- 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.

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