Location: /dev_flash/vsh/etc/index.dat

Unpacking[edit]

contains content similar to version.txt about firmware version/build/date etc. and can be unpacked with undat (you´ll need the dat keys for it) - it is used in MFW Builder 0.2 in the spoofer task.

The keys are public known in aes example papersheets :

  • "The Laws of Cryptography: Test Runs of the AES Algorithm" 2002
  • "Applied cryptography and network security" 2003

and alot others

Correlation to PUP version[edit]

PUP Image version - versus Build number in index.dat/version.txt[edit]

PUP Image version is located at offset 0x10-0x17 example OFW 3.15 CEX:

 Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
   
 00000000  53 43 45 55 46 00 00 00 00 00 00 00 00 00 00 01  SCEUF...........
 00000010  00 00 00 00 00 00 94 8F 00 00 00 00 00 00 00 07  ......”.........
   
 hex:948F (PUP image version) = dec:38031 (index.dat/version.txt)

On official firmwares the value is the same, but they are used in different stages. PUP image version is used by ps3swu.self (updater) when installing firmwares in normal and recovery mode. Index.dat/version.txt is not looked at when installing (hence, why you can have a 3.15 firmware with Image version correlating to 3.15 OFW and spoofed to look like a 4.11 firmware).

For MFW's/MFW Builder, the Image version is increased by +1, which is why you need to use Recovery mode to install a same version firmware.
