Problem: Nothing happens when I try to power the console on or enter RCM.
Background:
About two months ago I bought a V1 Switch from a friend with the intention to hack it. I did so successfully, and even successfully replaced the connector on the motherboard for the SD card reader when it broke. At one point, my games that I had on both my emuMMC and sysMMC were found to have corrupt data, and I wanted to start over and reinstall everything from a clean slate, so I restored the sysMMC backup I'd made. Turns out, that was a backup from when I had initially gotten the Switch, complete with all my friend's data and an older version of the OS (version 17.0.0, if I remember correctly). I was aware of e-fuses and the issue with burning them due to downgrades, but I wasn't too concerned since I knew that RCM would always work. It wasn't connected to the internet, so it didn't force me to update the system before initializing (factory resetting) it. As soon as it finished, the screen went black like it does normally, but it didn't come back on. I figured it was in RCM, but TegraRCMGUI didn't recognize it. I held the power button for 20 seconds for good measure, put in a paperclip, held volume up and pressed power, and nothing. No RCM. No backlight on the screen. Nothing.
Troubleshooting I've done so far:
As of writing, this happened about a month ago and it hasn't shown any signs of life since. I've since taken it apart and tested it with a multimeter and the pins on the right rail are excellent, ribbon cable on it is fine, etc. The battery, however, was at 2.4 volts, the cutoff voltage for charging the battery. I plugged in the official charger and it immediately began charging. After about 20 minutes it was holding the charge steadily, so the battery does not appear bad. I had also tried keeping the console on the official charger for 2+ days straight and then held the power button for over a minute and tried putting it in RCM and still nothing. I'm at my wits' end. Perhaps someone knows the solution.
