What was the purpose of downgrading? Did you make a backup first?

Its happened by mistake my brother update it he wasn't know it could damage I fixed it with mode that can updates my switch to the last firmware then downgrade it to 7.0.1 ex fat support also my sd cards damage the sx os folders and files I replaced them with my back up files it's now works great I wasn't know ex fat could damage my files and folders and one extra note Nintendo folder was one of the issue I remove it totally and create a new Nintendo folder to make everything running smoothly now everything is perfect.


Thanks I just want to make sure to write what happened with the solutions it could happen to anyone

Regards

Glad you got it working. Just as an FYI, 8.1 is supported so there was not really a need to downgrade. If you were missing exFAT you can always use ChoijudourNX to reinstall the same FW you are using with exFAT support. Being that you updated officially you should have had exFAT support on 8.1 though.Best to leave downgrading as a last resort and search around first. You can really mess your Switch up if you do not downgrade correctly.

You are totally rights, but what happened to my switch is the sd cards after the update to ver 8.1.0 its damage the files and I thought its not support the last ver when I downgrade and got the restart loop I figured it our its from the sd cards and specially Nintendo folder you should delete it I wasn't know that till I delete the Nintendo folders then I boot the sx os it was not fully working half files was showing only I really confuse with it then I realized its sd cards ex fat could damage the files now I almost fully understand how its works and how to fix most of the switch issue I really was worry about how to fix it lol

Thx alot
