Next, remove the battery housing/protective cover using a Phillips #00 screwdriver.

Use the Phillips #00 screwdriver to remove the screws securing the protective housing to the smartphone. There should be fourteen screws measuring 3 mm in length and one screw measuring 6 mm.

Three of the screws will remain attached to the protective housing and can be identified by a metal plate underneath them. In total, there are 18 screws.

After loosening and removing all the screws, use the pry tool and tweezers to lift the housing along the edges. A sticky pad will hold the housing to the smartphone, do not hesitate to give it a firm tug until the housing separates from the sticky pad.
