If you have a PSP-3000 series, this is currently impossible

If you have a PSP-2000 series without the TA-088 motherboard, then download a downgrader

I accidentally upgrde my psp, all the game inside memory all gone, how to downgrade it back


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/

How can i downgrade my psp version 6.30 ofw to 5.50 gen-d3.without using any pandora battery


I am afraid this is not possible, if it is a PSP 1000 or 2000 you would need a pandora battery. However if it is a PSP 3000 upwards there is no way to downgrade the firmware at all. Anything above firmware 5.03 is not possible to downgrade on a PSP 3000.

Hope this helps

XiaoFeiChong's Custom Firmware 5.02


If you want to upgrade, you must downgrade first. Any custom firmware upgrade cannot take place unless your PSP is firmware 1.5 or lower.

Chances are that you have a different firmware. If you want to get a custom firmware and downgrade, it is a very complex process that I do NOT recommend if you do not know what you are doing. It is very easy to ruin your PSP during the process. If you are still interested, research "Pandora's Battery" and other downgraders. It is a very long process too long to be explained here, and there are many guides online.

If you miraculously have a PSP that is firmware 1.5, I recommend getting firmware 5.00 m33-4 instead, as it is much more stable. Don't attempt anything unless you understand the consequences of possibly ruining your PSP.

Sorry if I scared you...

Frozen psp


Hi davidjuarez1,

You can downgrade/upgrade the firmware of your PSP. Visit pinoypsp.com or check any website that can guide you on how to properly flash your firmware to fix issue. Frozen PSP is usually a firmware issue, upgrading/downgrading it solves the problem.

Thanks,
Marvin

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. ^-^
