If you’ve been itching to try out what Ubuntu has been cooking in the mobile department, today may be the day. Canonical has released developer preview builds of Ubuntu Touch for the Nexus 4, Nexus 7, Nexus 10, and Galaxy Nexus. You may be excited to just start flashing, but let’s go over the risks and what you’ll be getting.
First of all, this requires that you unlock your device. It also wipes it, so you might lose all data if you don’t back it all up to your PC. And of course, flashing can be dangerous. And don’t forget, this is a developer preview: stuff won’t work, there will be bugs, and things probably will go wrong. In fact, here’s a bug on the Nexus 4: “In rare circumstances, the Nexus 4 may get into a state where it may not boot at all after the battery is drained ( even into recovery ). If this happens, the only way to restore it is to disassemble the back of the phone and unplug/plug the battery connector.” Not pretty, so don’t go attempting this unless you’re down with fixing it.
If you are still willing to flash, then hit the source link for all the instructions! And remember to keep a system image lying around for when you want to go back to stock Android. Tell us how it goes!
