Editing Syscon Firmware

= Description =
The '''Syscon firmware''' (also known as '''sys'''tem '''con'''troller '''firmware''') is the software stored inside [[Syscon Hardware|syscon]]. Composed by the base firmware (not updateable in retail syscon models) and a optional patch that is applyed virtually on runtime on top of the base firmware<br>
The syscon patches (also known as system controller update packages) for retail PS3 models are distributed in [[PKG_files|PKG]] format inside the [[Update_files.tar]] of the [[Playstation Update Package (PUP)|PS3UPDAT.PUP]]s. Syscon patches appear to always be 5KB (5376 bytes) in size.

= Update procedure =
The PS3 firmware installer PUP's contains a collection of syscon patches for all the different syscon's chips used in the different motherboard models. The ps3swu.self (system updater) checks the syscon [[More_System_Information|SoftID]] and installs the compatible patch accordingly (via updater manager ss service).<br>
The non-retail PS3 models with syscon [[CXR713F120A]] don't have patches, this special syscon model with the "F" product code (that seems to indicate that is fully flasheable) allows to overwrite the base syscon firmware through the [[Communication Processor]]

The screen [[More System Information]] allows to see some details related with syscon. The syscon firmware version can be derived from the SoftID, and additionally if there is a patch installed the PatchID displayed in the screen contains both, the syscon firmware version and the patch version. Note also that there is a direct relationship in between the PatchID displayed in the screen and the patch filename. The syscon UART commands also displays some info related with the base syscon firmware and the patch

Some examples from syscon UART:

* Note: For the weird bogus update ONLY: FFFFFF37 (Alignment Error?) (Trying any data size between 0x41 and 0x4C bytes)
* Note2: v0.6.14c4 is the bogus update (only update with a weird header)
* Note3: setting data between 0x40 to 0x4C to zero in bogus update yields error FFFFFED0

=== Content Data Patch (encrypted) ===
Packages can be extracted with the unpkg tool. Extracted content of the updates appears to always be 0x1000 bytes (4KB).

The following is all theoretical and is intended to discard possibilities about modes of operation used by aes when decrypting body of firmware/patch<br>
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) -> 210623DCA298994DFE87F840FC481CBF  
* 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) -> 210623DCA298994DFE87F840FC481CBF  
* 16 32 47 79 C3 2C 47 D3 2B 39 CA B5 83 41 0E D5 (section 3/header from DIA-001 patch content)
* XX XX XX XX 7B FC 27 CD D5 9A 05 09 3A DF E4 75  (section 3/header AA from DEB-001 patch content) -> 6E9CE7C57BFC27CDD59A05093ADFE475
* 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) -> 6B3583DA1AA6B49106E1641178EE68C8 (inverse ttables)
* 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.
