6.35/6.31 -> 6.20 Downgrader by Davee

I know, I’m 24hrs late on this one… real life does that to people.

As he announced a while ago, Davee release a downgrader for people who are on OFW 6.35/6.31 and want to go back to 6.20. You already know it works, but I tested it for you on my psp3000 (Davee, I actually trust you so much that I didn’t even try on my phat before that :) )

As you probably already know, we’re currently in a weird situation on the PSP scene, where two systems exist for Homebrew fans. One called TN Hen for 6.20 users, the other one is Hen Pro for 6.31/6.35 users.

Both these Hens (Homebrew Enabler) have pros and cons, support different plugins, have different homebrew compatibility. Let’s be honest, I was expecting one to take over the other, but that never really happened.

So, as a user, you are given a choice between 6.20 and 6.35. Of course, once on 6.35, you can’t go back, so if you don’t like this firmware, you’re kind of screwed…well that was true until this release. Now Davee gives you the possibility to test both 6.20 and 6.35, then choose which one you like…and change again as much as you want if you have lots of free time on your hands.


  1. Download here (or mirror here)
  2. Copy the “PSP/Game/downgrader” folder in the PSP/Game/downgrader folder of your memory stick.
  3. download the 6.20 Firmware update here
  4. Put the 6.20 firmware update in  PSP/GAME/UPDATE/EBOOT.PBP
  5. Run the “downgrader” from your PSP, and follow the instructions (wich consists in pressing “X” when asked to).

This is a nice utility (and impressive too, considering that Sony blocked the “usual” ways of downgrading in recent firmwares).

Davee’s Downgrader uses works from other devs in the scene, and the Readme gives thanks to bbtgp, coyotebean,  kgsws, Silverspring, and Bubbletune.

The package includes full sources (and a README if the instructions above are not enough), what more do you want? :)

downgrading is a risky procedure, and if you mess up you can end up with a bricked PSP. This downgrader has been confirmed by enough people to work, but don’t downgrade unless you really need to!

    Dont do like this > PSP/GAME/UPDATE/PSP_620_FW_UPDATE > this will corrupt and wrong.

    Please do like this > PSP/GAME/UPDATE > Work Fine.

    That UPDATE is PSP_620_FW_UPDATE ( Just Rename it to UPDATE) or PSP_620_FW_UPDATE( Rename this file to UPDATE).

    I didnt understand what the crap was meant by “Copy the “PSP/Game/downgrader” folder in the PSP/Game/downgrader folder of your memory stick.” Was i supposed to just stick that PSP folder in the ORIGINAL PSP folder itself? or was something else meant by that -.-
