Hi guys, i have a very strange issue. I buy this card 10 days ago.. all work fine with 4.11 firmware, time by time the ds freeze at startup, with "Nint" write on the upper screen and so stuck all. I have try to refresh firmware, pull out micro sd, format nand memory with different fat system, nothing... Maybe is hardware of my acekard? I have try to clean contact at bottom... the same.. Now it work very rarely 3/10... 30 %... i have no problem with my r4...and surely original cartridge.... Someone have similar issue? SOMEONE CAN HELP ME? :-)) bye!
