2.What if X7MKII couldn't recevie firmware update notification?
First of all, please make sure the WiFi is connected and the network is working. After that, please go access to "Technical support>Firmware update>Online update" and update the unit. If no new firmware detected, please download it from our website to internal storage or microSD1 and upgrade it following our instructions.
If no new firmware detected, please kindly contact us. Normally it's something wrong with out server and it has nothing to do with the firmware.
