here you go people here this is how you fix this error. after 2 days of trying to fix it i finally found a way to fix it.
1. remove all cd's,memory or anything you have connected to the ps3 on the usb's
2. turn on your ps3 from the back switch but leave it with the red light on(on the front).
3 now press the power button (where the red light is)and hold it, you will heard the initial single beep then you will hear a second single beep after that you will hear a double beep. when you hear hear the double beep release.
4. a menu with 6 option will appear. select option #3
5. when the ps3 comes back up. repeat step 1,2&3. but now select option 2
6 congrats you fix the error.
this will not erase any of your data(game saves trophys or downloaded content) it will only reset your user NAME(ex. user psfreak will reset to user1) all you have to do is rename it
