try to update and see if it there

important point. after confirming the desire to unlock and clear data, the bootloader really(!) unlocks only after the initial settings and when you see the gray immutable "OEM unlock" switch in the developer menu.
If you didn't see this item the first time, you need to enable the Internet and update the security policies, and at the same time disable them immediately.
This is the only reason for the appearance of the red inscription "only official ..." and this is the way to switching "rmm state" from prenormal to cheking.

What can I do if this;
Go in Developer options > enable OEM unlocking.
Is not available?

Hey guys, my friend gave me his a21s to unlock it but I really can't find a way to do that.
The phone has a pattern lock that he doesn't remember it...
Also it doesn't have Developer mode enabled.
and in recovery mode, FactoryReset option is not available...
any idea?

I think you are booting your phone into bootloader mode.
You do not have to boot your phone into bootloader mode, instead you have to boot in Odin mode. For that, switch off your SAMSUNG phone. Afterwards, press both volume buttons and insert the data cable into your phone simultaneously. (Note: your device should be of samsung otherwise the Odin application will not recognize your device. Your data cable should be connected to pc to enter Odin mode). Then a blue coloured screen will appear. You have click the volume up button once and you will enter Odin mode.
Thanks!

[Guide] Unlock Bootloader and Root Huawei Ascend XT

IMPORTANT: It appearance that Huawei is no longer going to provide bootloader unlocking services for their devices. Because of this, this guide is of no use unless you can find a way to get a code or you just held onto the code.
Hello, this is a guide for unlocking the bootloader and rooting the Huawei Ascend XT. I am writing this because the current guide is not very well written and does not contain bootloader unlock instructions. This will be split into two parts: Part 1, unlocking the bootloader, and Part 2, rooting the phone.
PLEASE NOTE THAT FOLLOWING THESE INSTRUCTIONS WILL WIPE YOUR DEVICE. I AM NOT RESPONSIBLE FOR AND DAMAGE DONE TO YOUR PHONE!
THINGS YOU WILL NEED:
1. A Huawei Ascend XT with at least 60% of battery left
2. A computer with adb drivers, fastboot drivers, and the Huawei USB drivers
3. A Micro-SD card for your backups (THIS IS VERY IMPORTANT! PLEASE MAKE BACKUPS!)
4. TWRP for this phone. This can be found here: https://forum.xda-developers.com/android/general/huawei-ascend-xt-h1611-t3507933 (credits to enigma2446)
5. The ZIP containing SuperSU. This can be found here: https://forum.xda-developers.com/android/general/huawei-ascend-xt-h1611-t3507933
6. The SDK Platform Tools. These can be found on the android studio website.
PART 1: UNLOCKING THE BOOTLOADER​1. Geting the Bootloader Unlock Code: You need to get your bootloader unlock code. You can get this by going to https://emui.huawei.com/en/plugin.php?id=unlock
(EDIT: It appears that this website is down. I have read that if you PM Huawei on Twitter or call them and provide all the details of your phone, they will give you a code. I have not tested this method, bit people have said it worked with the mate 10.) and signing into your Huawei ID. If you dont have one, create one. Then, follow the instructions given to you by Huawei to get the code.
2. Enabling the Enable OEM Unlock Option: To enable this option, you must enable developer options. To do this, go to Settings>About Phone and tap the Build number until it says "You are now a Developer". back out of About Phone, and go to Developer options. turn on "Enable OEM unlock" and press Enable.
3. Enable USB Debugging: While you are still in Developer options, enable the option 'USB debugging" and press OK.
4. Booting Into the Bootloader: once you have completed the first three steps, you can now boot into the bootloader. Connect your phone to your computer, and open the Platform Tools folder you should have downloaded and extracted. Shift-Right click, and press "Open Command Window Here" or "Open Powershell Window Here", depending on your version of windows. Once it is open, make sure your device is detected by typing "adb devices". If it displays your device, you are good to continue. If not, something is not set up right on your computer or phone. Once you verified that your phone is detected, type "adb reboot bootloader".
5. Unlocking the Bootloader: Once your phone has booted into the bootloader, you can now unlock the bootloader. YOUR PHONE WILL BE WIPED ONCE YOU TYPED THIS COMMAND. You can unlock it by typing "fastboot oem unlock <your bootloader unlock code>". Once it has finished, you can reboot your phone, and just run through the setup fast, because you will still have to wipe it again.
PART 2: ROOTING YOUR PHONE​1. Move the TWRP image you downloaded (called
Xtrecovery) to your Platform Tools folder and rename it to "TWRP.img"
2. Insert Your Micro-SD Card
3. Move the SuperSU Zip you downloaded to the SD card
4. Re-Enable USB Debugging: Enable Developer options by going to Settings>About Phone and taping the Build number until it says "You are now a Developer". Back out of About Phone, and go to Developer options, and enable USB debugging, and press OK.
5. Boot Into the Bootloader: Type "adb reboot bootloader" into your open CMD window or Powershell window.
6. Verify That your Phone says that the Bootloader is unlocked
7. Type "fastboot boot TWRP.img"
8. TWRP should boot. Tap "Keep Read Only"
9. You should now be in TWRP. Go to Backup>Select Storage and choose your Micro-SD card and tap OK. Uncheck everything and check "Recovery". Then, Swipe the slider to back up your stock recovery partition.
10. Once it has finished backing up, reboot your phone to the bootloader.
11. Once it is in the bootloader, type "fastboot flash recovery TWRP.img" to flash TWRP as your recovery. (I believe this is the point where your warrenty will be invalidated by Huawei, so be careful.)
12. When it finishes flashing TWRP, reboot your phone to TWRP by holding down the power button and volume up
13. It should boot to TWRP. Tap "Keep Read Only", then go to (YOU ARE ABOUT TO WIPE IT AGAIN)Wipe>Format Data and type yes, and hit the enter button.
14. Once it finishes, go to Backup>Select Storage, select your SD card and hit OK, then check every box to backup all six partitions, and swipe to back them up. (At the end, it may seem to get stuck at 98-99%, DO NOT STOP IT! It is generating an MD5 checksum)
15. When it finishes backing everything up, go back to the home screen of TWRP, then go to Install, navigate to where you stored the SuperSU ZIP, select it, then swipe to flash it.
16. When it finishes flashing the SuperSU ZIP, tap "Clear Cache/Dalvik" and swipe to clear them.
17. Reboot your phone. IT WILL REBOOT MULTIBLE TIMES AND APPEAR TO BE STUCK SOMETIMES, BUT DONT TOUCH IT! This is normal and it will eventually boot like normal.
That's it!
Your phone should now be rooted and have SuperSU installed. Please note that this is a Systemless root, and will be removed if you factory reset your phone.​Thanks to divineBliss for creating the original instructions.
What do we do after we get root to install custom ROMS? please advise

