Set up Workstation
Like many tasks, the hardest part of changing your PSP's faceplate is getting the original faceplate off. Make sure you have a suitable work space (a flat kitchen table is fine) and you have your small screwdriver ( a mini-Phillips works best) and lint-free cloth close at hand. It also helps to have a small tray to store the screws and buttons that you will need to remove during the process.
Remove Original Faceplate
Once your work station is all set up, take your cloth and remove all the dust from the faceplate and the buttons. This is very important, as any dust that gets inside the PSP can severely hamper performance. Once the dust is removed, put the PSP face down on the table and locate two screws from the back of the PSP. Remove these screws to reveal two hidden screws along with the warranty sticker. Remove these screws (and yes, this does void your warranty) and then flip the PSP back over. The analog nub on the front of the PSP should be loose to the touch. Gently pry the analog nub up at a 45 degree angle and then gently unscrew the two screws holding the rest of the analog unit in place. The current PSP face will now be completely unattached. Lift it up, and set the faceplate, as well as the PSP aside
Assemble and Attach New Faceplate
Assemble your new faceplate by taking the analog unit that you just removed and screwing it back into place. Go back to your PSP and pull the face buttons and bottom buttons off the face of the console (they should be lose enough to do this) and then push them into the holes in the new PSP faceplate. Once the buttons and analog unit are attached to the faceplate, it is time to attach the faceplate itself to the PSP. Carefully put the new faceplate over your bare PSP console and then secure it by flipping it over and putting the two screws under the battery cover back in place. Then replace all the external screws you removed previously to secure your new faceplate completely.
