Ok the thing is that i can't use any SD card on my switch, he FW is 5.1 now, it asks for update to use SD card (got 2 128 gb cards atm, one is brand new). So if i update i will get 6.2 fw that means RIP CFW. If i try to start atmoshpere, it not help much too, cause it gives me an error FatFS Error: NOFAT, failed to mount SD card, FatFS error 13. What shall i do now? Any solution? Thank you in advance!
