You run the Update Maker, but you have to make sure you have the 3.40 Update named "340.PBP" and the 1.50 Update named "150.PBP" in the oeupdmaker folder. once it's done, it will have generated a "DATA.DXAR". You need to move that file into the 340oeflasher folder and execute the 3.40 Firmware Install
This may be explained when I actually get my hands on the PSP, but -
"You run the Update Maker"
I'm assuming that's the EBOOT.PBP file in the "oeupdmaker" directory? What about the oeupdmaker% directory, what is that?
"and execute the 3.40 Firmware Install"
When you have all the files in the correct places and have done all necessary steps before this, does an icon for the 3.40 firmware install show up in the PSP's main menu?
-and one last question:
I have both original Sony firmwares, but the v1.50 one is called EBOOT_1.50.zip, whereas the 3.40 is named PSP_340_UPDATE.rar. Am I right in thinking that the 1.50 file is the official Sony update just like the 3.40 one, even though the naming of the files varies?
Thanks.

Thanks. I'll report back next week with the results of the flash; hopefully everything goes well.
(do you run the *patched* firmware update from the cross media bar?)
The firmware will be on to the flash. So itll come up just like you regular firmwares do, you dont need to load anything to use your new firmware.
