Fanjita may have told you guys what to do with a non-homebrew capable PSP, but now it appears that everyone can get in on the homebrew fun! The "goofy exploit" which exists in firmwares 2.00 to 3.03 was found on Friday, January 25, 2007, a date which you'd think might go down in the PSP homebrew history. But it probably won't because despite their seven-day ETA, the Noobz team has once again fortified its position at the top of the homebrew coding ladder with a 3.03 downgrader - just three days after the exploit was found!

1. Update to firmware 3.03. If already have this firmware then proceed to step 2.

2. Open the 3.03 downgrade file and copy the contents of the folder MS_ROOT to the root of your memory stick.

3. Open the 1.5 update and rename the EBOOT.PBP to UPDATE.PBP then copy it to /PSP/GAME/UPDATE/
Make sure not to overwrite PSP/GAME/UPDATE/EBOOT.PBP

4. Load Grand Theft Auto: Liberty City Stories (unpatched)

5. It should get to loading save game, clear the screen, the screen should fill with a light blue color and then reset the PSP
(If this does not happen see below)

6. Check that HEN is running by going to system settings then System Information and it should show up as system version 303 HEN

7. If it is showing up as 3.03 HEN then go to the memory stick and run the x.yz update

8. Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing
If you no longer want to continue press the Right Shoulder Button (R-TRIGGER).

9. Once you have agreed to start the downgrade do not unplug the PSP

10. Once finished the PSP will ask you to press X, after pressing it will reset it self.

11. If it comes up saying that the settings are corrupt press X to continue.

12. Enjoy your new shiny 1.5 PSP.
