Worked for me on my 2013 TE. This is probably the 3rd (or possibly 4th) time I've done an Entune system upgrade since I've had the vehicle, always without incident.
2013 TE here too...never any issue with an update.

1. What should be on my USB memory Device
1) Download the update file contents onto your computer.
2) Double click on the file, which should open a new folder with a file named "SWDL.iso" inside it.
3) Insert your USB flash drive into an open slot on your computer and open a view of your flash drive as a new folder.
4) "Drag and Drop" the "SWDL.iso" file to the folder representing your USB flash drive.

1) For this and all following steps, keep your vehicle parked in a well-ventilated open area outside, suitable for running the engine, not in an enclosed structure such as a garage.

Note: Turn on the Radio.
3) Press the “Apps” button (the system will switch to the Apps main page).

Refer to your Owner's Manual "Using the audio system; Operating a USB memory" section for the precise location in your vehicle.
