Not exactly /e/OS related, but… with Essential stock Android Q I wasn’t able to boot into TWRP recovery (I think it wasn’t being installed successfully). After flashing Android Pie from Essential, TWRP sideloaded correctly and installing /e/OS (‘pie for mata’) went fine.
Me.I appreciate the work of “The LineageOS Project” very much and also sponsor individual maintainers. But while LOS’ own recovery does serve its OTA update purpose, touch-based TWRP is miles ahead both visually and in functionality.
The Team Win Recovery Project Update 2.1 from 1.1.x in 2012 has heralded a big change. Now only the 100% Android support is lacking.
