Hello everyone,

I recently got my hands on this R4 flashcart (photos attached) but I’m having a rough time getting it to work or do anything. I've tried testing it on both my DS phat and O3DS and here is what's happening:

• On my DS Phat, the console gets stuck on the boot screen (BIOS screen) even when there is no SD card inserted
• On my 3DS, the cart is not detected and shows no icon at all in the home menu

What I've tried so far:

• Booting the DS Phat with and without the µSD card (same freeze either way)
• Cleaning the gold contacts on the back of the R4 cart with rubbing alcohol and a Q tip
• Formatting the µSD to FAT32 and 32Kb cluster (but since it freezes without the card anyway, I don't think it's an SD issue)

Does anyone know what I need to do to configure this cart properly, or if it looks like the cart is faulty/incompatible? Any help would be appreciated.

Update: I actually managed to fix it. I used ntrboot on the modded 3DS to restore the flashcart's original firmware and it works perfectly on both systems now
