Firmware Update - Fiio X3 Complete User's Manual

E. Firmware update
Firmware update may update the player with new features and optimize the playback experience;
not upgrading to the latest firmware does not affect current operation of the unit. The unit
supports firmware upgrades via update files loaded into micro SD cards. Improper operation during
firmware updates may cause the unit to malfunction! Please read the following instructions for
firmware updates carefully before proceeding.
To check the current firmware version:
From the main menu, navigate to System Settings->About X3 to see the current firmware version
loaded on your X3.
Preparations / Precautions before firmware update:
•A micro SD card formatted in FAT32 is required for firmware updates. This may be obtained by
formatting a card using the X3's built in formatting function (System settings ->Storage formatting).
CAUTION: all data and music on a card will be erased by formatting.
•A firmware update should not affect data on the micro SD card (other than any formatting
required, see above). Nevertheless, please back up any important data on your card to protect
against accidents.
•Make sure the X3 is adequately charged (preferably fully charged) for the update process to
prevent power failure during the update;
•Do not operate other buttons and dials on the player during the update process.
•If the update process fails, hold the power button for 10 seconds for a forced shutdown and turn
the player on in update mode again to resume the update.
