I have valuable data
Hey Rogero, Let me give you an overview of my PS3's.
I have a PS3 Slim Model# CECH-2001A
I just Upgraded the firmware from Rogero 3.55 to Rogero 4.21v1
There was no bricking whats so ever and a speed in increase in the XMB
I also have a 80Gb Phat Model# CECHE01
The firmware on it is Cobra 3.55 and would like to upgrade to 4.21 but
I would need a CFW for Cobra, like Cobra 4.21.
Also If you noticed I have a Cobra Usb Dongle
So in other words It would be my pleasure to work for Rogero, just message me for futher assistance.
