Hello, I recently got a PS3 and found out that you can transfer downloaded psone classics to your psp. I haven't touched my psp in years and a friend of mine had put homebrew on it for me years ago. I really would just rather update my psp to the legit latest update that sony has out because I dont use any of the homebrew i have on my psp. Plus i want to play some newer psp games. I try to update the system through the network update feature, it downloads fine but when i try to install the update nothing happens. It starts up as if i had just put in a game with the white screen and psp logo, but then after a few seconds of the screen being black it just goes back to the home menu as if nothing happened. If someone could help me out with a process on updating my psp's firmware and reverting it back to normal it would greatly be appreciated.
