i am also having the problem with installing /e/. It canceled while installing on mi mix2 with incompatbility error. It says i need Firmware 9.5. Coming from Lineage 15.1 android 8.
The highest Firmware Version i found, includet in actually newest Xiaomi Chiron (2020/05/08) Official Rom, is 9.1, if its true. So there will be no choice to install. Do i have to process this in the same way like it was desceibed above?
I am also horrified to repeate it to every new update installation. But there is no alternativ to go back to the goo…e spyware. Does somebody else has installed /e/ on chiron and knows the problem?
