Developer's note:

This a very simple app, just put the official 6.20 updater in (ms0/ef0 accordingly)PSP/GAME/UPDATE, and run the downgrader, this will reboot into the 6.20 "update", and allow you to downgrader to 6.20. Has been tested on 1k, 2k, 3k, and Go (added support for 07g/09g).

I will be releasing the source on May 29th.

Instructions:

If you have anything lower than an 07g place the 6.20 update in PSP/GAME/UPDATE.
If you have an 07g or an 09g, place the 6.35 update in PSP/GAME/UPDATE.

Important note: You run the application at your OWN risk. I am not held accountable if you (No Language Please) up your PSP.
Another important note: After you downgrade to 6.20, you will get a BSOD (saying that your system information is corrupted), this is OK, just click circle to reset your system information and you will be back to normal.

Final important note: It does indeed still support 6.35/6.31

This app is also the devs entry for the ongoing PSP Genesis Competition 2011.


Update: some1 has released an updated version of his 6.38 Downgrader to be compatible with 07g & 09g PSP models. The download link has been updated below.

Update #2: some1 has released yet another update to his Downgrader making it compatible with the just released firmware 6.39. Download links below have been updated.
