How do you unlock a PSP?

To unlock a PSP (PlayStation Portable), you typically need to install custom firmware (CFW) that allows access to additional features and homebrew applications. This process often involves downloading the appropriate CFW files, connecting your PSP to a computer, and transferring the files to the device. Be aware that unlocking your PSP can void warranties and carries risks, including the potential to brick the device if done incorrectly. Always follow detailed guides and ensure you understand the process before proceeding.
