I have this flashcart, R4iTT (the one with the new sticker) (since this is the only one available in my area without actually shipping) and it has been working great but yesterday it has crashed (hang at loading a game) and then when I restarted my 3ds, it shows "An error found, power off etc.". I tried the flashcart on my DSLite and it only shows a white screen. I really need your help guys! Is there some way to recover or reflash my flashcart so that it would work again? I tried the one with DSTT but it says invalid card. Thanks in advance!
