Hmmm...
What id try is... This will factory reset the unit btw
On 8.0.1 fw...
1) in the boot repair package, one of them, there should be some blank Boot0/1 files... Look for some for your 8.0.1 firmware... Restore these using either etcher, win 32 disk imager or my hekate mod (switchboot) using the ignore size check option
2) then mount your emmc in hacdiskmount... System/bis key 2 into /save and delete everything apart from 8000000000000120
3) delete savemeta if it exists
4) mount "USER" and make sure every folder is empty
5) boot atmosphere with Sig patches(via fusee primary)
