What you need

  1. Samsung Galaxy Note 4 Antenna Replacement, Midframe: step 1, image 1 of 1

    • Grasp the cap of the S Pen and remove it from its slot in the midframe.

    • Insert a plastic opening tool between the midframe and the display assembly.

    • Work the plastic opening tool around the perimeter of the phone to break the adhesive.

    • This adhesive is relatively weak, so no heat gun should be necessary.

    • Be careful to not separate the front glass panel from the rest of the display assembly, as it is still held together with adhesive.

    • Push on the battery housing to separate the midframe from the display assembly.

    • You will have to apply a reasonable amount of pressure to separate the two parts.

    • If your new midframe does not come with a headphone jack assembly, you'll need to transfer the one from the old midframe into the new one. It can be pried loose with plastic opening tools, as it is held in place with several plastic pins.

I broke the actual ports that the antenna cables connect to on the mother board. Is thereally away to fix them or do I have to replace the whole logic/motherboard? I would like to keep my logic/motherboard because I don't want to lose all my text messages. What should I do?

I also broke the connector component on the motherboard. It remains attached to the blue cable. Could this be re-soldered?
