I tried to reinstall Ubuntu Touch to my BQ Aquaris E4.5 but something went wrong. I followed these steps: https://developer.ubuntu.com/en/start/ubuntu-for-devices/installing-ubuntu-for-devices/ .
Everything was fine until the last step. My phone just showed no reaction. I tried to do a full reset through recovery mode, but afterwards i was stuck in a bootloop. Now my PC does not recognize my phone anymore, the recovery mode isn't working (phone just restarts) and if i go in to fastboot mode it is displayed in the console (fastboot devices) but if i try to do something nothing ever happens. It's not even possible to turn the device of. It's just rebooting all the time (it boots to the 'bq'-logo then the screen goes of, it vibrates and reboots again).
So i waited like 6 hours until it runs out of battery but this didn't helped neither.
What can i do to come back to Android or Ubuntu? I don't care about my data. Just want my phone to work again :s
EDIT: OK it lokks like i can reach my phone now through 'ubuntu-device-flash' and 'fastboot'
but if i try
ubuntu-device-flash touch --channel=ubuntu-touch/stable/bq-aquaris.en --bootstrap --device krillin
i always get
Cache formatting was not successful, flashing may fail, check your partitions on device Can't boot recovery image
any idea how i can get rid of this?
i tried it with the recovery image from https://wiki.ubuntu.com/Touch/Devices#Working_with_ubuntu-device-flash:
