Re: cannot play games with vertsion 3.71 m33-4

? You bought the firmware? Its supposed to be free. I think you got ripped off. It automatically updates if you connect the psp to a wi-fi network, and you can also update it by connecting the psp by usb to your computer.

The game in psp memory stick can play on the first psp only


Check if they both have the same firmware version. Most of the new games are not compatible with the older firmware versions.

Downgrading my psp 5.51 to 3.70 m33

Sorry Ryan, you will need a service or pandora battery to reload custom firmware.

This will let you back up games you already own and run them from the memory stick.

You can create a pandora battery and the 'magic' memory stick from any psp already running custom firmware. You can also buy them online, and if you look in the local classified ads website where you live, you can probably find people offering that downgrading service.

I cannot run through the steps here to create your own, but tutorials are all over the net and sites like youtube.

Custom firmware

Earlier you have said that you were able to play games from memory stick and since you updated your psp firmware the didn't worked.
First Check your current firmware version . To do this go to
Settings > System Settings > System Information on your PSP . If you your version showing  for example 5.00 M33 you are still in Custom firmware. In this case you should able to play the games from memory stick. or else you memory stick is back... or you custom settings are wrong.

If its showing  for example 5.00 you are with Sony's official firmware. In this case you wont be able to play the games from  memory stick. From here to make your PSP play the games from memory stick you need to Downgrade your PSP. Only way to make this possible is through Pandora Battery and Magic Memory Stick.
So please check your version and let me know so i can guide you further. Also tell me whether your PSP is PHAT or SLIM & LITE..... or check the version of your PSP by removing the battery. Underneth it find some letters and numbers PSP-100x / PSP-200x / PSP-300x

Downgrade PSP from 3.80

It's impossible to downgrade your PSP from it's current version. I'm not quite sure why you'd want to downgrade, but maybe you should upgrade (If a version is available) again and see if you like that version better. ^-^
