Introduzione

If primary functions of your ZTE Blade X Max are failing—failure to power on, multiple functions failing—and you have gone through the troublshooting guide, then you may have to replace your motherboard.

This guide requires removing the back of the phone, which is not meant to be removed by the consumer. You will have to use heating products to complete this guide. If you are using the iFixit iOpener, or a heating pad, be sure to follow the instructions for that particular product.

    • Slide the Jimmy along the under backing and lightly push the plastic up.

    • You will hear a snapping sound as you slide the Jimmy along the backing. This is from the closures releasing. There should be seven total closures on either side of the device, and three on the top and bottom.

    • Carefully remove the backing from the phone once the closures are released.

    • If you do not open all of the closures on the backing do not attempt to pry it off.

    • Be careful when opening the back of the phone. The fingerprint scanner is connected by a thin film that will tear if pulled too roughly.
