Hacking Corrupt nand

[Ttm3]

Disclaimer I'm completely noob with this. I've fixed hardware but I've done no modding, cfw, hacking, etc.

I'm having a hard time finding exactly how to tell if my nand is corrupt and if it is how to rebuild/repair it. I have a switch that won't load past the Nintendo screen. I managed to boot into hekate and make a backup but that's as far as I'm comfortable and where I've stalled out. Any help would be greatly appreciated.

Is it possible to find the consoles serial number through hekate, biskeydump, lockpick,etc?

If you have no NAND backup and have your keys obtained via lockpick you can try rebuilding the NAND via Choidujour (PC version).

So when I run lock pick it shows everything being corrupt.

see if you can get your biskey via the biskeydump.bin or via lockpick_RCM, you need to obtained it from one of the two.

So both lockpick and biskeydump give errors. They both seem to output some numbers but both show errors along with it.

Lockpick shows " keyblob 1 corrupt" then it has some data output. Then "keyblob 2 corrupt" then some data output. It does this for 5 keyblob.

Biskeydump looks like it does output some data from what I can tell but does say "keyblob decrypted using current sbk & tsec keys not valid" & "error deriving device key data"
