HTC One M9 Motherboard Replacement
Introduction
Passez à l'étape 1Is your HTC One M9 device not booting up or is it experiencing random lock ups and freezing issues? This indicates that the motherboard is damaged and needs to be repaired. A motherboard is basically the foundation of any electronic device and plays a significant role connecting every component in the device. While repairing the motherboard is possible, this guide emphasizes on replacement when the damage is too severe and is beyond repair.
A motherboard is susceptible to damages due to overheating, electrical damage, contact with fluids or heavy impacts. A malfunctioning motherboard is more likely to exhibit these symptoms:
- Burning smell
- Unresponsive device or freezing issues
- Components of devices are not working properly
Before using this guide, be sure to verify the working condition of the battery and the screen of your phone. Dead battery or screen can result in booting issues. Use this link to troubleshoot your phone if it doesn't turn on: HTC One M9 Troubleshooting
Step 8 requires you to apply heat using iOpener to loosen the adhesives. Refer to the Instructions iOpener during this step.
Before beginning, make sure to power off your phone completely and disconnect from any external power source.

The microSD card tray is located on the upper right hand side of the phone, above the volume buttons. To open the tray, insert a microSD card eject tool, or a paperclip, into the small hole in the microSD card tray.
-
Then press the tool or paperclip to eject the microSD card 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.
-
Press to eject the tray.

Using a plastic opening pick or a spudger, gently pry and remove the cover on top of the case.
-
Remove the two 4 mm T5 Torx screws on the top of the case.

-
Work a plastic opening pick around the perimeter of the device to separate the rear case from the display assembly.
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 get underneath the white and blue cable connectors and gently push them upwards to disconnect them.
-
-
-
Remove the two 1.5 mm screws that secure the battery connector to the motherboard, using a Phillips #00 screwdriver.
-
Use a spudger to gently pry up the battery connector from its socket.
On my new battery the connector was not aligned precisely so the battery was not connected properly to the motherboard after screwing it in. The connector is supposed to hold on it’s own without the screws. If the connector does not hold to the motherboard without the screws, make sure that the connector is actually plugged in properly and only screw it in once it holds by itself.

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..

Not really that hard!
Well, i repair phones everyday and HTC is always a difficult brand, but I would rate the M7 as harder to repair than the M9.
The only part that should be very very remarked is while lifting up the motherboard, if you don't warm the adhesive it will be very difficult to get it out of the case, yesterday I did one and broke 1 led of the notifications leds!
do u have any m9 motherboard for sale? I am searching for one
No sir, i don’t sell any parts for any phone.
After messing with the HTC 10 i must say that’s my most difficult HTC to do as of yet, a nightmare!
