HI, again

I have had prbs with A.12 update - apps force close, sometimes OS doesn't accept my screen lock psw (numbers), sometimes stuck on boot, but I have been able to recover with force reboot. But now I am stuck on boot. Stuck where we have red dot and 2 white dots, it boots few times itself after waiting long time and then it boots to recovery (twrp).

Does your A.12 wipe/destroy user data? If it does perhaps I do factory reset and start from scrats. Or does anyone have idea how I can recover?

I tried to flash ota.zip (I have it stored) First I flashed A.11 boot.ini and then I tried to flash ota.zip but it end up with error 1. And before that there was message that system has been opened as R/W xx times. Last 29.11, unable to use metadata to correct errors. system partition fails to recover. (flashing done with TWRP).

Thank you

I didn't understood means u have used iso file and flashed it in Penddrive then how to use it on windows (I think it's for Ubuntu OS)

Also seffc image is from A12 I am. Using A13 can i use thats
[OnePlus Nord 2 5G] kkdamion:
the livedvd, you used it how?
[OnePlus Nord 2 5G] muppetz:
"Oxygen Updater" apk has a thread regarding A12 beta , you can download A11 rollback zip file from them but it will get you to A11 indian version .
[OnePlus Nord 2 5G] valfr7e:
Thanks for all the help, I followed all the instructions here and now I got back my phone with stock firm and flashing locked but now I cant set a lock screen password it just doesnt work. In some desesperate tries to recover the phone I've deleted locksettings.db I dont know if this can be the prob. Can anybody could share persist.img to reflash that partition on my phone? thanks
[OnePlus Nord 2 5G] kaiseryeahhh:
I have a problem, I have returned to the EU rom and perfect, when doing the flash lock, now it tells me that it can not boot.

The problem I have is that to enter fastboot I can only do it from adb (with the phone booted) with the buttons I am not able to enter fastboot (I can only go to recovery).

What can I do?
[OnePlus Nord 2 5G] Raygen:
The persist partition is unique to your phone only, you cannot flash one from another phone.

If you didn't make a backup of it, only way is to send it back for warranty.

For locking the bootloader you need to have everything stock, vbmeta included, or it will not boot telling you the boot partition is corrupted.

You should still be able to enter fastboot mode by disconnecting the usb cable (if connected) and hold Power + Vol- at boot.

If it's not working, try the related guides with Mtkclient.
[OnePlus Nord 2 5G] kaiseryeahhh:
In the end with the mtkclient live CD I was able to revive it.

Thank you very much.
[OnePlus Nord 2 5G] Quercy:
I need help. Once again my One Plus Nord 2 with root went into bootloop. But this time unable to access the fastboot. It does not see it. If I connect an old One Plus 5 it's ok. I tried your procedure to install MTKclient but I got the error 'File "C:\Users\Home\Downloads\mtkclient-main\mtk_gui", line 6, in <module> import mock ModuleNotFoundError: No module named ' mock" when I enter the command "python mtk_gui". An idea ? I installed another MTKclient tool but without GUI and it's ok I manage to launch the "python mtk payload" command without error and connect my smartphone in brom mode. But I want to be able to use your MTKclient. Thanks a lot for your help. I guess in my case I will have to use procedure 3 or 4???
[OnePlus Nord 2 5G] Raygen:
Looks like I've forgot to add a step in the installation guide, my bad. Please type "pip3 install -r requirements.txt" in the terminal before starting Mtkclient.

I'd suggest to go with the "fix corrupted fastboot partition" procedure yes.

I've also added a procedure for the bootloop issue with root

[OnePlus Nord 2 5G] Quercy:
Thank you Raygen I will try again. But my OnePlus is going to be repaired. I think during my testing mode connection BROM there was a power surge on during usb connection and now is dead and it will not power on. 😭

[OnePlus Nord 2 5G] Sjak Philipsen:
Help please!

I flashed the Pixel Experience on my Nord 2.

