Editing Syscon Firmware

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.

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 [[DECR-1000A]] TOOL/DECR).

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

Factory cp comes with 0.8.8 (corresponds to syscon fw size 0x60000)<br>
it is VERY likely that it is not possible to go below this point, so any smaller size would likely cause a brick (see [[Talk:Communication_Processor]] for more info on how to downgrade)<br>

== 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).

=== Patch/Firmware Body Decryption/Hashing ===

The following is all theoretical and is intended to discard possibilities about modes of operation used by aes when decrypting body of firmware/patch

We know that:

* Two key expansions are used before applying crypto on body (one probably for hashing. the other for decrypting with cbc)
* Encrypt is used when applying crypto on body TopHalf (forward ttables) and Decrypt is used when applying on body Bottomhalf (inverse ttables)
* Authenticated regions uses a form of what seems to be some ECB with tweak xoring (as graf once said about XTS)
* XTS was introduced in 2007 and SysCon from ps3 exists for far more time than that (2003)
* XEX is a close relative of XTS that was introduced in 1984
* PS4 uses XTS for Authenticated Regions or SNVS (with sector size of 0x20 being used. is this even considered safe?)
* 4 regions can be controlled for DPA and they are: 0x2790 (size 0x20) (FFs), patch header (most notably at offset 0x4 of header size 0x10 and 0x30 size 0x10), patch body tophalf(+0x40) and patch body bottomhalf(+0x50)
* here are the DPA bytes for each of the controlable sections:
* 21 06 23 DC A2 98 99 4D XX 87 F8 40 FC 48 1C BF (section 2/FF's from 0x2790 on DIA-001)
* 21 06 23 DC A2 98 99 4D XX 87 F8 40 FC 48 1C BF (section 2/FF's from 0x2790 on DEB-001)
* 16 32 47 79 C3 2C 47 D3 2B 39 CA B5 83 41 0E D5 (section 3/header from DIA-001 patch content)
* 7B FC 27 CD D5 9A 05 09 3A DF E4 75 BF FD 03 1A (section 3/header AA from DEB-001 patch content)
* 92 4A 87 88 20 59 6C 49 9F 0E 7D 77 2F 38 4C FC (section 3/header DD from DEB-001 patch content)
* 7D C6 3B 3B 69 DF 67 4C 94 D7 D4 A8 E0 F8 5B B2 (section 4/body from DIA-001 patch content/tophalf/forward)
* 73 XX F0 3D XX 9A F0 92 4D XX 62 DA XX 48 3C DB (section 4/body from DIA-001 patch content/bottomhalf/inverse)
* 49 1F 7B 0A 48 BD 79 33 4E 16 89 F6 B0 25 86 48 (section 4/body from DEB-001 patch content/tophalf/forward)
* 14 4D F1 D3 21 B6 17 46 60 81 42 E5 02 C9 07 66 (section 4/body from DEB-001 patch content/bottomhalf/inverse/PROPER)
* some bytes are considered "weak" bytes and should be bruteforced in the eventuality these keys fail
* another possibility is that both the header and the body are hashed and then decrypted, using for example, cmac and cbc
* since key expansions take 10 "hills" in the analysis, it should be safe to assume that AES-128 is used(because it uses 10 rounds).
* 6554cff202c3bfdd9740901070b705bf :  correct md5 for patch content we are trying keys on (DIA-001)
* 4875ad06a1499cc516a0d4d92e595794 :  correct md5 for patch content we are trying keys on (DEB-001/DIA-002)
* trying a different header/body patch content from another similar board will result into failure of decrypting body, which means that the header is checked for authenticity and that the header hash is NOT in the header
* altering the patch header doesn't cause the patch header dpa bytes to change (a test was done with 4 bytes and the result was 16 32 47 79, which matches the other patch dpa recovered bytes)
* there are in fact not 4 but 5 aes sections. the last one seems to be body related, as changing the body even one bit makes the last aes section disappear.
* section 2 is divided into two sections, corresponding to TopHalf and BottomHalf of patch area.
* TopHalf uses forward ttables/sbox. BottomHalf uses inverse ttables/sbox
* TopHalf is ONLY the very first 0x10 bytes AFTER the header and into the body (corresponding to 0x40 in header size 0x10)
* BottomHalf is the rest of the body itself.

== 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 0x20 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 0x40 bytes probably are IV + HASH + update infos. probably the algorithm used is AES.
* algorithm used is aes 128 cbc on the body (iv is at + 0x30)

* replace 4 dots with soft id in decimal form, xor with 0x140 key and with cipher patcher key and encrypt with master patcher key to obtain cipher master key for that soft id

* replace 4 dots with soft id in decimal form, xor with 0x140 key and with hasher patcher key and encrypt with master patcher key to obtain hasher master key for that soft id
