Also, just a comment on checking the 0x00 and 0xFF areas, I have a few samples where areas that usually are 0xFF are indeed 0x00. I am not sure what conditions cause this but I assume it's from different boundaries from previous firmwares.
Basically, areas that are 0xFF will be so because NOR flash memory in it's "erased" state contains all 1's, a write operation is able to change a 1 to a 0 however a block erase operation is required to revert 0's to 1's. Areas that are 0x00 are simply where blank data has been written over an erased block, usually to fill up a boundary.
As for a final report, it would be nice to give a pass or warnings on what specific parts of flash are incorrect.

is the download section getting re-opened then?
otherwise its a bit pointless moving it there if it cannot be accessed.
^^^dont take that as a piss take or anything. its just a question
