My psp used a 6.20 version.but when i update it into 6.37 version,i cant open my games.what i need to do to use 6.37 version.my psp is 3000


If you had custom firmware on your PSP, and upgraded to 6.37, there is currently no way to downgrade to the old CFW or to play any downloaded ISO files. You will need to wait until a new custom firmware is release or a down grade patch is available.

Games,Update, Version 5.02


The firmware/software 5.02 is official sony firmware, its can't load/play your iso game from your MS.. to load iso, You'll need install custom firmware on your psp, the latest cfw update is 5.00m33-3, You can find it by googling or see at my blog here!. how to create pandora - magic stick.

To change your psp from official firmware you'll need pandora - magic stick (latest update DC7 - 4.01m33)for downgrading and install cfw,because since high kernel released, cfwcan be installing from 1.50 OF fat(old model) psp.. and 3.60 for slimpsp as startingpoint.

When you have 4.01M33 you can update to the latest CFw 5.00M33-3.

Hopefully this help, Pls post back should you need additional information, and also Show your Appreciation, to help other USER.

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.

How to downgrade my psp ???


Dangers of downgrading
  1. Know that downgrading your PSP voids the warranty and can be quite dangerous to your hardware.
  2. Downgrading often requires upgrading: You can only use a downgrader that goes from one firmware version to another, so most users will need to update their PSP to at least version 2.0 (USA) in order to then downgrade it to 1.5 or 1.0.
Find your firmware
  1. Determine which version of the PSP operating system you are currently running:
    1. Navigate to the main menu on your PSP.
    2. Select Settings -> System Settings -> System Information.
    3. Look for System Software Version X.XX. Where X.XX is the version number of your PSP firmware.
    4. Now you will know which downloader and/or updater you will need.
      • Note that any version greater than 1.51 will prevent you from running Homebrew and other independent applications.
Use the tools
  1. Be aware that your firmware updater and associated tools are located on the Memory card.
  2. Know that there are many tools to downgrade your PSP, depending on the version number of your firmware:
    1. Version 2.0 and 2.01 can be downgraded with Easy Downgrader.
    2. Versions 3.0 to 3.03 can be downgraded [here]
    3. Search Google for other downgraders.
The .tiff image hack
  1. Be aware that the hack below is dangerous. The developers who first found this hack bricked-up (destroyed) 6 PSP units before they got it working. A single miss-step can brick your machine and make it the most expensive coaster available. Please use at your own risk. These instructions will, however, technically allow you to downgrade any PSP that can display .tiff images.
  2. Know that this process is for downgrading from 2.0 to a lower version. If you have a higher version you will need different software, and if you are running 1.51 or 1.52 you will need to upgrade to 2.0 before you can downgrade to 1.5
  3. Download the original 1.50 EBOOT updater, version 1.5
  4. Download MPHDowngrader. Be absolutely sure it is version 1.0.0.
  5. Connect your PSP to your PC via USB cable.
  6. Go to the directory /PSP/GAME/ on your memory stick.
  7. Create a sub-directory named UPDATE which must be in uppercase.
  8. Obtain the EBOOT.PBP file from the updater.
  9. Copy the downloaded PBP file into the UPDATE directory.
  10. Download the MPHDowngrader and unzip the program.
    • Inside the package you will find a Photo folder with an image inside named overflow.tif.
  11. Drop overflow.tif into your /PSP/PHOTO/ folder.
  12. Place both h.bin and index.dat in the root of your Memory Stick.
  13. Disconnect your PSP from your computer and plug in the AC adapter.
  14. Navigate to Photo and then Memory Stick via the PSP's menu system and start scrolling down through your photos until you reach the overflow.tif picture.
  15. Everything will freeze, the screen will turn black and fuzzy white text will appear.
    • If your PSP freezes without going to this black text screen, then hold the power button for about 10 seconds until the PSP shuts down, then hit the power button again to start it back up. Repeat this step until you get that black screen.
  16. Hold the power button for about 10 seconds until the PSP powers off.
  17. Hit the power button again. Your PSP will start up.
    • Navigate to your System Information, and you'll discover that your PSP thinks it is running version firmware 1.0. It isn't, gthough, and you cannot yet run Homebrew.
  18. Navigate to Game -> Memory Stick, hit the X button, and navigate to the 1.5 updater.
    • Make sure you have your PSP plugged in or the upgrade won't work.
  19. Click the X button and update like you normally would. At the end of the upgrade you will receive an error saying that the upgrade failed and to contact Sony. Ignore this and again force your PSP to power off and reboot.
    • After the PSP reboots, you will receive an error screen in multiple languages. Find your language and read the corresponding line. It notes that your preferences are lost and that you need only hit the O button to restore some default settings.
  20. Hit the O button.
  21. The PSP will start back up and you will go through the initial setup like the day when you first bought your PSP. Do so and then go to the system info pane again, where you will see that you are running version 1.5.
  22. Run homebrew at will.

[edit] Tips
  • For a new firmware version to be downgradable crackers first have to decrypt any new security or authentication measures, and then create a downloader. This can take some time and is a process of constant change as new versions are released. If you attempting to downgrade a fully updated or brand new PSP you will need to work with the latest version of the firmware, current version 3.5 in the USA.
  • Downgrade Your Psp to Version 1.5 just Using Your Psp Battery

[edit] Warnings
  • There are many web sites out there that will sell you videos or instructions, but beware, the information is available and the tools needed are free or shareware.
  • Do this at your own risk. This technique was created by modders and might not be 100 percent reliable. It may also void the warranty for your PSP.
  • Anti-virus scanner and software will often identify PBP as potentially malicious. You may need to temporarily disable these security measures to obtain the updates.

[edit] Things You'll Need
  • PSP
  • USB cable
  • Microsoft Windows ™ computer with usb support
  • Internet connection

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. ^-^
