okay THATS weird, my string reads 2017092621 at the end o.O
so that means you already updated?
sadly i cant force the api to return something with using your version string
curl --data "model=Boyue-Icarus-T80S&packageDate=2017092314&packageCode=Icarus-Ereader_V1.0.0-2017092314&serialNumber=your serial"
