Redmi Note 7 here...
Situation: I'm currently using the MIUI.11.2 (20.3.26) rooted. It's working completely fine, no issues at all. But I'm in need of reverting back to Android 9, and just wanted to try going back to MIUI 11.0 (stable).
Question: Without formating, can I flash this stable lower ROM version over my existing one, like doing an update process? I just don't want to reinstall all my stuff. I will of course back up all the info from OF recovery. And I assume the device won't be affected by ARB protection, as it was taken out from all the device's ROMs.
Thanks!
