How to upgrade the M3 firmware:
Before updating:
1. Please ensure that the M3 is adequately charged, preferably fully charged, before updating the firmware, to prevent loss of power during the udpate.
2. You can only enter the shortcuts menu and from there the settings menu and the firmware update option by holding the menu button from the Now Playing screen. Therefore, please load the M3 with at least one song and play a song before attempting to update the M3.
3. You may go to Settings->Player information (first option, third / last page) to check the firmware version of the M3.
To update the M3's firmware:
1. Extract and copy M3.hex to the root directory of the ***internal storage*** of the M3. (M3.hex may simply appear as "M3" on your computer.)
i.e. drag the M3.hex file directly from this package onto the drive icon of the M3 internal storage (called "FiiO" by default, volume size 7.xx GB)
2. While playing a song on the M3, in the Now Playing screen, hold the menu button (upper left button on main panel) to open the shortcuts menu; choose and select the cog icon at the bottom to enter settings menu; click "up" once to choose "Auto upgrade" at the end of the System settings menu and select it to update the firmware, select the tick to confirm;
3. The M3 will update its firmware and then reboot;
4. Choose your preferred language for the M3 again.
