Hardware Scratched NS Mobo, showing no signs of life

[Roswell]

A few days ago I'd went to readjust the LCD in my switch as it was a bit crooked under the digitizer. I ended up prying back the digitizer too much and took the cable out of the motherboard. So, I decided to take my Switch apart and reseat the digitizer. Instead of just taking out the piece responsible for the touch and headphones and such, i took out the entire board, and one part of this included unscrewing the heatsink. I'd done this many times before what with swapping thermal paste and installing the SX core modchip, but the screws were stripped. I tried prying the metal things to break them so I could take them out with force, to no avail; I ended up using a drill and drilling the screws to break them. However, what I noticed after all was said and done was that my Switch was not working anymore, be it in docked mode or handheld. The fan would not spin, there was utterly no sign of life. What I found was that some traces appear to have been cut up on the board, and following them with my eye it seems they are responsible for handling the NAND, though I'm not sure. The SX Core chip lights up green to signal it's working properly, but nothing else happens. Any help? Thank you for your time!

If picture 2 is anything to go by, you’ve definitely grounded some test points - the pad around the screw is connected to ground. Clear that area up, but to be honest, it looks kinda butchered - the ribbon doesn’t seem installed particularly well either. You’ll need a multimeter to figure things out, but this is a multilayered PCB, so those deep scratches in the PCB could be affecting traces you can’t even see. Uhm... good luck.