Click to expand...
Click to collapse
To install a custom ROM, you need the ROM you want to install, gapps depending on the ROM, and the proper firmware. The firmware you are on can be found under about phone and is the last 4 digets of the build number (in the format of B1xx). Once you are on the proper firmware, have your ROM and other things it may require, (every ROM is different), and a backup (just in case), you can flash the ROM from TWRP. Follow the instructions provided by the creator of the ROM to properly flash it.

It will not. The TWRP recovery image is device specific and might brick your device if you flash it to your phone.

Well I did not see that, so yeah, I have bricked it. IT comes up and says it is unlocked, it used to sit there then boot into the system.
So I downloaded the TWRP, tried to reboot to recovery and nothing.
Now, it just gets to the yellow warning screen, then goes black. Just bought this today on a black friday sale for 49.00
But did it for a reason. Now I would like to be able to recover it....
I was able to run adb and fastboot, so know that the drivers work, but it looks like it won't even get there now.
And it won't even go to the recovery, so I guess this phone is a real brick.
Can't seem to get the back cover off to remove the battery either.
You need a copy of the stock H1711 recovery image to use
"fastboot flash recovery H1711-stock-recovery.img" to restore the stock recovery. Until someone creates a working H1711 TWRP, I don't know where you'll find a stock H1711 recovery image file.

Sure it does
Notes on booting up the phone (from power off)
Bootloader (fastboot) = power + volume down + USB hooked to pc
eRecovery = power + volume up + USB hooked to PC
TWRP = power + volume up

Optionally you put phone into bootloader/fastboot or recovery modes by typing from an adb prompt "reboot bootloader" or "reboot recovery"
Hi there. The website link for submitting your imei to get the unlock code doesn't work. Does anyone know how to get this code now?

