We came a long way from downgraders, different Exploits and the discovery of the Pandora Battery. If your PSP is 9g, you can only install the Custom Firmwares temporarily. If your g is something else than 9, you can downgrade and install the 6.20 PRO permanently. If you have a PSP 3000 and installed your PRO, always look into the System Information and notice what g you have.

These PSP's can't be downgraded to 6.20 (DON'T TRY IT, YOU WILL RECEIVE A BRICK) and you can't install the 6.20 PRO permanently to the PSP. They have the modelnumber 9g and new drivers. Newer PSP 3000 models come with Firmware 6.35.

On this PSP's, you can only install the 6.20 PRO temporarily or the 6.35 PRO 9g is limited to PSP 3000, so if you have a PSP 1000, 2000 or Go, you don't need to worry about it. Some new models of the PSP 3000 (9g) doesn't allow you to install it permanently. The 6.20 PRO can't be installed permanently on every PSP. The compatibility should be nearly or exactly the same for backups, homebrew and plugins. If a permanent patch for 6.35 get's released, I will update this thread to reflect the new changes. A permanent patch for it would require a lot of work. This is due to the new checks that were build in the 6.35. The 6.35 PRO and 6.39 PRO can only be installed temporarily and will be erased as soon as you turn off your PSP. That means, if you turn off the PSP, that it is still installed. The main difference between those two is, that the 6.20 PRO can be installed permanently. This tutorial was created by me, but every program in this thread was created by others.ĭifferences between 6.20 PRO, 6.35 PRO and 6.39 PRO: I AM NOT RESPONSIBLE IF YOU BRICK YOUR PSP. I also added the downgrading option for the people who want to have the permanent 6.20. A Custom Firmware for Firmware 6.20, one for Firmware 6.35 and one for Firmware 6.39.
