Just a quick tutorial on downgrading the PSP Go. This works on 6.60, 6.39, 6.38, and 6.35 to drop the firmware lower. Do not attempt this on the PSP Slim or Phat, as these downloads will not work. If you need help downgrading a Phat or Slim, check my channel, there are plenty of videos there for your use :)

**IMPORTANT NOTE**
If you encounter an error that says "There is no need to update, a later version of the system software is already installed."

Open the Archive you downloaded, connect your PSP to your computer. Open the PSP folder on your PSP, and then the GAME folder. Delete the folder inside of GAME called "6.xx Downgrader v4" and then go back to the root of your memory stick (or disconnect your PSP, and connect it again). Next, drag the PSP folder onto your memory stick's root (do not drop it into ANY folders, just drop it into X:\ where X is the letter of your PSP). That is an updated version of the Downgrader, and should work PERFECTLY. Thanks to AvgMaplerZz for pointing this out to me. Much props :)
