    Help me please,i think my 3ds is "semi bricked". I really dont know much about this. When i try to turn on the system, the blue led light turns on but inmediately turns off. I tried the hack where you access via the luma menu but its not working anymore, it loads for a bit and then it appears"Unable to mount CTRNAND or load the CTRNAND FIRM". I dont know what to do uu. Yesterday i updated the luma but i dont think that helped.

    This probably won't help you, but just in case... The one time my newly modded New 3DS XL would start with the blue light coming on and then turn itself off it turned out that I didn't have the micro SD card was not fully seeded/into position. Once I pushed it in all the way, everything was fine.

    Good luck and I'm sure others will respond with better answers.

    Try putting the boot.firm from the luma releases page on your sd again, sounds like the firm might be corrupted and you copied the corrupted one to the CTRNAND partiton.
    You can get the latest luma here: https://github.com/AuroraWright/Luma3DS/releases/latest.
    (Since it's unable to mount the CTRNAND that might mean you have a corrupted CTRNAND partition. If you're able to get your 3ds to boot again I'd recommend doing a ctr-transfer)

    First, make sure boot.firm is on your SD card, in the root. If it's there and the console still isn't booting, try backing up the card to your PC, formatting it (make sure you format as fat32 and not exfat), and restoring the backup. If that doesn't work, try another SD card. They're dirt cheap nowadays, you can pick up a decent size for less than $20.

    You download the Luma3DSv10.0.1.zip and put the boot.firm from the archive to the root of your sd.
    You also should check out the first section of this page: https://3ds.eiphax.tech/sd.html
    For the nand backup you might wanna make a backup when the issue is fixed (you make NAND backups with godmode9)
    And yes you do have to replace boot.firm on sd root

    Try these steps

    [1]: Boot GodMode9

    [2]: Press the Home button

    [3]: Select scripts

    [4]: Select GM9Megascript

    [5]: Select Scripts from Plailect's Guide

    [6]: Select Setup Luma3DS to CTRNAND

    [7]: Input button combo

    [8]: Wait for the process to complete

    I hope this helps -Ryu

    Okay thank you for clarifying what were you doing prior to the problem

    have you tried the recovery mode? if not press A+R+L+Up(DPad) while booting your 3ds this may help I am unsure your problem sounds kind of like a hard brick

    nothing special really, i havent used my 3ds in a long time(i installed cia and that stuff in May i think, using a youtube tutorial) and this saturday when i tried turning it on, the blue light just went off almost inmediately and the screen was still black. After a few attempts it turned on but almost every time i tilted the upper screen it crashed and i had to restart it(and so the blue light problem happened again). However sometimes the screen showed the message "Unable to mount CTRNAND or load the CTRNAND FIRM". I have just replaced the luma boot firm and it turned on normally and it has been like 5 minutes and it hasnt crashed but im scared that if i tilt the screen ever so slightly, the problem of the led light turning on and then off will happen again.
    Update: i moved my 3ds slightly and it crashed again :(

    i tried accessing luma by pressing select and it showed "the firm modules are too large"

    update: tried turning it on again and "Unable to mount CTRNAND or load the CTRNAND FIRM" again

    This means Luma3DS has trouble finding or loading/patching the NATIVE_FIRM. Your 3DS firmware is definitely softbricked.
    1. Copy everything off your SD card.
    2. Quadruple reformat.
    3. Full Write + Verify test the empty card in H2testw. Do not skip.
    4. If the card passes, delete the *.h2w test files.
      • :!:If you get this error message, the hardware failed card must be replaced. Go back to step 1.
        • The media is likely defective.
      • If you use a fake or dying SD card, any attempts to repair the 3DS firmware in the later steps will super softbrick your 3DS.
    5. Copy everything back to your SD card.
    6. Backup your SysNAND *.bin image for safety.
    7. Attempt 3DS firmware repair with CTRTransfer + System Update to 11.13.0-45.
    If your 3DS is still softbricked at this point,

    8. Restore the SysNAND with the image made from step 6.
    9. Re-attempt 3DS firmware repair but this time with CTRTransfer (Type D9) - CTRTransfer + System Update to 11.13.
