I have exactly the same problem with a Nexus 7 ('grouper').

I don't update regularly : IIRC, I did the last update ~2 weeks ago and 
it was ok. Then I powered it off. When I started it monday or tuesday, 
it was stuck on "Google" black screen.

always : since it appeared, it can't boot normally

I already performed some tests :
in recovery mode, i started some variations of phablet-flash :

phablet-flash cdimage-legacy -b -d grouper
phablet-flash cdimage-legacy -d grouper
phablet-flash cdimage-touch -b -d grouper
phablet-flash cdimage-touch -d grouper
phablet-flash ubuntu-system
phablet-flash ubuntu-system -d grouper

but the problem is still there.

I tested also some manual copy with adb push :
sometimes the copy is ok, some times there is the error.

the command :
$ adb push 
/home/michel/Téléchargements/phablet-flash/ubuntu-touch/20130828.1/saucy-preinstalled-touch-armhf.zip 
/sdcard/autodeploy.zip

returns :
failed to copy 
'/home/michel/Téléchargements/phablet-flash/ubuntu-touch/20130828.1/saucy-preinstalled-touch-armhf.zip' 
to '/sdcard/autodeploy.zip': Read-only file system

What is surprising is that the error comes after the copy is complete : 
I have to wait ~5 minutes before seeing the error message.
If it's really a readonly error, I guess the error should appear 
immediately.


Then I execute :
$ adb push 
/home/michel/Téléchargements/phablet-flash/ubuntu-touch/20130828.1/saucy-preinstalled-touch-armhf.zip 
/sdcard

and it returns no error :
1333 KB/s (374128349 bytes in 274.068s)

so i execute :

$ adb shell
# cd /sdcard
# mv saucy-preinstalled-touch-armhf.zip autodeploy.zip
# reboot recovery


then the Nexus reboots and starts the update process (bugdroid with a 
rotating wireframe star) just for few seconds (3-5) and then goes back 
to the black Google screen forever.


If you need other tests, I can follow the exact informations for a 
manual installation 
(https://wiki.ubuntu.com/Touch/Install#Manual_Download_.26_Installation)

Hope this helps.
