here is my custom build e-2.9-s for Gigaset GX290:
Install instructions:
Warning, you are doing this on your own risk:
If you are switching from original rom, you must do a factory reset,
that is delete and format the userdata partition!
make sure the battery is charged!
Unlock bootloader in the deleoper options
(tab five times “about phone/build-number”)
(system/developer: unlock bootloader)
reboot to fastboot:
(hold volume-up, select fastboot with volume-up, start with volume-down)
unlock, confirm on screen: fastboot flashing unlock
in recovery,
Do a factory reset if switching from original rom!
select “Apply update”, “Apply from adb” adb sideload e-2.9-s-20250531-UNOFFICIAL-GX290.zip
reboot.
This build got these enhancements:
Kernel weed out
The original Kernel was build with debugging enabled in all parts.
Here is a greeting from the old kernel:

Yes, this is how that device was sold.
I cut off a lot of debugging cruft. A lot. A lot.
fixed charge mode
The battery animation now works.
And there was a bug that the device did not turn off the display backlight. So it doesn’t do fast charge. I fixed that.
wireless charger
My device used to become punk after using a wireless charger. I fixed that somehow: The original code is crap. I’d like having the data sheets.
Android
fixed adb via wlan
Bug was, it did not remember the wireless network.
/e/os
I included Trebuchet launcher. You get the choice at the end of the welcome.
F-Droid with privileged extensions
bugs?
So far it’s just “App Lounge” that does not work for me. Let’s see if that gets fixed in e-3.0
Thank you, for your contribution on this device that was hoped for a long time.
.
When i build /e/, i like to share also the recovery-e aside the main .zip file, (and the others mandatory .img to flash prior when exist).
i take it from /out/target/product and rename it following the /e/ naming convention (copy/paste from the main .zip filename).
Edit : reading your instructions, i just see you included the recovery into the main .zip
@piero : I am sorry but I don’t get the point of your reply.
Gigaset brand is not referenced in your first link. ADB request to already have the phone. And even if I known the code name of the GX290 and the GX290 plus, I didn’t find any list of compatible code name, neither in this topic nor in the sourceforge link.
So, your reply sound like a “search better before asking”. I could understand if your link would contain any helpful information. But here, if there it contains an answer to my question I didn’t find where, and I feel a little like talking with these bots which always give predefined answer whatever the question is, when you try to contact your phone operator.
It seems that the only difference between the two models is the quantity of ram and memory space. I don’t see any reason why they would need a different build, but I would have the confirmation before buying one. Will this build work with the “plus” model ?
i wanted to know the device codename to search XDA…
.
also, unlike some other Gigaset “Plus” device, the GX290_plus is not registred in the list of Android Supported devices - Google Play Help - Google Support (this list is not always accurate, there are some duplicate and some ommited devices)
Why i asked for device productname…
But the reason you asked the question is that you still wanted some certainly after you had done your research. @piero has spent much time demonstating why there might be uncertainty !
You said
Gigaset brand is not referenced in your first link.
This is because you were reading what the forum creators call a “preview” – unhelpful in this case. If you care please just read the link (briefly) [HOWTO] Find device codename … there it is demonstrated that there are many ways to find the device codename and you can then check your device is an exact match with the build. Is why you asked your original question.
