Videos: Debug Firmware on Retail PS3 via PS Downgrade Demo

Sponsored Links
211w ago - A few weeks back we saw a video of PS Downgrade in action, and today ANTONIOPS at Spanish site Elotrolado.net (linked above) has posted up some videos showing PS3 Debug Firmware v2.15 being installed via PSDowngrade on a 40GB Retail version 3.41 console followed by running a PS Store demo.

Normally PlayStation 3 service boxes require a proper downgrade PUP file, however, comparing the SHA1 hash of the released PUP confirms it contains nothing special (just the old 3.41) so there appears to be something 'interesting' taking place when downgrading via PS Downgrade.

To quote, roughly translated: The noise you hear when you turn on the PS3 is the reader who is half repaired.

The Debug firmware I've installed the firmware downgrade PSDowngrade 3.41 to 2.15 Debug.

At the moment can only run signed code, such as a PS Store demo.

Those interested can check out the videos below!

Finally, in related news comes a brief guide from gliitch on installing PS3 Debug Firmware v1.0 on a Retail Console:

[ROoT] Level2Diag.self(1)/UPDAT.PUP(DEBUG1.0)

Put your PS3 into service mode, then once its powered down, plug in your usb stick with the files. it takes about 4 or so minutes to complete.

Wait for it to finish, and then turn the PS3 back on O_0 and vollia! 1.0 Debug on a retail PS3. Now, there isn't much point in doing this as it doesn't really have anything on it.

You can update straight back to FW 3.41 via usb by [RoOT] PS3/UPDAT.PUP/

Hey i want to ask you to join our team. Noticed that you have some skills in case of payload moddifying is that right?
Maybe i have some ideas to get a full cfw done.

Send it to us or post it and we can do some tests with it. In worst case we will have it for future purpose in case that if some times it will be possible to change files from flash.

This is some interesting reading! cfwprophet - thanks for clearing that up!

I've been scouring the net for a decent-ish priced PS3 debug console and fingers crossed I might have it before xmas

At the moment it's like trying to play poker without and cards...

Yes, I think a very important part of Hacking the PS3 is to somehow get write access to the PS3s flash memory, hopefully a payload can achieve this, then we can start permanently modifying the XMB and the sky is the limit! For now the only permenant mods we can do are to the registry.

I already have my FTP app installed to network, I think thats where it belongs really as its certainly not a game.

P.S. I found after modifying install category (CB) in param.sfo I had to run the app once before it moved over to network category. Now it appears under network every boot.
