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.
