I have just recently bought a PSP 3.03. How do I upgrade this psp to a 3.90 m33 or another more advanced firmware. Is there an auto installer for the psp, or do I have to downgrade and then do other stuff?
Thanks.

Requirements
In order to downgrade a 3.03 PSP you will need the following:
Original GTA LCS (any region), which should have the 2.00 update on the disc.
3.03 Downgrader (this package)
1.50 Update
3.03 Update if you are on firmware 2.81 to 3.02
Instructions
Here are the steps to downgrade any 3.03 PSP to 1.50:
Download 3.03 update
Unzip and place the file in :/PSP/GAME/UPDATE
On the PSP, run the 3.03 update from the memory stick under the Game menu.
Delete :/PSP/GAME/UPDATE
Copy the contents of the folder MS_ROOT from the 3.03 downgrader ZIP to the memory stick
Unzip the 1.50 update to a temporary folder. Rename the EBOOT.PBP to UPDATE.PBP and copy it to :/PSP/GAME/UPDATE/ . DO NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP!
Load GTA LCS
It should get to loading savegame, then the screen will clear to black and fill with a light blue colour, then the PSP will reset itself (if this does not happen see section below)
Check that HEN is running by going to system settings, then to "System Information" and it should show up as system version 303 HEN
If it is showing up as HEN then go to the memory stick and run the x.yz update
If you have an unpatched TA-082 or higher motherboard, you will be prompted to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it.
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).
Once you have agreed to start the downgrade do not unplug the PSP, or try and restart it
Once finished the PSP will ask you to press X, and reset itself
If it comes up saying that the settings are corrupt, press x to continue, this will mean you will need to re-enter the settings for network connections into your PSP,
Load the included NetConfigBackup application in your PSP, and select to restore, this will take the backup that was done of the network config that was done automatically during the downgrade.
All done now :-) Hopefully you now have a 1.50 PSP. Enjoy it responsibly.
Troubleshooting
Ensure that you have the original GTA LCS, it should have a 2.00 update on the UMD, if it does not then it is a later version and can not be used to downgrade.
If GTA does not load 3.03 HEN and it loads up a save game, try making a backup copy of all of the directories in :/PSP/SAVEDATA/ before deleting them. Then try copying the contents of the 303 HEN zip to there.
If when trying to restore the network config using netconf backup you find that it gives you an error on the downgraded 1.50 PSP, try adding a temporary network config, then deleting it and run the netconf backup again.
