Scenario in short:
I’m trying to install LineageOS onto a spare phone that I have (redmi note 8T) Hoping to get a daily driver out of it. The installation process requires me to install Android11 to install lineage on top of /over that. Which afaik isn’t directly available outside of some websites that I’ve never heard of.
For safety’s sake: would the install of lineage wipe the install of Android11? Or could there still remain backdoors?


I don’t have the device with me currently but if I recall correctly I think it’s at a lower version and it wants to update to 15. (Or it already is at 15…) I don’t know how I got there, haven’t looked at the thing in a year or two.
I don’t suppose there’s a way to downgrade to 11 from the OS itself?
