You should know that T-Mobile HTC One M9 is receiving the latest Android 5.1 Lollipop update, I talked about it about a week ago:

As you see, a single firmware file is OTA.zip file, there is not full RUU file.

Well, I feel lucky, HTC officially post full RUU file for T-Mobile HTC One M9’s 2.7.531.6 Android 5.1 Lollipop update.

RUUs Download Directly

  • RUU_HIMA_UL_L51_SENSE70_TMUS_MR_TMOUS_2.7.531.6_R4_Radio_01.01_U11440601_81.03.50702G_F_release_445023_signed_2.exe

How to use RUU firmware file? This is really quite easy:

  • Install HTC Android USB Driver to your computer
  • Connect your T-Mobile One M9 to your computer. At this point, you need to use Windows computer, because the RUU firmware file is factually an exe executable program file
  • Your One M9 phone will be recognized by the computer
  • Once the phone is properly recognized on the computer, locate the RUU.exe file that you downloaded to launch the system update wizard

If your phone can’t be recognized, please boot your phone to Download Mode and fully restart your RUU installation.

If you need, there is also a full guide for you.
