Local upgrade
Also, the M21 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
M21 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.
2.Before the upgrade, ensure the power of the device is adequate (>30%) so to
avoid upgrade failure.

reason may be that the firmware file is damaged. At this time, press the power
button to reboot the device. Re-download the firmware file and restart the
upgrade.
2.Force to reboot
Please hold the power button for around 10 seconds until the "FiiO"logo shows
up.
