Hi there! Because I did not make it right after 2,5 h work (google, my knowledge) I decided to write here. Some person I know decided to upgrade the console trough its settings to the latest firmware which caused in every attempt this error (here 3ds not DSi) :My ds lite runs this R4 card without any problem. 3ds on the other hand runs my acekard. So the problem is that R4 won't run on 3ds ( here you go the picture):What I've done so far: format settings of console as well it soft to fabric installment ( but without any success), format with program->SD cards ( this in R4 and one 2GB in console) - same failure, upgrade R4 card to latest 4.4 ( still got this error above). I'm helpless, please give me some advice of yours, cheers!
