Earlier today, HTC released the One M9 Nougat update for carrier-free unlocked sets around the world. The update is being pushed out gradually to all such One M9 sets world over, but if you don’t like waiting for it too much, then you can download the OTA file of the update from below and upgrade to Android 7.0 and Sense 8 yourself right away.
First things first though, for this to happen successfully, you must be on software version 3.35.617.31 right now, as this is the base version for the update. Also, in case you are on 3.35.617.21, not on .31, then you can use this OTA file (size: 91.17MB) to update from .21 to .31, on which Nougat OTA would work. Install the OTA file the same way as provided below for the Nougat OTA version 4.14.617.6.
Further, your One M9 shouldn’t be rooted or doesn’t have any changes made to system partition. If there were any changes made or something, then you need to go back to stock first. And of course, you are gonna need stock recovery for this.
However, if you never installed TWRP recovery or never rooted your One M9, you are good to go. Just make sure you are on software version 3.35.617.31. If not, then check for the update now, and you should receive the .31 update immediately as it’s quite old now.
