7T stuck in recovery after OTA update Android 12 - OnePlus 7T Questions & Answers

Hello people!
Yesterday my Oneplus 7T informed me about the new OTA update to Android 12. I downloaded and installed the update, battery was >90%. Then I did the required restart but the phone was not booting again. After that I tried entering recovery mode (Volume up + power button) which was succesfull, but from this point there is no way to get the phone booting up normally.
I can enter the Recovery Mode or the Fastboot option.
I already wiped the cache, didn't help at all.
Boot reason shows: init_user0_failed.
Is there any way to get access to my data again or to boot up the system?
The phone is not rooted or anything like this. This is why I'm wondering how this could happen...I mean this was an official system update by Oneplus and it killed my phone...
Thankfull for any answers.

Find out which slot the phone is trying to boot to and see if you can buy to the other.
If so, boot into that slot and redo the update with the full package instead of the update package
This post give instructions on how to do find out & switch the boot slot

The active slot right now is B. But when I try these commands:
$ fastboot --set-active=a
or
$ fastboot -aa
Should set the active slot to A.
Similarly
$ fastboot --set-active=b
or
$ fastboot -ab
Should set the active slot to B.
...it always says, that this is an unknown option
EDIT: Had to add ./ before command, but now it says
'Slot Change is not allowed in Lock State'

Ah, forgot that your bootloader was locked.
If you can get into recovery you might try a factory reset, but that will wipe your data

Yeah the factory reset worked, sadly all data is gone. Guess I'm cured from Oneplus for the future. Really wtf..
BTW After factory reset I tried to install the Android 12 update via local update to avoid OTA. Same picture, it also results in not booting again.
But thanks anyway for your helpand fast reply!

[TUTORIAL] Complete Guide on How to Flash English Rom to China Local Huawei Watch

You could have been frustrated with all the features that’s supposed to be in your New Huawei Watch is nowhere to be found. Like Wi-Fi, Bluetooth and Language Selection are all hidden in the China Stable Rom of the Huawei Watch.
I have talked to the CSR of Huawei in China, they honestly told me that the Wi-Fi certificate for the watch is not yet certified that’s why they cannot unleash it yet but it is embedded inside the watch should future updates allows the Wi-Fi to be used. Regarding the language selection, local China release is locked to Simplified Chinese, whether you like it or not.
If you happen to buy from China or received a gift with a China local release Huawei Watch, here is the guide on how to flash with an English Rom which I have already tested mine on.
Here is the complete guide:
Step 1: Put the Watch to Fastboot Mode
1) Hold down the power button
2) The screen will go black for about 2 seconds and then boot into the Huawei logo. Keep holding down the power button.
3) Wait for the first vibration, release the power button and then immediately give the power button one short press.
Note: If you feel the second vibration, you waited too long to do the release and press. Start over again with Step 1.
Another alternative for Step 1:
1.) Install ADB SETUP V1.3
https://drive.google.com/file/d/0B_1zjuazXSqbQ0p6NWtvRk9OMzA/edit
2.) Enable ADB and connect to computer
How to Enable ADB:
- Go to About
- Click 5 times on Build Number to access Developer Mode
- Go to Developer Options
- Enable ADB Debugging
3.) Go into command prompt mode
4.) Reboot watch into Fastboot mode using this code:
adb reboot-bootloader
Step 2: Unlock the Bootloader
1.) On command prompt mode, type this command: Fastboot Oem Unlock
2.) accept the prompt on the watch.
Note: If successful, command prompt will say your bootloader is already unlocked.
Step 3: Flashing
Download first the three files before proceeding:
Boot Img: https://mega.nz/#!rgRQHRrb!lgQCvqH-qkuqitPRRXfCad29MdmJ6ynaUHJDr0hjeLM
Recovery Img: https://mega.nz/#!ahgjxA4R!y8Hb0CBVBRwUr0tA3HeFrrqh0ALAiMyqJu0pLsBsAD8
System Img: https://mega.nz/#!2pYVBDpA!wQJT8LDcffk7uxEmrsqna6MKWIODD-FqBO_k4Poml7g
After downloading the three files, lets proceed:
1.) While on Fastboot mode, type this on the command prompt one at a time:
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
2.) and then go to recovery and do a wipe data / factory reset.
Congrats! Your done!
Further Reading if you are stuck on flashing System.img
There are some reason beyond my explanation why the system.img cannot be flashed to the watch, here is the workaround:
1.) First of all download the TWRP and fastboot boot it:
TWRP download: http://forum.xda-developers.com/attachment.php?attachmentid=3505656&d=1444766757
Code:
fastboot boot TWRP2.8.7.0-Sturgeon.img
2.) Now your watch is in TWRP and you can no longer use ADB commands, go to your watch and select Advanced, then select ADB Side Load
3.) Going back to command prompt, push the system.img in the sdcard so:
Code:
adb push system.img /sdcard/
4.) Now flash it:
Code:
adb shell dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
5.) Reboot.
Now you may encounter bootloop after flashing which I did, go back to Step 1 Fastboot mode and select Reboot Recovery, then wipe data and then clear cache, then you are good to go!
This is the most complete guide I can come up with based on my own explorations. Hope this helps.
Where can i find the drivers for this watch.
When i plug this watch into my computer Windows doesn't detect the drivers. I've tried looking on the HuaWei website but there are no downloadable drivers. Any help?

