1. Download THIS and THIS

2. Extract the 3.03 Downgrading package with winrar.

3. Copy over the PSP folder into the root of your PSPs memory stick overwriting anything it asks you to overwrite. (Please note, backup anything you want before overwriting!)

4. Now, extract EBOOT_1.50 with winrar, and rename EBOOT.PBP to UPDATE.PBP

5. Copy UPDATE.PBP to ms:0\PSP\GAME\UPDATE, if you don't have an UPDATE folder in your GAME folder, create one.

6. Make sure you rename the file before you copy it to your memory stick. Do not overwrite EBOOT.PBP

7. Your UPDATE folder should now look something like this:

8. Once you've done that, launch your GTA LCS UMD from the PSP. It should proceed to load the save game.

9. Your PSP screen should turn black and the reset it self.

10. Ok, now check that HEN is running by going to system settings on your PSP and select "System Information". It should say "303 HEN"

11. If for some reason the PSP isn't saying "3.03 HEN", launch GTA again until it shows "3.03 HEN"

12. Now, plug in your PSP charger, and keep charging untill you have AT LEAST 75% battery charge. 100% is recommended, but 75% will do fine.

13. Now head over to the game menu on your PSP, click on the memory stick icon and then click on x.yz update icon.

14. At this stage, if you have a TA-082 motherboard the downgrader will patch the motherboard so you can carry on.

15. Agree to the terms and conditions by pressing R. Only do this if you want to proceed and downgrade.

16. The downgrader should start. DO NOT UNPLUG THE PSP CHARGER, TAKE OUT THE PSP BATTERY, TURN OFF THE PSP OR TAKE OUT THE MEMORY CARD!

17. Once done, the PSP will ask you to press X. This will reboot the PSP.

18. The PSP may show a warning that the settings are corrupt, press X and go to GAME on the PSP. Run the PSP Network Config Backup application.

Done? Congratulations! You should have a 1.5 PSP! Head over to the "System Settings" and double check you have a 1.5 PSP!
