How to: PSP upgrade to 3.02 OE-B custom firmware

[Oz2]

First of all to be able to flash your PSP with Dark Alex's new custom firmware you need one of the following:

- a PSP with firmware 1.5
- a PSP with Dark Alex's custom firmware 2.71 SE
if you have none of these read no further and use our guide to downgrade your PSP to 1.50


Key Features of the 3.02 OE-B firmware:

- Play Playsation (PSX) Games on your PSP!
- Play ISOs straight from your memorystick, no need for Devhook nor any other software
- includes 3.02 kernel as well as 1.50 kernel which means Homebrew for both firmware versions is supported
- Recovery Menu for easy fallback to 1.50 as well as a lot of tweaking possiblities



How to flash your PSP to 3.02 OE-B:

First of all let's gather evrything you need for this

- Dark Alex's firmware upgrade 3.02 OE-A
- Dark Alex's firmware upgrade 3.02 OE-B
- Eboot of the original firmware version 1.50
- Eboot of the original firmware version 3.02

(these are the files i used and it worked just fine )


Now here is what you do:

- connect your PSP to your USB
- unpack the package with the files of Dark Alex's 3.02 OE-A firmware
- unpack both original update EBOOTs (1.50 and 3.02) and rename them like this:

• the 1.50 "EBOOT.PBP" -> "150.PBP"
• the 3.02 "EBOOT.PBP" -> "302.PBP"

- copy the folders "oeupmaker" and "oeupmaker%" to your GAME folder on your PSP.
(Note: if you are using a PSP with firmware 2.71 SE copy both folders to your GAME150 folder instead!)
- copy both files (150.PBP and 302.PBP) to the "oeupmaker" folder on your PSP.
- disconnect PSP from USB
- start OEUPMAKER ON your PSP from the Game Menu
(Note: this program does nothing to your flash, it only creates a DATA.DXAR file which is needed for the update and includes both firmware's kernels)

OEUPMAKER will run a test when it has finished creating the DATA.DXAR file. If the check is ok you are clear to proceed to the next step

- reconnect your PSP to the USB
- copy the "302oeflasher" and "302oeflasher%" folders to your GAME folder on your PSP.
(Note: again, if you use a 2.71 SE firmware PSP copy those to your GAME150 folder)
- move the DATA.DXAR file from the "OEUPMAKER" folder on the PSP to the "302OEFLASHER" folder on your PSP.
- disconnect PSP from USB
- launch 302OEFLASHER from your game menu
(this will launch the flash-update!!! note that this procedure could brick your PSP!!! we don't take responsibility for any problems that could occur during this procedure. Proceed on your own risk!)
- wait for the upgrade to finish. it will tell you to reboot your PSP manually. reboot manually now

Your PSP should now have firmware version 3.02 OE-A

Now, we wanted to flash to 3.02 OE-B didn't we?

Here is what you you do:

- unzip the 3.02 OE-B archive
- create a "GAME150" folder in the "PSP" folder on your PSP. (not needed for those of you who had 2.71 SE)
- copy the "OEB_UPDATE" folder from the archive to your GAME150 folder
- disconnect your PSP from USB
- launch OEB-UPDATE from your Game Menu
(this update will only take seconds and will reboot your PSP automatically)

Done! You should now have a PSP with Firmware 3.02 OE-B.

Thanks for the guide Oz. I've still got my PSP installed with 2.71 and the Epsilon BIOS, but am going to be upgrading soon to this custom firmware so I can play PSX games and newer PSP games that require newer firmare versions.

It is a bit annoying that this firmware is now available as it can do the same as a UP chipped PSP, but without needing the modchip or hardware modding.

I may wait for the 3.03 version to be released before I upgrade though as it has some new additional features over the current OE-B release.

I think 3.03 is already released.

Changes from 3.02 OE-B to 3.03 OE-A:

* Change from firmware 3.02 to 3.03
* Added support for compression in psx isos (look at popstation documentation for more details).
* Added support for decrypted document.dat (psx games manual) (look at docmaker documentation for more details).
* Fixed a bug regarding free region: a stupid bug caused it not to work at all. Now it should work, although it has not been tested due to lack of umd’s of different regions between the testers and me.
* Some generic bug fixes in the code.
* Re-added the sdk.
* Fixed some bugs that could cause the brick of korean/chinese/taiwan/singapure psp when restoring default settings. To prevent this, the region of those psp’s are faked to japanese when fake region is disabled. For same reason, korean region is removed from fake region.
* Added australia/new zeland and russia to the regions to be faked.

The installation is similar to 3.02 OE-A:

1. Copy oeupdatemaker and oeupdatemaker% to /PSP/GAME if you are in firmware 1.50, or to /PSP/GAME150 if you are in 2.71 SE or 3.02 OE.
2. Get the 1.50 and 3.03 sony updates, and put them in the oeupdatemaker folder with the names 150.PBP and 303.PBP.
3. Run oeupdatemaker. It will generate the dxar file DATA.DXAR, whhich has the following hashes:
MD5: 03186D46D2F1B0ACD923098BEBC87281
SHA1: 3C80833A970EEA16A94D74DAFF6220889A9CEE4A
4. Copy 303oeflasher and 303oeflasher% to /PSP/GAME if you are in 1.50, or to /PSP/GAME150 if you are in 2.71 SE or 3.02 OE.
5. Move the DATA.DXAR file to the 303oeflasher.
6. Run the program. When it finishes, it will ask you to reinit the psp. When you do that, you will be in 3.03 OE-A.

That's good if it has been released. On the PSP forums yesterday it wasn't out yet.

[Oz2]

Yes, it is out. I'm gonna test the upgrade for 3.03 OE-A next. All the newest files for PSP can be found on dl.qj.net

[Harrison]

Cool, thanks.

Let me know how the 3.03 OE-A upgrade goes. I take it you can upgrade from 3.02 to 3.03?
