As I said you only need to do this if your psp if out of warrenty. I purchased mine second hand and had no warrenty.

Also at least for me this was a complete fix, not a way to rig it like the turning off the power, which may not work at all. I was doing that but after a couple weeks nothing would make it work again.

I would also venture to say that some people will not be able to use this at all if the wireless card has burned out completly from the shorts.
