PS3 - FAT Can't figure out what i should do ?

Hello,

I made a thread yesterday,but it was my 1st post,and i don't know, why it wasn't posted.So i will make a new thread.

I have a FAT PS3 ,that i want to jailbreak ,just to play games , from external HDD or .iso that i find.

But , i saw different tutorials and got confused.The steps that i need is to install first HFW 4.85 and then OVERFLOW CEX ,but the overflow is forbidden and taken down ,another popular is REBUG (as i see) but again i don't see it anywhere.

So what should i do ?...
