How to Downgrade a PSP

How to Downgrade a PSP

Now that you have all the files and instructions necessary to downgrade your PSP, here are the instructions on how to proceed:

1. You need to disable any anti-virus programs, or any security application in your PC before you proceed with downgrading
2. Follow carefully the instructions in copying the files for downgrade in the ROOT and PHOTO directory of your PSP. (note that the instruction are included in the files that you downloaded)
3. Plug in the AC Adaptor and connect it with your PSP
4. Scroll over to the "Photos" menu, press X, and scroll down.
5. If the console of your PSP hits a blank screen with letters and numbers on it, or freeze, restart your PSP. If it happens again, try doing a hard reset the holding up the power switch until the unit turns off.
6. When the PSP boots up, scroll over to your memory stick under "Game" and run the 1.5 US update which you copied earlier. The update will load but will inadvertently fail at 99%. Never fear since this is supposed to happen.
7. Restart the PSP when it does until the screen turns blue. Press O, and you are done!

If you see a 1.50 firmware logo after your PSP reboots, then you have successfully downgraded your PSP, and access its amazing features.
