Been staying in China since 2020. Also a Oneplus user since OnePlus one. Give up Oneplus and swtiched to Nothing phone since Oneplus 10. Decided to try out OnePlus 11 and... ColorOS is really pain in the ....

Decided to play around with fastboot flasing this is what i mange to get.

Step 1:
Download all the usual tools
- Android SDK
- Get the firmware from this post

Step 2:
In most cases, a soft-bricked drive could already be in the Fastboot Mode. But if you’re stuck in a bootloop, long-press the Power key to turn it off. After that, press and hold the Power + Volume Down keys simultaneously to boot your device to Fastboot Mode.

If you aren’t able to power off the device, allow its battery to drain out. Once this happens, you should connect it to the charger. As soon as it is about to boot up, you should use the Power + Volume Up/Down keys and it’ll boot to the Fastboot Mode

Step 3:
To clear all user data

fastboot –w

Step 4:

Take note, most of the command i got it from this post , if there are missing files, replace tne extension from img to elf or mbn.

fastboot --set-active=a
