After rolling out the Android 7.0 Nougat (Sense 8) update for the unlocked variants of HTC 10, the company now starts rolling out Android 7.0 Nougat update for the unlocked HTC One M9. The OTA update comes with software version 4.14.617.6 and to get the OTA update, your HTC One M9 should be on software version 3.35.617.31. If you have any issue updating via OTA, you can manually install the OTA update or flash full firmware (RUU.exe).
In this guide, we will let you know how to update HTC One M9 to Android 7.0 (Sense 8) manually. The manual installation method is simple. If HTC One M9 is running on software version 3.35.617.31, you can simply update it to Android 7.0 (Sense 8) (software version 4.14.617.6) in recovery. Or you need to flash the full firmware (RUU file).
The Nougat Sense 8 update brings new features like multi-window mode, better battery management, redesigned notification experience, Direct Reply, redesigned Settings menu, and more. However, it seems that this update will not fix overheating issues of HTC One M9.
