Updating Bluray Drive Firmware on Linux

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............|
00000010  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

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.

Identification string	Type	Flag
SONY EmerFlashROM	0x2100000000000001	0
SONY PS-EMBOOT 300R	0x2100000000000001	0
SONY BDRW AQUAM(BDIT)	0x1100000000000001	0
SONY PS-SYSTEM 300R	0x1100000000000001	0
SONY PS-SYSTEM V300	0x1100000000000001	0
SCEI EMER-FLASH-8	0x2200000000000002	0
SONY PS-EMBOOT 301R	0x2200000000000002	0
SONY PS-SYSTEM 301R	0x1200000000000002	0
SONY PS-EMBOOT 302R	0x2200000000000003	1
SONY PS-SYSTEM 302R	0x1200000000000003	1
SONY PS-EMBOOT 303R	0x2200000000000004	0
SONY PS-SYSTEM 303R	0x1200000000000004	0
SONY PS-EMBOOT 304R	0x2200000000000005	1
SONY PS-SYSTEM 304R	0x1200000000000005	1
SONY PS-EMBOOT 306R	0x2200000000000007	1
SONY PS-SYSTEM 306R	0x1200000000000007	1

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.
