The file this PS3 Scener is talking about has a link posted on ModderExcess45's facebook page. I'd stay far away from it, the guys a known fake & I wouldn't doubt Ps3 Scener is a part of his little scam "dev team" along with the mini-me Jay Leno on crank kid in the YouTube video above.
This crapola? God I hate having to navigate away from PS3 News for stuff, maybe I'm just lazy
From FB: Since I won't be able to 'play' with the PS3 the way I want for a little while, here's some work to fittle with. (Bricks on 4.30) Installs on 3.55 and below with SEN Access. (And PUBLIC Keys for decrypt are there)
