How to Downgrade your 2.00 PSP

***h2o pete*** · 10-23-2006, 03:45 AM

Step 1: Download the downgrader from either here. Then make sure you get a copy of the original 1.5 firmware upgrader. I found my copy here.

Step 2: Connect your PSP to your computer via USB. On your memory stick, create a folder called UPDATE inside /PSP/GAME/ and place the EBOOT.PBP file from the 1.50 update inside this UPDATE folder.

Step 3: Unzip MPHDowngrader.zip. Drop overflow.tif into your /PSP/PHOTO/ folder. Put both h.bin and index.dat in the root of your Memory Stick.

Step 4: Disconnect your PSP from your computer and plug in the AC adapter.

Step 5: Navigate to Photo then Memory Stick via the PSP's menu system and start scrolling down through your photos until you reach the overflow.tif picture.

You'll know you've hit it when everything freezes and you get a black screen with a bunch of white text output.

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.

Step 6: Don't panic. Hold the power button for about 10 seconds until the PSP powers off. Hit the power button again. Your PSP will start up, and if you navigate to your System Information, you'll discover that your PSP thinks it is running version 1.0 of the firmware. It isn't and you cannot run homebrew (yet).

Step 7: 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. 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. Don't panic. Ignore this and again force your PSP to power off and reboot.

Step 8: After the PSP reboots you will receive an error screen that is scary and confusing because it is in multiple languages. Don't panic. Find the language you can understand and read the corresponding line. It notes that your preferences are fragged and that you need only hit the O button to restore some default-ish settings. Hit the O button.

Step 9: 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 rocking version 1.5. Run homebrew at will.

can i do it with 2.60?

hexitnow · 08-17-2007, 08:22 PM

No not with those files however u can downgrade 2.6 if u have an unpatched version of GTA:LCS. Or you can upgrade to 2.71 and not have to use a copy of GTA. Are you very familiar with the PSP.

im viewing and typing on my PSP right now. i dont have a big enough mem chip 4 2.71

hexitnow · 08-19-2007, 11:53 PM

you should its not a very big update file. even the 32 MB mem stick that comes with the PSP is enough for it.

Good tutorial I want to downgrade my PSP it used to be my computer geek brothers but since he was never into this kind of stuff he would just upgrade it when sony put a new upgrade out. My psp says its System Software is version 4.05 will this tut work? This psp is kinda old... would clicking on "restore default settings" possibly bring it down to its original software?

XboxMODnooblet · 05-02-2009, 08:10 PM

***h2o pete*** · 05-02-2009, 08:22 PM

XboxMODnooblet · 05-02-2009, 08:28 PM

Thanks, now I notice that making the magick memory stick dose not cost anything, but if I read those directions correctly I also do not need to buy anything to create the Pandora Battery as well right?

***h2o pete*** · 05-02-2009, 08:35 PM

You need a 1.50 PSP as well lol.

XboxMODnooblet · 05-02-2009, 08:37 PM

huhhhhh!? a 1.5? to make a Pandora battery and magik memory stick?

Why is that?

I have looked around... would I be correct to assume that if I want to make a Pandora Battery without having a 1.5 firmware I have to open up the battery?

You don't need a version 1.5 psp to make the Magic Memory Stick right? cuz if thats true I will just buy this.

I think you just need the 1.50 PSP to make the pandora battery, I don't think you need one for the magic memory stick so yeah you might as well buy a pandora battery