You'll have to use DC Unlocker and pay to unlock until the page returns
Since unlocking the bootloader is no longer supported, I have a suggestion but am afraid to try myself.
So, download stock version of rom (aka fastboot rom). Extract, replace recovery.img with twrp (renamed to recovery.img). Restart phone in EDL mode, flash. In theory, edl is working fastboot mode so it shouldn't matter if bootloader is unlocked, correct?

Imma try this out, I’m stuck in a weird situation where my sd card slot broke. When I sent it in for service, they said it was rooted and refused to fix it. I specifically did not root it so that I could send it in for warranty service. So it’s mission to try and root, unlock boot loader etc so that I can have more storage space

installing twrp or cwm recovery and rooting Samsung Galaxy A10

So i recently bought my Samsung galaxy A 10 ,I have been trying to root it but no luck.i unlocked the bootloader, installed proper adb drivers and latest version of odin on my Pc. I was following procedures from rootmydevice.com slash root-samsung-galaxy-A10(sorry cant post external links, im new).evrything went fine up until i got to the flashing part using odin. I am not sure weather the twrp file is corrupt or I am missing something.anyone who might know please help.
here is my device info:
SM-A105F
Have you tried this tutorial:
https://forum.xda-developers.com/galaxy-a30/how-to/root-galaxy-a30-magisk-canary-relaese-t3936481
I'm stuck in two problems here...
1- I dont have the option OEM Unlock on my developers option. I think that it maybe because ive checked that option before and after that it desapeared... When entering on download mode, it shows OEM Lock: ON (L), i dont know if that means OEM is unlocked or locked...
2- I cant find the files in step 2: .extract the boot.img.lz4 from the AP file.
Just came here to find a root method for the SM-A105M. Seems like not a lot of love for the A10 here.. Lol Anyways, I will be testing this method I came across out tonight. I will post the link but can't confirm it's working. I'll post my results tomorrow.

Hi everybody,
I managed to root my A105FN with this method but with using the Magisk Manager v7.3.1 (no need of Magisk Canary)
It will be good to have a TWRP as welll but couldnt find a compatible one for the A10 (maybe useful for no-verity-opt-encrypt-6.0 and RMM-State_Bypass_Mesa_v2 patch)
we need :
1. odin 13.3.1
2. official firmware for your device (to get the boot.img from AP_xxxx part => follow the other tutorial how to get boot.img and boot.tar magisk patched)(keep an original boot.tar, just in case stuck at boot)
3. 7zip ZS
4. Last Magisk Manager (for me was v7.3.1)
5. computer + usb cable
Warning : this root will give you big warning messages at every boot !
First you need to unlock your bootloader :
1/Under android, activate internet and go under "Developper Mode" (Setting>About>Software>Build Number and Tap on the build number repeatedly). OEM unlock option should be there.
If not wait and retry to see if there ... (needs internet, dont know why)
2/Then go under Recovery Mode (VolUp + Power at phone boot). No method to go "Download Mode" directly for my device.
3/Under Recovery, we need to unlock the bootloader as well. I cant remember what exactly I pressed but try to press VolUp or VolUP+VolDown just after you click to reboot under bootloader... It should show you a page where you can choose to unlock bootloader by long pressing VolUP. if you dont have it, retry again ... without that no Flash possible.
Warning : this unlock will give you a big warning at every boot !
4/if you managed to unlock the bootloader, it s almost finished... know under Download Mode with bootloader unlock, flash with Odin the magisk patched boot.tar. Do not forget to untick "reboot" under Odin.
(reminder:follow the other tutorial to get the file and remember to use the Magisk Manager v7.3.1 and not the canary.)
5/when flash done, reboot by pressing VolDown+Power then immediately on reboot VolUp to go under Recovery Mode.
6/Under Recovery, erase data/factory reset and reboot to system
(7/I dont know if it s necessary the VolUp at reboot till the vibration)
8/wait the booting ... if you are stuck on the warning page for a long time, retry to reflash the original boot.tar and restart from "1/"
9/if you managed to boot under android, good news you are rooted but it s not finished yet....
Under Android check you have "OEM unlock option" under Developper Mode (cf. 1/) otherwise at the reboot the system will go KO.
So when you have "OEM unlock" enabled you can install Magisk Manager. It will ask you to install something and it will reboot automatically. That s why check you have "OEM unlock" enabled before doing that !
10/After reboot, Done. ROOTED.. enjoy ! you can reboot as you want ...

