Question about Sony PlayStation Portable (PSP) Console

PSP Firmware Does anyone know of a way I can downgrade the firmware for my PSP? I've heard that once the firmware is updated to a newer one, there's no going back down to an older version of firmware.... I have a Slim PSP with firmware version 3.80 and would like it be version 1.50. Any ideas? Thanks!

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/

Psp3000 verson 3000 need downgrade now adn demos


very simple solution. why would sony want anyone to just have free games. its not in their business to just chop up free games. So that means you need to install the nesccary FirmWare to enable such piracy as its not legal.

First off I have a modded psp and its a 3000 series and I've done the nesccary steps to mod it, but i dont do it to play psp games as i buy my games to support sony, the only reason mine is modded is so i can play my psone games i own and to play other things like cheat enablers for psp games

If you have a psp then step one is out of the question, my method involes buying a psp with prior knowlegde of what firmware it has as this makes a huge difference. you cant downgrade psp 3000s [not yet at at least trust me you will wait at least 1 year or even more for downgrades above 5.03] If you purchase a psp 2000 or 3000 with FIrmware 5.03 or below then its is possible to mod it.

then just use these programs and you its pretty easy,
programs! ChickHen for 5.03....Official firmware update 5.03[ if ur psp is below 5.03 then u need to update it 5.03, just place the eboot file u get in a folder named UPDATE in your psp/game section on your memory card] then use gen a firimwares, just search for 5.03 gen a ltr

PSP WON'T BOOT AND LOST FIRMWARE - NEED TO RELOAD & HOW


Reloading the firmware into a psp what won't start is called 'unbricking.'

I know that a pandoras battery will unbrick the phat psp-1001 model, but I have heard that it may not work to unbrick a slim. Since it's a paperweight now, it can't hurt to try, right?

You can create a service (pandora) battery and the 'magic' memory stick from any psp already running custom firmware. You can also buy them online, and if you look in the local classified ads website where you live, you can probably find people offering what they will call a downgrading service.

I cannot run through the steps here to create your own, but tutorials are all over the net and sites like youtube.

Iso/cso won't run to PSP version 4.20


You cannot play .iso or .cso files (or any homebrew games) on your PSP unless you have firmware 1.5 or a custom firmware. Any "off-the-shelf" firmware such as 4.2 will not support these types of files. They will just show up as "Corrupted Data".

You can go through the process of downgrading your firmware from 4.2 to 1.5, then from 1.5 you may upgrade to a custom firmware such as 5.00 m33-4. Doing so would require a good deal of technical know-how and a LOT of patience. If you do not want to risk ruining your PSP, do NOT try this. Research methods of downgrading such as "Pandora's Battery" and other firmware downgraders.

You were able to download games from the PSP website because they are programmed to play on the current firmware. Even if you were to (somehow) properly convert the .iso or .cso files to an EBOOT.PBP file, it would not run unless you have firmware 1.5 or custom.

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.

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. ^-^
