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
Download the zip;
Unpack the zip in a folder;
Reboot the OnePlus 8 Pro in fastboot-bootloader mode (Power and volume + and volume-);
Connect the OnePlus 8 Pro to PC;
Run flash-all.bat flasher you need;
Wait until the process end;
The phone will automatically reboot.

REMEMBER
"Invalid sparce file format at header magic" is not an error, you need to wait a bit when you see that string, just wait.

If the device automatically reboot in Stock Recovery mode don't reboot it and wait the flash end.

These ROMs can't be used to update or downgrade your phone but just to restore your phone.

If the rom seems doesn't start go in recovery stock and follow this guideline: English -> Wipe data and cache -> Erase everything.

If you want to rebrand your phone from HydrogenOS to OxygenOS you can follow this guide: Rebrand Guide

If you want you can use also my tool to flash Factory Images, unlock bootloader, flash twrp or to understand if the device is recognized: https://toolaio.tk/

This might be a stupid question, but will twrp recovery ever be available to flash custom ROMs down the road, or is it just not possible on the OP8Pro?

If I substituted a magisk patched boot.img in the fastboot rom and flashed it via flash-all command, will it flash the stock rom and root it at the same time?
