    I used the BOOT0/1 from Hektake Backup, didn't work
    I used the boot0/1.bin from builtin SX OS NAND Dumper and it worked

    hope this helps

    Wooohoo! I dont know why, but it works! Backuped the SD Card. Formatted it. (no problems there) copied everything back, except one old nand backup. Booted emunand with cfw. And it works without any problems! Strange Bug!

    ... Everyone with the black screen boot problem - how much space on the sd was left?

    I had the same problem. Tried replacing boot0 and boot1 from backup and it didn't help. I started to wonder if it had anything to do with the fact that my emunand was without exfat support. So I copied the emunand to another card that is formatted with fat32 and the emunand booted up right away. I then upgraded the emunand firmware to 6.1 with exfat support and copied that emunand back to my first card (exfat). Now the first card that didn't boot works fine too! If your sysnand doesn't have exfat support and you are using an exfat card to create the emunand, try what I did and see if that helps

    I have got 6.0.0 emu nand to boot, after doing emu nand 3 times with black screen. I looked about, simple is make a backup of Boot0.bin and boot1.bin (you should have these before playing with emunand!).
    Make your emunand, boot cfw (none emunand) open file explore, delete the boot0 and boot1 in emunand and then past the ones from your backup.
    You can also do on pc etc, for me doing like that works!
    Remember I’m using 6.0.0 so can’t comment on any other fw I can’t comment on.

    Had the same problem as not being able to boot emunand (black screen). This is what I did to fix the issue:
    *In SX OS boot menu, go to the nand back up option and select dump nand.
    *On the next menu, press advanced options and enable only "boot0" and "boot1"(other options should be disabled).
    *Do a nand backup of the selected files. Should only take a few seconds.
    *Turn off your switch and place your SD card on your PC
    *Browse to "sxos/backup/" folder.
    *Copy "boot0" and "boot1", then browse to "sxos/emunand/" folder.
    *Paste and replace your copied files.
    *Now try to boot emunand normally as you would before.

    That fixed my black screen issue. Hope that others can fix their emunand as well.

    ps
    does anyone of you with fw 3.0.1 was able to proper set up emunand on SDcard ?

    Are your sysNand and emuNand on the same firmware?

    I had the same problem and this is what I did:
    Just copy the boot.dat from an old SX OS 2.0.1 that doesn't use emunand from SD.

    The new SX OS 2.3 copy the 2nd NAND to SD card but the 2nd NAND is always here. It's just a copy, not a move.
    So if you have a blackscreen with SD emunand, roll back to previous SX OS and check if your NAND EMUNAND is still booting.
    If yes, delete emunand folder from your SD card and make a new copy with sx os 2.3

    does the switch prompting me to update to 6.2 to use the sd card have anything to do with it? it's asking me that when I boot in ofw.
