Update sx os or atmoshpere to the latest version

I did, atmosphere boots up but doesn't show anything after that
I guess i missclicked and choosed FAT32 instead of EXFAT :/
what should I do ?

If that is the case, just make a backup of your SD card on your computer. Then format your SD as fat32 and put only atmosphere files and choidujour with the switch update

If it works and you want to keep fat32 you can transferr all your files (but i think you are gonna to reinstall the 4GB+ games). If you want exfat instead, update using choidujour again and this time make sure you choose exfat. After that format your SD again to exfat and copy all over again your files

If you have a second SD, just use that instead of the one you have on your switch, so you dont need to copy your files to your computer and then to the SD card again

That's what I exactly did, I looked for an old 32gb card on fat32 , the switch booted up and I installed the exfat version this time, And It worked! thank you so much for help
