I am having a problem that looks suspiciously like that of @shabreen ...
How do you reboot to recovery?
The power button either switches it on or switches it off....
Power button plus volume up sets it in Fastboot mode.
Power button plus volume down gives a menu....

@Gentle-Ent Hi, I haven't been around here for some time and it's a bit late now in september, but if you're still looking for a solution, I've had a similar experience with an OPO a few months ago and this helped me out:

After having restored this factory image on the phone I was able to install UT succesfully with the snap version of the Ubports installer.

@magnolia_dudeFirstly glad your all sorted and enjoy Ubuntu Touch. Windows often throws a spanner in the works unfortunately. Things get lost during the process which is why we say to use the 15 sec adb version on windows and to remove other phone drivers. Why it happens I'm not sure, I never had an issue once I had 15 sec adb installed but others have. Some don't even need the 15 sec version. Which is what makes it awkward when adding or not adding info to the install instructions. Still maybe something to keep in mind.
The snap version of the installer is in my opinion the easiest version to use and you can watch progress in the terminal.

@cembra hi, I've moved this thread to Off topic.

As that model is not in the supported devices list (https://devices.ubuntu-touch.io/) you'd need to port it (http://docs.ubports.com/en/latest/porting/introduction.html).

Someone started this https://github.com/Halium/projectmanagement/issues/115 so maybe you can help them.

@advocatux I tried it now, and the numbers are inconsistent. Now it failed after 71% with general network failure. I have to try to download the click package on notebook. Thanks for information, that you can download the package.

@tsunamiuu is the 2012 grouper ? Did you have any luck ?

@advocatux said in UBports installer under ubuntu 16.04 desktop:

First time I read this /hdd/home/sebastian/ it got my attention too. How is your /home mounted exactly?

Ah yes. This could be. Have to check with my Admin. Thanks.
