Hello:
I´ve got an R4 SDHC Gold Pro 2018 card, which used to work perfectly fine with NDSL, NDSiXL, and ON2DS. I used it to put CFW in the 2DS, which works perfectly. I tried to restore it, and I´m pretty sure (99,99%) I did it all perfectly fine, but now, although it is detected by both the 2DS...
