boot fails after OEM factory reset, refresh TOTP/HOTP, update checksums and sign all files in /boot
gpg BAD signature from OEM Key
Invalid signature on kexec boot params

Any advice on where to look to understand this process better would be much appreciated.

Hi @lochlan I believe my colleague @mladen has already replied to you via email.

I have the same problem after installing upgrades. Please provide instructions on how to reset the boot key.

Hi @bronc

You can do a OEM factory reset of the Librem Key by following these steps:

I would also advise to read this section of the Pureboot quick starter guide regarding changes in the boot partition files:
