Installing Pro CFW on your PSP1000 is simple, free, and is not much risky than installing a Firmware update on your device.
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.
In this page I’m describing the easiest possible way for you to install the most reliable Custom Firmware on your PSP: Pro CFW.
As a PSP 1000 owner, you can practically install everything you want on your device, and use other techniques such as the Pandora Battery to install a Custom Firmware.
There’s basically 3 easy steps (you were expecting more?
Sorry to disappoint): Skip this step if you already have Firmware 6.60 installed on your PSP.* Installs the Noobz Pandora 1.50 Downgrader to your PSP. Installing a Custom Firmware on your PSP 1000 has never been so easy.This is done by running the tool 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.However, every time you reboot your console, you will have to reactivate Pro CFW, which is done by running the Fast Recovery tool from your PSP’s Game menu, and takes literally 5 seconds.
