I tried to reinstall Ubutnu Touch on my BQ Aquaris 4.5. But the precess got stuck somewhere. So i tried to do it again, but i can't reach the device anymore. If it is in boot mode and i do "ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en --bootstrap" i only get "Expecting the device to be in the bootloader... waiting " . Nothing more ever happens than.
The device does not boot normal anymore. It gets stuck on the screen with the bq logo.
What can I do now ?
