Hi! Today, my brother was using his DSTT, doing some GBA backups and playing games. Suddenly DS won't recognize it anymore. I've tried to clean all metal contacts, reflowing solder, etc. with no avail. I've also tried fake recovery software, and it says "Not Support Device" with different error code every time I try it. Interestingly my Action replay DSi recognizes it, but when I try to launch it that way DS's screen shows DSTT's "Loading" screen for a one second and then only white. Is there any way to revive it, or should I just buy a new flashcart? That DSTT is years old (bought around 2008-2009 from DX), so I wouldn't be surprised if the cart was already dying.
