[2508.4] [rg28xx] Loose Goose stuck on MuOS logo after loading ROMs

[nscreated]

Hello! I see there are a couple of threads about this already with notes that the issue is fixed. However, on my new rg28xx, I appear to be having the same issue with 2508.4. My issue might be different, since the 28xx doesn’t even have WiFi.

I am able to complete the initial setup, and I can shut down and reboot into MuOS. After removing the card and copying a few ROMs directories into the ROMs folder, then safely ejecting the SD card and replacing it into the 28xx, I am stuck at the logo.

I have tried:

• Reflashing (4x)
• Copying the rom folders one a time
• Pressing the reset button

Is there further troubleshooting info I can provide?

Amazing. I wasn’t using a Steam Deck but I am using Bazzite on a GPD handheld. I will disable automount and give it a go.

I wrote a guide on how to disable this for the steam deck - since you’re running bazzite, you might find it applicable!

Using a Steam Deck to transfer files

My Device is Stuck on the Boot Logo Have you inserted your SD1 card into a Steam Deck and when putting it back into your device, it is unable to boot properly? This is a known issue - the Steam Deck is auto mounting your mSD card. This is not something that is caused by muOS, and it isn’t something that a future muOS update could resolve unfortunately. There are multiple partitions on the mSD card and the first one is very important for booting, the Steam Deck attempts to ‘repair’ this by defa…

I can now confirm your guide works on Bazzite as well. Problem solved.
