which gives me a "diag error response" in QXDM when I try to read/write any NV value.
Maybe a custom kernel can help avoid the write protection for NV values? I don't know a lot about that kind of stuff, so it's the only thing that I believe could change my situation
Phone info:
White HTC 10 M10h model
LeeDroid 10 v2.4.1-stable rom with CleanSlate kernel
S-Off and root
Baseband version [email protected]_51.01_F
---------------------------------------------------------------------------
For those who can't make it to Diag Mode:
1) Install the HTC Diag Drivers in your PC
2) Install a terminal emulator in your phone (in my case I used SManager)
3) Connect the phone to the computer with the USB cable
4) In the terminal emulator use:
Code:
su
and then
Code:
setprop sys.usb.config diag
5) Now touch on the "Use USB for" notification.
6) If everything worked, the phone should block you from choosing any option in the list besides Charging and USB tethering
7) Choose USB tethering
8) Your phone should appear in the Windows Device Manager as HTC Diagnostic Interface, which means the phone is in Diag Mode
9) To return to the default USB mode, repeat step 4, but replacing setprop sys.usb.config diag for
Code:
setprop sys.usb.config mtp
--------------------------------------------------------------------------
Does anyone know any way to make my phone work? Any kernel made from scratch I can try? I'm really desperate.
Thank you all for reading!
Up!
Bump... has anyone figured this out? The M8 and M9 guys have reported flashing a Verizon RUU/Firmware to allow the LTE NV values to stick, but this does not seem to work on the HTC 10. I've tried everything and have gone this far, but I just cant seem to write the NV values. I've tried QPST + QXDM, as well as DFS. I am not sure if it's the actual firmware/radio itself (though I've also tried them ALL), or just the actual Kernel.
I am stopped on the same spot. I used ElementalX-HTC10-1.06 as kernel without success. Were you able to get anything?

[GUIDE] Band unlocking for OP2

After reading through the OPO thread and someone confirming they saw bands unlocked for their OP2, but could not test if they are working as well as reading through the OP3 and similar threads with our processor I finally delved into trying this. Here is the quick guide of how to do it. Sorry if there is any confusion I will try my best to make it concise as possible. This is my first time writing a guide up for XDA.
I have not been able to test each band to confirm it's working, but it is showing up in Network Guru. I am on AT&T so I only unlocked AT&T bands (bc that's all I care about currently and it makes it easier for me to test)
I WILL NOT BE HELD RESPONSIBLE IF SOMETHING WRONG HAPPENS TO YOUR DEVICE BY FOLLOWING THIS GUIDE!
Credit: All my fellow XDA'rs who have been diligently testing, experimenting, bricking/unbricking, creating ROMs, FLASH, Root ability, and Bootloader unlocking. You are the heart and soul of XDA!

