    Finally managed to get the updater to run after disconnecting everything but my fingers from my macbook pro (2014 15″ retina 16GB 10.10.5 Yosemite) and received the following error: “ERROR: Firmware update failed. Error Code: 0xE3FF8003

    I’m keen to get firmware updated before our tour kicks off.

    Any suggestions?

    Hi Andy,

    Can you please check the following things:
    -When does the error message pop up:
    –> When bargraph on device has completed?
    –> Right when the download is started?

    -What firmware version was on your device before you tried to update?
    -What firmware version os NOW on the LP16?
