Image unavailable (removed by its host) Image unavailable (removed by its host) Downgrading the PSP from firmware 6.35 to 6.20 To downgrade your PSP from firmware 6.31 or 6.35 to firmware 6.20, we're going to use the downgrader by Davee. Warning, PSP 8G and 9G models cannot downgrade below 6.30, so move along. Like any software that touches the PSP's flash 0, there are risks of bricking.
Tgames and the developers of the programs cannot be held responsible in case of a brick (any installation or update must be done with a full battery and plugged into mains power, don't turn off the PSP during installation, etc...)
If you don't know whether your PSP is downgradable, you can identify your PSP with psp ident, that's done here. So we're going to download the downgrader. Version psp go

Extract the archive to the root of your memory stick, once you're ready go to the gameicon, scroll down to memory stick, press X . Go to 6.35 downgrader like in the picture! Image unavailable (removed by its host) Now press X! Another screen appears, offering you to press X to start the downgrade or R to quit. Image unavailable (removed by its host) If you're ready press X. The downgrader will check the integrity of the files and start the downgrade. After a few seconds the PSP turns back on and offers you the update to 6.20, follow the on-screen instructions and start the update. The installation finishes, the PSP restarts and shows you a beautiful blue screen, press O, the PSP restarts. (If an error appears at the end of the update, don't worry, at around 90% the update is already in place, you just need to restart the PSP) Image unavailable (removed by its host) The PSP will ask you to reconfigure it (date, time, network, etc...) All you have left to do is go into system info to check that you're indeed on 6.20.
