Submitted by admin; August 25, 2011


Downgrade your PSP from firmware 6.31, 6.35, 6.38, 6.39 or 6.60 to any desired [official] firmware ... as long as your desired firmware is greater than or equal to the factory installed firmware (OFW) when you purchased your PSP.

This is a port of Davee's 6.31/6.35 downgrader, released by some1. Click here for more info.

v4.1 Changes
  • Added Source Code

  • Fixed 6.60 problem that didn't allow to downgrade to anything greater than 6.20, thanks to Davee

  • Special Sauce added by Proxima
v3.5 Changes
  • If the 6.20 updater MD5 check fails, it will check if the update file is 6.35, allowing non 07g/09g to downgrade to 6.35

  • removed a few debug printf's
v3.1 Changes

It work like a charm friends trust me I just read and follow the "readme.txt" (from your PC) and the on screen instruction (given in) after launching chronoswitch downgrader and after restoring you will get blue screen don't be scared of it (because: it just asking to restore setting) search for language you are able to read then it will resart and you are downgraded to 6.20. It work like it is told. Earlier I was on official version 6.60 and now i m on official firmware 6.20, it also downgrade from 6.35 to 6.20 I have tested even that, i have psp 3001 3g model. Please read and follow the step.

download official firmware you like  from here http://code.google.com/p/procfw/wiki/Installation and then extract it to PSP/GAME subfolder put it in folder named "UPDATE" (your update file loaction will look something like ms0:/PSP/GAME/UPDATE/) and extract the downloaded downgrader at the root of your memory stick (ms0:/)