Here is the OP3 thread I based this guide off of and credit to all those mentioned in there as getting this far would have been impossible without them: https://forum.xda-developers.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563
OKAY:
PreReq's:
1. Rooted
2. TWRP or like
3. RMT Storage patch from OP3 forums: SEE POST BELOW!
4. DFS Explorer - Find via searching XDA, again checking OP3 thread or OPO
5. ADB installed (whether that be minimal ADB or like from other toolboxes out there)
6. QPST - Check forums for download
Guide:
1. Put phone in MTP mode if not default (Some default to charge mode) Just go to status bar and press the charging mode to change to file transfer
2. Place file from PRE-REQ #3 in a folder you'll remember
3. Reboot phone (or shut down) and when coming on hold Vol Down+Power for a few seconds and let go
4. Boot into TWRP
5. Backup (If you don't have a backup of EVERYTHING at this point, probably a good idea to do so)
---If you do take only EFS
And install file from #3
6. Restart into System
7. Open up your CMD and run this ADB command :
adb devices
adb shell
su (you will get pop up on your phone to give root authorization for ADB, authorize it)
setprop sys.usb.config diag,adb (this will open your OP3 diagnostic port)
Click to expand...
Click to collapse
This forces it into DIAG mode, check your Device Manager to see if you see a port connection displaying a COM PORT.. IF NOT, you need to install drivers--Search thread for drivers, likely will be find in original OPO or OP3 thread.
***********THIS SECTION IS PURELY PRECAUTIONARY*********************** SKIP TO 11 IF YOU WANT
Purely precautionary we did not have to restore any QCN as they do in OP3 due to encryption:
8. Install QPST, open QPST
Now fire up QPST and go to "Port" tab, and choose "Add New Port" ,
9. On "Serial/USB Port" tab, unchecked the option of "Show Serial & USB...bl bla bla" option, you will see your phone listed there as a "COM#" (# is a number depending on your PC) choose it, and click "OK"
10. Now choose "Start Clients" from the Menu tab above, and choose "Software Download"
**********************************************************************************
11. CLOSE QPST. Open up DFS Explorer, when the signup option comes up it is up to you whether or not you want to register for an account (Good to support them since it's a good application) If not, press the X and the app will be there
12. You should see your PORT listed as you did on QPST. Double click on it (If you can't; confirm QPST is closed otherwise you won't be able to connect to the port) You should see it turn green and highlighted ONLINE if you successfully connected
13. Go to the "Band" option then click on "LTE"
14. Press READ; Give it a second and you should see all currently enabled bands listed; If you want to compare you can go to "Network Guru" and press the 3 dots on the top right and press Band Locking and then press LTE.. Should list the same ones
15. Check the additional bands (Just because it says it's enabled, doesn't mean hardware wise it will work due to chipset hardware limitations; This is why as you all do this if you can confirm which bands for you connected and/or didn't connect we can keep a running list.)
16. Press "Write"
17. Since we're in Demo mode it will count down and then in the LOG box you'll see operation successful
18. Restart the phone at this point and disconnect the cable
19. Wait until it boots up again and go to "Network Guru" press the 3 dots again and go to Band Locking and you should see the new bands listed
*If you don't press the 3 dots and press Clear forcings and it'll prompt that a power cycle may occur; That's okay, let it, mine did, wait until the phone comes back up and repeat 19 and the new bands should be listed.
20. LET US KNOW ON THIS THREAD what bands are working, what aren't. It will allow us to further play with the device to discover if there's limitations or if further editing is required like in the OP3.
*Please press THANK YOU if this guide was helpful.
**Sorry for the missing of some info in the guide! Seems when I added the HYPERLINK it removed most of the other text before it so it started at #4 instead of the remainder of #1-3

usb debugging should be enabled i think, you didn't mentioned that. " (this will open your OP3 diagnostic port)" and here should be op2 i think. thanks for thread, i have a2005 and want to unlock 20 band(800mhz), will try asap, now i have exams running out of time. btw, so the risk of breaking phone is low right, this steps only modify EFS partition only? so hybrid recovery and flashfire can backup/restore if enything goes wrong
What is the benefit from this? Better reception?

Still something is missing
Hi, I think something is missing. Let me describe what I have done on a A2005:
1- I downloaded the rmt_storage from the link provided on Pre-reqs #3.
2- I backed up EFS, installed the patched rmt_storage, reboot into system.
3- I installed the modified HTC modem driver as unsigned driver, did the adb diag port commands, and the phone is recognized by DFS.
4- On DFS, I must click on SPC 000000 since the log shows errors. I'm not sure if a specific SPC value is required ***
5- When I click on Read, it captures the values, I wanted to add Band 3 (1800) so I checked it and then clicked on write. The logs showed that the write was successful.
6- I restart the phone, connect it and load adb diag port commands again, load DFS, click on read and the values stay
7- When I open Network Guru on locked LTE bands, the list shows me the previous one, as if nothing has been written. I restarted the phone already several times, still no LTE on Band 3.
Besides the SPC code, I might think that:
- The rmt_storage somehow it's not working
- DFS keeps the values but they are not reflected into Network Guru or phone. I already set 4G/3G/2G enabled on the connectivity options. No changes
- Maybe there is another value that needs to be changed with another tool such as QXDM
Any help would be very appreciated!!!

