1. How to upgrade the X5II?

A: ★Choose a TF card (Micro SD Card) with FAT32 file system. If the update process fails, pls change to use a blank TF card with capacity under 32GB, and directly format it by X5 2nd gen before the upgrade again.
★ The original file data in the TF card will not be corrupted when upgrading. 
★Ensure that the X5 2nd gen is sufficiently charged (preferably fully charged) before the upgrade to prevent power failure during upgrade.

Methods to Upgrading via TF card:
1. Choose a card with FAT32 file system.

2. Unzip the firmware upgrade package from FiiO and copy the X5II.fw (or x5ii.fw) file within to the root directory of the TF card.

★Do not press buttons or turn the dial on the X5 2nd gen while the upgrade is in progress.

5. When the firmware upgrade is complete, the X5 2nd gen will restart automatically.
