Syscon Firmware is the firmware stored on the System Controller EEPROM (see Syscon Hardware). Updates are stored in update packages within the Update_files.tar of a Playstation Update Package (PUP). Syscon Packages appear to always be 5KB (5376 bytes) in size.

Rows marked in gray are .pkg that was superceeded by a newer version with the same SoftID

This means from syscon perspective notible firmware changes where made at 1.30, 1.81, 3.00, 3.40 and 3.41 that affected retail and debug PS3 models

  • Firmware 1.30 (December 6, 2006) added Backup/Restore
  • Firmware 1.81 (June 15, 2007) ?
  • Firmware 3.00 (September 1, 2009) resulted in Class action suit for BluRay reading problems
  • Firmware 3.40 (June 29, 2010) ?
  • Firmware 3.41 (July 26, 2010) ?

NonRetail syscon

Remember, Debug/DEX consoles are normal retail consoles with different TargetID, so only those that have a nonretail board have deviating patches (like the CXR713F120A found on the DECR1000A TOOL/DECR).

Tool/DECR don't have patches, they flash entire firmwares.

Deviating from Retail

Please note that without info about the SKU the listing of ID's is pretty useless

sys_con_firmware package 1.00-1.30 1.30-1.80 1.81-2.80 3.00-3.30 3.40 3.41-4.11 SoftID Notes
? No No No No No No 0B67 Debug/DEX

Usage

The firmware PUP's contains a collection of patches for all the different hardware revisions of syscon's chips used in different motherboard models.

The ps3swu.self (system updater) decides which applicable Syscon Hardware is present and installs the needed package update(s) accordingly (via updater manager ss service).

Which syscon version and which patches are installed can be seen in More_System_Information

Decryption

Packages can be decrypted with the unpkg tool. Decrypted content of the updates appears to always be 0x1000 bytes (4KB).

Header

The header format is partially unknown at this stage. All the Firmwares patches are written in little endian.

Observations

  • The first 4 bytes (0x1B2D700F) appear static in each package.
  • The next 20 bytes appear to change with each package
  • The following 12 bytes (0x0000000000100000C00F0000) also appear static, but it's the firmware size and fw size - header size; infact if correctly converted to little endian 00000000 00001000 00000fc0, where 00000000 is Unknown, 00001000 is 4096 in dec (file size) and 00000fc0 is 4032 in dec (update size).
  • On the DECH fw, the update works in the same way: 000000004000060000000600 converted will be: 00000000 00060040 00060000, where, 00000000 is probably padding, file size 00060040, 00060000 update size
  • the first 40 bytes probably are IV + HASH + update infos. probably the algorithm used is AES.
