Thank you,
are the PikaFix Pack files that I generate by my one or can I download them?

Should I use my old prod.keys backup or these I made yesterday because they are a bit different, is this normal?

All the files in pikafix are pre-generated, except your own keys which are needed. If you just need the pure prodinfo fixed, then please use method 2 or 3 as method 1 is getting re-written.
Sorry for this question but what is the guide I have to follow first in the interest to restore my soft broken Switch into a workable System?

rebuild BOOT files. https://gbatemp.net/threads/how-to-build-clean-boot0-1-files.591409/

fix cases with no backup/destroyed NAND: https://gbatemp.net/threads/guide-nand-rebuilding-for-no-backup-broken-emmc.593995/

Thank you so much for helping me.

Probably second link first, and if you have an issue with prodinfo stuff or freezing on boot let me know :3

Thanks, do I need to follow your tutorial first, because the Nand Rebuilding guide for the pikaFix files links to you tutorial?
Is it enough if I download the files you linked?

in their guide it's optional, but if you do decide to use the pikafix files, download them then start at step 5

Right but your fuses aren't. Everytime you update to a new version the switch burns a fuse so you can't downgrade and run a lower FW. Hence you should use the most current keys from the most current/installed/deleted fw on the console.
Thanks, that helped me a lot in understanding how this keys work.

The only thing I am confused now is following, I bricked my Switch during an fw update, can It be that my keys are broken because of this?

And where are this safe because I insert a some wrong Nand and Boot (how I sayed completely f***), can it be that they are wrong because of this?

Or are they independent from the BOOT1/2 and NAND?

prod.keys are mostly shared between all consoles, except they contain your console unique biskeys which are used for the partition decryption of prodinfo and system and such; it is possible for them to be broken, but they are tied to your physical console processor.

If you have an older prod.keys and a newer prod.keys, check to see if the biskeys match and if they do odds are you are in luck

How can I see the biskeys In the prod.keys file?

open the file in a text editor and they should be at the top.

Biskey 2 and 3 are identical

I think I have luck because my bis_keys are equal for both prod.keys files.
I have noticed that the newer file shows “mariko_master_kek_source_05[…]” but my Switch isn’t mariko is this a problem?

"11.Open key.dat (D) in step 4(c) by text editor (or rename to key.txt first if you want to)"

I can't find the file key.dat on the Switch SD-Card.
