( If in wrong section move to right section, thank you )
Well today, I was experiencing problems with my PS3 Not signing it and stuff you name.
I have found a key to fix this.
1 Turn you PS3 Off.
2 Hold the PS3 Button/Motion Sensor until you hear 3 beeps. ( not including the first one )
3 Get your PS3 USB Cable and connect it to your PS3.
4 Now it will come up with a Menu
Restart PS3
System Update PS3
Reformat PS3
Restore Default Settings
Restore System
Now just click on the one you need and it should it.
Thank me if I Helped
