[Xiaomi Mi 9 Guides, News, & Discussion] TheGrave:
I allowed myself modifying this script a bit for my Redmi 9 MIUI 11 Android 10 needs. Some stuff is disabled to be on the safe side but some extra bloatware provisioned by Xiaomi is added at the end of the script (Google One, Google Pay and whatnot). I've found the script breaks my Home Screen setting of using App Drawer (which is easily fixed via the menus). Apart from that I haven't spotted other problems so far. Will report if I do so.
