Homebrew Question Bisskey edit

[Alschepmist]

Hello it s possible if i can read a partition of the switch to edit the bisskey on it or change the bisskey ? What i want to do is to change the bisskey of perhaps prodinfo and then restore it to another switch with proper bisskey . I have 2 console 1 working and the other i cant acces to the partition bisskey don t works thanks

I'm pretty sure the bis keys are stored in rom so you can't edit them but if you have the bis key for both systems you could decrypt the data from one system and then re-encrypt it with the bis key for the other system. It's probably not a good idea to use the prodinfo from one switch on another though because it contains calibration data specific to it's hardware.

How can i re encrypt? What program i have to use? Thanks for reply

If you’re trying to do it with prodinfo, don’t, all you’ll get is a nice expensive brick.

you cannot restore an effed up prodinfo without proper backup
or in other words
you cannot unbrick your brikachu/pozznx bricked switch

You would need HacDiskMount by Rajkosto.

Didn't Mattytrog figure out a way to do partial restores with a modified build of Hekate?
