Step 4. Open the back cover

We use a plastic tool to pick up the back cover. With light movements up and down, we pry to try to open the cover. The sealant has dried and literally welded the cover, so it will take some time to remove it.

Step 5. Disconnect the connectors

We disconnect the display, touch screen connectors and a connector of the small circuit board with a non-metal tool. We still have the motherboard powered by the battery, so we have to be careful.

Step 6. Unscrew the screws

Using a Phillips 1.5 mm screwdriver or #000, unscrew the two screws holding the motherboard, bracket and battery together.

If the screws are different: ℹī¸ī¸ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its parts. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Step 7. Remove the motherboard

Carefully pick up the Bracket (we call it Bed) and take it out. The cables will interfere with us a little. We have to put them through the rectangle hole in the Bracket.

Step 8. Unscrew one screw

Now we need to turn the Bracket over and unscrew one screw holding the motherboard and Bracket. We think it is a solution to press tight the battery pad and spring contacts on the motherboard. We use Phillips 1.5 mm screwdriver or Phillips #000.

Step 9. Disconnect the battery connector

We need to slightly separate the printed circuit board from the Bracket to lift and detach the battery contact pad. We have to disconnect the battery this way because there are spring contacts on the circuit board, and the battery cable with a platform for these contacts is pressed against the Bracket.

Only after that we can detach the cable of the side buttons. The cable is glued a bit. We need to gently pry it with a thin tool and bend it up slightly.
