    Need more info
    Is it your nand you restored?
    What system version are you on?
    What system version wore you on when you backed up the nand?
    What payload are you trying to use?

    I restored my nand, which is a 3.0.2, i restored it from 5.1.0 (as i had the same issue, was working fine on 6.0.0 and 3.0.2). Payload? None, attempting to boot into OFW, also tried Hekate for CFW Atmosphere, and ReiNX payload for ReiNX, both same issue.

    You cant simply restore your old nand unless you upgraded without burning fuses. What is your fuse count?

    How did you upgrade 6.0? If you did it through official firmware then you wont ever be able to boot OFW again on anything lower than 6.0

    always check your fuse count before doing a nand restore. Not doing that gives you this problem and you're switch will be a permanent brick. Can you still boot in to hekate ? Did you also made a nand backup of your switch with firmware 5.1.0 or whatever you were on ?

    Fuse count is 4, 3.0.2 NAND backup restored. I can boot into Hekate, I didnt make a backup in 5.1.0 as i couldnt get into it when i updated with ChoiDujour

    Your fuse count is correct so it should work with a nand restore of firmware 3.0.2. Did you try to do the restore again with hekate ? If it doesn't work then i suspect your nand backup to be corrupted

    is it formatted exfat ? Because only fat32 works on those lower firmwares.

    Well you can always try with an fat32 card instead seeing that there aren't many options left , the only thing that you can do is do a nand restore again and if it still doesn't work then theres probably something wrong with the nand backup

    how big is the nand backup ? Because if you used the 32gb card you got a partial nand backup and that is your problem right there since you have to use a 64gb card for a nand backup and restore. If you did use a 64gb card to do the backup then you're in luck otherwise ur fucked. If you did a partial dump on sd then you should also have another part by doing the dump a second time and you can use a joiner script to merge them together. If you did not do that and only have a partial dump well it's a perma brick then

    I used partial nand backup and put them together to make a 30gb nand file. I dont have a 64gb sd, and i saw posts saying Hex Workshop and HacDiskMount works through USB cable.

    well buy a 64gb card and do it with that. I'm pretty sure it will work that way

    I might see if thats my only option, its strange tho, when i restored my NAND through the cable, it got rid of my blue/purple screen so i assumed it would've worked. Thanks for help i guess, if anyone else has ideas, please post them!

    Did you restore the rawnand AND boot0/boot1 of that firmware? Because if you just restored the rawnand, you didn't fully restore the NAND since boot0/boot1 are firmware specific

    There is one more thing you can try and that is use ChoiDujour method again, if your backup nanad is no good then find xci with that firmware and flash again with firmware 3.0.2 dump from xci update.

    Did you make a backup of boot0/boot1 after installing AutoRCM?

    If your answer is yes, the only other thing I can think of trying is rebuilding your firmware files with ChoiDujour, the Windows version.
