HOWTO: Upgrade your PSP to Firmware 3.10 OE-A’

Caution! – This may brick your PSP if the steps are not followed properly! Please follow all of the instructions carefully, and if it doesn’t work and you brick your PSP, I didnt twist your arm, or hold a gun to your head, so don’t come crying to me.

3.10 OE-A and OE-A’ boasts an impressive list of feature updates including:

3.10 OE-A Changes

* Change from 3.03 firmware to 3.10.
* 4th level of brightness (aka battery eater) can now be selected also without ac adaptor.
* Changes in hen core:
– Static user elf’s can now be executed in the 3.10 kernel. (this includes snes user version between other programs)
– Tyranid’s patch (added in 3.03 OE-C) consequences was not explained very well in the changelog of 3.03 OE-C:
o For programmers: it allows kernel modules to have user imports, making kernel programming in 3.03/3.10 less strict.
o For users: plugins and applications that worked in 2.71 SE, but not in OE, *may* now work in 3.03OE-C and 3.10 OE-A.

Note 1: the installer will disable all plugins to avoid incompatibilities when booting. You can enable them again in the recovery menu.

Note 2: the plugin to load 3.02 pops won’t work anymore in 3.10 OE, due to some changes in pops modules structure (meaudio fused with popsman, idcanager/idmanager behaviour slightly changed). A new plugin for 3.10 could be written next week.

3.10 OE-A’ Changes:

* Corrected a bug that caused Metal Slug 6 (from Metal Slug Anthology), and other umd/iso games containing a static elf to show error 0×80020148.

To upgrade to firmware 3.10 OE-A’ you must first be running 3.10 OE-A, so we will start by upgrading to that firmware first.

Step 1. The first thing you will have to do is download all of the files needed for the upgrade.

310oe_a.rar
310_a2update.rar

Step 2. First you will need to upgrade to 3.10 OE-A before you can go to OE-A’. Uncompress the 310oe_a.rar and copy the contents to /PSP/GAME150 on your PSP using the USB file transfer mode. *NOTE* If you are upgrading from PSP 1.50 firmware just copy the directories to /PSP/GAME.

Once these directories are copied, go to the game menu and run the 3.10 OE-A Update Maker. This step will take a little bit, so be patient. Now would be a good time to make sure your PSP is plugged into the power and not running off battery mode. You will need to have your battery at, at least 75% for the upgrade to be a success.

Step 3. After the Update Maker is complete, initiate USB file transfer mode again and go into /PSP/GAME150/oeupdmaker and copy the data.dxar file to /PSP/GAME150/310oeflasher. Once this file is copied over, exit the USB file transfer mode, go back to the GAME menu, and run the 3.10 OE-A Firmware Install.

Once the installer loads up press the X button to continue with the upgrade. It will now verify the data.dxar file and proceed with the upgrade. Once the upgrade is complete you will then press X again which will turn off your PSP. Turn the PSP back on manually.

You are now running the 3.10 OE-A firmware.

Step 4. Now proceed with uncompressing 310_a2update.rar. Go back into USB file transfer mode and copy over the 310_a2update folder to your /PSP/GAME150 folder. Exit USB file transfer mode, go into the GAME menu and run the 3.10 OE-A’ Updater. This will quickly update your firmware and exit back to the XMB. You are now running the 3.10 OE-A’ firmware.

Step 5. To clear up space on your memory stick you can now go back on your PSP and delete all of the files we copied over.

Enjoy your updated firmware!