Then I wanted to go back to oxygen OS. I followed the procedure "flash stock firmware with unlocked bootloader"

I did not make a backup (yes I know).

I can get into fastboot mode and trwp recovery,

in Mtk client its stuck on preloader.

What can I do?
[OnePlus Nord 2 5G] Raygen:
Since fastboot is working, re-flashing the ROM through it doesn't change anything?

What's the issue with the installation, does it bootloops?

Mtkclient is stuck trying to flash preloader or is a connection issue with the device?
[OnePlus Nord 2 5G] Sjak Philipsen:
I got stuck in bootloop after the first try. The word android appeared on the screen for a while and than it rebooted.

Then I tried to sideload pixel experience via twrp en got again a bootloop.

So I thougt to revert to the method via mtk clien, but it cant connect because its waiting on preloader Vcom.
[OnePlus Nord 2 5G] Sjak Philipsen:
@Raygen . So now i once again have a bootloop where I get to the screen with the word android on it. The loop took aprox. 4-5 minutes.

I used the fastboot oem unlock and then used partionbackupper to restore.
[OnePlus Nord 2 5G] Raygen:
I cannot offer support for mtkclient myself. If the methods to fix the connections issue available in the main thread don't work, I suggest to search for a solution in the original GitHub project page.

If you find a fix, please report it here so I can add it to the main thread for future use.

As an alternative, you can use the old method, with the live DVD iso of Mtkclient.

Be sure you're rebooting the phone in BROM mode in the right way instead of Preloader mode
[OnePlus Nord 2 5G] dev-DaT:
I unbricked my phone a while ago with the partition backupper method, but now OTA update does not work due to a "verification error". Does anyone know how to fix it?
[OnePlus Nord 2 5G] Raygen:
Be sure you have flashed the stock vbmeta, or try to flash the patched one
[OnePlus Nord 2 5G] Neosphaler:
After hours of problem I simply follow MTk steps and it works like a charm, thanks you ! <3
[OnePlus Nord 2 5G] Sjak Philipsen:
I have given it up! I'm gonna see if Oneplus can fix it. Curious how much its gonna cost me...
[OnePlus Nord 2 5G] gawain.j:
Hi, I'm having the same problem as @dev-DaT, do you know where to find the original vbmeta img?
[OnePlus Nord 2 5G] Raygen:
The original vbmeta is already included in the rom, or can be extracted from the A.20 OTA package available here https://www.getdroidtips.com/oneplu...-file/#OnePlus-Nord-2-5G-Firmware-Flash-Files, or from the Oxygen Updater app
[OnePlus Nord 2 5G] gawain.j:
Thanks! I tried it but same result for me. I also tried with vbmeta from Malachite without success.

I flashed vbmeta.img from A.19 img as I am running A.19, should I flash A.20 vbmeta before running the OTA update?

EDIT :

So, I tried the OTA after flashing :

vbmeta stock A.19 : OTA failed

vbmeta stock A.20 : bootloop

vbmeta "malachite" : OTA failed

vbmeta_patched (from here: https://xdaforums.com/t/stock-full-rom-oxygenos_11-3_a-20-eu-dn2103-unbrick-guide.4366985/): OTA failed

Seems I won't be able to get A.20 with OTA
[OnePlus Nord 2 5G] Raygen:
You're good with the A.19 version. Vbmeta should automatically update to the A.20 version by the OTA.

If you're still having issues, you can try with the patched vbmeta version available in this thread, but it's probably the same from Malachite you tried. Or try to do the OTA in TWRP instead of the stock recovery.

Or well, directly flash the A.20 firmware entirely

Meaning: unbricking via mtkclient may no longer work once you update to Android 12.

Whether this really pertains to disabling volume buttons remains to be seen (I'm not flashing lk.bin from Android 12 update so as to avoid crippling my own device).

Can somebody who has updated to Android 12 confirm that mtkclient no longer works for you (= stuck in preloader VCOM)?

