Thank you!
I currently have SuperSU. But on the previous times I tried to uninstall it bootlooped the phone. Full wipe and clean ROM install will not clean it?
Thanks once again.
yes... full wipe will clean root
It's recommended wipe SYSTEM / DALVIK / CACHE ...
DATA partition is optional (if you wipe or format DATA / internal storage It will delete ALL files / personal settings. It's recommended at first time or when coming from stock or another ROM)...
your Mi Account Login/password/cell number and Google account are important
Steps:
1 - Do It a TWRP Nandroid backup... if possible copy It to a external storage / external SD Card
2 - Wipe SYSTEM / DALVIK / CACHE / DATA optional
3 - Install flasheable ROM zip and reboot
4 - Wait some minutes ... and reboot to TWRP recovery
5 - Install Magisk zip... reboot
6 - Check in Magisk Manager framework status and SafetyNet flag (It's necessary accept download FOSS "Google plug-in"... just press ok and download)
7 - Check status and Flag... If successful It will be "green" ...
8 - If "red" maybe Universal SafetyNet Fix v2 Beta 5 module would be passthrough the flag
PS. SafetyNet flag It's used by Google and others companies like Netflix, Snapchat, Financial apps to "secure devices and operations"
