( 
)Firmware, what you should know, and need to know.
For starters, Firmware is what you could call the PSP's OS. The firmware contains such things as the MP3 Player, the Photo Viewer, and other features found on your PSP. The PSP's Firmware is stored on what's called a "Flash Disk."
Now, when Sony finds bugs, or flaws in the OS, they release new updates and upgrades to the firmware. There are currently three different firmware versions. Version 1.0, Version 1.50, Version 1.51 and Version 3.10
What do the different Firmware Versions mean?
A lot. At this time, only PSP's with Version 1.0 and 1.50 Firmware can run what's called "Unsigned Code." What does this mean? It means that Version 1.0 and 1.50 PSP's can run all the Home-made applications and games you can find here on the site!
Here's an example of the encryption: When you boot up a application with version 1.0 or 1.50 using KXploit , the PSP says: "Oki doki." But when you boot up an application with ether version 2.0, or 3.03, the PSP says "Oki doki...you want me to run this? What's the secret password?" If the program doesn't give the PSP the password, then the PSP wont even fully start the program, and it'll boot you right back to the home-menu.
Why doesn't someone just crack the password? Because it's in 128 bit (maybe more? Not sure on this) RSA Encryption. What's this mean? It means it's a royal pain in the butt to get the password.
So how do I know which Firmware I have?
Just goto the PSP's main menu, then goto the following menu's: ~Settings ~System Settings ~System Information
Then you should see where it says: System Software Version 1.xx (The xx will change, depending on what version you have, of course)
WHA?! I can't run anything! I have Version 1.51 or higher!
That's right! Trust me, you're stuck on the same boat as a LOT of people. But that doesn't mean you have to give up hope! People across the entire GLOBE are working towards getting home-made applications to run on Version 1.51 or higher. ^^ So just stick in there. The PSP hacking and modifying genre is still in it's infancy.
So why not just do a roll-back on the Firmware?
You can now with GTA downgrader.
You don't have a unpatched GTA. BUY ONE FROM ME. Take care.
