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.
Local upgrade
Also, the M17 can be upgraded locally by a firmware package. Download the firmware
package file from FiiO website, and copy it to the internal storage of the M17 or an SD card.
Go to the "Technical Support->Firmware Upgrade->Local Upgrade" menu, and find the
firmware package file to start the upgrade.
Notes:
1. Do not unzip the firmware package file.
