New Upgrade issue I installed the 3.12 firmware update, but the PMU 0.2.0.4 will not install. Can anyone please help me fix problem? I connect everything up and it gives me this new version Available. I click on it and tells me download is successful, but when I hit the button upgrade. I get warning disconnect power or props. Leave battery connected and I select yes and it tells me upgrading, please wait. I then get a upgrade failure! please power cycle device and try again. Only to get the same error message. If I disconnect the battery before hitting the upgrade button, it ends the upgrade and closes the window. No matter what I do the upgrade always fails.
