OE Custom Firmware Install Guide

This is a guide for installing every OE firmware. Yeah, I know, this seems pointless and outdated, but it can be an available resource for those still on firmware 1.50 or on an older OE firmware.

Your computer might not recognize RAR files, get WinRAR if needed.

------------------------------------------------------------------------------------------------

Requirements:

-A PSP-1000 model running firmware 1.50 or a custom firmware with the 1.50 kernel.

------------------------------------------------------------------------------------------------

Warning:

Do NOT attempt to run on a PSP Slim (that's running TimeMachine firmware 150_340) or you will brick! If running via LEDA on a PSP Slim, do not attempt to install either. For PSP-1000 users: in case the updater might fail, be sure to have a Pandora Battery and MagicStick ready.

------------------------------------------------------------------------------------------------

Also, Grab the OE firmware of your choice here.

------------------------------------------------------------------------------------------------

Hint:

Due to bugs in older OE firmwares, the most recommended version is 3.40 OE-A. In fact, 3.40 OE-A via TimeMachine is more stable. Note: Do not install OE at all, it is very buggy in fact (3.02 to 3.40 OE-A are full of bugs). Please use the latest version of custom firmware, and stay away from OE. Please use TimeMachine for your custom firmware needs.

------------------------------------------------------------------------------------------------

Here is the Generic OE installation guide, it applies to every OE firmware, but there are also guides specific to each version, scroll down below for the guide for your specific version.


Now, the steps on what to do:

1. Download an update of your choice.

2. Place oeupdmaker and oeupdmaker% into ms0:/PSP/GAME (ms0 is the MemoryStick Root.) If you are on a custom firmware, place the folders into ms0:/PSP/GAME150

3. Download the Sony Updaters for those firmwares here.

4. Place those Updaters into the oeupdmaker folder. 150.PBP and 3XX.PBP will be needed. (3XX.PBP is for the custom firmware you will be updating to.)

5. Then run the Update Maker from the XMB. It will create a DATA.DXAR, but
x3sphere said:
Please note: If you get an error message that says "Invalid SHA-1" when creating the DXAR do not proceed further. This means you have a faulty memory stick and a corrupt DATA.DXAR was created. Start over using a different memory stick.

6. Then copy the ###oeflasher and ###oeflasher% into ms0/PSP/GAME or ms0:/PSP/GAME150 if you are on a custom firmware. (### represents the specific OE version you are using or updating to.)

7. Place the DATA.DXAR found in oeupdmaker folder, and place into ###oeflasher folder that is in ms0:/PSP/GAME or ms0:/PSP/GAME150

8. Run the "OE Flasher" from XMB.

------------------------------------------------------------------------------------------------

Here are the guides for each specific version.
