[Huawei Mate 20 Pro Guides, News, & Discussion] David Horn:
I would suggest that you don't bother with the debloating. Mate 20 Pro is fast enough and there appears little thought given to interactions and consequences to removing so many system apps. I have no doubt it'll work, but I'd expect a massive headache if you need to do anything in settings afterward (it looks like this might break the wallpaper picker, anything related to accounts, cloud, backups, possibly Google Pay, GameTurbo, call recording, and the ability to update the few Huawei apps you have left after running the script.

This is less breaky.
