Depending on the PSP Model 1000-2000 you can downgrade your PSP using Custom firmware by forming a MMS using RainsUltralite and a Pandora's battery. Custom firmware equivalent to the official firmware can be determined by the games played. Most recent games require updated firmware. This site should help you with all the software necessary to downgrade or modify your PSP. http://pspslimhacks.com/rains-ultralite-mms-maker-for-500-m33-4/

Hi i want to ask how to downgarde psp 6.20 to 5.50 without pandora battery please help me in that...thank you


Hi

You can downgrade your psp without a pandora battery but you will need a Lumines game hack,Follow these steps to do so.

Download the 5.50.pbp file. Rename the 5.50.pbp file to "UPDATE.PBP." Connect your PSP to your computer with the USB cable and select "USB Connection" to place the PSP into USB mode. A window will appear on your computer and you will be able to see the PSP memory stick files.

Download the downgrade pack. Open the "MS_ROOT" folder from the downgrade pack. Right-click the "PSP" folder and click "Copy." Go back to the PSP memory stick and right-click it. Click "Paste" and "Yes" to overwrite the data.


Right-click the UPDATE.PBP file that you downloaded in step one and click "Copy." Open the "PSP" folder on the PSP memory stick and you will see the "GAME" folder. Open this folder to reveal the "UPDATE" folder. Right-click the "UPDATE" folder and click "Paste" to transfer the update file to your PSP memory stick. The downgrade pack and 5.50 update file are on the PSP memory stick. Press the "O" button to safely disconnect the PSP from your computer.

Insert the Lumines PSP game into the PSP drive. Select the game from the PSP menu to start. Press the "Start" button when you get to the Lumines start screen. Your screen will blink red and will turn completely blue. You will be brought back to the PSP screen. It is important to not press any buttons before you get to the Lumines start screen.

Go to the game section of the PSP menu and you will now be able to see the "x.yz update" application. Select it with the "X" button to start it. Press the "X button from the main menu to start the downgrading process. Press "X" again to reboot the PSP when the downgrade has completed. You have now downgraded your PSP to 5.50 firmware.

You can downgrade your psp from 6.10 with a service or pandora battery. This will let you back up games you already own and run them from the memory stick.

Updated to 5.51 and all games are not available


Nothing could happen now because once you've update your psp with v5.51 it will not downgrade and you can only play UMD games or demo.

Cannot play copied games in psp's memory stick after updating


Hi Aneeshameeda

I think the best solution is to downgrade your PSP system software to the original version and check if your games load. What might have happened is that the firmware software that was on the PSP was downgraded to play copied games, and now you've changed the firmware to a newer version and that is why your games won't load. You might hac=ve to get your PSP downgraded again to play the games from your memory card.

I cant play games from memory


Hi kalfan

What happened was that when you downgraded your PSP to -play game from your memory stick, that version was loaded onto your PSP for a reason. What you did now is install the latest firmware and that disabled you from playing games from your memory stick. You might have to get your PSP downgraded again with the older firmware version.
