Did you not backup your biskeys on day 1 ? on your very first backup ?
anyhow
restore most earliest Nand backup, or working rawnand/image with hekate..
Make sure it boots with hekate..
Then once into the system run choidujourNx with latest system version files on sd you wish to install..
Or use choidujour.exe and rebuild yourself a new image.
If you pulled biskeys from that console, and console was working when pulled then they are the biskeys for that system and are working. The biskeys do not change on there own.
Try use the biskeys against your old backup and see if it passes...
Start again budd from the very first backup of system you ever did and build on that.
Ignore fuses and versions, as if you boot with hekate it should boot them all.
Ask
@mattytrog Nicely and im sure he can fix ya prodinfo issue...
Something you did is corrupt and it wont match..with ya biskeys.
