OxygenOS 11.3 A.15 EU Full Stock Firmware for OnePlus Nord 2

Requirements :



Instructions :

  1. Download the .zip and the latest version of PartitionsBackupper.
  2. Download A.15 Firmware, extract it and put all files in the PartitionsBackupper folder.
  3. Reboot your phone in fastboot mode (Power off, than power button + volume down)
  4. Run PartitionsBackupper.bat, choosing the restore option, to flash all partitions with fastboot.
  5. I reccomend to do a full data format with the stock recovery before going back messing around. It usually wipes better than TWRP.
  6. Type on command line "fastboot flashing lock"
  7. Enjoy your brand new OPNord2.

Can i reflash stock oxygenOS rom and return completely stock without locking the bootloader? I flashed elixir, but the wifi doesn't work, so i would like to turn on stock, maybe doing root and installing magisk, viper ecc... Is there a complete oxygen that i can flash with maybe sideload on twrp or things like that?

If you use this, you must unlock bootloader and install twrp aftet that.

I did it, and the bat told me he flashed everything without problem, but then it rebooted me to twrp, and my bootloader is still unlocked, but most importantly, when i go "reboot system" it stays on oneplus logo and no os start... So I'm semi bricked now without OS, at least I have twrp to make some experiment... ideas? I retry the same thing?

Edit: the phone booted... with Elixir OS (?) so nothing changed, still my wifi and bluetooth don't work...

Try ask in "nord 2 community" telegram group. They are really helpful.

Don't try restore your backup file. Try restore file unzipped of a.15 firmware, and you return to stock and lock bootloader

Please put the "PartitionsBackup" folder with all the partition images in the same directory of this script.

I have tried this and it worked, partly. The process stopped on flashing vendor and nothing happened for hours. So I disconnected the phone and it boots fine. I can set up everything, but updates fails. It's now on A15 and will not update. I have also tried to lock the bootloader again, but then the phone won't boot at all, something about an error to boot/system. If I unlock the bootloader, it works again.

Something is clearly wrong here. How can I restore my device back to full working stock again?

I was on A17 before installing TWRP + PixelExperience Rom. But when I wanted to return to stock all hell broke loose 😩
