    Im always right :rofl2:

    If you have not yet done so yes dump the full raw emmc
    Make sure to have atleast 30gb of free space. and the sd card is formatted to exfat.

    ok, that's all fine and dandy but I still don't know why the dumping procedure is moving extremely slow in my case. like I said before, if dumping 2.5GB took over 2 hours, then dumping 30 GB would take over 25 hours. which is too much, wouldn't you agree?
    So do you have any ideas what could I try to solve this issue? because I'm not letting my switch stay on for that period of time.

    I have no idea it does seem unusual, maybe a defective sd card, maybe when the sd card is near full its slows down or have issues...

    Try another sd card and just dump system part again see if you get different results.

    If I have the rawnand.bin file split into multiple files automatically, can i continue the restoration process like normal? Or should I merge all of the files first?

    Why did you not format the sd to exfat format as stated ? But if you want to join those parts use one of these https://github.com/CTCaer/hekate/releases/download/v4.0/joiner_scripts_for_windows_linux_macos.zip

    This hekate version only restores if it is whole file it does not restore partial, and it only restores exfat format..
    You can merge those files but then you still need exfat format sd to restore that file

    then if you had the format as exfat , then you did not have anoth space left and it output was partial...
    If the dump completed successfully then just merge the files. if your unsure, then try again make sure to have atleast 30gb and in exfat format just for the rawnand.bin dump Option is called full raw emmc

    Very strange,,, Only reason for it to fail verify is if the contents of sd card does not match the contents of the nand the system emmc dump
    Guessing you are using the files attached ? hekate 4.0 ?

    Hey have you dumped the rest on the same sd card and all is ok ? Cause even some new sd cards could be fake,
    and what happens then is it will just overwrite continuously,,

    Hmmm..
    Only options i can give you is ,
    Obviously backup what you have on your sd FIRST. Your backup etc.

    Try another sd card formatted to exfat. and just dump only the emmc sys..
    And see if it verifies .

    Or try the 3.2 version of hekate. as my guide is running latest files now. and there may or may not be a issue with hekate 4.0.

    Id def try a dif sd card or reformat a sd card tho

    If you check your verify options it should be set to full not fast..

    verification=2
    0: Disable Backup/Restore verification,
    1: Sparse (block based, fast and not 100% reliable),
    2: Full (sha256 based, slow and 100% reliable).

    Gambia, The
    I have the same problem, did you mange to solve it? I started out on 4.0.1 and updated to 5.1 with ChoiDujourNX.

    My SD Card (exfat) looks as follows:
    • root
      • Backup
        • "letters and digits"
          • dumps (fuses.bin ; kfuses.bin ; tsec_keys.bin)
          • partitions (10 files total, including "system")
          • pkg1 (nxloader.bin ; pkg1_decr.bin ; secmon.bin ; warmboot.bin)
          • pkg2 (ini1.bin ; kernel.bin ; pkg2.bin)
          • restore
            • partitions, emtpy folder
          • boot0
          • boot1

    I have also tried to copy boot0 and boot1 to the root of the SD card. The payload I used was the ''hekate.bin" attached to the first post in the archive "payload to be used..."

    How are you trying to run kezplez what cfw method are you using ?
    whats your sd card format

    Try removing the leters and numbers and just have the folder called backup
    Kezplez may not read the new folder name.
