    • Remove the QR code sticker to reveal the screw.

    • Unscrew using a 0.7mm Hex screwdriver

    Screw is actually P2, not 0.7 Hex

    • Using plastic picks, begin to separate the frame from the internals at the corner of the phone containing the SIM tray.

    • Work around the top of the device placing more picks between the frame and the internals.

    • Once the top is removed from the Plastic frame work down the sides and remove the plastic frame.

    • The board level shielding was soldered to the board and required prying and breaking to reveal the chips.

    • Once the board level shielding was removed, the silicone thermally conductive rubber was scraped away from the processor.

    I don't understand why this step was performed.

    If you're trying to get to the screen, or another part of the phone I don't think it's a necessary step. I think it was done just to show a full phone teardown.

    Zack is right, this step is just to view and identify the ICs and parts on the motherboard. Do not perform this step if you wish for you phone to remain functional.

    Would you consider adding a section for separating the glass from the rest of the unit?

    • The antenna module is adhered to a daughter board with a soft sticky adhesive.

    • Remove the Antenna module by removing four T4 screws.

    • Remove the coaxial antenna cables by gently prying them up.

    • The Daughterboard and flex cable come out of the phone easily.

    • At this point we can see the USB connector is soldered to the board making replacement of this component expensive.

    This is also the microphone.

    The microphone is on the pcb located directly above to the usb connector (in the corresponding picture). It looks like a small rectangular piece of brass. It is actually quite common for the microphone on this particular Lumia to be turn up defective or not keep its connection, via the ribbon cable, firmly with the motherboard.

    • The battery is adhered quite strongly to the assembly.

    • A couple rounds of hot iOpener application followed by aggressive prying with plastic picks and metal tools was required to remove the battery.

I have a 1520 that we are have problems our of the ear speaker. The owner of the device brought it to us complaining of static in the audio. We replace the speaker and it worked fine but now she's back and the audio is out all together. No sound from the ear speaker. Loudspeaker works great so audio output is functional. Any clues or pro tips you can bestow? Thanks in advance.

I have disconnected the connector… I don't have any idea of how getting back to the motherboard..! Someone help plz

Hussein - Responder

It may be prudent to add a note to use the picks directly next to the back frame rather then just say from the corner. In my efforts to remove the back, I decimated the screen and now have to get a new one….
