    As you can see, ive soldered the common points for rcmx86, including under nand, yes not the best job, but regardless this doesnt turn on or show anything on screen and I have no idea why, any ideas, or stuff I should try let me know

    Some closer higher res images of the common pads, under emmc nand the 2 points seem to be a perfect job but if needed I can capture that too.

    I gues on earth.
    Do you have autorcm? What is your fuse count? Was it working properly with the modchip? Why did you remove it? What actually happened?

    Did you unplug battery before soldering?

    Autorcm no, Fuse count last I checked was 7 or 8, 8 i think, It was but remember I was having joycon issues, I removed it to make the wires smaller as they were extremely long and to do a better solder on them in general.
    I have no idea what caused it to stop working, though the last time I did something before the issues arrised was I was messing around with a multimeter to check if gnd near power was sending to stuff on D+/D- and to check if D+/D- was sending to the RCMX86 (which they all were).

    If you removed ribbon cable next to joycon then reseat it - It doesn't look all the way in. This cable will stop switch from posting.

    Well there is your issue, you need to unplug battery when soldering, probably a damaged board now.

    If I plug it into my PC it shows up as a malformed USB configuration device, so its fairly odd

    I added higher res pics of some areas, perhaps may help

    Just checked mine and yours looks a bit out - That is most likely your issue. Push clip up and try pushing in with tweezers one side at a time and see if it goes in more. I had a brand new switch in that was sensitive there.

    K what power point did you use>? If you got any flux on that ribbon cable clean it as best as possible.

    This is also my guess, it looks like a solder bridge.
