Hacking Question Get 6.2.0 keys from bricked Switch

[chardido]

My switch is bricked, I can't boot neither OFW or CF (6.2.0 firmware).

I need 6.2.0 keys in order to use choidujour to restore 6.2.0 firmware (I think pkg2 is corrupted) and I used Hactool and Hacgui to retreive keys, with no luck.

I've read about the impossibility of retrieve 6.2.0 keys without LockPick homebrew. Is that true? There is another way to retrieve 6.2.0 keys?

If someone have another way but he can't post it, he can write me a pm. Thank you

Ehm you're right, but IDK why I'm so stupid and I can't find any keys on google

Google for "Nintendo Switch master_key_01" for example...first entries should be what you're searching for

EDIT:
I've also tried to change TSEC and SBK with mine retrieved from biskeydump

In the command prompt, type "ChoiDujour.exe --keyset=keys.txt fw" without quotes

• If ChoiDujour says it cannot find firmware files or keys.txt, you likely put keys.txt or the firmware files in the wrong location. Try steps 1.9-1.13 again.

Looks like your keys.txt is incorrect Please find a reliable source.

These are the only one I’ve found.


Using Hactool with my "BCPKG2-1-Normal-Main", I've extract some keys. Not all, but a lot of them.
Comparing them with the ones found online, they matched all.

What these errors means?

[ WARN ] Keyblob MAC 00 is invalid. Are SBK/TSEC key correct?
[ WARN ] Keyblob MAC 01 is invalid. Are SBK/TSEC key correct?
[ WARN ] Keyblob MAC 02 is invalid. Are SBK/TSEC key correct?
[ WARN ] Keyblob MAC 03 is invalid. Are SBK/TSEC key correct?
[ WARN ] Keyblob MAC 04 is invalid. Are SBK/TSEC key correct?
[ WARN ] Keyblob MAC 05 is invalid. Are SBK/TSEC key correct?

Because there is a match between Keyblob keys found and extracted

It means that either your nand image is damaged, or your SBK/TSEC key is incorrect. BIS,SBK,TSEC keys are console specific so you can't use someone else's
