and update” done?

Q: In the course of “UGW-linked download”, what will happen if the user downloads the
firmware before the service technician update the firmware downloaded with “UGW-linked
download” before?
A: The previously downloaded firmware in the method of “UGW-linked download” will be
overridden by the subsequently downloaded one.
This is because only one downloaded firmware can be held on the device.
The firmware downloaded in the method of “Service mode-linked download” and “UGW-
linked download” can be checked/deleted from User mode, but cannot be updated, so it
cannot be updated by the user unnoticed by the service technician.

service technicians. Before installing the individual response edition, ensure to obtain the

Q: If the device is down during firmware update, can the device be started using the older
firmware version?
A: No, it is impossible to start the device using older versions. If this occurs, the service

Firmware Installation" in chapter 6 of this manual for details.

Q: If the device is down during firmware download, is it possible to download the firmware
again?
