So I attempted a hard mod the other day. However, when I try to power on the N3DS XL - there's nothing. Battery is plugged in the right way. Tried plugging in the charger. Nothing. Checked for solder splatter, all of that. Took off the mod for now until I can get it working again. I cleaned the board with PCB solvent so there shouldn't be any solder left over. Tested the fuses on the daughter board as well as near the charger port and they still work fine (there's resistance / continuity). There's no led/noise/lights. One time last night when I put in the battery, I heard a quick beep while pressing the power button, but I couldn't replicate it... So I don't know what else is going on. Triple checked all the ribbons and they all fit. However, the mic and the one to the right of it don't fit as snugly. All of those connector types (on the board) feel the same way. I lifted it up at about ~45 degrees but they don't shut tightly anymore. Checked for micotears - but i don't see anything. There may be a tear on the screen ribbon cable, but it should still power on before it enters failsafe mode. Anyone have any ideas? Thanks for all your help and inquiries.
