    Hello

    I booted up my old 3ds with the SD card inserted but I couldn't get into the Home Menu because I awlays got an error. I took out the SD card and reinserted it, I get into the home menu but now it can't read my SD card. Put it back into the computer and it seems to be fine. Everything worked fine 2 days ago, why this now?

    EDIT: my extdata folder seems to be corrupted, i let my pc fix it and now i can access the folder, but my 3ds still can't read it. It still says the software management information is corrupted.

    Check for fake SD card.
    1. Copy everything off.
    2. Reformat at FAT32 + 32 KB cluster size. Guiformat.
    3. Full Write + Verify Test the empty card. H2testw.
    4. If the card passes without error, delete the *.h2w test files.
    5. Copy everything back on.

    No, uninstalling CFW will make it harder to troubleshoot. Continuing...

    6. Remove and reinsert the battery. Try booting the 3DS to HOME Menu without an SD card.
    If it goes to HOME Menu without the card.
    7A. Try it again with the SD card.

    -or-
    If it does NOT go to HOME Menu.
    7B. Put the SD back in the 3DS. Turn on the 3DS and hold the (Select) button. If you see Luma3DS configuration, what version is it?
    • Default option settings should be like this:

    Did you ever used Checkpoint or JKSM save manager, creating backups for all your game saves and extdata?

    Depending if you answer yes or no will determine what you'll do for post 3DS recovery.

    Edit - Opps, I missed some other pre-check steps you should try first.

    Problembehandlung (Troubleshooting)
    • Schwarzer Bildschirm beim Start des SysNAND (Black screen on SysNAND boot)
    • Home Menu extdata bereinigen (Clear Home Menu extdata)
    • Schwarzer Bildschirm beim Start des SysNAND nach der Installation von boot9strap (Black screen on SysNAND boot after Installing boot9strap)

    For any HOME Menu games you wish to avoiding reinstalling or not losing their saves, you're going to need to retrieve these files found in your [1:] SYSNAND CTRNAND: movable.sed and the *.db files [ certs / import / ticket / title / tmp_i / tmp_t ]

    8. In GodMode9, go to that drive, find them, and use the Copy to 0:/gm9/out to your SD card. Verify you have all *.db and *.sed files before moving to the next step. Set these aside safely on your computer along with a copy of your Nintendo 3DS folder.
    If you have a backup of your SysNAND.
    9A. Benutzung von GodMode9 - Wiederherstellen einer NAND-Sicherheitskopie
    (GodMode9 Usage - Restoring a NAND Backup)
    If you do NOT have a sysNAND image.
    9B. CTRTransfer
    10. Check again if your 3DS is able to boot to HOME Menu.
