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.
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?
