December 2, 2010 // 8:10 am - 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/

I wonder: since this allows 2.15 debug to be installed, can users then just simply upgrade to 3.41 debug as there console is now fully converted to a PS3test?

Certainly pity the devs who would have paid a fortune to get a real debug unit.

Anybody remembers the days of how RivaTuner was used to softmod GPUs

You can only downgrade with the original jailbreak right? If so I am still waiting on a psgroove hex for my teensy

Ok that's an acceptable reason. But guys don't forget: It was the 3.41.pup file used and every pup is signed with SHA1 checksum.

There for you couldn't easily use any debug pup file you want because then SHA1 will not match anymore.

That this pup will match the SHA1 checksum of 3.41 retail pup file is a little secred why.
