Hello everyone,

I've managed to make a build that boots with the latest versions of ubuntu touch and I wanted to share it with you because I've also been following this thread eager to install ubuntu touch on my phone, although the method to install still might be complicated for some at the moment.

So first off you need to be using Linux, as I don't think project rootstock works on Windows

To install it you must follow the instructions I found here which are, in a terminal:


sudo apt-get install android-tools-fsutils qemu-user-static bzr
bzr branch lproject-rootstock-ng
cd project-rootstock-ng

then to get the rootfs with the mir fixes


./rootstock-touch -p pps:rsalveti/ppa

which takes a little while or you can download the tar.gz from here
but once the screen turns off it takes a while or a reboot to get it back on

Once that part is finished download all the files at the end of the post and put them in the project-roostock-ng directory to make things easier

then in the same terminal with your device connected to bootloader:

sudo fastboot flash boot ./boot.img
sudo fastboot flash recovery ./recovery.img

Reboot your device to recovery and do a full wipe, once that's done, with your device still connected to usb, in the same terminal type:


./rootsotck-touch-installer ./out-XXXXXXXX/ubuntu-touch.rootfs-armhf.tar.gz ./system.img

your device should reboot on its own, once you get to the black screen type:

adb shell
mount /dev/loop0 -o remount,rw
adb push 70-m7ul.rules /usr/lib/lxc-android-config
adb push m7ul.conf /etc/ubuntu-touch-session.d
adb reboot

and your device should load the ubuntu lockscreen

Here are the files for m7ul:

for m7spr (not tested):
and download the 70-m7ul.rules and m7ul.conf but replace m7ul with m7spr

What works:
Wifi (tested only on at&t version)
Audio (I've managed to get audio to work if the headphones are plugged in but not all the way, you really gotta find the sweet spot so it's not really useable yet but it's still progress.)

What doesn't work:

it should run more smooth and the phone should get less hot

Backup file -

I also found a way to have the same kind of dual boot setup canonical made for the nexus 4 by flashing the boot.img (the newer one can be found here on the recovery partition and keeping the internal rom's boot on the boot partition, so in theory if you flash a rom without wiping after flashing the backup and you flash the boot.img I provided on the recovery partition it should also work and then to get ubuntu you reboot in recovery and to get android you just boot normally, the problem is you lose your recovery temporarily and you have to reflash it if you want to use it until canonical finds a different way or I manage to get it to work with multirom.
