Hardware Missing Bis Keys

[lpoolm]

hi so I have a faulty switch that does not turn on. It boots into Hekate but can not do anything else to boot further.
I have been following a guide to try and rebuild the nand but I need Bis keys and these are missing, the BISkeys file i dumped has HWI, SBK and TSEC key but no Bis keys. I assume this might be why it will not boot?
I have a working hacked switch can I use Biskeys from this? Or is there another option?
Any ideas please
thanks

Try using TegraRcmSmash and the latest biskeydump payload. You can't use biskey from another switch.

Thanks, any idea if it will brick or just not work?

if you refer to what I wrote above, no.

any other ideas please?

So I have used Lockpick and Biskeydump and have received the following errors.
It looks like the data is corrupt.
Is there anything I can do to recover or is it totally gone?
Thanks

If you have HWI, SBK and TSEC follow point 8 here:
https://switch.homebrew.guide/usingcfw/manualchoiupgrade

https://sdsetup.com/biskeygen

Try the latest Lockpick RCM 1.8.0

Thanks, that works great. It created my Biskeys, however now when I enter them into Hacdiskmount it says:
FAIL! Entropy: 7.988 (tested 16384 out of 16384 bytes)

The guide says if it is red the keys are wrong and can not continue?
I have tried writing them in and copy and paste but get the same error?

Thanks, have asked in the second thread, a few have mentioned the issue but no sign of a fix

Maybe your eMMC is corrupt. Try a reflow or even a reball at the eMMC if you can.
I recommend that you ask @mattytrog for an opinion, maybe he can help you.

Hi guys! Have anyone here encountered a solution for those issues? I'm expiriencing something similar, can't boot to stock rom, just sys and emuMMC. So without the micro sd card, my switch looks like somehow bricked, as it keep giving a black screen with some text, asking to turn the system of or rebooting, followed by the serial code and firmware version. My stock rom and sys nand are on a lower firmware than my emunand, and i enabled the gamecart slot, and played a retail game on the emunand, if that helps. I'm grateful for any help.

I never fixed mine, pretty sure I've sold it on for spares.
I still haven't seen a solution.

BIS keys are the Built In Storage keys, they're used for encrypting / decrypting the nand.
For @SwGirlAdv try following this guide, if you have the BIS keys.

Maybe @shchmue can give ideas as to why Lockpick couldn't dump Ipoolm's?

Edit: Linked different guide

Thank you, but actually, my issue was already solved, with the help of member @LegzRwheelz, I put what helped me on noob paradise thread.
