简介

Is 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 iOpener 指南 during this step.

Before beginning, make sure to power off your phone completely and disconnect from any external power source.

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!
