Make sure not to overwrite PSP/GAME/UPDATE/EBOOT.PBP
4. Load GTA LCS
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 Game menu 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).

10. Once finished the PSP will ask you to press X, after pressing it will reset it self. (If it don't reset press O instead)
11. If a blue screen (BSOD) comes up saying that the settings are corrupt press X or O to continue.
12. Enjoy the new 1.5 PSP
