Homebrew Problem 2DS: “Unable to mount CTRNAND...”

[Jim12]

Hi everyone, I'm having the well-known CTRNAND problem but I tried all the online guides without solving it. (CTRTrasfer, CTR type D9, TWX, FakeTicket, update all ...)

The problem occurs when starting games for 2DS, instead trying a game for 3DS I know the error: "ErrDisp -> 38"

Please help me
