    Hi gomes.tisystem

    Thank you for your asking. Kindly provide the information below so that we can better assist you.

    1. Is your device JP SKU or WW SKU?

    2. Because the firmware version you upgrade is for JP (Japan) SKU, if your device is WW SKU, what is your upgrading procedure? I just put the JP-17.2018.2007.428 file into my root directory and nothing happened.

    The update procedure was done following the instructions on the ASUS website following all the recommendations
