    My US XT1768 did not have a notch here. I used my fingernails to pop the back cover off. Also, I followed this guide to successfully repair my US XT1768 in about 2 hrs. I’ve added a few comments below to point out the slight differences I found along the way

    • Insert an opening pick between the cover and the motherboard at the bottom right corner.

    • Slide the opening pick upwards to open the plastic clips.

    It was a bit tricky to pop the cover on my US XT1768 as there is a big tab near the battery compartment. Don’t force this tab. Instead, keep working on snapping the tabs loose on the headphone jack side of the cover. This worked for me.

    • Don't try to remove the motherboard all the way yet. The interconnect flex cable is still connected to its rear side.

    • Use a spudger to carefully lift the motherboard from the top and fold it towards the battery compartment.

    • Be careful not to damage any components underneath the motherboard.

    • Use a pair of tweezers to lift the earpiece speaker out of its recess and remove it.

    • When reassembling, be sure to properly orient the earpiece speaker such that the gold contacts are pointing away from the top edge.

    The earpiece speaker on the US XT1768 is larger and has the contact pins on the right side (viewed from the back as in the view shown here). Also there are two contact pads with textured conductive tape that need to be scavenged from the old part and applied to the replacement contact. One of these contacts the back of the camera, and the other is near the QR code sticker shown in the picture above.
