[Q] Some creative thoughts for Nook Color Hackers

---

It looks like it might be possible to subvert the signing of updates. I say might because if I was doing this I would embed several key checksums into the firmware and use them when loading a bootloader or an update.

The CERT.RSA file is included in the *update.zip file but the machine lacks the communications needed to verify that the signature is valid. (Evil Laughter) Therefor someone could create a completely false keychain and sign the update with the key they generated.

Of course that might work for the install and then fall flat when you actually connected, but a little creativity might get you past that, assuming that you even care.

This might be the hack needed to semi-permanently roll back the locked bootloader, but I do not know enough to implement it.

One bit that I think will be needed is a kernel module to re-direct user-land read access to the boot loader to a backup of the locked bootloader so that those apps (netflix) that check this will see what they expect.

Anybody care to attempt part of this?

The boot loader of the Nook Color is not locked. Only the Nook Tablet.