Look here : https://m.reddit.com/r/hwatch/comments/3n9ckp/how_to_get_adb_access_over_usb/
"Fastboot Oem Unlock" should be "fastboot oem unlock" otherwise it won't work. Also make sure to have ADB 1.0.32 at least for watches!
hello!
i do all step and complete flash with twrp mode . but when reboot and will go to reboot recovery the watch restart and restart!
sry for weak english!

Hi, first of all thanks for this awesome guide.
This is the first thing I am looking for after bought a Chinese watch from China.
Manage to go through ONLY I tried key in "fastboot oem unlock' all in small letters.
Then follow the guide instruction to goto recovery to wipe data after successfully go through the other flashing steps smoothly.
This is where I got stuck in infinite looping in Android lying and screen flashing every few seconds. I got panicked after trying multiple times failed to recover from this symptoms for a while.
Until finally manage to pull back to fastboot menu by keep press holding onto the power button. The steps of holding till first vibration then do a quick short press doesnt work.
I am glad that now I am back to normal with the English screen.
Next I will proceed to flash the TWRP and 1.4 update.
Hopefully everything goes smoothly.
Thank you for the guide once again and wish everyone success in updating and Enjoy!
Update: (9:29am)
Did a system update. Before was something like LBC49A, after system update it becomes LBC43B. I suppose this is 1.4 update as the name is the same.
Hence decided not to flash the TWRP recovery for the time being if it can continue auto system update.
Update (9/3/2016):
Sorry, nvr read through all the posts. Was thinking that (LBC43B) was the latest update.
So proceed to flash TWRP recovery then try to update to MEC23L (latest update) but failed to run "adb sideload update.zip"
Every time once enter into Recovery mode, the connection dropped. Then tried to do OTA update by factory reset as suggested but failed (confirmed my location can OTA as one use from same location didi it.)
This morning went back to PC flash back the original Stock Recovery from here.
Restart the watch and goto System Update, receive message "Charge the watch to update to MEC23L"
My thot - OTA only allow with Stock Recovery?
Update done but still cannot sms. ??
Btw, for LBC43B, many functions cannot work properly like sms, call and no sound at all. Thx n Enjoy.
P.S. Using Minimal ADB and Fastboot, PDAnet driver(for watch USB driver), running on Win7, connect via watch USB charge docking station.
help me please
No OS installed! Are you sure you wish to reboot?
This is my problem, I can´t install it-
I send you a private message Richboy234, can you help me please?

