So i had a bad nand flash but i can still get zell working or what ever it is called so i need a fix to flash the nand from zell please help.
Take your backup nand and rename it to updflash.bin, put it on the root of a USB, plug it into your turned off console, then start Xell. Wait about 5 minutes for it to flash and you should be good
For now to fix it you just flash your old nand that you copied. Somewhere along updating you messed up so just keep trying until you get it
