Yep, to update the PK the update must be signed with the current PK. Updates to the KEK must also be signed with the current PK.

The memory offsets are published somewhere. I remember reading them. It's something like 0x00007000-0x00007FFF. Is that what you're talking about? I'm sure I could find the docs again.

Oh yeah, it was right here on the forum.

http://forum.xda-developers.com/showpost.php?p=31622172

The qfuse register is held in a 4KB starting at 0xFA700000. We should be able to read the shadow region at 0x00706000-0x00706FFFF if we can get tools to run.

The memory map graphic is a 2KB block (MSM8660), but it should be roughly analogous to the 4KB block (MSM8960 - lumia 920/1020/etc)

Working on finding the docs. Downloads aren't working now, and I can't find them on this computer.

Depending on the certs in there, there is an outside chance that I could con it into running Windows PE ARM so we would have the basis to run some good tools... but that is a very outside chance (IIRC the signing certs between RT and WP devices are from different CAs).