Hi there
All i know is you can flash the stock rom then update via OTA
mine is running marshmallow already now MEC23L
This is the safer way coz i never tried to flash in the MEC23L

hi there
i think you need to do a further reading on the one after step three
there are chances that you will get stuck in flashing the system image file
there is a workaround.
try it again

Hello,
I'm also encountering this error. I did try the first method, and I'm getting stuck on activating ADB Side Load. Any tips?
Hi, there's a problem and i can't mount partition /data and /cache
plz help
Thanks a lot man you are a gem
I in hurry formatted system from twrp and was without OS. very detailed tutorial for beginners with adb. I am back with watch booting fine now
Just a note. I tried doing this while in China without vpn access for my phone. This made it so I couldn't sync up or pair because it kept trying to access google which was blocked. Once I got back to Canada I was able to do everything and update to newest OTA. If you leave it on chinese rom you can use in china and pair with the Android Wear China version app.

Not sure if he got back to you. I had the same problem, and it involved the system.img that I downloaded from the link above. It wasn't complete for some reason. On this thread attached, it has a zip that has it all. My watch works fine now. I want to thank the OP here for showing me the steps to take. You all ROCK!

Honor 7x with Lineage and TWRP, stuck in limbo

Hi all,
I installed TWRP on my Honor 7x, that went well.
Yesterday I decided to try to get Lineage working so:
- I installed EMUI 8, that went pretty smooth
- I installed Lineage OS 15.1. (without GApps)
- I flashed TWRP.
The issue I have now is that:
1) I can't install any APK in Lineage. Probably needs a factory reset/dalvik cache wipe.
2) I can't boot into TWRP. It stays stuck on the splash screen forever. This also means I can't install OpenGapps, SuperUser access (afaik), or anything else that requires root.
3) The bootloader is saying "FRP: Locked", which means I can't flash a new TWRP or a different ROM. When I try it fails with "command not allowed"
3) "fastboot oem unlock" fails saying I need to enable it in the developer options, but it's grayed out in the developer options because it's already unlocked.
4) I wanted to try the "dload" method but I can't find a good explanation on how to do it, and Huawei recently took all their downloads down, which means I can't find any UPDATE.app even if I knew how.
5) The other solution that *might* work is using "fastboot oem frp-unlock", but I need an unlock code for that (I assume the same one that you request for an OEM unlock from Huawei), and Huawei closed down the site that generated the codes.
So I'm stuck in a weird limbo where I can't move forward (install Gapps and use my phone as normal) nor backwards (go back to EMUI8).
Does anyone have any idea how I can fix this situation?

small chance you enable root from developer options. (i think it will be adb only)
if so , maybe can use adb shell and "dd" to write recovery to correct partition.
problem is many of the available twrp do not boot on custom rom .
example code. (if you do wrong , it may be bad)
Code:
dd if=/ext_sdcard/twrp_Recovery_ramdisk.img of=/dev/block/mmcblk0p32
It seems like I'm allowed to use dd in ADB shell, but before I run it, what do you mean by " problem is many of the available twrp do not boot on custom rom . "? I thought recovery was independent of the ROM? And does it mean flashing twrp like that could brick my phone?

Like what you have , twrp stuck on splash screen
I managed to unlock the FRP with DC-unlocker. Sucks that it costs money but it worked!
Now Im stuck in a TWRP boot loop though.

At this point you should have access to fastboot though, right? I'd try a different TWRP instead. Perhaps try this one: https://drive.google.com/file/d/1ZYo7Ndte3vlLcUSadD6jIgfBi1oxa0Pb/view?usp=drivesdk
Just to clarify, it gets stuck on TWRP splash screen. When I turn off the phone, it immediately boots up again into TWRP. I tried getting into fastboot mode with all kinds of combinations of button presses, but no luck. Not even Volume Up + USB cable works

Sorry, only saw your answer after sending my other reply. In theory I should have access to fastboot mode. However, everytime I start up I get into TWRP, which doesn't work. I tried Volume up, volume down, both, with and without power button, with and without cable, and no dice.

