So after a few months of not being charged at all, due to holding off on a digitizer repair (touch screen is mostly okay, just a small section doesn't respond to touch), I decided to charge my Switch back up. First thing I noticed was that the WiFi wasn't connected, so I tried to connect, wouldn't connect. Checked everything, kept getting error code 2110 1100, so cleared settings and set up the WiFi connection manually. Still didn't work. :s
Decided to set that to the side, so I rebooted back into stock to play some Skywalker Saga, and I found that I had to update the system to play the game. Thought that was weird, since I thought I had to be online for that, so I hit okay to see what would happen, and I guess it was a cart update? Because it didn't show up when I said no, but did when I hit update, so my Switch is on FW 13.2.0 now. A few hours later, I wanted to try again with the WiFi, figuring I could try to do something in Hekate. Not sure what my reasoning was behind that, but yeah.
Couldn't get into RCM. Okay, just gotta update the payloads and such on my RCM loader, right? I updated to the very latest payloads, and... well, I still couldn't get into RCM. I Googled it and it seems that the likely culprit is that something wore out on the rail, but I'm not sure if they mean the rail on the tablet that the JoyCons go into or the rails on the JoyCons themselves, because my JoyCons still charge and work just fine.
