presently I purchased a BQ Aquaris E5 phone in a second hand shop with android on it.
After typing in a console:
volker@v____50:~$ sudo ubuntu-device-flash touch --channel=ubuntu-touch/stable/ubuntu --bootstrap
2016/10/30 17:41:10 Expecting the device to be in the bootloader... waiting
2016/10/30 17:41:10 Device is |MSM8916|
Device MSM8916 not found on server https://system-image.ubuntu.com channel ubuntu-touch/stable/ubuntu
volker@v____50:~$
Who can I solve the problem? I don’t want to use a google operating system ;-)
Thanks Volker