This is because after the frp unlock, it needed to see a factory reset, and it usually needs to be done with stock recvery.
So will have to wait till battery is dead and and plug in usb while holding volume button. Should then load to fastboot. Where it is best to flash stock recovery to clear the recovery bootloop. The bootloop is do to the fact yo unlocked frp and now phone needs to wipe/data

i just took mine apart and discconected the battery and still no luck that program deleted my fastboot
Please can you tell me the process to install twrp I have the L24
I waited all the way till the battery drained, stuck in the USB, and it booted to ROM! Sadly it immediately shut off again because the battery is dead (even with keeping the USB in). I'm going to keep trying though.
I can't get into fastboot mode. I can get into the ROM by letting the battery drain completely on the TWRP splashscreen, and then sticking in the USB cable. However, no button combination or "adb reboot bootloader" or rebooting to bootloader from the ROM brings me to the bootloader. I wonder if it's still there. Any ideas?

Seems to be a f-up situation either way.
You have adb DD available, found out before.
Don't know if maybe flashing stock recovery is good idea at this point.
I think fastboot.img can be flashed with DD too, but don't try till someone can confirm.
If flash stock recovery clears the loops, maybe best to do full-ota manual flashing.
I managed to get an UPDATE.APP file and extract fastboot.img from it, as well as all the other .img files. If someone can tell me what to flash and how (with dd), I think Im set.

Fastboot.img is the large part the bootloader. If flashing it goes bad, might be dead phone after, just rember that.
Will add a list of partition names and command s for you soon.
here is a list of oreo partitions and there /dev/blk/** number
and here is an example of code to save images with dd assuming you put the images on your extrnal-sdcard in folder called oreo-images
Code:
dd if=/dev/block/mmcblk0p5 of=/mnt/ext_sdcard/oreo-images/fastboot.img
Do that save first and compare the md5 of the file from update.app to this file.
or just check the md5 before making the copy
Code:
adb shell md5sum /dev/block/mmcblk0p5
If you are conviced you need to flash the images, here is example of writing the image assuming files are in sdcard folder oreo-update-images
Code:
dd if=/mnt/ext_sdcard/oreoupdate-images/fastboot.img of=/dev/block/mmcblk0p5
As I have said, this might be bad advise , I have not done fastboot.img flashing before. But on other devices it is same as lk.img or uboot.img, There is danger in flashing it incorrectly. That is why my suggestion was to flash no-check-recovery and do manael update with "echo -update_package" commands.
Along with the statement that fastboot.img is similar to lk.img or uboot.img on other phones, Your fastboot cannot be gone. because phone boots.
but do let us know how it goes.
I agree it would be better to flash recovery if possible. I assume I need the NoCheck-Recovery image from this thread? https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044
And what partition do I have to flash it to? I'm guessing either /dev/block/mmcblk0p28 (erecovery ramdisk) or /dev/block/mmcblk0p32 (recovery ramdisk)? I'm not sure what the difference is between erecovery and normal recovery.
(didn't flash fastboot yet, wanted to see if recovery was doable).

To recovery_ramdisk. 32
What about check md5 of fastboot partition, that will be helpful to know if it did get wiped out.?
Hmm seems like I'm not allowed to use dd after all:
HWBND-H:/ $ dd if=/storage/7C96-7E17/BND-RECOVERY-NoCheck.img of=/dev/block/mmcblk0p32
dd: /dev/block/mmcblk0p32: Permission denied
And here I was thinking I was close to solving it...
Also can't run md5sum on the fastboot partition, since that needs root as well.

Device State: Error! (stuck in Fast boot mode after Android 11 update)

Hi All
Apologies if this already has a thread, noob here.
Okay so I updated to Android 11 about 45 mins ago, Phone restarted seemingly fine and asked for my pin number so I typed it in...
Wrong Pin (definitely typed the right pin)
Okay so I've has this issues before post updating but I couldn't remember how I fixed it so I jumped on Google and searched for a fix. Someone suggested restarting in safe mode. Okay so I hold the power button then hold on restart until it asked me if I want to restart in safe mode. Yes please. Fastboot starts, I get the options to start but everything I select loops me back to fastboot mode along with the following worrying messages:
NOS Production: Error
Device State: Error!
Enter Reason : failed to load/verify boot images
I've seen in another thread the suggestion to leave the battery to drain overnight then to try booting . Can anyone confirm if this is the only solution or if there is alternative option?
Thanks
If I were you, I would download the full factory image for android 11 and do an install from fastboot. It seems the boot partition is corrupted.
Remember to remove the "-w" flag from flash-all.sh so your data is not deleted. Let me know if it works. The fact that you can access fastboot is a good sign!

