вот китаесы сегодня прислали ответ на вопрос кому интересно. Тоесть, чтобы обновить девайс с новой авторизацией надо прибор отсылать обратно в китай :(
dear friend,
thanks for your question. several weeks ago, the buyer just tell device's SN, when he pay the softwate, we can add it. but now, if you want to add software, you should send it back to us. and the just software price is same as a set of device. so if you want to have the other software, you can buy a set of device. the device's selling point is software, wish you understanding.
