Introduction

  • No use actually but just for the sake of scientific research :)

Current BD FW Version

Using Storage Manager service get_version: 

sudo ./ps3dm sm get_version
00 03 00 50 00 00 00 00

Using SC Manager service get_region_data: 

sudo ps3dm scm get_region_data 8 | hexdump -C
00000000  00 03 00 50 00 00 00 00  00 00 00 00 00 00 00 00  |...P............|

Or reading it from BD drive istelf, see http://www.ps3devwiki.com/wiki/BD_Drive_Reverse_Engineering#Get_Version.

BD Drive Type

  • Use SCSI Inquiry to fetch BD drive identification string.
sudo sg_inq /dev/sr0
  • 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: 

if ((type & 0x00FFFFFFFFFFFFFF) == h_id)
   FW is OK
else
   FW is NOT OK
fi

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.
