I haven’t used the phone for some time now, but it was on MIUI 11, so Android 10 if I’m not wrong. I didn’t know I had to go back to a previous official ROM/firmware before installing the /e/ ZIP, I wonder if it can be done by uploading just the firmware ZIP (which one, btw?) and installing it?
This was in fact a fresh install of /e/, I thought the available ZIPs were for that purpose. I was on MIUI 11, unlocked the phone, flashed TWRP recovery, wiped everything and tried to install /e/. Maybe the wiping wasn’t needed?
Do I have to start form other source point, there? Didn’t see that on the docs…
If the phone had Q on it please do not try a return to nougat or Oreo build. It could brick your phone. Most of the Xiaomi devices have this problem when downgrading to a previous version of the OS.
