I did a clean install now. Bliss launcher still crashes, even before set up really starts (at language selection). After start up configuration, bliss stays crashed. Settings app can be opened from the notification bar, but I wasn’t able to restart the bliss launcher this way.
I will test your e-2.0-T-build next and report over at that thread.
try taking a backup of /data using TWRP
I tried that, but a backup of 2.3 GB to the sd card wasn’t done after over 2 hours and I didn’t even have many apps installed. I lost patience after that and gave up.
EDIT: I lost track of what thread I’m in. This report is to your e-2.0-s build from over at this thread. Sorry for the confusion. Feedback for the T build will be my next post right here in this thread.
