NOOB HELP!

yesturday i upgraded my psp into new 3.95 firmware and now i cant play ISO games on my psp, it says game could not be started and the file icon is corrupted. What should i do for this situation?

Alright ma man, looks like you have a bad case of official firmware...

Answer these questions:

1.) Do you have a PSP slim?
2.) What firmware did you update from?
3.) Have you ever played ISO games on your PSP?

yes i got slim updated from 3.71 i played ISO games b4 but now i cant

Hate to rub it in, but how in the hell did you end up upgrading it?

I believe the solution is to get a Pandora battery for a Slim (Google it) and then proceed in running it and downgrade. Then install a Custom Firmware to play your games. Use the Search tool here to learn how to downgrade once you have a Pandora battery.

I have never had to do this, since I have never been in your shoes, but I am pretty sure people here know the ins and outs on how to do this.. good luck.

He's in for a hell of a ride...

Was your firmware 3.71 CFW or not.
