Introduction

Use this guide to replace the headphone jack/micro USB board on your HTC One M9.

Insert a microSD card eject tool or a paperclip into the small hole in the microSD card tray, located on the upper right hand side of the phone above the volume buttons.
  • Insert a microSD card eject tool or a paperclip into the small hole in the microSD card tray, located on the upper right hand side of the phone above the volume buttons.

  • Press to eject the tray.

    • This may require a significant amount of force.

  • When reinserting the microSD card, ensure that it is in the proper orientation relative to the tray. The contacts should be inserted first and face to rear side.

  • It is normal, that the microSD card doesn't stay on it own inside the tray. It is also not completely trivial to place it correctly flat inside the tray.

Insert a SIM card eject tool or a paperclip into the small hole besides the SIM card tray, located on the upper section of the left edge of the phone.

  • Using a plastic opening pick or a spudger, gently pry and remove the top of the case.

  • Remove the two 4mm T5 Torx screws on the top of the case.

Be sure to remove the SIM tray and memory card tray prior to removing back case! Bent mine because that step was missing.

The black plastic piece that runs across the top is very thin and is stuck on with very strong tape.

  • Work a plastic opening pick around the perimeter of the device to separate the rear case from the display assembly.

  • The SIM card tray and Micro SD card tray must be removed before the back cover can be removed.

  • Be careful around the power and volume buttons, as they are fairly delicate.

  • Be careful when separating the body from the display assembly, as the rear-facing camera may be stuck to the body with adhesive.

The SIM Card and SD Card's need to be removed before the case will come apart.

I found a video showing someone using a 2 to 3 inch length scraper razor blade around the perimeter. On my second HTCM9 battery swap I found that leading with a square tipped X-Acto blade to begin the opening, and leaving the trailing, “already opened” gap “wedged” open with the scraper blade helped smoothly open from top (IR header) to bottom (micro USB charger port). A conventional spudger pries open too quickly and can damage and misshape the LCD’s soft bezel. The bezel surround is a much softer compound than the rear case. You can work the rear case loose by gently prying the back’s perimeter outward and occasionally inward as you progress. There are four tabs on the LCD assembly (i.e. nearby and under the pliers in step 5) on each side that protrude into the rear case. Push in toward the back, and pry outward on the back case seam around the vicinity of the tabs. This action provides clearance for the tab to loose from the case tab slot.

  • Use a pair of tweezers to disconnect the blue and white antenna cables.

  • Remove the two 1.5 mm Phillips screws securing the battery connector to the motherboard.

When reassembling the phone, be sure to attach the battery connector correctly before screwing it down. It has a rectangular connector that may not seat correctly if simply screwed down.

  • Use your fingers or a spudger to disconnect the ZIF connector.

Lift up on the white portion of the connector

  • Use a spudger to disconnect the bottom speaker ZIF connector, sliding the cable out of the socket.

  • With the tweezers, carefully lift up on the tape covering the electrical strip shown in the picture.

  • Be careful with the tape, as it can tear easily.

  • Use a spudger to disconnect the ZIF connector.

Mine did not have the piece of tape.

  • Disconnect the remaining three ZIF connectors.

  • The third ZIF connector is mostly underneath the motherboard. When reassembling your device, make sure it is placed back underneath.

For the featured ZIF header in step 10, which originates from under the circuit board, after liberating the yellow-clear tape I used a “Plackers” dental flosser “pointed end” to carefully lift up from under the ZIF ribbon.

  • Remove the three 4 mm T5 Torx screws securing the motherboard.

Great guide just one crucial warning missing! When removing the battery which is underneath the power/SD/volume cable make sure you see that and carefully remove the battery without tearing it apart! Had to learn the hard way. Fortunately it's replaceable..

  • Use a pair of tweezers to gently lift the vibrator off of the motherboard.

  • Use a plastic opening tool or your hands to pry the motherboard out of the case.

    • The motherboard is secured with adhesive, so you may need to use an iOpener or heatgun to loosen the adhesive. Refer to the iOpener guide for info on this.

Mine did not have any adhesive.

  • Remove the 3 mm T5 screw that holds the front speaker in place.

    • This screw was missing due to mishandling in an earlier deconstruction.

  • Gently remove the speaker from the device.

  • Use a pair of tweezers to remove the headphone jack/micro USB board.

The antenna wires must also be removed from the USB/headphone Jack board. Verizon phones will have only one blue wire but the new board will have two plugs for two wires. Use the outboard plug to connect the wire
