Switch doesn't power on after migrating SD card

Blakejansen · Feb 6, 2023

After what I thought was a successful SD card migration from 256gb to 1tb, it seems like my switch is not reliably turning on anymore. I followed the instructions step by step, went into the new emunand and made sure everything was working 100%. All was absolutely fine. I reset my switch and sysnand is perfectly intact just as I left it.

As soon as I tried to use the RCM jig, I go to turn on my switch and I get a black screen. I take the jig off as well as the RCMloader, and I am still having this issue of trying to turn on the switch only to be met with a black screen. Only solution is to wait around a minute and then I can power my switch on again. What is going on here?

Edit: Seems to be working now but what the hell caused this issue? RCM seems to be buggier since I upgraded the SD card.

Edit 2: I am getting a corrupted data message when I try to launch my games on emunand. What a bummer.

Edit 3: Raw Folders are identical size wise. What did I do wrong here? New SD card boots into CFW fine and the emunand backup seems to have worked outside of my games not loading. They ALL show the corrupted data error and the games show as 0 under the system management. I can see that the SD card storage is taken up though....

You might be missing sigpatches or installed them in the wrong folder (Atmosphere and Hekate have their own sigpatches).

I followed the guide on Rentry. Dragged my folders from working SD card to New SD card. Used Hekate to back up my emummc and flashed it back onto the new sd card. Emunand works on the new sd card, but none of the games work and they show up as 0.0mb in system storage.

Edit:Both SD cards are FAT32.

I had the same issue recently when I upgraded my SD card and the only guide that worked for me was this one by stethix.

Edit: Corrected link.

Link is not working. When you say you had the same issue, are you talking about switch having power on issues? That randomly went away. Now the problem is that my games are showing up as corrupted and 0MB although I can see that there is a ton of space being used on both the switch and my laptop. How did you manage to fix this problem?

I think you may need to move the nintendo folder on your sd card root to sd/emuMMC/RAW1/Nintendo

Fixed using this https://gbatemp.net/threads/games-h...-sd-card-using-partition-based-emummc.623818/

"Tools ➜ Arch bit • RCM Touch • Pkg1/2 ➜ Fix Archive Bit"

If anyone else has this problem, this will fix you right up!
