SX OS switch is stuck at the "nintendo switch" screen after a failed retroarch install/update

Sound like sd card issues or some corruption in retroarch files.

 

exfat corruption is bullshit for noobs that dont understand how data works, or the exfat driver.

anyway, your issue is that you have something in an atmosphere folder or switch folder trying to load up. Use a blank card after format, put only the sxos file in it, then send the sxos payload.

dont worry about exfat corruption unless you interrupt a lot of games/apps while they are read/writing.

good luck, it isn't bricked dont worry

 

I agree. Been using exfat since day 1 with zero issues.

1. Copy everything on your SD into a folder on your computer. (This wont touch your emunand).

2. Format sd as exfat.

3. Get latest beta SX os and put on freshly formatted card.

4. Copy just the SX OS license file to the SD card.

5. Put the card back into the switch and see if it will boot into emunand.

6. Get fresh latest copy of retroarch and put files on SD. See if it will boot from emunand.

7. Copy anything else you need from your computer back to SD and test.

 

You should move to FAT32 as exFAT is more corruption prone than FAT32, exFAT is less reliable and robust than compare to NTFS or HFS+ and slower than a native file system. The lack of Journaling and redundant file tables can lead to data loss as well.

 

Wow people... https://gbatemp.net/threads/retroarch-switch.492920/

Using Retroarch with exFat is asking for trouble, whether you're a noob or not. Retroarch is almost constantly reading & writing from files, and I know the key with Homebrew is to always "properly" exit and not use the Home button, especially during writes, but if your console locks up (which is not uncommon, especially if you're playing with settings on some cores) you could be SOL.

Use FAT32. You can still install large NSPs over USB, over the network, or you can use an NSP Splitter. Tinfoil makes it easy if you're using certain "shops." Otherwise, USB installs are great, they save you time because you don't need to copy the NSP to the SD card first. There's really no reason to stick with exFat.

Chances are that your emuMMC is fine, you just need to follow the same directions other people are telling you. Reformat your card, copy over new versions of SX OS, Retroarch, and whatever else you want. But for god's sake, format it as FAT32, not exFat!

And for the record, I used to use exFat, and the only time I saw corruption was after using Retroarch. Screwed up my card pretty bad, even filenames had illegible characters in them. Switched to FAT32 and have never had a problem since.

 

You clearly don't know what you are talking about, exfat is not supported for a good reason.

 

You clearly do not know what you are talking about. Been using exfat since day one, guess what, no corruption. MANY other users can say the same. Fat32 is for noobs.
