Assuming you extracted the files correctly, you will see a few new applications in your PSP’s Game menu. The one you will want to run in order to install Pro CFW is “Pro Update”. Just run it.

That’s it. You can erase the “ProUpdate” folder from your PSP, but keep the “FastRecovery” one.

That’s it, I said 3 steps ? Welcome to the world of Custom Firmwares. There’s no additional step required to install the Pro CFW. However, every time you reboot your console, you will have to reactivate ProCFW, which is done by running the Fast Recovery tool from your PSP’s Game menu, and takes literally 5 seconds.

In this section you will find additional tricks/steps if you want to improve or customize your experience with a Custom Firmware on your PSP 1000

Some people think that it is a burden to reactivate the CFW every time they reboot their console. It is important to note that this is needed only if you reboot the console, not if you put it into sleep mode. Most people use the sleep mode 90% of the time without ever realizing it. Trust me, I’ve used several PSPs for years now, running the Fast Recovery tool is not a problem in your daily usage. That being said, since you’re running on a PSP 1000, you have a possibility to install the CFW permanently. This is done by running the tool CIPL FLasher from the Pro CFW (included in the archive). I won’t dig into the details for that (just run the tool will do the trick), just know that I personally think this is a feature you won’t need (and there is an additional risk of bricking your PSP) unless you use your PSP for dev purposes.
