Sorry, forgot to note that I am talking about Nexus 7 2012 (grouper).

> I tried to flash Nexus 7 as described, but can't get Mir to work. After final reboot the display constantly turns on and off. The following lines are constantly appearing in /var/log/messages during this:
> Jan 25 10:26:08 ubuntu-phablet kernel: [   73.848462] init: sys_prop: permission denied uid:32011  name:persist.sys.NV_DISPXRES

> Jan 25 10:26:08 ubuntu-phablet kernel: [   73.977776] iio-buffer, current state requested again
> With Mir disabled the shell works, but there are random freezes/reboots.

>> Flashing 4.4.2 based Ubuntu touch images:
>>
>> 1) Flash the original 4.4.2 based Android image from
>> https://developers.google.com/android/nexus/images ($ sudo
>> ./flash-all.sh) - needed to make sure you're using the right
>> bootloader and radio fw
>> 2) Unlock your bootloader: $ fastboot oem unlock
>> 3) Boot the device with the original 4.4.2 image and reboot to bootloader
>> 4) At the bootloader, flash boot, recovery and system for your device
>> (http://people.canonical.com/~rsalveti/aosp/<device>)
>>   - fastboot flash boot boot.img
>>   - fastboot flash recovery recovery.img
>>   - fastboot flash system system.img
>> 5) Boot into recovery and flash Ubuntu using
>> http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/pending/trusty-preinstalled-touch-armhf.zip
>> (adb push <zip> /sdcard, then flash via menu, or use sideload).
>> 6) Reboot, and use phablet-network (from your host) to setup the network
>> 7) Enable my personal PPA (latest MIR): sudo apt-add-repository ppa:rsalveti/ppa
>> 8) Install latest MIR packages: apt-get update; apt-get dist-upgrade
>> 9) Enable MIR: $ touch /home/phablet/.display-mir
>> 11) Reboot and profit!
>>
>> Please let me know if you have any issues, and also let me know about
>> possible new bugs that might happen with this new image.
>>
>> Here's what I built and tested:
>> - grouper (not officially supported): working as before, not many changes
>> - mako (officially supported): working as before
>> - flo (officially supported): shell rotation is not yet implemented,
>> and side stage is not fully functional
>> - hammerhead (not officially supported): couldn't test, don't have a device
>> - manta (still officially supported): better and faster
>>
>> Video playback is the only feature that's known to be broken, and we
>> should hopefully get this fixed next monday.
>>
>> Working now to enable the x86 and ARM emulator targets.