In Network Signal Guru, choose clear forcing. And check the LTE bands again,
or, install Network Signal Guru after you done unlocking, else it will show what it remember on previous set up

the guide forget to mention that u need to flash rmt storage patch before do any modification,
else no mod will be saved (will revert upon boot)
the patch is in my OP3 thread
Thanks! So today's update:
1- I connected the phone again, ran adb commands, reviewed the bands again on DFS tool and settings stayed. I'm pursuing to enable Band 3
2- I uninstalled Network Signal Guru
3- On Recovery, flashed again the patched rmt_storage, boot the phone, wrote the values again on DFS tool. Reboot phone
4- I installed Network Signal Guru and now it's showing up on the bands lists. I unchecked the bands default on A2005 and used the ones from Eruper/Asia Model as FDD-LTE: Bands 1/3/5/7/8/20 and TDD-LTE: Bands 38/40/41. My provider in Costa Rica (Movistar) uses Band 3 (1800) for their LTE. I clicked on Band locking, clicked on GSM and WDCMA and removed all checks. Then clicked on LTE and left all LTE bands in hopes that it will connect to that frequency. The list shows:
B1: 2100
B3: 1800+
B5: 850
B7: 2600
B8: 900 GSM
B20: 800 DD
B38: TDD2600
B40: TDD 2300
B41: TDD 2500
When I only picked LTE bands as checked, it never resovled to get connected to any cell base.
5- I dialed *#*#4636#*#* to access the information about the phone and monitored the signal setting it up to "LTE Only". No signal on that either
Top of my head, I will restore the qcn backup I made and restore the backup I made for EFS and start again. Now it's saving values after reboot, which is great, but not identifying anything.
Is there any log worth posting here? I read on the OP3 guide that they were restoring a qcn file with bands enabled. Is it worth trying the same?
Anyone that has LTE band 3 enabled would be very appreciated if they post their qcn backup

I have not been able to further test as all the phones I compare to that are also AT&T ie: AT&T S6 are connected to the same Bands as me so cannot test til I get to an area where other bands are available currently. Will report back as I can test, but was hoping others can test in the mean time as well.

You shouldn't need to restore any QCN or EFS, just re-check the bands you unchecked and it should pickup all the bands again. Also, confirm your APN is correct to be used with LTE?
Did you get ANY LTE Bands before this mod? Or you only have LTE on Band3?
You can use RAT locking to enable LTE Only rather than unchecking all the WCDMA and GSM bands. that way it'll force LTE, if it doesn't go to the Cellular Network tab and press the Preferred NETWORK to go to LTE ONLY.
sadly for me nothing happened, i have a2005 and want to add band 3 and band 20, did everything 2-3 times whats in a guide, everything went well, write process was comlete but bands didn't added
When you say didn't add, you don't see them in network guru or you see then, but unable to catch signal on them?

You tried to force clear in network guru? If so, when you reconnect and enter diag mode and go to DFS, press bands and LTE, press read, did the changes you made stick?
Just so ppl around here know... there is old forum about band OPT band unlocking with various trials of changing bands, which failed, due to missing RMT patch OR BUT it got MANY juicy info !!!
in the past other users sent me qcn/qcnx files of the EU and CN models ( credit: whoever sent me these files from the old thread ) - I hope this help you out.
keep up the good work ! :good:

Have you tried what we said here? And tried to see if you can band lock on 3?
I'm going to see the qcn based off of the op3 guide as well as they had to do qcn restoring.

not yet...it will take me some time, i'm a master's student in exam period.
nontheless, as you can see from the old forum, i'm really interested in opening LTE band 3 on my A2005.
Thanks guys! I live in Venezuela and we use band 3 for LTE and I have the EU version. I'll try this guide today
EDIT: I tried without success, I did all the process but i do not have LTE signal on Band 3. On Network Guru, Band 3 appears as supported. I tried RAT locking but It keeps without signal.

Thank you for the qcn files. I've tried it, and it overwrites my imei, which is expected. Then I tried to replace the imei with mine by hex editor, but flashing the modified qcn still overwrites my imei. We may get into the same trouble with op3, which is the imei encryption.

