Fiio X3 Complete User's Manual page 17

After the update process is complete, please delete the X3_Mark_Ⅲ.fw file from the micro SD card
and update the media library (System settings->Update Media Lib).
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 X3_Mark_Ⅲ.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 10 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 X3_Mark_Ⅲ.fw file in a micro SD card
of 32GB or under, formatted using the X3's built in formatting function (System settings->Format).
CAUTION: all data and music on a card will be erased by formatting.
There is no need to update each firmware, and please just load the latest firmware and
•
upgrade the X3 directly.
