first off switch boots directly to blue screen no nintendo screen. I tried connecting this to tegra rcm and it recognized it but when booted it is just a black screen. This is a hackable version switch could a kid have just hacked this and removed some critical software? if not how do you guys usually check if a cpu/gpu or something needs a reball with a multimeter or do you just try to reflow?
Try this: look up
Sthetix unbricking the nintendo switch by rebuilding the NAND
There should be his website
Follow his guide
If it doesn’t work try again
If this doesn’t work, it’s a hardware issue, most commonly the charge chip