[GUIDE] Restore baseband - K6 Note - when no IMEI/no outgoing calls/WiFi or BT issues

Hi all,
I just wanted to share what I did when I had a few problems with my Lenovo K6 Note - karatep.
What did I do which ruined my phone?
I unlocked my bootloader, still on stock ROM, haven't installed TWRP yet.
Since then no calls on non-VoLTE network like Vodafone/Airtel/BSNL.
Primary SIM doesn't connect to any other network than 4G.
I had installed CM15.1 ROM with TWRP and Magisk root and I had the same network issues.
When should you follow this guide?
You have problems with network connectivity where you can't make calls on 3G or 2G network.
Primary (data) slot doesn't connect to 3G or 2G.
No signal on either one slot or both the slots.
IMEI shown as null or 0.
WiFi and Bluetooth address either different or shown as unavailable.
Rebooting to fastboot and performing "fastboot erase modemst1; fastboot erase modemst2" didn't work for you and lost your IMEI and/or WiFi and Bluetooth address.
Do not reboot to fastboot and execute "fastboot erase modemst1; fastboot erase modemst2". I lost my IMEI and MAC because of this.
Requirements:
1. Your phone needs to have root access.
2. Your original IMEI numbers and WiFi address, you can find them from your phone's packaging box.
If you don't have your IMEI, better use an IMEI from an old/dead phone of yours. Don't google this up, there can be blacklisted IMEIs.
Steps:
Preparing the .QCN file for restoration
Download and install UltraEdit (you can google up this for the link)
Download and install Qualcomm QPST/QFIL downloader (google it again)
Download IMEI Converter (find it in the attachments below)
Download .QCN file (find it in attachments, this is for Lenovo K6 Note - karatep)
Get your IMEI (for both the slots), WiFi and Bluetooth addresses
Open IMEI Converter and type your IMEI. You will get the hexcode for your IMEI, get the hexcode for both of your IMEIs. Copy the hexcodes.
Open the .QCN file with UltraEdit and search for "08 8A 11 11 11 11 11 11 11" (without the quotes). This is the dummy IMEI in the file, you have to replace it with your phone's IMEI.
In UltraEdit, goto find and replace, search for 08 8A 11 11 11 11 11 11 11 and replace it with your IMEI's hexcode. You have to replace the first hexcode with the hexcode for your second slot's IMEI and the second hexcode with the hexcode for your first slot's IMEI.
Search for AA AA AA AA AA AA and replace it with your WiFi MAC address, this has to update your Bluetooth address as well, there are four places where you have to replace it with your WiFi MAC address.
Save the .QCN file and close UltraEdit.
Enabling DIAG COM port on your phone to download .QCN to your phone
Execute in command prompt.
adb shell
su
setprop sys.usb.config diag,adb
Click to expand...
Click to collapse
This will enable the diagnostic port on your phone.
Restoring .QCN to your phone
Open QFIL as administrator.
Connect your phone to your computer, keep your phone powered on with DIAG port enabled.
Goto Tools -> QCN Backup Restore
Browse your edited .QCN file
Don't change SPC code - leave it as such.
Select Enable Multi-SIM.
Click on Restore QCN.
This will take some time, once done, restart your phone.
Voila! Your IMEI, WiFi and Bluetooth addresses should be updated and network should be able to receive signal and place calls.
Please feel free to reach me if you run into any issues, I'll try my best to help you!
Thanks,
tfr!

Hello,
Sorry for the late reply, we have a bad network connection here due to the lockdown.
Coming to your problem, karatep simply refers to K6 Note, so you have done the right procedure hopefully.
Can you see the IMEI when you enter *#06# in the Dialer?
You're on stock ROM right? Where did you get it from? You did a full flash with QFIL or a ROM flash only? Please note that ROM flashes can be dirty.
If you can see your IMEI, please try the following in the order I've mentioned below.
1. Check the network settings and select the proper network type. Especially if you are on Jio, set it to LTE only, make sure that the non-Jio SIM is set to GSM only. This is the most common problem.
2. Perform a full system reset from recovery, must solve the problem usually.
3. Try lineage 15.1 or 16.0, you'll be able to find the links here, they are really stable and worth upgrading.
4. Full factory flash with QFIL, you should be able to find videos on YouTube, else let me know, I'll be happy to help!
Let me know the results.
Happy to help!