I got same issue, any solution?!
i have this problem too when i update to android 11 via OTA or flash stock image from fastboot ,
always get back to fastboot with "error setup KM" or "failed or load/verify boot images"
the solution for me is to flash android 10 image via fastboot, so i can't update to android 11

Did you ever figure this out? android 11 seems to have messed up my boot_a and boot_b, boot b seems to work fine I can enter recovery on it, but I can't switch to boot a it says directory not found or something, and when booting up I get fastboot mode: error boot prepare on boot a. how do I just completely reset everything and start clean? or do I gotta go back to android 10?

I think this related to emmc defect, because when i ask vendor to replace with new unit the problem gone, there's nothing you can do instead go back to android 10 or try flash android 12 beta and see it can boot

quoting from your answer , is it true that removing -w in the command will not delete existing data?

Fairphone 4 stuck in bootloader mode - bootloader unlock

Hello,
I got my Fairphone stolen and I had to get a new one and re-config my os onto it (I had Iodéos).
I followed the official instruction here https://iode.tech/en/iodeos-installation/#1648127755024-cd19692f-431b but got stuck when my phone never reached recovery mode. It is now stuck in the bootloader menu (Start/ Restart to bootloader/ Recovery mode/ Power off/ FFBM/ QMMI) and whatever the option I chose I keep comming back to this screen. The phone don't start normally anymore. The bootloader is unlocked and I never locked it before finishing the installation as I read it can brick the phone, still I'm stuck here. I tried everything I found on the internet (removing the battery and waiting etc). Fastboot commands work fine. Adb commands obviously does not. I'm kind of desperate... Any ideas ?
Thanks a lot in advance !
Better late than never.. when in fastboot mode run command:
Code:
fastboot --set-active=a
Then reboot.

Thanks ! I had already done this without result.
But I solved it by flashing FPOS to get out of the bootloop and flashing iodéOS after.
All the steps here if it can help someone.

Can I recover data from a Oneplus 7t phone with locked bootloader?

I restarted my phone after being prompted to by a recent update. For a while the phone was stuck in a loop of booting to the android screen followed by the magenta tmobile screen before starting the process again over the course of 5 min.
Now the phone only boots into the recovery mode menu(?). The black screen with the oneplus logo that prompts you to pick a language before giving you the options of "view boot reason", "wipe data and cache", "advanced", and "exit" on the next screen.
View boot reason just says init_user0 failed.
I have wiped the cache and restarted, still boots into the recovery menu regardless.
I can boot into fastboot, but I do not have the bootloader unlocked. With the bootloader locked that means I cannot boot twrp recovery image from what I understand? And then unlocking the bootloader wipes the data.
I have managed to boot into EDL mode as well and the phone will show up as connected in the MSMDownload tool.
ADB does not work as far as I know since my phone no longer boots into android. (It displays the qualcomm snapdragon logo briefly before showing the aforementioned recovery menu).
Is there anything I can do recover my data given the above information? I have reached out to oneplus support as well and they said they'd get a more specialized person to reply to my case in 6-7 hours. Thanks for any help.

Correct.
Also from what I understand, you cannot 'pull' files from internal storage from Fastboot mode, contrary to ADB mode (unless I am wrong).
Maybe you could try switching 'Active Slots' in Fastboot mode? With a little luck the other slot may still be bootable. It is not clear if this command will be permitted with stock ROM. You can do a little research but the fastboot commands should be:
fastboot getvar current-slot
fastboot set_active a (or b depending)
fastboot reboot

Thanks for the info. I gave that a shot after and unfortunately it said Slot change is not allowed in lock state. Oneplus support did get back to me and said I'd have to send the phone in for repair. They said the device data is likely lost though so I'm not sure if it's worth sending it in vs just wiping and all that myself.
