I have the verson 4.5 system software but I dont want to go out and buy anything any tutorials?
you should state what model slim youve got, + if its on the latest firmware you have to order a E3 or some other sort flasher to downgrade the firmware
You can downgrade your PS3 with a E3 flasher to 3.55 if your PS3 model is below CHEH2500 or made before 2010. That's the only option you got unless you have to buy a 3.55 PS3 too.
