Hello ps3news! I just picked up a used PS3 (model CECH-2002b) running firmware 4.25 and obviously I wanna jailbreak this bad boy. I've read that I need to downgrade it to 3.55 first which I'm totally willing to do, I'm just having trouble finding some particular info about the hardware required.
I performed my own jailbreak back when 3.41 was the current firmware and I used my PSP for that. Is it still possible to use the same PSP to downgrade my 4.25 to 3.55? I figure that'll save me a lot of bother waiting for new hardware to arrive in the mail.
