Monday, May 23, 2011



Works on PSP 1000, 2000, 3000, 4000 (newer 3000) or PSPgo!

You can downgrade with this downgrader from Firmware 6.38 to Firmware 6.20. From Firmware 6.35 to Firmware 6.20. And from Firmware 6.31 to Firmware 6.20.

Supported models:
PSP1000 [01g], PSP2000 [02g], PSP3000 [03g / 04g], PSPGo[05g]

Unsupported models:
PSP 3000 = 07g / 09g, etc. Can not be used (with error display)

I tested it by myself on a PSPgo with Datecode 9C and Firmware 6.38 ;=).

For this, you will need:
- PSP 1000, 2000, 3000, 4000 (newer 3000) or PSPgo
- a supported PSP model
-6.38/6.35/6.31 -> 6.20 Downgrader By Davee, ported to 6.38 by some1
-Official PSP Firmware 6.20 for PSPgo or normal PSP

2.Ms0: (ef0 / PSP / GAME / copy the Downgrader to this folder.

    No offense meant to the uploader/author, but has this worked for anyone yet? Only got the one PSP and I am afraid to brick it...
