Project: Service Mode PS3 Arrives, PS3 Dev Work in Progress

Sponsored Links
275w ago - We finally managed to obtain a fully operational Service Mode PlayStation 3 system, so PS3 Dev work is in progress. As it came a few days ago, we have not had too much time to play with it yet, but will soon!

We did some work on one from flurix a while back, but alas, the unit did not function fully. Luckily, this unit we got works perfectly.

For a little background, it is a CECHA00 unit, which makes it a 60gb Japaneese PS3 model, first generation - full of backwards compatability, card readers and WiFi!

It appears to be a returned unit, as it was packed in a CECHE box, and had a false CECHE serial on it. From what we know to date, the first thing that happens when a unit hits Sony is to be reset into PS3 Service Mode via the PS3 USB JIG.

After this, the serial number on the back is scanned. We assume at this point they realized it was false, and sent it back, not repaired. Since it was sent back, it was still, luckily, in Service Mode - letting us obtain of it!

Our project goal is to be able to turn this unit into a full blown PS3 Test/Debug unit, as it would help if everyone had access to a development unit in order to fully explore the PS3. Of course putting a retail PS3 into a Service Mode console is another beast to tackle before that happens.

The PS3 Service Mode Systems do not utilize a hard disk drive, they totally fail to detect it (as we know) so installing a PUP the normal way is out of the question (it fails).

However, there is another way to install a PUP. We had time to briefly experiment with some PUPs, and at the moment a FULL Debug PUP installs perfectly, but fails to boot. We believe this is due to the Core OS package in the PUP.

With a little creative trickery (that will be detailed in a later post) on the PUP itself, we were able to get the Service Mode unit to install a Hybrid Debug Firmware, just like XVISTAMAN2005's PS3 HDD swap method that Sony later blocked.

We can use the same creative trickery to downgrade the unit as well, however, the issue becomes that the Core OS is retail, and has to be the same software version. This is where we are at after a few days with the Service Mode unit.

We are currently looking into ways to bypass this one last flaw - and after that, we may be able to successfully downgrade units, as well as install Debug Firmware on them.

The next step is to install hardware to facilitate the dumping of the NAND. This will allow us to change the firmware, then dump and compare the NAND images to see if the Target ID in the EID changes - if it does, this method will prove to be very, very useful!

Good news to end the year! Sounds really interesting. I wish you guys luck and hopefully it will work.

Maybe this will get the ball rolling, never stopping before the final goal.

How cool would it be if this lead to a nice easy way to downgrade retail ps3's / install custom firmwares etc.

It'd be great - the best bit would be the VERY RED Sony faces
All that hard work keeping it secure, only for one of their own Techy's to drop the ball

Sweet, keep up the great work CJ

PUP is a PlayStation Update file. It contains the firmware and a TAR file including many other PKG's and an encrypted XML file (I think there's just one)

This is amazing news though. I'm REALLY excited to see what this brings. When the PS3 finally falls, I'll certainly hack my system.

First of all congratulations on obtaining this.

Now I have two bad questions so please excuse my ignorance...

1 - What is a PUP?
2 - Does this mean you guys previously did not have a "full blown PS3 Test/Debug" unit?

How can you set a console back to the original state? You have to use the USB JIG?

Because if you can do without maybe you can backtrack to where the status is enabled/disabled?!

So the idea could be setting it beack to original state (if possible) and track what's going on (so you can reverse this process in retail PS3s).

Just an idea. Possible?
