The tabs should be 4 spaces lines like 137 to 155 tabs are excessive, but that is a quibble. Same quibble for dlprogress.py

If it was a more complex script and the code matbe translated to other languages then the you should use unicode string.
Example:
        rootfs = "quantal-preinstalled-phablet-armhf.zip"
        androbase = "quantal-preinstalled-armel+%s.zip" % (device)

changed to:

        rootfs = u"quantal-preinstalled-phablet-armhf.zip"
        androbase = u"quantal-preinstalled-armel+%s.zip" % device

OR

        print("Downloads are finished! Now make sure your device is connected with USB Debugging activated.")
to
        print(u"Downloads are finished! Now make sure your device is connected with USB Debugging activated.")
