So i've made 2 threads that are long gone by now on how my 3ds wouldnt turn on after a breaking a screen and repairing it. My verdict in the end was to buy a completely new 3ds and swap the motherboards. Well, even after i bought a new 3ds, and put my old motherboard in it, it still won't turn on. The ribbon cable looks fine, i have no idea what could be causing this. I'm looking for 1 of 2 solutions: 1: Is this an issue that can be fixed? Is there something im missing? Or is my motherboard with my many mods gone forever? 2: if it cannot be repaired, i have multiple nand and sd backups. Is there any type of save manager that can salvage the saves from my sd card? Or a way to get anything back from a nand backup on a different 3ds? Thanks for hearing out my issue, and hopefully there is some sort of a way we can fix this.
