Hacking Will this guide help for every softbrick Switch to restore to stock?

[switchModBrick]

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.

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.

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

"5.Put eMMC chip from Switch (A) (or any good eMMC chip) to Switch (D)"

Have I to change the physical chip?

Either will do but i'd just use the one that your switch fw is on, so you have those keys with the newer fw.

But my firmware is completly deleted.

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

 

[switchModBrick]

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?

 

[switchModBrick]

During dumping the prod.keys yesterday I get following log. The file wrote fine but is this a problem?

Because of “unable to read keyblobs” and “unable to locate system partition”.

Well aren't you just doing that to get your keys to rebuild your system partitions?

Yes, I am only was unsure if this is a problem for furter steps.

"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.
