I did a clean backup the first time when my console was on 5.1 clean sysnand. I got rawnand.bin in 14 parts and BOOT0 and BOOT1 files. Now I'm on 8.0 and updated via choidojour always with autorcm on, never went online. I want to restore my old clean nand back up and leave no clue about cfw. Do I need to downgrade first to 5.1 in order to restore my nand backup ? Or just do it directly in hekate with my files ? Also I wanted to know when and how to disable autorcm, i installed autorcm AFTER the backup.
