Creating the 3.40OE DATA.DXAR
From the 340oe_a.rar file you downloaded copy the oeupdmaker and oeupdmaker% folders into:
After doing so copy the 340oeflasher and 340oeflasher% folders into:
Copy the 1.5 Update renamed to 150.PBP into:
Also copy the 3.40 update renamed to 340.PBP into:
Note: On pre-existing DAX custom firmwares, you may use the GAME150 folder as a guaranteed fool proof method (see Recovery Menu concerning GAME folder settings). Either way will work however, but this way has better success for some people.
Now exit to the the PSP and enter the Game menu and start the OE UpdateMaker.
A bunch of white text will come up.
Once it finish (takes about 3 or so minutes on Sandisk memory sticks, Sony and Lexar ones may take upwards to 45 minutes.), it will return to the XMB. Once again connect your PSP to your PC via USB. There will now be a new file in PSP/GAME/OEUPDATEMAKER, named "DATA.DXAR". If it has the size of zero bytes, redownload the 3.40 and 1.5 updates, and start the whole process over.
Navigate to PSP/GAME/OEUPDATEMAKER
, and move the newly created DATA.DXAR into:
Flashing 3.40 OE-A
// TAKE OUT ANY UMD THAT IS IN THE DRIVE!!!
Make sure your battery is at least 75% (100% recommended) and plug the AC adapter. Navigate to the Game menu on the PSP and start the application named 3.40 OE-A Firmware install
. Howeveer, if you want to take a chance with a less amount of battery when starting the program hold L and Triangle to bypass the battery check.
It will display some pink text, press X
, and it will start flashing your psp. A percentage will be displayed.
When it finishes, you will be prompted to manually restart your PSP. You can now delete the update files off of your memory stick.
[FIELDSET="Recovery and Homebrew"]
Turn your PSP off, and turn it back on, holding the 'R' trigger button. The PSP will enter recovery mode.
Scroll to configuration, and press X
Scroll to Game folder homebrew
, and press X
until it displays "(currently: 1.50 Kernel)".
Note: You may also disable hide corrupt icons and disable SCE logo. Also, you may notice that your recovery menu is now a different color than previous DAX custom firmwares. This is normal.
