In theory you should be able to patch the v40, v46, v47, v58 firmwares
to reply back as v59 which will help those that have "downgraded" to
an older Hitachi from their original Hitachi version.
The E66 error appears it seems only on those units which people have
used on Live and Upgraded the dashboard since stock version, and
then afterwards have swapped their DVD drive or replaced it with an
older "version build" then what they had before in their system, and
applied the newer "fall update".
This idea of patching the Hitachi firmware will not currently help
those that have switched from a Samsung drive to an Hitachi,
or vice-versa, only for those that have downgraded their Hitachi.
You need to change the following locations:
starting at >2030 (2 bytes) backwards version becomes "95"
starting at >20D4 (2 bytes) forewards version becomes "59"
starting at >20DE (8 bytes) ver. build date becomes "06/01/24"
and the same change again at:
starting at >3D49E (2 bytes) forewards version becomes "59"
starting at >3D4A8 (8 bytes) ver. build date becomes "06/01/24"
starting at >3D51C (2 bytes) backwards version becomes "95"
And then you need to "encrypt" the hex-edited firmware before flashing:
firm e upped.bin upped-e.bin <---- Encrypt the "upped" firmware
And finally you need to "flash" the changed sectors:
47flash H upped-e.bin 90002000 1000 <---- Flash the first changed sector
47flash H upped-e.bin 9003D000 1000 <---- Flash the second changed sector
NOTE: The following changes currently have only been tested
on the NON-STEALTH versions of firmware, if you are trying to
do this on a STEALTHed firmware you MAY also need to first
UN-STEALTH your firmware by doing the following:
firm e orig.bin orig-e.bin <---- Encrypt the untouched original firmware
47flash H orig-e.bin 90033000 1000 <--- Flash back the READ part, to unstealth the firmware
P.S.: In the above examples and commands, replace the "H" with your CORRECT drive letter.
AGAIN I MUST WARN YOU PLEASE READ THRU EVERYTHING FIRST, AND ONLY TRY THIS IF YOU ARE
SURE OF WHAT YOU ARE DOING AND UNDERSTAND ALL THE RISKS (BRICKING YOUR DRIVE) IN DOING SO.
found this, this is as close to an answer as i can find, i'll be the guinea pig and let you know how it goes.
