Use TegraRCM Gui, install the driver in the settings menu.
Power down switch hold power button 20 secs..
Put the console into rcm mode. via a rcm jig or other rcm method.
Once you belive you are in rcm, plug in the cable from pc to the switch and send the payload.
Id start with lockpickRCM or biskeydump
Get ya console specific key.,
then use hekate payload and backup nand.
The switch is already well on it's way back. Like I said, I can detect my patched switch just fine, but this one can't be detected on any one of my 3 PCs, and 5 different cables. It took me all of a minute to get my patched unit in RCM and detected, but 6 hours of playing with this one and nothing.
On what you said, I couldn't do any of that anyways, because the PC won't detect it at all. Drivers, no drivers, it won't even show up as unknown device or APX. It'll charge, that's about it. I clearly get it into RCM, plug it in, nothing at all. Yet I switched to patched, detected fine in less than a minute. Clearly even though it charges, something's wrong with it. Either the USB port was damaged in a way that just didn't affect the pins used in charging, or something else along those lines.
