Hacking Hardware An issue with error 2002-4315

[Reickun]

extra notes: its on program(might have missed some zeroes) 0100000000000024
i was on a break for few weeks and my switch just stayed on the dock for like 1-2 weeks, it was working perfectly fine last time i used (had downloaded persona 5), but after the break, i picked up my switch and bam, just had this issue. i tried updating,partitioning AND resetting my switch. still sd card stays the same, probably its on read only but is there any fixes that you guys could recommend? there is still some time till i pick up a new sd card, so im open to try anything

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...

Reickun,
Did you find anything? Ive been trying to figure this error out on my oled now for a month in and off. My CFW is at 20.5.0, atmosphere is 1.10 with the last hats pack from the end of December 2025. Everything worked great, until it didnt. OFW boots fine, Sysmmc cfwb boot option also boots fine, but my go-to emunand CFW boot option gives me the dreaded "ERROR CODE: 2002-4315"(fat32 1TB partition, lexar brand. With no format, read or write errors noted in hekate or issues running the benchmark).

Ive tried deleting the Atmosphere, Bootloader, and config folders then paste in a new hats pack without success. Even tried the latest thestix pack with atmosphere 1.11.x thats a few days old. Im guessing it could have been my overclocking since thats the last thing I had been working on seeing if i could squeeze anything more out of my system or not before the error popped up likely corrupting something. But im stumped. Ive seen posts suggesting thestix level 2 nandfix pro guide, but it sounds like its to fix a corrupt physical nand, not a corrupt emunand partition on an sdcard. Id hate to get the system banned if i messed with the stock nand and would rather avoid anything with that. Lets compare notes! thanks, take it easy!

Have you tried running HTestW2 once?
Have you tried running Atmosphere without the overlays and system modules?

Im going to run hwtest this evening on my pc to make sure. I did rename the switch directory to get the sysmodules out of the picure and nothing. Im stumped. I even tried the Archive Bit fix in hekate.

yeah, my sd card was on read-only. tried every way to format and reset it, it always stayed the same. It was possible the cause of lack of memory space on the sd card, and might have heated a bit whilst it was on dock lead to corruption. Basically sd card itself was the problem as it was an adata sd card used for a long time, changing it fixed the whole thing.

Update on my case for any other 2002-4315 error seers. I tried everything and gave up and just wiped the emunand partition and started over. It looks like the culprit was very likey overclocking, as thats the last thing I tinkered with before it gave out on me out of nowhere. I learned my save game database was missing, and I tried a maintenance rebuild through hekate of my emunand (press and hold: vol + & - , and tap your Emunand boot icon option. Dont release the volume buttons until you get to the white maintenance screen. You'll know your in your Emunand by the HOS fw listed e.g. fw20.5.0ams1.11.1 or so). It gave me an option and a final Chance to save my save game files before finally just wiping it all. Anyway, careful overclocking. I ended up with S tier Ram modules which had run 2400mhz for almost three years straight, and I got it in me to try for 2500mhz seeing others pulled 3000+ from the same chips. I played with fire, and got burned. My Icarus moment, because I was locking up and having to hard reboot over and over until I got a good set of timings and voltages set. But it didnt last, long before I couldn't boot up anymore after that. haha Live and learn, eh?!

1996mhz cpu, 992mhz gpu and 2133mhz ram are really perfect for the switch all around. And thats 1996 boost, 1509-1600mhz range is plenty for the games on the switch and 60fps more is just for benchmarks, not long haul smooth stable gaming.
