So long story short. I made a nand backup of 6.1.0. My girl updated the system to 6.2.0. So I went in to restore my old nand and boot 0/1 and when I tried to restore the raw nand gpp and I got the error the size is different than the sd card. But the boot 0/1 worked and now my switch wont boot at all. Any fix to this? I can still access rcm.