Everything is about having this flash file you said you used. Please send us the link for that twrp file or whatever it is called right now as it is maybe not a Team Win Rom.

Hi,
It is not a TWRP file, it is the boot.img file from the original firmware for A10, patched with Magisk to access the root function, unfortunately it does not work, have tested it.

First you have to access developer mode. You have to tap several times on the build number. (Settings/about the phone) In developer mode you heve to enable oem unlocking and usb debugging. Wait for permission request on the phone for access of your PC when attached to the phone.
Next step is to unlock the bootloader.
After this you will be able to install TWRP, which finally gets you to the point where you can install a new ROM. Just follow step by step:
Install LineageOS on a5y17lte | LineageOS Wiki
wiki.lineageos.org
Of course, instead of Lineage, you can use any suitable ROM

How far did you get? OEM unlocking and usb debugging successful?
When putting your phone in fastboot mode and attaching it to the pc, check with "adb devices", if your phone is properly recognised. Using windows, it´s often the drivers. On my system, I had to manually select the ADB driver, since I got no connection before.

thanks for replying again
i tried to oem unlocking and usb debugging but unsucessful
furthermore my pc cant even recognise my phone when i turn on usb debugging or change the usb to media transfer protocol (mtp) mode after i flash stock firmware (it worked before i flash the firmware)
how am i gonna install anything if my pc cant even recognise my phone????
(ps: your question "how far did you get" my answer is i cant flash any mods or unlock anything. bootloader locked.)
Can you see the "developer options" in settings/system when scrolling down ? If not, then:
How to access developer options in Android
Step 1: Go to Settings > About Phone.
Step 2: Tap Software Info > Build Number.
Step 3: Tap Build Number seven times. ...
Step 4: Once developer options are activated, you will see a message that reads, You are now a developer.
Within developer options there are options to enable usb debugging and oem unlock. I recently did this on a Galaxy tab and saw..nothing.
First I had to establish a network connection to my wifi base. Weird, but this brought those wanted menu items...
For further connection, check your computer drivers. Both the manufacturers usb drivers and adb driver are necessary. While connected to a PC, check, if you´re on Windows, the device manager, if the proper driver is chosen.

I see the developer options and the usb debugging switch
But there are 2 problems
1. My pc running windows 10 cannot detect my device (like showing it as a disk so i can copy files to )
2. In developer setting there is no OEM unlock option, which is weird. I triee many solutions but cannot get acess to OEM unlock. I even tried to unlock it with ADB ut its useless since my phone cant even access fastboot mode.(download mode is considered to be fastboot but ADB wont recognise my phone)

On any other device, you would have enjoyed your new TWRP since several days. But Samsung is eager to build as many hurdles as possible, to prevent changing the original software. They invented "KnoxGuard" to "protect" the phone. In your case, it´s aprotection against it´s owner
The error message means, that your phone isn´t successfully unlocked.
Try this:
"FIXED IT!!
The time trick actually worked.
All I had to do was turn back the time by like a year, reboot, enter recovery mode, delete cache, re-enable OEM unlock, spam the update phone button, and boot into download mode!"

oem unlocking dissapeared. model sm-A105GS/DS After attempted flash. (SOLVED)

the idea is to simply deggogle my a10. i found a few videos on how to do it. however i took the liberty of making a note of the base build number and after searching the internet, i found a firmware farchive that contained several md5 files. i figured i may need this in case anything went wrong.
so i went into settings and developer mode, turned on unlocking oem and usb debugging and attempted to flash the phone by booting into rescue mode (power off phone then power on while holding the volume up button) then selecting boot into bootlader from the menu before using a toll called odin on my pc, which given the threads i've seen on here, most of you are aware odin. i tried to flash the tar file reccomended on the site. odin reported failure. so without rebooting i flashed the firmware that matched my phone my selcting the respective md5 files and telling odin to do it. it reported neither success nor failure but gave a message of something like cs select. i have no idea what that means. however on rebooting the phone it booted fine. no errors or anything, just a completely reset phone. I like to add that this is not may main phone as i am a newbie on this area and wouldn't be so reckless as to experiment on my main phone. hower there is an app on there now called lazade which i beleiv is a shopping app based in the asian continent which isn't where i'm from. i unlocked developer mode once again as it had reset and found that the unlock oem option is missing. is it becasuse of the firmware i burned on it and to i need to reburn another? or is ther another way to get it back?
the baseband version is a105gdxu8cvg2
android 11
one ui 3.1
Your post isn't very clear....have you been able to unlock your bootloader?
The OEM Unlock toggle often disappears if 1) the bootloader is already unlocked, or 2) the system has not yet verified whether OEM unlocking is allowed. This is most likely not a firmware issue.

