303 HEN Noobz Downgrader Guide
------------------------------
Here is a guide for downgrading any current PSP hardware version
(TA-079 - TA-086) from firmware 2.81-3.03 to 1.50.
IMPORTANT:
The Noobz team is strongly against piracy, and we're not just
saying that to cover our butts. When you pirate games, you're
removing the incentive for game and console makers to continue
making fun things for us to play with. We are releasing this
downgrader because we believe that using your PSP to its full
potential and being able to customize it and run homebrew code
is a fair use right that should be available to everyone.
Please purchase games that you intend to play. 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.
************************************************** ****************
* WARNING, ANY DOWNGRADER HAS A CHANCE OF BRICKING A PSP. WHEN A *
* PSP IS BRICKED YOU WILL NOT BE ABLE TO USE IT ANYMORE. WE HAVE *
* DONE A LOT TO TRY AND MINIMISE THE RISK, BUT THERE IS ALWAYS *
* SOME LEVEL OF RISK WHICH YOU MUST ACCEPT IF YOU WANT TO *
* DOWNGRADE *

Instructions
------------
Here are the steps to downgrade any 3.03 PSP to 1.50:
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 3.03 downgrader 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
OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP!
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
18 - 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.
