Earlier we shared a tutorial about installing Lineage ROM on Huawei P20 Pro here. In this tutorial, we will guide you on how to install Resurrection Remix OS on Huawei P20 Pro. This should work on all variants of Huawei P20 Pro (CT-L29/L09/L04 etc). This ROM only works on EMUI9.1/EMUI9.0 based devices. You can not unlock the bootloader with EMUI10 so for that reason you can not install any GSI ROM on EMUI10. You must unlock the bootloader of your phone in order to install this custom ROM.

Disclaimer:

• Everything you do with your phone is your own responsibility, we are not responsible for your mistakes
• Basic functions call/camera/messages etc tested by us, but if there is any bug we can not resolve.
• By unlocking the bootloader you will lose the warranty
