188w ago - Developers at DemonHades have located and mapped the JTag Port on a PS3 Blu-ray drive board today.
To quote, roughly translated: I found the JTag port for the Blu-ray Reader on the PlayStation 3. Last night after finishing the research meeting I went looking for information about BD integrated reader.
In and looking at the information that I found on the back of the plate reader I saw that there is no connector terminals, these terminals belong to a connector which connects 'something' via terminals and through the Internet I found the points used in a JTag, including the TDO, TDI, TMS etc.
Originally developed for printed circuit boards, it is currently used for test of submodules of integrated circuits, and is also useful as a mechanism for debugging embedded applications, as it provides a backdoor to within the system.
When used as a debugging tool, an in-circuit emulator that uses JTag as the transport mechanism allows the programmer to access the debugging module that is integrated into the CPU. The debug module enables the programmer to correct their errors and code logic of their systems.
There are consumer products that have a JTag port integrated, so that the connections are often available on the PCB as part of the prototype phase of the product. These connections can provide a simple way to reverse-engineer.
As you can see we have a door strike to try to get the firmware, decrypted data, and all that is able to control the Blu-ray reader.
The data from this integrated JTag will CXD5063GG-1. CXD5063GG-1 = ASIC / CPU - Video Decryption Device Sony Computer Entertainment Inc., CXD5063GG-1, 2005 SCEI, 120,748 0608HAL.

Last night i talked with CJPC, besides helping me he told me that he will test the JTAG port, i have received 1 private (message forum? i guess) of a lot of people who wants to help me with osciloscopes wih great precision to colaborate with this project.
So, CJPC told he will test the port too.. i highly doubt they knew it before (the port)... the only thing that is exposed in internet talks about the port or ((1))bus that conect the BD Drive with the PCB, wich also have TX and RX points.
Besides, I have a picture of the JIG used in S0ny's Repairing Station (they called SAT wich is the place who receives the PS3's in warranty) and they use the conector of the bus named early((1)) to do some test, even if we are talking about two diferent ports it interesting to know something about it.
Well, my spanish language skills are non-existent, but my side of the conversation entailed - if you know of a JTAG - test it. Hook up a scope/LA, see what kind of signal your getting, and attempt to JTAG the thing.
Which, we did already try - it does not work - but never hurts for someone else to try it - assuming you somehow have a super special BD drive that wasn't blown at the factory, but the odds of that - well, you have a better chance hacking into the PS3 with a string and a paper clip!
Still.. being able to back up a PS3 game would have a devastating outcome if not used properly *Piracy*.. Tho it would be great to be able to back up your games.. knowing the original BD would be kept safe as long as possible.
YEAAA..i for my self would run throuth the blocks.."NAKED" will screaming "Jala,Jala Imschi Jala" (dont know what that means)
Im not surprised about that sunny have blowen the JTAG ports on retail machines and i remember back to the beginning where we have discovered that the BD FW is also present in the PS3's FW.Ok we can swap packs of the fw and flash it back so we could get the hacked bd fw into the ps3's fw to mach the drives fw but..how to resign?With what key?Does any one have discovered the PS3 puplic key?
I dono belive that sunny after all this havy securing have put in a UNSIGNED fw for the bd drive.
And even some one have discovered the puplic key we dono need to know about it till it could be used to do nice things with it.
After all...does tmbinc screamed out the info about the JTAG exploit for the x360 without the knowledge to use it?Or have he released the news together with a vid showing that it could be used to altere the machine?
