When can i use twrp oneplus 8 pro Android 11 ?Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via recovery (either stock) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlocked. This will erase all your data and will wipe your internal storage.
HOW TO FLASH
This version is only for not branded devices

Unpack the zip in a folder;
Reboot the OnePlus 8 Pro in fastboot-bootloader mode (Power and volume + and volume-);

Wait until the process end;
The phone will automatically reboot.
