    Here are the steps to downgrade any 3.03 PSP to 1.50:

    1 - If you have a 3.03 PSP skip to step 6

    3 - Unzip PSP_303_UPDATE the file in :/PSP/GAME/UPDATE

    4 - On the PSP, run the 3.03 update from the memory stick under the Game menu.

    5 - Delete :/PSP/GAME/UPDATE

    6 - Copy the contents of the folder MS_ROOT from the 3.03dg ZIP to
    the memory stick

    7 - 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

    8 - Load GTA LCS

    9 - 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)

    10 - Check that HEN is running by going to system settings, then to
    "System Information" and it should show up as system version
    303 HEN

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

    12 - 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.

    13 - 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).

    14 - Once you have agreed to start the downgrade do not unplug the
    PSP, or try and restart it

    15 - Once finished the PSP will ask you to press X, and reset itself

    16 - 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, otherwise go to
    step 18

    17 - 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.

    18 - All done now :-) Hopefully you now have a 1.50 PSP. Enjoy it responsibly.

    - 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
