As this is really a very old post and it has been made clear that installing UT on Gigaset devices is not supported I will lock this thread.

If you feel the topic needs further discussion please strat a new thread.

I just found a suggested install routine for the Gigaset GS4 using Lumo AI from Proton.

I’m not sure if I will do this, because I am new to all of this.

This was the final summary:
8. Summary

Unlock bootloader (Fastboot mode, fastboot oem unlock).

Get port image (community repo on GitHub).

Flashing by fastboot (fastboot flash ...).

Restart device and set up Ubuntu Touch.

If you encounter difficulties during a step, first look at the UBports forum for similar problems - there are usually current work-arounds from other GS4 users.

Good luck installing Ubuntu Touch on your Gigaset GS4!

There have been many discussions on here about that. Some have got UT running on Gigaset devices but you need to be careful.

GS4 is definitely unsupported by UBports.

The Gigaset GS290 doesn't have the same digital signature as the Volla Phone

And this is Gigaset GS4, which is probably not identical to the Gigaset GS290.

Maybe try installing /e/OS to get it working again:

I doubt Ubuntu Touch would be easy to install on it.
Some people have managed to do this by modifying lines of code in the root of the device, but that's beyond my skills...