Oppo and Xiaomi are known to have deployed something similar in the past.

Thanks for your help. Once again my Oneplus is in bootloop. I wanted to fix it by restoring the firmware with MTKclient but I can't put the smartphone in brom mode. Vol + & - and power on keys then I connect the usb cable and there it starts in fastboot mode and not brom mode. I tried many times and it's the same. An idea ? Another problem I tried to work in fastboot mode with the PC but the PC does not see the smartphone. It does not respond to fastboot devices. Any idea to recover my smartphone is welcome. I have a full backup except /usr made with MTKClient. And it'snt a drivers problem because one hour before I have no problem to access to the smartphone in adb or fastboot mode.
[OnePlus Nord 2 5G] roldev:
Are you sure follow the exact procedure to enter to Brom mode? It's hard sometimes.

Reboot your phone in BROM mode by following the steps below:

Switch off your OnePlus Nord 2 5G smartphone > Connect the USB cable to the PC only. [Don’t connect to the phone right now]

Once the device is switched off completely, connect the USB cable to the phone and immediately press and hold all 3 buttons (Vol+, Vol-, and Power).

The device screen should remain completely black and Mtkclient should detect your phone and connect to it.

Once detected, you can release all the buttons immediately to proceed.

Hope this helps.

Myself sometimes need to change the laptop and OS. Found more reliable using win 10 with mtkclient.

Installed as per the instructions on its GitHub page.

Hope you'll fixed soon. Cheers!
[OnePlus Nord 2 5G] edulcorante1:
In my case: connect usb cable, volume + and - at the same time, enter the first phase of brom mode and then without disconnecting the phone, press volume + and - again with power, after about 30 seconds you will see how it starts the connection with ...data... the mtk client screen tells you connection mode brom connected

Don't root it with TWRP. Use magisk patched boot.img for root and will stay safe.
[OnePlus Nord 2 5G] Quercy:
Yes I know but with this smartphone everything is complicated when it is rooted. For example updates. You have to come back unrooted before doing the update and so on...This smartphone is clearly not made to be rooted and tinker with it 😭.

[OnePlus Nord 2 5G] Coconut_cube:
Took the time to confirm your findings. It's true as far as the code goes which I assume is UART strings but I could be wrong. Will keep this in mind in case I decide to update. I've read on various other forums that people are still able to create backups and restore them using mtkclient (read/write) after updating. If I had to make a guess, BROM mode is still accessible to those who have used mtkclient on their device at least once as it runs an exploit to permanently disable the usual BROM security locks (SLA, DAA, SBC, Mem read/write auth, etc.). It would seem that the efuse is only effective when those are still enabled. Again, this is a complete guess (probably completely wrong too) and I haven't done any device specific research.

I'm curious whether there is another way to access BROM mode, such as a different exploit or a test point on the mainboard but unfortunately I don't have the expertise to figure it out.

I would recommend this video to anybody interested in this sort of stuff. It's where I got most of my information from.
[OnePlus Nord 2 5G] ezdiy:
There's always a way - by removing storage during boot (shorting a CLK pin on eMMC or UFS.). I've seen youtube tutorials for some Oppo MTK phone already.

Volume button(s) is what preloader.bin checks, whether to jump *back* to BROM EDL mode, but initial BROM boot itself cares only about storage, it doesn't listen to buttons. Point being, you now have to disassemble the phone (and short proper pin) to use mtkclient.

Another hypothesis is that the code triggers only when the phone bootloader is in locked state.
[OnePlus Nord 2 5G] Coconut_cube:
Thanks for the info. I was under the impression that you boot directly into BROM. Things make more sense now that I know. I guess to really know under what circumstances the efuse gets tripped, the lk.bin file would have to be reverse engineered. Not the easiest thing to say the least. Unless somebody is willing to take up the task, for now we can only wait to see if any more reports of mtkclient not working come up.

By the way, how would you go about flashing the stock Android 12 update with the known good lk.bin?
