Struggling to get SteamOS onto an ROG Xbox Ally X

[Remixed-Witch]

Here is what I have tried:

On bios 316
steamdeck-repair-beta-20260413.100-3.8.2.img - Fails to get to get to the live desktop [Video below]
steamdeck-repair-main-20251027.1000-3.8.0.img - Installs up until the first reboot, then boot loops forever
steamdeck-repair-beta-20260327.100-3.8.1.img - Fails to get to get to the live desktop
steamdeck-oobe-repair-main-20251027.1100-3.8.0.img - Installs up until the first reboot, then boot loops forever

On bios 317
steamdeck-repair-beta-20260413.100-3.8.2.img - Fails to get to get to the live desktop [Video below]

On bios 313
steamdeck-repair-beta-20260413.100-3.8.2.img - Fails to get to get to the live desktop [Video below]
steamdeck-repair-main-20251027.1000-3.8.0.img - Installs up until the first reboot, then boot loops forever

During this, I have changed both the physical bootable USBs and the internally SSD.

Hi, I took a look on my ROG Xbox Ally X running BIOS 317 and I was able to boot into steamdeck-repair-beta-20260413.100-3.8.2.img with a known good external drive. Are you sure nothing went wrong with flashing the repair image to your drive(s)? How specifically did you flash it?

I used both Rufus and balena etcher with no difference between the two.

I have similar issues and cannot figure out what is causing them.

Same issue on this end, the only version that's booting is the 3.8.0 repair image, however that doesn't have support for the controller and the like, the moment you update you end up bootlooping and that's on any release, Beta, Preview, Preview RC, Main etc.

Same image boots up just fine on a Legion Go 2 so there seems to be some issue somewhere from the XAX side, the only thing I can really think of that's different off the top of my head is that the XAX has the AI variant of the Z2E chip