Thank you for the reply,
i do see my imei when i enter the code, Its the sn number that has been changed..
and about the stock rom part, I didn't do it by myself, i had given the phone to a repair shop earlier to fix the issue, this was before i flashed the QCN myself,
i flashed the qcn from a youtube video and all that guy had told was to have stock rom marshmallow, the repair shop had flashed a marshmallow rom so i figured it would do.. but i dont know what tool they used to flash it..
i used QFIL to flash the QCN though..
Let me try the factory reset solution and if that dont work i ll try to flash stock rom again...
for the other two,
1. The network settings are inaccessible for me(i tried to attach screenshots but its asking for URLs)
3. I really dont want to use lineage OS if i dont have to..
let me try the other solutions and i ll let you know..
thank you so much for helping me..

Hello,
You cannot do anything about the serial number, there is currently no way to restore it, it should not limit the functionality of the device.
Is your phone rooted now? Do you have TWRP installed? Try resetting the phone from TWRP. If it doesn't work, restore stock rom with QFIL. Restoring with QFIL will reprogram your eMMC chip and revert it to stock, TWRP will be removed. This will give you the cleanest possible install.
For flashing QCN, you don't need stock Marshmallow. I'm on Lineage 16.0 and I keep changing my MAC address with QFIL, that is not a problem at all.
I'd like to see the screenshots, you can add them as attachments... Use the paper clip icon above, else upload the image to Google Drive and put the URL here.
Happy to help!

Should i try rooting it before flashing stock? I dont want to risk another brick cause of rooting

You don't have to root if you're flashing with QFIL.
How did you flash the QCN without root anyways?
Again, what network are you in?

i followed this youtube video..
https://www.youtube.com/watch?v=1-4tmWvTGiI
i remember reading about it somewhere.. you only need to enable diagnostic mode to flash QCN, and many phones require root to enable this port, and some other need root to unlock to bootloader..
but k53a48 phones have unlocked bootloader and diagnostic mode port can be enabled easily like the guy in the youtube video..
(power off and press power button and volume up till a screen comes on and then connecting the USB, the PC installs the diagnostic port..
this is what i think happened.. i had zero errors during qcn flashing and i hope i didn't do it wrong?
I Have idea network if that is what you asked
The ROM download is complete..so i ll start flashing then?

It's correct that you have to enable only the diagnostic port to download QCN, but I'm not sure of the procedure that you describe here....
K6 Note doesn't come with an unlocked bootloader by default, you'll have to manually unlock.
I'm not sure of the technique that is shown in the video, the general procedure to open the diagnostic port is through adb. But if you are sure that the IMEI is flashed correctly, then there's nothing to worry about I guess.
Again, you're going to flash the S223 ROM using QFIL right?
Your network is fine, it's non-VoLTE, so calls should work if you have restored the QCN properly.
I m downloading the rom from a link in the description of a video..there were multiple stock files and i asked the youtuber and he told me download this one..
Lenovo_K6_Note_K53A48_K53_USR_S306_1709051329_Q00440_POLK_QPST
This is the one that i downloaded.. why are there so many stock files anyway? Is this right? Else
Would flashing stock using lenovo moto assistant application work?
Some people in xda had success using lenovo moto assistant..but the application asks for HW code and I cannot find my HW code from my sn number- HNB1GDX3 ,
No calls are not working, even ussd codes arent working..does that mean that even the qcn flash was done wrong ?:crying:

Hello,
The file seems to be correct. You should install QPST and use it to flash the ROM file.
Lenovo moto assistant might work, I had no success with that though.
The QCN that you used might be probably dirty, I'd suggest you to reflash with QPST and try burning the QCN again. Generate a new QCN before you do.
Sir, I Did custom ROM flash for lenovo K6 note, with twrp and lineage OS 16, after completion of ROM flash, although I have IMEI number, wifi MAC address in about phone section
My problems to FIX:
------------------------
1) Need Volte support(VOLTE not supporting for my JIO SIM)
2) *#06# IMEI code not working(IT shows "Connection problem or invalid MMI code." although the IMEI numbers are available in About phone category under settings)
3) In settings Bluetooth address "Unavailable"

