    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.

    https://www.asus.com/support/FAQ/1009748

    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. :)

    Hi majid.info

    Thank you for your asking. Please note that we do not provide the official unlock tool for ZC521TL. Furthermore, please note that unlocking the device or flashing the custom ROM are quite risky, may causing security issues like Widevine Issue, banking app usage issue, or unexpected software issues. Sorry for any inconvenience it may be caused. Thank you for your continued support and patronage.
