I basically tore off the top part of the 3DS from the bottom. Is there anyway at all to fix this. It’s split completely off
This will require a replacement shell plus replacement ribbon cables. Honestly the cost investment + the repair difficulty rating (10/10) isn’t worth it, i’d recommend you sell it for spares on eBay and buy a replacement unit.