it's an old phone. i've had it for a number of years, but i got a new phone recently so i took the oppounity to attempt to degoogle my old one. apparently there's more than one way to do this One is to replace android with other operating system. if youtube is to be beleived. i doubt the phone needs veryfying as it's an old phone although the firmware is fresh. perhaps it is unlocked. in tairness i don't know how to determine that.

The best I can suggest is to flash a LineageOS GSI without Gapps. There are other custom ROMs available that are sanitized of all Google services.

Just Google LineageOS, they have a website. You should be able to flash a GSI image via TWRP.

Assuming your bootloader is already unlocked, here is the TWRP thread for your device., which you probably could have found by searching. Instructions for flashing are in that thread. And here is the LineageOS 19.x GSI thread.
If you haven't unlocked your bootloader yet, that's your first step. Some devices are not bootloader unlockable.

i don't know if i have yet. i went though a process and now the oem unlocking option disappeared ffrom the developer menu. i can boot into the bootload from the rescue menu. I assume that's what you mean.

When you're in download mode, you should see OEM LOCK among the text in the upper right of the screen. If this says ON, your bootloader is locked.

oem lock onu1)
looks like it's on. how do i disable it for this phone?
Turn the phone completely off, and leave it off for a few minutes. Then, while holding both Volume buttons together, plug in the USB cable. The device should start in Download mode. Hold Volume + until the bootloader unlock screen appears, then follow the prompt to unlock your bootloader. This will wipe data.

never shows up. i get to the download screen but pressing the vol up keys doesn't do anything. not even adb can see the device. use debugging is turned on. and usb mode is set to file transfer mode. it weorked finde before i reflashed it. perhaps i need another version of the firmware
development, i noticed the wifi wasn't turned on. i turned it on the went into the development mode. unlock oem was there and ticked
so i did what you said again, this time the option for unlocking oem in download was present. i followed the instructions. it booted and came telling me the oem is unlocked and won't be able to verify the intergrty of the os. now it's doing a reset. i think we got here. what next? you you said twrp?

ADB only works in Android or in recovery mode. Samsung devices don't have a fastboot mode.

Yep. Since you don't already have TWRP installed, follow "Method 2" in the thread I linked.

yep it does. i had a little bit of trouble between installing the first and second file. it kept reporting a corrupt operating system but i noteiced it cycled a reboot wo i held hte power and volume up buttons together when it cycled. this allowed me into rescue mode. from there i was able to power down the phone so i could reboot it back into download mode then upload the rescue file contained in the zip file mentioned. after that it booted ok but keeps claiming that the operating system isn''t offician but then boots into android ok. i expect installing the disable_drm_very app wil fix that. then i can try installign a new os.
but that's for tomorrow

Question Stuck in dm-verity curruption screen

Hi all,
my wifes phone was stuck in a bootloop at the MIUI logo (phone is full stock original, no changes at all).
All options with the buttons (rebbot,safe mode, wipe all data) did no work. Battery drain also not.
I tried to reboot via "Minimal ADB an Fastboot" and since then I get the message -> dm-verity curruption on the POCO Screen. If I press POWER within 5s, the message disappears and phone is stuck on the POCO screen forever, not even booting to the MIUI logo anymore.
I tried to flash the exact same version of the recovery ROM that is on the phone via MIFlashPro -> did not change anything.
Is there a solution to flash the original firmware to the phone? Like a "full reset"? I am able to enter the red FastBoot logo with the buttons.
Thanks for every help
Is the bootloader unlocked?

They said “no changes at all”. Nobody unlocks bootloader for sh-ts and giggles.

Yes they do. I enable it as soon as I get any device. Multiple years before I rooted. Why wouldn’t I .
They're trying to flash stuff, so asking if the bootloader is unlocked is a reasonable question. But to answer your question, most users don't enable USB debugging. MIUI warns users that it's a bad idea, which is enough to put many people off, and this is sensible if you don't need to use it as it's a security risk (see this paper for some clear examples).
