Firmware upgrade, factory data reset and technical
support
1. How to upgrade firmware?
The M17 supports online upgrade and local upgrade.
Online upgrade
If a new firmware is available and can be detected (with the M17 connected to an available
internet), an upgrade notification will show up in the notification center. Tap on it to enter the
update menu for the online upgrade. If there's no upgrade notification showing up, you can
go to the "Technical Support->Firmware Upgrade" menu, and tap the "Check for updates"
icon to check manually.
