I was getting hugely frustrated trying to upgrade the firmware on mine to Android 5 (kept on getting stuck at "waiting for device"). I was using a Surface Pro 3 (Windows 10) and eventually came across a posting somewhere suggesting that flashing might not work via a USB 3 port. I installed the Yota firmware flashing tool on an ancient Dell desktop (Windows 7) that barely has USB 2 let alone 3 and it worked first time.
