I started the Android 9 update last night, after the installation I was asked to restart, but ever since it repeatedly keeps restarting (screen says ‘fairphone powered by android’). I have tried to turn it off, let the battery die and turn it on again but it keeps trying to restart constantly. When I press the power button and the volume up button simultaneously the message ‘no command’ appears. When I press the power button and the volume up button briefly a menu in yellow and blue appears saying:
use volume up/down and power
Reboot system now
I can’t use my phone now since last night. What should I do now?
