Hi i recently bought the Asus ROG phone 2 Tencent edition, it came with WW rom 1908_12 but CN fingerprint. I followed the tutorial from Bobbyprats to fully convert it to global, unlocked bootloader etc. but after step 2 (the root part) when trying to boot the phone it says ''Slot A is unbootable''. I can still run the ''fastboot devices'' cmd and I can still see the fastboot menu. Now I read some other posts about this and I read that you need to flash the stock img again but since I don't have experience with flashing at all I am pretty clueless. Do I just connect the phone to my computer in fastboot mode and start adb&fastboot and use the ''fastboot flash boot bootstockww190812.img'' command? Thanks for the help.

Thanks for the fast reply! will it boot by itself? ADB says it finished but i still see the fastboot menu on my phone, do i just press start? Also is it normal that it only takes 3 seconds too finish that process?

> ROG2 Bootloader Unlocked.
> Download Stock.img of which firmware version you're on.
> switch the phone to fastboot mode
> launch adb > fastboot devices > alpha numeric should appear
> make sure stock.img is in the same folder as your adb
> fastboot flash boot stock.img
> fastboot restart

if above didn't work.
> download RAW Firmware
> Extract Content to a folder
> Switch phone to Fastboot mode
> double click Flash_all.bat
> Wait for process to finish
> Factory Wipe to boot

If Phone says LOCKED and you can't boot to system

you can unlock through EDL mode
