157w 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:
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/

1) yes, got RSOD plenty of times on my PS3 while messing around flashing different versions of files to dev_flash.Also sometimes it doesnt even show redscreen to just a blackscreen crash on bootup.
2&3) yes, using service mode payloads for worst cases, and recovery menu for semi bricks it fairly easy to recover and reinstall 3.41 retail, I can't gaurantees in all cases but for example I have tested deleteting over half of dev_flash folder (vsh 85MB) and recovery menu was still working fine , some red screens require service mode to fix, some don't.
