So when I download to Official 3.55, should I do it in the Safe Mode Menu?
After/If I can get that to work, then which should I do?
Restore Default Settings
Restore File System
Rebuild Database
Restore PS3 System
Or All of Them?
you will have to go into restore mode if you do not know how to do this its..
1. Turn off Playstation 3.
2. Hold The power button down; The system will turn on and turn off once again.
3. Once the System has been shutdown, re-press you finger until you hear 2 consecutive beeps
4. When you hear the 2 beeps take finger off power button.
5. You will be promted to plug in your controller via usb and then hit the PS button
6. The Recovery menu will pop up.
Once thats done put the OFW 3.55 on your USB and restore it that should do it.
If you have a CFW installed it will not recognise your OFW or install it because as you said it is not necessary. and when you are doing the JB you are meant to wait until the PS3 turns on by its self.
I hope i have helped you
Tell me if this worked
