This is the programming screen, you can manually program using this code.
The firmware is a different mess.
It seems we are not able to dump a ROM from device, at least not that I have seen.
Why do you ask, because what Microsoft did is they have different build flags.
-Debug -Beta -Retail -Ship
From inside there, the Ship, has strict settings on it. One of those is that it cant dump the ROM.
So that is where we are at right now. I have a few ideas to try but I am not going to test for a few days.
We shall see though.
So that is what I have figured out so far.
New site is launched today.
