Hacking Ps3 Test unit Fw 4.81

[Alexas]

Hey Guys,

I was recently given a test unit from a friend which is runing 4.81 firmware, iv searched around for 4.82 Dex firmware but from what i can see its not really publicly released,
iv tried using the 3.55 downgrade pup but it gives me an error saying that its not usable on my system,

im kinda at my whits end right now

Its a phat ps3
DECHA00A
300gb
backward compat
all debug options are there
i honestly dont know what to do at this point
any help would be amazing thankyou

You can download the d-rex version of rebug 4.82 and install that.
