Hi i have some serious problems. i dont know what is nand and all those things but i will try to tell you whats happend. i had a 3DS xl on 9.2 firmware then i run gateway ultra exploit. and downgrade to 4.2 i followed the guid. i use ds flash card and installed gateway (on my 4.2 3DS) and do what the guide says to install cfw: do things with these programs: Emunand tool and the drag emunand here file. then i installed palantine cfw and installed dev menu. i have some problems: cfw sometimes wont boot. system crash. system dont boot and the biggest problem: all my installed CIA games and the dev menu are gone like i never installed them. i fix this when i delete everything from the SD card,and again put the CfW files in my SD card and istall dev menu again. but its happening again and again!. 3rd time already! Am I doing something Wrong? I read that i cant run CFW on My systemNand and i need to use Emunand? do i Need to do something with it? please tell me how to fix it and why there is only 2GB on my 4GB CARD? is it the EMunand tool cause that?