Hey FayazD,
What you've mentioned seems to be a common problem and I couldn't really find a fix.
1). VoLTE doesn't seem to work. Before writing this post (restoring the baseband), no other calls except VoLTE ones worked for me. After restoring the baseband, 3G/2G calls work and VoLTE doesn't work. I'm not sure if there is a fix for that.
2). This could probably be an issue with the ROM itself. Try to flash a different ROM, I recommend AEX, which I'm currently using and is very stable.
3). The Bluetooth address issue again is something which I observed in Lineage 16. It shouldn't affect the functionality, except for the changing Bluetooth address on every reboot. Not sure if it is an issue with the ROM itself, try AEX, this issue isn't present there. Again note that the Bluetooth address could be shown as "Unavailable" when Bluetooth is turned off.
Will update if there is a solution for the VoLTE thingy.

In AEX the VOLTE will work or not, if you give me the assurance i'll flash with AEX

requirements:
adb for PC
QPST
latest EFS Tools from JohnBel: https://github.com/JohnBel/EfsTools/releases/tag/v.0.14

mbn file for your carrier- I used Google Pixel 4a from @swangjang : https://github.com/swangjang/Pixel-...pss/readonly/vendor/mbn/mcfg_sw/generic/Pixel
​1. settings props:​adb shell​su​setprop persist.vendor.dbg.ims_volte_enable 1​setprop persist.vendor.dbg.volte_avail_ovr 1​setprop persist.vendor.dbg.vt_avail_ovr 1​setprop persist.vendor.dbg.wfc_avail_ovr 1​
2. go into diag mode for X55 modem:​adb shell​su​setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb​​Make sure to install the drivers for it manually, especially the Diag Drivers.
3. find the correct com port​go to QPST configuration and find the X55 Modem com port in active phones. After it stop the QPST server.
4. EfsTools​Go to the EFSTools folder and find the EfsTools.dll config file. Open and change from autoport:
efstool port="yourcomport" (e.g. efstool port="com8")​
5. Flash the mbn file​Now its' the same procedure like in the guide from Homersp. So I copy it from there:
You can test the connection by running this in the cmd window:
Code:
EfsTools.exe efsInfo
This should report back some info if everything is working. If not, try rebooting the device and redo the bits from the DIAG guide.
Step 3 - disabling mcfg
Extract efs.zip from above to the same directory as EfsTools.exe, and make sure the mcfg_autoselect_by_uim file is there. Now simply run this in the cmd window, one line at a time:
Code:
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim
EfsTools.exe writeFile -i mcfg_autoselect_by_uim -o /nv/item_files/mcfg/mcfg_autoselect_by_uim -s 1
If everything worked you should see no error messages.
Step 4 - writing mbn
If you are using the Xiaomi Mi 9T mbns zip from above, move it to the EfsTools directory and extract it. Now we simply need to find the mbn for your carrier.
The mbn directory structure is generally laid out like this: <region>/<carrier>/commerci/<country>/mcfg_sw.mbn. For example, the one for my carrier is eu/h3g/commerci/se/mcfg_sw.mbn. Copy the mcfg_sw.mbn file to the same directory as the EfsTools.exe, then go to the cmd window you opened and type this:
Code:
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -v
To get it working on the second SIM slot you will also have to run this:
Code:
EfsTools.exe uploadDirectory -i mcfg_sw.mbn -o / -s 1
If it has worked you should see a bunch of output, but no errors. Try rebooting now, and hopefully after it has booted you will have fully functional VoLTE and VoWiFi.
Thank you! Going to try this for T-Mobile.
Trying this but I can never get my wife's phone to show up in QPST and notice connecting her phone vs my G8 behaves differently in Device Manager. My G8 I'm able to see my Com Port number via Device Manager. The Zenfore only shows up as ASUS Android Composite ADB Interface and under Portable Devices. Weird.

That's strange. What happens in the "normal" diag mode: setprop sys.usb.config rndis,diag,adb ?
Which firmware your wife's has?

