Hello, i recently bought a Old3DS XL that boots to a black screen. I've opened it up tried to replace the wifi card to no success, removed the motherboard and reínstalled all the ribbon cables, no signs of water damage or short-circuits, but i did notice a screw was missing and some of them were stripped. The only sign of life is the blue light when i turn it on and the fact that if you try to flash ntrboot it loads the Safeb9sinstaller does half the checks and then shuts down. This also happens if you replace the boot.firm with godmode9 or luma. I believe this could be a problem with the software or NAND but have no way to confirm this. Anyone that could figure this out?
