My 16GB SD is messed up. It has plenty of games, and stopped working when i got the 3DS from the bag, after i didn't used it for 2 weeks. It doesn't show anything [in the SD] in home menu, as it's corrupted. Put it in my Windows 10 computer so i could use chkdsk in it [in a cmd prompt] but nothing, it freezes the computer. I think i can redownload the games in eshop after i get new SD, but the problem is eshop requires i update my fw and i'm in 10.3. O3DS XL. I don't have CFW, emunand or anything, just installed menuhax to have access to homebrews. Will update kill my entrypoint? What can i do? If possible, don't tell me about emunands, CFW and such, i definatelly don't want to pirate or nothing.
