Canonical Post Instructions for Flashing Ubuntu on a Phone or Tablet
After they have made the best version of the Linux OS for PC and brought it to version 12.10 containing lots of changes and improvements, Canonical are moving along in the mobile world, willing to set a new path that has managed to gather so many fans even before it was actually released.
A short while ago, Canonical promissed to release a Developer Touch Preview for their mobile OS – Ubuntu Phone / Tablet and post instructions on how to get it on devices like the Galaxy Nexus and Nexus 4. As for the tablet version, it can be installed on Nexus tablets such as the Nexus 7 and Nexus 10. Though it´s still some time before a final release, the developer reports that after flashing the most important functions, such as GSM and front and back cameras should work. Installing it will require that you own a Linux based machine and some basic knowledge.
Getting Ubuntu Phone to work on your Nexus device will not be a hard task. It requires installing the dedicated software in Linux by executing the commands you will find on the official page. After that it´s just a matter of connecting the device and flashing it with the dedicated commands. It should be noted that the Nexus device should be unlocked and that Canonical has also posted guides for restoring to Android. You will find all the details by visiting the Ubuntu Wiki official page.
