Quote (ConsoleDev):
For those who own PS3 Debug / Test consoles or are simply into collecting PlayStation 3 file leaks, recently PS3 Debug / Test Firmware 3.74 surfaced alongside version 4.00 from Sony's North American Press Web site.

If you didn't know, the address to their Press site is
 and Sony offers free access to all members of the press there using *SCEA* / *SC3APR* to login and obtain the latest press releases and related files.

Finally, keep in mind these PUP updates will currently NOT install on a retail PS3, and so they are intended for examination and comparison purposes only. 

We have 100% confirmed that 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)