Sorry long day at work. It's WW_30.40.30.93.
Doing adb shell, su then setprop sys.usb.config diag,diag_mdm,qdss,qdss_mdm,serial_cdev,dpl,rmnet,adb
It doesn't error or report anything.

Do you have a link for the qualcomm drivers to download? I'm trying to get this to work on T-mobile in the U.S.

I'm not sure, too long ago. But I believe I used the driver of https://qpsttool.com/qpst-tool-v2-7-496 .
The is an extra folder for driver install.

It should work :/
What happens when you use the setprop sys.usb.config rndis,diag,adb ?
Do you got a question from magsik first time after adb shell -> SU?
edit: Tipp: update to 30.40.30.96- it's the official ww Update, the 30.40.30.93 was just test for a few phones
My wife is far too busy and has no time for my nerdy ways! Even though she is gonna miss it (shoot I am too) she is gonna return the phone. She gets way too many business calls and it keeps dropping service sporadically due to being on T-Mobile. Thank you and I hope your tutorial is helpful to others!
I Got Volte VoWifi working on Tmobile in the US for the zenfone 7 pro! Read on below for easy instructions that worked for me.
Ok guys I was obsessing over all this, (as someone who doesn't program at all), how to get volte working on tmobile for the zenfone 7 pro on android 11, version (30.40.30.96), that I have in the U.S. And I ended up giving up on it late last night accepting I don't know what I'm doing in my life in general lol. Then randomly, I restarted my phone today for an unrelated reason and then I saw the volte letters at the top of my phone! I was like WTF!
So I THINK it's fully working now. Though I'm open to someone here helping me verify if I'm truly right or wrong about that. In fact I welcome it because I did it kind of on accident in an easier way than this guide or other guides have taught how to do it.
For more potential proof that I fully got it working:
The settings to enable volte, ("4G calling" as it's called in the menu) off and on are now present in the 'Settings>Network & Internet>Mobile Network' page, which seemingly indicates volte as an option to turn on and off has been enabled on the phone. Also Wifi Voice Calling as an option to enable is also there as well if you click the "Advanced" Menu Option on that same page under 4G calling and 5G Network Options.
BUT, when I check Settings>System>About Phone>Status>Sim Status it still doesn't say Volte or LTE under data or voice, it still says 4G which one might think would be an indicator against volte being truly enabled. Though I think it just means that officially my carrier tmobile doesn't have it activated on my sim even though it is activated on my phone? Could someone correct me on if I have this right?
BUT if i dial *#*#4636#*#* in the phone dialer and click phone information to be taken to secret phone information settings it shows LTE under Both data network type and VOICE NETWORK TYPE, which IS an indicator that I got volte working.
I also downloaded two volte status checker apps from the play store and they both said it is connected so I suppose at this point I am sold unless someone here tells me how wrong I am.
Also when I called my voicemail, aka placed a phone call, it said "HD voice" on my phone and it kept 4G data enabled instead of downshifting to 3G or H+ which is another strong indicator I got it working.
Ok So here's how I think I got it working easily for those who may get it to work doing the same method that's the easiest way I have found.
So I wasn't able to do any of the complicated stuff, (to me it's complicated), in any of the guides above because I just couldn't get my phone to connect right with qspt or anything else for whatever reason. Nor could I get a shell on my computer to even recognize the setprop commands. I didn't even get to the later steps because I couldn't complete the first ones.
What I did was manually entered all of these setprop commands below, on the terminal emulator app that I downloaded from the play store. First I typed in su in the app and pressed enter. Don't know if that matters but it said it granted superuser rights to the terminal emulator app, which I suppose could be important. I'm rooted with magisk and twrp don't know if that matters either.
setprop persist.vendor.dbg.ims_volte_enable 1
setprop persist.vendor.dbg.volte_avail_ovr 1
setprop persist.vendor.dbg.vt_avail_ovr 1
setprop persist.vendor.dbg.wfc_avail_ovr 1
Then I guess I reset the phone a couple times maybe turned the data on and off and then today it was all working and said volte at the top of the phone!
It seems like instead of having to use qspt and all that other stuff to enter the commands through a computer that then connect to a phone I just entered them on the phone itself through the terminal emulator app and it worked?
Other than that I'm not sure how else I got it working because when I tried to enter those setprop commands from my computer to the phone I couldn't even get it to work and the computer kept telling me setprop wasn't a recognized command, whereas when I entered those commands into the terminal emulator app on the phone itself, it DID recognize setprop as a valid command, even though when I entered the block of setprop commands through manual typing it didn't say anything once I entered them to verify that they did anything.
But I think the results say that they in fact DID do something.
I know my explanation is long but it seems I got it working a lot simpler than anyone else has just using the terminal emulator app on the phone itself after having it rooted on android 11 so wanted to share in case someone else can get it to work this way as well because man was it a pain in my ass to figure it out lol.
And please if someone is more knowledgeable let me know if I got it wrong or if there was something else I did to make it work that I'm not aware of at the moment or if I haven't FULLY got it enabled or it's only saying I did or something. But there seems to be a lot more evidence it is working that evidence that it isn't. Called my mom and she said my voice was clearer and richer as well so I think I got it.
I'm looking forward to using this phone in the U.S. and seeing if this radically improves my call quality and connection dependability! Cuz this phone's hardware is awesome it's just the software that is whack and incomplete because Asus cheaped out on the licensing this time. They did it for the bluetooth audio quality also. But Viper for android has solved that as well.

