Gigaset GS290 Boot Loop

[jocmoc]

Just bought a brand new GS290. It was on Stock Android 9. I did the following:

• enabled developer settings
• enable USB Debugging + OEM Unlock
• Updated OTA to Android 10
  Then I booted via adb to fastboot and flashed following the official guide.
  All went without errors.

After reboot the phone does only a boot loop and is in “orange” state. I can go to fastboot holding the volume up key and select fastboot from the menu BUT I cant boot to OS nore access recovery.

I reflashed in fastboot state every version of /e/ but all with the same result.
The easy installer does not connect to the phone, but I can flash with fastboot from a linux machine.

Please help rescuing the phone or find out what caused the problem.
Thanks!

Hi @jocmoc welcome. Have you made any progress? You will have read on this forum of many in a similar position with GS290.

Did you consider the rescue outlined here?

Gigaset GS290, how to root and install ZIP files?

@chrisphl, thank you for your reply! There are many with semi-bricked GS290 who then appear to brick them by using SP flashtool! I would very much like to see how we could assist some GS290 owners by writing a recovery solution, perhaps with TWRP? Post script edit. What follows is a small walkthrough of a suggested method of rescue for GS290. Although this thread is originally titled “how to root and install ZIP files” the proposed rescue method which follows does not use use or expect root. …

Hello,
I have the same issue with an GIGASET GX290 (not: GS290).
As I had perceived by checking the forum and older post, Sylvain, @smu44, might have been able to help on this possibly?
If someone should be able to help on the boot loop, I would be very thankful for advice or help.
thx

Sorry, I don’t do Gigasets anymore
General guidelines here Install /e/ on Gigaset GS290 failed "unlock operation is not allowed" - #40 by smu44 but it’s doubtful that oldies will still work…

/e/OS-Q GSI and the current LineageOS 19.1 GSI + 20.0 GSI by AndyYan work well and are definitely better than the Gigaset Stock Android™10. And should /e/OS-T GSI be released at some point, there is still a chance of keeping the GX290 alive.

Gigaset GX290 also works with Ubuntu Touch (Linux).

awride, merci Sirs.
Hope I can report here on the results soon.
I bought the phone for installing UT.

The Bootloader is opened (possibly with the older adk 30 as far as I remember).

Will first install Lineage GSI or /e/ OS GSI and then UT.

First things first:
I am in Fastboot mode.
But adb devices seems to not find device (before my WIN PC had found it).
Will still try and get the Lineage 20.0 GSI (by andyyan) or /e/ OS GSI and flash via SP Flash tool for MTK- CPUs.

Regarding the OS that I will install first / as a “meta- OS” so aft5erw2rds I can install UT:

Question #1 pls: which Lineage- GSI- Image shall I choose pls? there are two versions (plus signed versions):

1. bvS- Version:

[/lineage-19.x/lineage-19.1-20241019-UNOFFICIAL-arm64_bvS.img.gz]

and

2. bvN- Version:

[/lineage-19.x/lineage-19.1-20241019-UNOFFICIAL-arm64_bvN.img.gz]

Question # 2 (regarding download of the /e/ OS GSI Version:

is my device (GIGASET GX 290 plus) a “System as root” ?

Q # 3

Will I have to Remove dm verity before flashing th Custom ROM pls? I use the SP flash tool from/ for MTK- CPUs.
as by today, it has a bootloop but no custom ROM - it’s got the official GIGASET stock ROM.

Sorry, but I don’t understand everything you have articulated.

The very first condition for the success of your project is a functioning stock Android - without bootloop.

Edit:

+++++++++++++++++++++++ tl; dr +++++++++++++++++++
I mastered the “SIEMENS” GIGASET GX290+ and successfully installed UBUNTU TOUCH 20.4 LTS with UBports tool (choose “Volla x”) +++++++++++++++++++++

old version of the post:

I restored the stock Android on my GIGASET GX290+ (Android V10, as I couldn’t find a stock ROM for Android V9). Now, I plan to try flashing UBUNTU Touch on my device. It’s recommended to use the UBports Installer app for safety, so I selected the Volla Phone X from the list of supported Volla devices. According to older documentation, the SIEMENS Gigaset GX290 was supported, though it is no longer listed in the UBporst falshing tool. From what I know, the GIGASET Volla X shares the same hardware specifications as the GIGASET GX290+.

With that in mind, I’ll attempt to flash Ubuntu Touch using the UBports Installer? What do you think is the best way to do this, Xxpsilon? Have you tried using the UBports Installer, or do you prefer flashing Ubuntu Touch using tools like the MTK SP-Flasher? Which method would you choose?
