Hi! I bought an alarm system Medion MD90770. When i installed a system, there was a firmware update. After firmware update, there wasn't a possibility to change admin and silent pin. Reset to factory default and deleting/installing app don't work. When i tried to do something with this problem i pushed a sos button by mistake and now alarmsystem is turned on all the time. PIN does't work. What can i do in such case?
