Firmware Update - Fiio X3 Complete User's Manual

C. Firmware update
Firmware updates 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 6 seconds for a forced shutdown and
turn the player on in update mode again to resume the update.
Summary of micro SD card upgrade procedure:
1.Copy the X3II.fw file provided by FiiO into the root directory of a micro SD card in FAT32 format;
2.Turn off the X3 and insert the card into the slotof the X3 (if not already inserted);
3.Hold the power button while holding the Shortcuts key (upper left key of the X keygroup) to

and update the media library.

In case of firmware update failure:
•If "update file not found" is shown, please check to make sure that the micro SD card is
formatted in FAT32 and that the X3II.fw file within the firmware update package was extracted
and placed in the root directory of the card (e.g. by dragging the file directly onto the drive
icon of the card on your computer).
•Otherwise, if the update process fails and error messages are shown, please hold the power
button for 6 seconds for a forced shutdown and turn the player on in update mode again to
resume the update.
•If the update process fails repeatedly, please try putting the X3II.fw file in a micro SD card
of 32GB or under, formatted 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.
