The guide is as below starting from the very beginning - you can skip ahead if you already have a formatted memory card installed.1. If it needs to be formatted, the system will notify you; follow the on screen prompts to complete the formatting process. Connect the PSP to your PC or Apple using the USB cable.
Allow the computer to recognise the memory stick.3.
You can update the system software for the PSP™ system using any of the methods listed below.
Download the update data directly to the system from the Internet.
Step 3: Before you copy the file to the Memory Stick Duo, you first need to create a few folders.
On the stick, create a folder called PSP, then create a folder inside that called GAME, and finally create a folder inside GAME called UPDATE.
I always have and always will believe that it’s worth installing an upgrade to firmware for any device, whether it be a computer, wireless router, or game console.
In this article I am going to walk you through the steps required to upgrade the firmware on a PSP device.
Fortunately, updating your PSP's firmware is not difficult, though it can be a little confusing at first.
I recently bought a Sony PSP and after downloading some games to it from my PS3 I got a message along the lines of "This software requires update version...whatever" So I googled "update PSP" and got the official UK Playstation website and downloaded the file called EBOOT.
PBP the Sony website said "copy it to your memory card to perform an update". Problem is Sony don't tell you that you have to copy it to a specific location!!
PBP in the folder PSP/GAME/UPDATE - it is important the the folder names are ALL CAPITAL LETTERS.
Then, with your PSP charged (and preferably still plugged in to avoid battery glitches), go to the games section, select Memory Stick and then select your update.
