    for me to run HEN D and Devhook to put my PSP from 2.71 into 1.50 (i can do that already) and then from there, use the 3.40oe easy installer to upgrade my FW to 3.40oe?

    Is that actually possible or do you have to have 1.50 FW properly installed before you upgrade to 3.40oe?

    You have to have the firmware 1.50 installed.

    All OE versions use it as a base to install and need it's ability to access the firmware as well as running custom applications as it installs.

    All OE versions are actually fusions of that 1.50.