For some U.S. carriers may it work so. I have read in ROG 2 or 3 forum about it. Maybe because Asus has build in these carriers but not activated. For other you need whole procedure....
Tip: you can check your setptop status with getprop e.g. getprop persist.vendor.dbg.ims.volte If you get a "1" back it's activatetd.

Hey there, thank you for the response. I'm glad I didn't have to do anything else because I'm woefully underskilled at understanding the rest of the procedures though with enough time could have figured it out of course.
My image attached below shows what I got when I wrote in getprop to the terminal emulator.
When I wrote the command you gave me specifically it didn't return anything, though there are 1s returning for all the other setprop commands previously entered which is the same thing yes?

I figured out how to enable volte on tmobile pretty easily if you still have the phone to try it out on! My guide on how to do it is posted in this thread.

Hey, awesome to see. She got a new Samsung phone and took her number back to Cricket. Howerver, I haven't had a chance to unroot and relock the bootloader so I could verify this for you on the phone. At least see if the settings stick using an on phone terminal like you did.
Also I do have a Mint Sim I'm test driving for a Mi 10 Ultra. I'll see what happens adding that Sim in since it is T-Mobile after all.
----------
Unrelated sort of. Something happened last night that I didn't think was needed and made me question if any of this is needed at all when trying to get these phones to work on Cricket. So the Samsung my wife bought is the S20 Ultra which is 5G, AT&T variant. I was doing a speed test with my Mi10 and then randomly asked my wife to do it on the S20. Her speed never got over 4G speeds. I mentioned that and she said Cricket charges extra for 5G. Interesting! So I wonder if popping your SIM in a 5G phone no matter what triggers their alarm system and they shut it down because they want the "cost" of 5G. I'm going to take my Mi 10 ultra to the Cricket store and since Amazon has like a 30 day window of needing merchandise back after making a return claim I'll take the Zenfone 7 also. Maybe in store asking to upgrade to 5G nets a different result than popping in the SIM which they recommend anyway, but it shouldn't be this hard.

Update!!! It works and it makes me sad that it worked this easily! Only because we are returning it. Before using Termux as su and entering the commands, my Mint Sim did not show Volte and VoWifi was not an option. Changing the settings Volte shows up in the top of the screen next to the connection icons and going into the Sim options you are able to flip VoWifi on and then that worked as well. Also verified in *#*#4636#*#* Great work both of yall!!! This is a legit option. Will verify taking my MI 10 to Cricket in case that helps further.

I'd be interested for sure and glad you verified a super easy solution that at least works for us tmobile users in the USA. As for 5G on zenfone 7 from what I understand it doesn't have the bands to work on tmobile. I believe ATT has one 5G band available.
Yeah Cricket wouldn't touch either phone. So I'm going to switch to Mint for MI 10.
