My switch has starting to behave strange. After update to sx os 2.0 and creating emunand my switch go crazy. After couple of minutes I got error message with 12 sec to power off. So I deleted emunand, make a factory reset and now I have empty icons in horizon main menu. I can't delete it and do nothing. I try go to recovery menu a do factory reset from there but still empty icons remains. Now I dont have any problems with auto error screen after couple of minutes but when I put any nsp file in root of sdcard or in switch/nsp and go into galery then boom I got error screen again with number 2168-0002. After many tries I finally install zelda. I checked sd card many times in windows for erros and windows shows that there are no erros. I exchange sd card to another. Change to sx os 1.8 and 1.9 but no luck. Nothing helps. Of course I don't have nand backup. Nothing helps. Any sugestion?
