Ubuntu – Ubuntu Touch (of Aquaris E4.5 Ubuntu Edition) freezes when booting up

After I fully charged and rebooted my Aquaris E4.5 Ubuntu Edition, it freezed instantly. I am not able to complete any touch gesture.

When I try to boot 'recovery' (Volume Up + Power), it will boot regularly without any change.

Can I reset my phone by connecting it via USB to an PC??

Best Answer

Yes. The standard recovery image does not permit adb access, so you need to supply one to ubuntu-device-flash which will allow adb to work. This image is a good choice:

You can then type

ubuntu-device-flash touch --bootstrap --channel ubuntu-touch/stable/bq-aquaris.en --recovery-image recovery.img

Which will reset your phone (including a data wipe!) to factory state.
