PS3 Debug / Test Firmware 3.72 Patch Update (10.93MB)
Similar to the
3.72 OFW Patch from the recently released
PS3 3.72 (Retail) Firmware, it appears Sony is now offering compressed patch updates for PS3 Debug / Test console users.
As always, it's important to note that these PS3 Debug / TEST updates will currently NOT install on a retail PS3, and so it is intended for examination and comparison purposes only unless you own a Dev unit.
For those curious, running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported. (8002F029)
the System software version 4.41 is what i have. And I have an external hard drive which is 500 GB. I might be being thick is there a process on need ...
Thanks for the update 
And if your referring to me "This guy can see in the future," then I do agree it dose seem that way going by some of my posts five month ago when I said how I thought some things will turn out. And they have.
"The people in history who said "never" are rarely, if ever, remembered..." thats why people like me don't ever use their real name, and don't wish to be remembered.
In fact in the 25 years of using the net or computers I have never used my real name or address. lol. so No I don't wish to be remembered. nor found. lol
Because as I understand this, its just not passable unless the master base firmware has been leaked or created giving you the option to install the original firmware that said unit was shipped with, then upgrade back up to any ver you like.
The pups that we install are upgrades patches, hence the small size of only 180 megs ish, the full flash can be anything up to 250 odd megs in size depending on what unit it is, and it dose use some of the drive for storage, as you may or may not know.
So if you wanted to downgrade from 3.56 to 3.55 you would have to reinstall right back from the beginning to replace what was removed and locked in 3.55 and 3.56 and above.
Once you go past the 1st release of 3.55 it is game over, because home-brew will not work past 3.55 nor will blue rays on modded firmware. I believe that apples to debug and rebug as well, So backed up games is over if your over 3.55. Sad but true!
