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??

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.


Try recovery with wipe/data factory reset option during boot before flashing device from image. I had to do this on same new phone :-(
