    Can I go directly from 3.71 M33 to 5.0 M33-3?

    Or is there a specific method of doing such?

    Try using the network update on your psp.
    It will tell you what its going to update to.

    Cheers

    Just download the newest firmware from Dark_AleX's site.

    Read the instructions in the readme.

    Don't network update unless you have 3.71 M33-3.

    Install 3.71 M33-3 first. Then I'd recommend just downloading 5.00M33 then installing it from memory card rather than network update.

    Thanks! That worked like a charm.

    However, I have a problem now. My two psp backups that worked under 3.71 M33 no longer work under 5.00 M33-3. They don't even display icons for the games in the game menu.

    Is there something I have to do to bring back support for .iso game backups whilst using 5.00 M33-3?

    Try to fresh format your memory stick everytime you update to a new firmware.

    Also try to enter recovery menu to switch your UMD drive between M33 Drive and Sony Drive. The backup might work in one of those.

    Hey thanks!

    I did both of what you suggested, and it works again.

    Cheers.
