There have been several iterations of the PSP hardware over the years, and there are some differences in what kind of CFW you can get running on each.
Regardless of which hardware revision you have, go ahead and copy the PROUPDATE into the PSPGAME directory on your memory card.
You’ll now see a Pro Update application in your PSP, run it and allow it to complete the installation.

If you have a new memory card, please format it first by putting it into your PSP, then choose Format Memory Card from the System Settings menu.
