Hi guys so i got myself a 3ds (not the n3ds) and find myself that its a Custom Firmware 3Ds. Any ideas to get it back to Original Firmware? Cause I can't access online on almost anything especially my eshop. Already check all of the things inside the SD card and without the SD card my ds won't turn on, the blue light indicator just turn on and slowly faded off. The SD card got those A9LH, FBI, CIA, arm9loaderhax, etc. which i find very confusing! Any kind of help will do.. P.s: I have no idea what are those files and data do, not even a slightest..
