PSP CFW -> Upgrade Path?

[CrimsonWesker]

Hey all.

So I've got a PSP (Fat) which is currently (succesfully) running CFW 3.71 M33.

Can anyone recommend me how to upgrade to the latest CFW?
For example, can I upgrade directly to the latest version or do I need to update to other types first?

Thanks guys.

Hi. Since you're already on 3.71 M33, you can upgrade directly to the latest M33 firmware without any problems. Lucky. That would be 3.90 M33-2. You can download it here. Putting it on your PSP is incredibly simple -- all the details can be found in the readme file that comes with the download. But even so... here they are:

- Copy the UPDATE folder into /PSP/GAME/
- Get the 3.90 Sony update from somewhere, and put it in same folder, with name "390.PBP".
- Run it, the update will be done by Sony updater. At the end when you are asked to reboot the
PSP pressing X or O, do it.

The 3.90 Sony update can be downloaded here. Have fun
