I am trying to format my ps3 hdd and install system software using USB drive.I am trying to format my ps3 hdd and install system software using USB drive. Its taking me to a screen with message preparing to update..do not turn off the system. After preperation has completed the system will restart automatically. And the percentage started and it came up to 99% and now its stuck there. I have been waiting for 45 mins and its still processing. Is it normal. My file system got corrupted and i searched the web and found that formatting the hdd and reinstalling the system software will help. I hve downloaded the update system software version 3.31 and put it in my usb as given in the instruction trying to install the softwares. Then i formatted the system in safe mode. Then i'm trying to install the system software using USB and got stuck in this screen. How long does it normally take to update the system sofware. If this dosen't work please advise what can be done.
