6.60 Downgrade Tutorial

Post by Pawel » Tue Jun 12, 2012 9:23 pm

This tutorial will show you how to downgrade your PSP OFW 6.60, 6.35 or 6.31 to OFW 6.20.
I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT CAN BE CAUSED BY USING THIS DOWNGRADER.
This downgrader is compatible with PSPs up to Model 9g (PSP Go included).
To check what PSP model you have, download PSPIdent 0.75 here: http://www.mediafire.com/?pb9gccudpf8okc1
To install PSPIdent simply put the PSPIDENT folder to ms0:/PSP/GAME.
NOTE: You can only use PSPIdent if you already installed CFW on your PSP System.

1.) First of all, check what PSP Model you have to make sure your PSP is compatible. We don't want to brick the PSP do we? :)
(SKIP THIS STEP IF YOU ALREADY KNOW YOUR MODEL IS COMPATIBLE)

2.) If your PSP is compatible, go ahead and download 6.20 OFW and the Downgrader:
6.20 OFW PSP Go: http://www.mediafire.com/?yixdkkoaadm4scq
6.20 OFW: http://www.mediafire.com/?j0mhw8ms1u64tv9
Chronoswitch downgrader: http://www.mediafire.com/?jmvb5f9gn30265v

3.) When downloaded, extract Chronoswitch Downgrader folder into ms0:/PSP/GAME.
Then go into ms0:/PSP/GAME and make a new folder called UPDATE (Capital Letters) and extract the EBOOT.PBP from the 6.20.zip folder into the UPDATE folder.

4.) Safely unplug your PSP from the computer and start the Downgrader.
When you start it, it's going to say "Press X to continue" right after checking your firmware. Press X.
After that, Press X again to start the SCE updater and if the Downgrader worked successfully, 6.20 official update should load up.
Keep pressing Next until your PSP starts installing the update.

5.) When the update finishes, your PSP is going to restart and this is what should come up.

Don't worry. It's suppose to happen. Just press O to restore your PSP settings.

6.) And you're Done! :D

Thanks for the tutorial but I have some questions , they might sound noob (forewarning :). Here goes

1.) Can I downgrade my 6.60 pro b10 using this tutorial ?
2.) Is there a way to go back to 5.00 m33 or 5.50 m33 ?
3.)The above two without Pandora's battery ?

Thanks in advance!!

Did you use the "physical updater for TA-095" while updating to 6.60?

If not then there might be some internal error, which prevents your PSP from up-/downgrading.


Downgrading an 09g device to 6.20 is a stupid thing, by the way. Dont force a firmware that was not ment to be for your device.

Read it as many times as possible, usER's. Downgrading to 6.20 is STUPID and DANGEROUS. Don't risk your console's life for a permanent patch.

Hi.
I have just tried to downgrade to 6.35 and it tells me I have a newer version and it won't do it... I have no idea what to do. That if if I try to go to 6.35. If i try to 6.20 it tells me the file is corrupted.
In the attachement you can find a printscreen taken with Pspident of the CFW.

Please help?

Ah, it is a 09g PSP 3000. One of the "doomed" ones.

Try to downgrade to firmware 6.39, since 6.39 is supported by the PSP 3000 09g.
