Ubuntu – Ubuntu touch on Nexus 4 fails to boot

bootnexus-4ubuntu-touch

Last week I tried Ubuntu Touch on my Nexus 4, and it was easy to install en to recover to android. So today I wanted to show the preview to some friends, and something has gone very wrong.


Current status:

On boot I get a black screen

bootloader does work (volume down + power on)

Recovery mode gives me black screen


What I have done:

1 Updated my system (sudo apt-get update)

2 Installed (sudo phablet-flash -b)

After that my phone hang on the Google logo while booting.
Started recovery mode and started poking around. <- probably my first mistake.

3 Tried to reinstall (sudo phablet-flash -b) but didn't work. Gave error that I should use -d.

4 Tried reinstall with (phablet-flash -d grouper -b).


Can someone help me out on getting android back on my phone, because I don't know what to do.
"adb devices" tells me that there are no devices attached, so I really dont know how to reinstall or recover.

Just for your information. In the Release Notes, Device Specific Issues, there is a paragraph for the Nexus4

In rare circumstances, the Nexus4 may get into a state where it may not boot at all after the battery is drained (even into recovery). If this happens, the only way to restore it is to disassemble the back of the phone and unplug/plug the battery connector. See Power Consumption to learn how to avoid discharging the phone completely.
