Happy 4th of July! PS3 TEST Downgrade PUP's in the Wild!
First off, we would like to wish all of our American visitors a very Happy 4th of July 2008 today!
But for more explosive news (who doesn't love a pun?) we recently received two special PS3 PUP files from a VERY nice guy. As pictured below, they are PS3 Debug 1.00 (65.5 MB (68,765,224 bytes)) and PS3 Debug 1.50 (72.2 MB (75,762,080 bytes)).
These PUPs, which are the special downgrade PUPs, allow a user to downgrade their PS3 TEST from any version down to it. For example, with the 1.00 SPECIAL Downgrade PUP a user can be on 2.40, install it, and after a reboot be on 1.00!
1.00, which lacks just about every feature but ON/OFF functionality, will then let us upgrade to any DEV firmware above it.
Which brings us to 1.50... Through examining numerous Sony documentation recently, we have read that in the 1.60 Firmware the PS3's kernel memory and user memory are separated, leading us to believe that the kernel memory before hand had much more relaxed access permissions, if any at all.
The current theory (soon to be put to the TEST [another pun] by our resident PS3 Devs) is, using a lower Firmware console to peek around what we can access of the memory, and we might just get lucky! ;)
