If you can not update software via mobile app you should make it via USB.
Follow a few easy steps to update software:
- Connect device to PC using USB cable.
 - Start device in Soft Recovery menu (press and hold Volume Up button and short press the On/Off button at the same time).
 - Mount mass storage (navigate to 'MOUNT' using Left or Right navigation buttons and confirm with Action button).

 - PC should detect new mass storage device and LaMetric Time will be temporarily locked.

 - Drop the latest software file from firmware.lametric.com to the root folder of the disk drive that appeared on your computer.
 - Safely eject the drive from the computer and reboot your LaMetric Time (choose ‘REBOOT’ menu item by using Left or Right buttons and confirm with Action button).

 - The software will be installed automatically. The device will reboot few times.
 - In the case of issue - error file update.err.txt will be created on the disk. To check the error – mount disk again and open the file to find out the reason of the failure.
