Wow that 'escalated' quickly Yes I can confirm that UbuntuTouch can be installed on a FP4 Possible with the good documentation/steps and tooling. I installed it with ubports-installer_0.11.2_linux_x86_64_AppImage via my Manjaro NUC box. The installation went smooth! I experienced the unlocking process as a little sweating, because the phone boots several time. And each time you have to go to the intial 'start' screen and enable the USB Debugging again. Now I should spend some time in discovering UT. I've chosen for the 20.04/stable release at first.

@jilly aha, that sounds great, I've the 6/128Gb model. Thanks for your reply!

@Opolork thank you

Greetings from The Netherlands,
My name is Jan and I like the idea to have fun with a Linux based mobile OS. Certainly with the current developments in the (tech) world. A couple of months ago I started actively to de-google. When I reduced the amount of apps the switch to another android 'taste' would be easier. I bought a Nothing CMF 1 and installed e/os. I host my own nextcloud instance, and this combination works like a charm. I already work with linux boxes for a long time. When I read more about UbuntuTouch and PostmarketOS, I liked the idea to buy an FairPhone4, and do the 'next step'
Cheers, Jan

Hi experts !

Here a newbie question. I just received a FP4 with Android 12 out of the box. As I understand the page https://devices.ubuntu-touch.io/device/fp4/ it should be possible to install UT on the FP4. I should first downgrade to A11. But when I follow the described steps it should be possible? Asking because I see some posts when people get stuck in the boot process. I succeeded before to install e/os on my Nothing CMF 1, I do my private stuff on a Manjaro box, so I do hope to have a lot of fun with the FP4 with UbuntuTouch or PostmarketOS or ....

Thanks in advance for a reply.

Cheers, Jan
