    • Use an opening pick and place it between the plastic back cover and the metal housing near the buttons.

    • Push the opening pick into the gap to separate the back cover from the housing.

    • Don’t remove the back cover all the way yet. There is a cable connecting it to the motherboard.

    There is a glue-ish gasket keeping it closed. I used an exacto knife to start it opening.

    • Remove the core assembly.

    I had to remove that screw on the core assembly using a Phillips 000. When I initially tried lifting, the core assembly started to bend. Mine also has a connector under the core assembly near the thumb in the picture. The connector goes from the underside of the core assembly to the screen/body. It prevents me from removing the core assembly as I'm not sure how it should be removed examining it

    Louis Finney - Yanıt

    This step is really difficult, and I'm still not sure it was necessary. The core assembly is really packed in there, and it took me several attempts, lifting from various corners. Don't pull by the circuit board. It will bend if you're not careful. You've got to get under the core assembly. I had the most luck starting next to the display connector at the top, then moving to the sensor on the other end of the board (barometric sensor), then moving to the speakers on the left, and finally lifting from multiple points once it was out far enough. In really hoping I didn't damage anything.

Hi, I am having issues with bluetooth, is it a replacement or do I need to swap the MB? Thank you

Bruno Albin - Yanıt

When you have ruled out any software issues (tried restart, factory reset, software update, etc) then this is most likely a MB replacement since all the modules are integrated on that tiny thing.
