I think you are asking the wrong question. These questions are rather simple to answer (once) or link to a duplicate.
The tricky part may be certain specific devices, in these cases the answer should be that the device is (obviously) not supported by Ubuntu Phone/Touch and therefore not here.
From the Android Enthusiasts perspective I wouldn't want the question there, because I wouldn't know what the Ubuntu Tools did to the device (like installing a custom recovery image).
If possible, treat it like a blank device where you want to install a certain operating system.
- Officially supported Ubuntu Phone devices
- Answer here, link to duplicate or instructions on the Wiki.
- Not supported devices:
- Answer with link to generic guide that gives instructions how to reflash (non-locked) Android devices and a comment that the device is not supported on Ubuntu.
- Where can I find stock or custom ROMs for my Android device?Where can I find stock or custom ROMs for my Android device? would possibly be a good starting point.
And possibly link all duplicates to these two questions.
