How 2 upgrade

It depends what firmware you are trying to upgrade to. If you want to install custom firmware on your PSP, check this YouTube channel:
If you want to install official firmware, you can find a list of downloads here:
When you select the firmware you want to install, download it. You will get a .zip file with a file inside called EBOOT.PBP. Follow these steps to update:
1.) Connect your PSP to your PC. 2.) Open the PSP folder and then the GAME folder. 3.) Right click INSIDE the GAME folder, and click New Folder 4.) Name the new folder UPDATE 5.) Place the EBOOT.PBP file you downloaded into the UPDATE folder. 6.) Disconnect your PSP from your computer, and select the MEMORY STICK ICON in the GAME section. 7.) Find the PSP Update Version.. and run it, complete the on screen steps to install the new firmware.

Why I can't upgrade my psp1000 3.71 to 6.20?

The 3.71 firmware is a 3rd party custom firmware. 6.2 on the other hand is Sony's official firmware. Essentially it's like running Apple but wanting to upgrade to Windows 7, since you're running a different firmware, you won't be able to upgrade to the official 6.20.

I upgrade my psp in version 5.01, now i cant play my games

HELLO! There's no need to downgrade ur PSP. If u have upgraded ur PSP from the official site and a official firmware has been installed on to ur PSP, it won't execute games(ISO,CSO) from ur memory stick. It will only run games from the UMD. If u want to run ur games from a memory stick u have to install a CUSTOM FIRMWARE. Try these guys have many softwares on their site. Dont worry its not that hard to put a Custom firmware onto ur PSP.

XiaoFeiChong's Custom Firmware 5.02

If you want to upgrade, you must downgrade first. Any custom firmware upgrade cannot take place unless your PSP is firmware 1.5 or lower.

Chances are that you have a different firmware. If you want to get a custom firmware and downgrade, it is a very complex process that I do NOT recommend if you do not know what you are doing. It is very easy to ruin your PSP during the process. If you are still interested, research "Pandora's Battery" and other downgraders. It is a very long process too long to be explained here, and there are many guides online.

If you miraculously have a PSP that is firmware 1.5, I recommend getting firmware 5.00 m33-4 instead, as it is much more stable. Don't attempt anything unless you understand the consequences of possibly ruining your PSP.

Sorry if I scared you...

yeah, if your PSP is not Modded and it is running on official firmware of SONY, then you should prolly have it modded or have it made into custom firmware...If you don't know how to check the what firmware version your PSP is running...then here is how:
open your PSP, then on the XMB, got SYSTEM SETTINGS then to SYSTEM information. on the top it says SYSTEM SOFTWARE, then check if your firmware version has a m33 suffix...if it doesnt have an m33 at the end, then it is an OFFICIAL firmware so have it modded, my friend...
