How to upgrade the X7 firmware:

- Ensure that the X7 is adequately (preferably fully) charged before attempting to upgrade.
- Copy the update downloadable “X7 update.zip” file into the root directory of a FAT32formatted micro SD card in the X7 (or root directory of the X7's internal storage).
- With the SD card in the X7, turn on the X7 in Android mode and select “Support” > Upgrade > external_SD (or internal_SD if you put the file in internal storage) and select X7 update.zip. The following dialog appears:”Confirm upgrading firmware with selected file?” “Cancel OK”
- After clicking “OK”, wait patiently and do not operate the X7. The X7 will automatically restart and enter firmware update mode.
- After the firmware upgrade is complete, the X7 will restart again in normal android mode for use.

Notes and precautions:

- If attempting upgrade using SD card, the SD card should be formatted in FAT32; if upgrade fails, try using a card of 32GB capacity or under, format it using the X7 (back up data on the card first), copy X7 update.zip inside again and attempt upgrade again.
- If attempting upgrade using internal memory, there needs to be adequate free space (preferably over 1GB); copy X7 update.zip to the internal storage and select “internal_SD” for the upgrade.
- Do not push the X7's buttons while the upgrade is in progress.

About Music Players:

In case your device has encountered various problems that this release can fix, or if the same release comes to add certain features that you can make use of, then you should definitely take into account upgrading.

Usually, to do that, you must get the downloadable file (unpack it if necessary) and transfer it to the player through any available method, and start the upgrade process from the device’s setup menu.

However, given the large variety of music players and the many ways to enter update mode, it would be best if you read the product’s installation guide and initiate this task only when you have familiarized yourself with the steps.
