ubuntu-device-flash fails nexus 4

Question

Phone Status: Ubuntu touch was installed, but i have to reinstall it because the Ubuntu install is broken.

Im unable to install Ubuntu Touch/Phone a second time, it always errors out with the following output:

I did wipe the /cache partition with the "Ubuntu Touch Recovery". This didnt help, so i did it with fastboot. Unfortunately neither this solved my issue.

It is possible to reinstall Android, but not Ubuntu Touch.

While in Recovery, "adb devices" only spits out ? and "no permissions".

How can i solve this issue and get Ubuntu Touch running again?

Answer 1

After locking + unlocking @ fastboot, getting root permissions @ android (su was missing), i was finally able to install ubuntu touch again.

When it booted to recovery, adb couldnt talk anymore to it, causing said error. Following the order above solved it.
