* Incredibly useful for grabbing ps3 firmware dumps using DRAM exploit + TOCTOU bug in bd fw update :)
* No use actually but just for the sake of scientific research :)
* see https://www.youtube.com/watch?v=LNFgKBfo2d8

=BD Drive Type=
 
* Use SCSI Inquiry to fetch BD drive identification string.
 
<pre>
sudo sg_inq /dev/sr0
</pre>
 
* PUP file contains several BD update packages.
* Update manager matches BD drive type against '''h_id''' from update package header.
* h_id is at offset 0x8 (8 bytes) in the update package header.
* E.g. h_id from BDPT_FIRMWARE_PACKAGE_306R.pkg is 0x0000000000000007.

BD drive type and FW type check:
 
<pre>
if ((type & 0x00FFFFFFFFFFFFFF) == h_id)
  FW is OK
else
  FW is NOT OK
fi

=Sending BD Firmware to BD Drive=
=Sending BD Firmware to BD Drive=
* BD update package is first decrypted and then sent to BD drive.
* BD buffer 0 is used to send BD firmware to BD drive.
* The BD firmware is sent in chunks of size 0x8000 bytes with SCSI command WRITE BUFFER mode 7.
See my bd_update_fw tool for PS3 Linux.
http://gitorious.ps3dev.net/ps3linux/bd-tools
=Test=
* Tested with my PS3 slim and OtherOS++.
* It should work on PC too. You can update your BD drive on PC but first you need to authenticate it with '''bd_get_version'''.
* Downgrading works too. I tested it myself and downgraded from 3.50 to 3.40 and back again.
* Use '''ps3dm sm get_version''' or '''bd_get_version''' to verify that the new version was installed successfully.
