Remove the power and volume flexible cable

The removal of the flex cable for the buttons of the Huawei P20 lite is a little more tricky.

1. First loosen the black plastic cover over the flex cable.
2. Heat the contact field glued in the device to make it easier to loosen.
3. Use a thin tool such as a steel spatula to slide it under the gold contacts to loosen them.
4. Then remove the cable from its hole by warming up the glue and driving with the spatula on the inner side between the cable and the frame.
