There are some key statements like on page 19
If you attempt to open a ‘spoofed’ firmware
created by hex editing or with samtool, it will report the key as
16-bytes of FF because the program thinks that it is a Hitachi
firmware (both stings are patched).
This would also imply it is important (except for those doing Hex editing in method 1) to start these process with the generic firmware files (those called Xtrem52a.bin, Xtrem52b.bin, Xtrem52c.bin, Xtrem52d.bin) and not
the version specific files (52x-htyy.bin like the 52b-ht47.bin).
The later (52x-htyy.bin) if used with the more automated tools (FW toolbox) would be seen as Hitachi firmware and the key patched to position $4F00 and not in the structure of preamble starting at position $4000 used by the samsung.
So the version specific file (52x-htyy.bin) should ONLY be used with the Hex editor?
Happy I never use these but what would be the impact of someone using patched at $4F00? and could it be recovered?
