Can i downgrade my psp 3001 6.37 OFW


It is possible to downgrade the software on a PSP, but it is relatively difficult and voids your warranty. Also, it may harm your console, so before you decide to do it be sure that you understand the process and that you are willing to accept the potential consequences.

The first thing to do is determine what version of the operating system you are already using. To do this, go to "settings" in the main menu, then select "system settings," then "system information." Write down you version, as what version you are running will determine how you are going to downgrade.

After you determine what version of the operating system you have you must find an appropriate downgrader and follow the instruction given by the developer. The first thing you should do when trying to find a program is to find one that is specifically designed to downgrade your system from your current version.

However, if you cannot find one, or you don't trust any of the downgraders for your version (remember, if something goes wrong your PSP could be damaged, and your warranty will now be voided) there is a one-size-fits-all tool called "Pandora's Battery," which can be found at http://www.noobz.eu/joomla/news/unbricker-for-all-firmwares.html

Pandora's Battery is a good utility, but it isn't perfect. I recommend using it only if you cannot find another program for your specific version that you trust and understand.

After you done all of this, be sure that you understand what the program you chose is going to do, and what you need to do to make it work. Every program is different, and there are tons out there so I can't give you detailed instructions on using your downgrader, but if you don't understand it, don't use it.

I know I have already said this before, but it is important so I will say it again: doing this will void your warranty and may harm your system in a number of ways. Be sure that you are fully committed to downgrading, that you trust the program you are going to use, and that you understand the program before deciding to follow through with a downgrade.

Please let me know what you decide to do and how it works out. Also, if you need any additional support, feel free to leave a comment and I will get back to you as soon as I can.

I CAN DOWNGRADE MY PSP 3000 VERSION 6.35. TEACH ME HOW TO DOWNGRADE MY PSP TO VERSION 5.60. PLEASE HELP ME


There's a way to downgrade it now. Datel released a new battery called the Light Blue Tool. Similar to the previous Datel Tool battery, it puts the psp 3000 into service mode where it can be downgraded.
If you have a Magic Memory Stick, then you should be able to downgrade just like you could with any other psp...

Please need help to downgrade my psp-3000 to lower version for me to play games in memory stick.


if your firmware version is 5.03 or below it can be downgraded, if it,s above that it can not be downgraded as on now because the cracks available works only for version 5.03 or below. there are plenty of tutorials in the net if you want to downgrade your psp by yourself or you can bring it to a game shop which offer downgrade/upgrade or modification of psp.

GAMES FOR PSP 4.05


You need a pandoras battery + magic memory stick. Look on google, there are a million guides. This downgrades it to version 1.5, and then lets you add custom firmware.

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
