Psp games disappear when updated to 6.10

download the last update and it should work or try download the same game with the update already done

your psp is bricked

"Brick" means corrupting your Firmware, the system that makes your PSP run. Bricking can be caused by either "interrupted update of firmware" or attempt to install "PSP Hacks" also known as Jailbreaks or Custom Firmware (CFW).
Some PSP Models can be revived when bricked by using a system called "Recovery Menu" which becomes available when the PSP was running a CFW before it bricked. Another way of unbricking a PSP including those that runs Original Firmware is using Pandora Battery and a Magic Memory Stick.
However, there are PSP MOdels that cannot be unbricked. These are the PSP 2000 Slim that have the Motherboard TA088v3 and other higher end. The worst PSP Motherboard is the TA088v3 because once bricked, PSP becomes a lovely paperweight without game functions and possibility to be revived.

just unlock it then it would work

Your need to download the ChickHEN and CFW GEN-C 5.03 update from the internet and install it in the memory stick of your PSP.

and follow the instructions carefully how to hack your PSP.

ask in any game shop how to do it

Do you have a rock band unplugged .iso? If so, it has copyright protection, and deletes your game folder so that the games disappear. To stop this put anything into your GAME folder.

take off the battery and try again. If this doesn't help then the copy of the mlb game is defective.

Or you can just update your PSP through your computer (if you have internet)

Here's a link.

u need to find a MP4 game and put it into e folder tt said MP4.. but is hard to find those game.. if u find some.. pls let me noe.. thanks..

This happens when you have a dirty psp game loaded, perhaps it needs cleaning? It can also happen if somehow the system files have become corrupted, if this is the case you must reinstall the PSP software or try updating it by connecting to the internet with your psp and going to the update function.
