Don't think so, if it, there will be a lot of hacked game saves with all trophys opened!

Hope helped +rep

360 dvd fw is encrypted, in the original xbox was not.

if sony can update the drive fw is not possible to get the decrypted vesion of this fw from an update before it gets encrypted with the BD key?

Yeah - your right, they will not allow a non-signed firmware to be installed.

I ask because on the 360 drives for example you have the drive itself with the circuit board all as 1 complete unit. On the ps3 they almost feel like 2 seperate parts. i wonder would it be possible for lets say sony to make the circuit board for the drive and have the firmware on the board? and upon being connected to the drive itself the board somehow writes the firmware to the drive?

Does anybody know if the ps3 decrypts the firmware for the blu-ray drive at any point or does that not even matter? is the official firmware for 360 drive encrypted? if so, was the encryption RE or was the 360 used to decrypt it. thanks for the reply demonhades.

doing some reading and noticed this little tidbit of info. can somebody confirm or deny?

The drive logic board and motherboard are tied to each other with a unique crypto-key. Without the right drive board you can't even perform system updates (it will fail around 65% when it tries to flash the drive firmware, and you will be stuck forever). So DO NOT attempt to update the firmware until you have the matching drive board.

if that really is accurate than that means the ps3 upon system updates, erases the blu-ray drive firmware and rewrites it. that would be awesome if the ps3 could do all that. if i had a test or debug unit could one actually test this stuff and rebuild the system firmware update with a modified blu-ray firmware?

Few quick answers - the BD firmware is on the BD drive, it is decrypted by the logic on the BD Drive.

If I recall, some 360 drive FW's may have been encrypted (don't hold me down on this one though - not a 360 guy!)

The advantage of the 360 drive hacking vs the PS3 is that microsoft used fairly standard designs, while sony went about it a different way - making it themselves.

An interesting note re the drive FW, on a PS3 TOOL, the entire update process is recoverable if it crashes - with the exception of the BD drive flash - so yeah, it probably does as you just stated.
