Hi! A friend gave me his old original fat & heavy style PSP. It has 3.40OE firmware.
I need to update it to the latest official (or unofficial if I have to) firmware so I can play more recent games. I really don't care about homebrew/custom stuff at all. I just plan to play off the shelf PSP games (I prefer to play the classics on my laptop with Saturn controller ;)).
My friend said something about possibly not being able to install the official firmware? He doesn't remember the details but something about changing the "keys" when it was hacked. I don't really understand any of this, to be honest.
Basically I want to know if/how I can change from 3.40OE to the offficial firmware.
