I just tried to install Ubuntu Touch on my Nexus 10 according to your manual.
The terminal said at the end that I have to wait for a reboot of my Nexus 10 and afterwards it will run on Ubuntu. Unfortunately I get stuck on the black screen after the screen with the white Google text shortly after booting.
How can I get the system running and if there are any problems, how can I reflash Android?
I tried it with an Android tool but it cannot find my device it says something with "no adb".
