Cant remember pin number and am locked out

i do believe you have burnt out the inverter within the system :( i dont have an answer for you on how to persue a fix but i do wish you good luck .......keep in mind these are very cheap new nowadays so dont pay a big amount to fix it if possible ok :)

Whilst trying to put a pin number on my phone i have accidentally locked it and my phone is now asking foe a PUK number however i bought the phone 2nd hand and dont know what details were used when activating the sim so i am having trouble getting accsess to the PUK number!! Does anyone know what i can do??

I bought 2 psp units model 3001 for my kids with original 5.03 version. I can upload iso/rar games to these psp. I wonder why your unit is 6.31. Version 5.03 is uploadable and can play iso/rar games using chicken software ( for upgrading 5.03 to 6.31 version) and gen-c software for activating the games.

make sure it is well connected into the power source and into the ps3.
if the does not work you psp may be broken
i hope im wrong but try that and let me know how that works

Try taking it to Game Stop OK?Your welcome

Use pandora battery and downgrade ur psp into 1.5 firmare, upgrade it slowly ( dun upgrade it up to 3XX directly).

That should do it. Happy gaming!!

ya i agree with ninjauk

This may be a number of problems. The disc might be scratched or damaged. Or there could be dust on the leans.

You say it's a second hand PSP? In that case, you may need to repare it. I'm not quite sure where to go to get repares. Sorry.

Have you inserted the game disc UMD into the PSP itself? You have to wait a few seconds after you turn it on before the game icon will be visible in the main menu screen before you can access the game. When it's active and you have the game icon selected press the "X" button to start the game.
