Hacking Help identify ps3 cfw

[dust213dust]

Hello,

So today i got fat ps3 and it is on some kind of cfw. Can you help me identify it so i could search the right guide to install games..

Sys info said that its just 4.81
As i know nowhing can be done with this version so how am i on cfw or jailbrake or whatever it is?

Please see the image attached..

And whats this app o. The second picture

I think it is possible to install rebug 4.81 cfw over it. At least you could replace the PS3 hdd then install rebug 4.81 cfw.
