Re: downgrade psp firmware 5.02
Someone will have to run the flash program to get you back to M33. Pandora battery and Magic stick with M33 flash on it. Most homebrew and programs will not run on any M33 version above 3.9. New UMD games from sony will have the latest firmware and the children will usually run the firmware upgrade to play the game. It will allow the new UMD to play, but the Sony Firmware will write over the Custom M33 firmware and you will not be able to run the games on your Memory stick.

Download MPH Downgrader and Firmware version you want(e.g 1.50) to the Windows-based computer. Connect the PSP Slim to the computer's USB port using the USB connector. Transfer the two programs to the main folder of the PSP Slim. Disconnect the PSP Slim from the computer's USB hub when the transfer is complete.
Turn on the PSP Slim. Go to the Settings/USB Connection in the Home menu and select the EBOOT.PBP file in the PSP\GAME\UPDATE update folder. Extract the MPH Downgrader zip file to the root folder of the PSP. Click OK using the X button if you are prompted that this will replace some files.
Go to Photo/Memory Stick in the Home menu. Wait as the screen goes black and numbers appear. Wait two minutes and then press and hold the power switch until the PSP Slim turns off. Release the power switch.
Wait as the PSP Slim turns on and reboots. Go to Game/Memory Stick in the Home menu and select PSPS Update version 1.50. Press the X button to start the update.
Wait as the update finishes and presents an error message. Press the O button to restart the PSP.

You CANNOT downgrade to an earlier custom firmware or software sit until a newer custom firmware is available. You will have to make a Pandora Battery and a Magic Memory Stick. Basically you have to open up a PSP battery and cut a certain peg. The magic memory stick is alot easier and doesn't pose a threat to the PSP. Watch a tutorial on youtube for the Pandora Battery so you don't stuff up, there is a different method for the PSP Slim battery
its because the psp version where change that's why the psp stops working on games only psp version's with m33 can play download games and other might depend on your umd games...so i suggest that you downgrade your psp to the original version of the psp that you have so your son can play the games that he want. hope it helped.. send me a message for more concerns...ty
if you have downloaded the firmware from the internet, that is really not advisable. it would be best to go the nearest gaming zone for updating firmware.
some firmware are not compatible and not updated. downgrade your firmware to a more stable firmware.
HELLO! There's no need to downgrade ur PSP. If u have upgraded ur PSP from the official site and a official firmware has been installed on to ur PSP, it won't execute games(ISO,CSO) from ur memory stick. It will only run games from the UMD. If u want to run ur games from a memory stick u have to install a CUSTOM FIRMWARE. Try www.psp-hacks.com these guys have many softwares on their site. Dont worry its not that hard to put a Custom firmware onto ur PSP.
hi your previous psp version is 3.80 m33 if yes your using custom firmware that why you can play game to your memory stick the problem is you upgrade your psp firmware to sony official firmware 5.01 you reinstall your firwmware again using custom firmware like 5.00 m33-3 cfw below with m33 or OE
