Use this update to install system software version 4.73.
Always update your PS4™ system to the latest version of the system software.
To locate the model of your Play Station 3, look on the back of the system and locate the bar code sticker.
Underneath the bar code you will see the 11-digit serial number followed by a model number which begins with “CECH”.
So with the explosion of the Play Station 3 scene there have been a plethora of questions pertaining to the PS3 and downgrading.
So with that in mind I gathered all the information together in one convenient post that will help you find out the answers!
- Thanks to jbc for testing and King Dong for the icon :) - Now it works on PS3 fat. Download (295.14 MB) unpack and put it into the root dir of usb disk; 4. PNG – Updated for v2.0 - – Updated for v2.0 - Makefile – Updated for v2.0 - Progress bar and 128M bootmem fix.
Now your ps3 will update and restart to 3.55 rogero CFW.
T the firmware should say 4.25 however the firmware installed is 3.55, the 4.25 is just a version spoof so the firmware runs newer games and eventually can connect to PSn.
I personally move it into the C:\programdata\microsoft\windows\start menu\programs folder so that way it is available to all user accounts via the Start Mene.
