PSP 2.81,3.00,3.01,3.02 and 3.03 Downgrader (TA-082 Support)

Post by TOP_DVD »

Hope this comes in handy all you need to run buckup psp games on PSP 2.81,3.00,3.01,3.02 and 3.03 :wink:

This downgrader is for v3.03 firmware only. But if you have v2.81 - v3.02, no problem - you can just upgrade to v3.03 to use the downgrader.

You need a copy of the unpatched GTA:Liberty City Stories UMD. No ISOs, no patched UMDs, not Vice City Stories. See Here for some info on how to check if your version is patched. The most reliable way : the unpatched disks have the v2.0 firmware update on them.
It's safe to downgrade any PSP regardless of the region.
The downgrader will work on all current PSP Motherboards (TA-079 - TA-086). Patching of TA-082+ is automatic in the downgrader.

• You downgrade at your own risk. There is always a chance of bricking, although fanjita says he did everything he can think of to make this process safe.
• Warning: After downgrading from 3.03 to 1.5, there are some remnants of 3.03 left in flash. If you later try to re-upgrade to 3.03 and repeat the downgrade, things will break. At some later point, Fanjita will work on a cleaner downgrader, that will remove these extra files. Until then, enjoy! (Don't worry, upgrading to 3.03+ OE firmwares still works fine).

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.

- If you have a 2.81,3.00,3.01 or 3.02 update to 3.03 and then use this downgrader.
update can be found in the folder "3.03update"

update to 3.03

Double click 303_update.exe, choose your psp drive,
then extract and everything's installed.
Run from game menu and follow onscreen instructions.

Plug Ac Adaptor plugged in.
Have battery more than 75% full.
Backup MemoryStick and then format it.

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

1 - Double click 3.03_downgrader.exe and extract the contents to memorystick, overwrite if asked.

2 - Load up GTA LCS

3 - 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)

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

5 - If it is showing up as HEN then go to the GAME menu then Memory Stick and
run the PSPtm Update x.yz update

6 - 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.

7 - 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).

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

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

10 - If it comes up saying that the settings are corrupt, press x or o
to continue.

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

Hint: If you psp has a blank screen after it resets, press the screen brightness
button a few times and it should sort it out.

After downgrading you can format MemoryStick again.

What to Do After You Downgrade?

After you downgrade, i guess you want to play all your favourite homebrew, emulator's, media players, organizer's,
ISO loader's, etc.

Do not upgrade back to 3.03 or you will brick your psp, but you CAN upgrade to 3.40oe.

Well on 1.5 you can load all the homebrew you want and emulate 3.03 with Booster's "Devhook" to play all the latest psp
games out for your psp. But I and the majority of the pspscene now use Dark_Alex's "Open Edition Firmware". The latest is version 3.40oe-A.
