TL;DR - Use the Sthetix Level 2 Restore Guide (New Method)
This should theoretically work for any switch with this error, but I can only confirm that it worked on an OLED.
I picked up an OLED recently that had error 2002-4315 on boot. I couldn't get the console to display anything else, and I couldn't enter maintenance mode to try a system reset. I did a good amount of research and found that this error typically means a corrupted eMMC, but I couldn't find any forum posts, videos, etc. that had an actual fix for the problem. This took quite a while, but eventually I managed to get the switch working again.
I started by modchipping the system so I could modify/restore the file system(s) on the device (Note - A modchip will be required for this, unless you have an unpatched V1. You need access to Hekate for this fix). Initially I tried fixing the eMMC with EmmcHaccGen and the SystemRestoreV3 script, but it still booted straight to 2002-4315. I then tried to create an emuMMC just to see what would happen, and I got the same result. I then tried Sthetix's level 1 restore guide, which was basically the same but used NxNandManager instead of the SystemRestoreV3 script. I had no luck there either, it was still booting straight to the 2002-4315 error. I again tried an emuMMC just for fun--if I could get that working that would be enough for me--but still no luck.
I then proceeded to the Sthetix Level 2 restore guide, with pretty low hopes. At this point I figured the eMMC was probably dead and would need to be swapped - something I can do, but didn't want to unless I exhausted other options first. It took quite a while, but after all the steps--to my surprise--the switch booted into OFW!
I got the red Nintendo screen, then the setup screen, and let out a big sigh of relief. So for anyone experiencing the same issue, or anything similar, give Sthetix's Level 2 Restore Guide (New Method) a shot, and it should fix your issue!
Not a very interesting post, but since I couldn't find any solid fix info anywhere on this I wanted to make a post to document it. That way if anyone comes across this problem in the future they don't have to waste hours like I did trying various things. Anyway, see you all around
