Download PSP Firmware 5.50
Open the PSP folder in the zip and copy the PSP folder inside it to your memory stick. It's listed as "PSP Update ver 5.50" under Game > Memory Stick. Run it on the charger, not the battery alone.
Running M33 or another custom firmware? This puts your PSP back on Sony's stock firmware, and it only goes one way, so leave it alone unless a game insists on it.
Newer version: PSP Official Firmware 6.10
