    Hi eros.palado.21

    Thank you for your reply. Sorry for the belated reply due to Lunar New Year holidays. Because your firmware version is not the latest version of Android 7, please update to WW-14.0400.1808.206 first. You may try auto-update or manual update.

    Then, download the first Android 8 firmware file WW-15.0400.1809.405 into the root directory of the internal storage. Reboot. Tap the system update notification.


    If you still can not upgrade your system, please tell me your update process or provide me a video for checking. :)
