The HTC One M9 was among the first handsets from 2015 to be updated to the current Android 7.0 Nougat OS, but this was only true for the unlocked variant.
Somewhere in March, the locked models started receiving the Nougat treat, but again, this was kind of limited to the American market. Since then, we’ve seen quite a number of regions receive the treat, but it’s only now that those in Asia can now get the update on their HTC One M9.
As expected, the update is hitting the HTC One M9 as over the air. It carries software version 4.23.425.1 and other than coming in with the latest Android 7.0 Nougat OS, it also packs a bunch of system performance enhancements, bug fixes as well as the latest monthly security patch from Google.
Since it’s a major update, it is quite heavy, weighing a massive 1.5GB. With this in mind, the Taiwanese company recommends that you connect to the internet using a Wi-Fi hotspot in order to avoid additional data charges from your carrier. As noted earlier, HTC One M9 users will be receiving the update over the air. This means that not every user of the phone in Asia will be receiving the treat at the same time, rather, the update will be rolling out in stages, with some set to get the OTA notification later in the week.

If you feel like waiting isn’t part of your DNA, you can try and do a manual update. This requires that you visit the Settings app of your HTC One M9 and tap on the About phone option at the bottom of the menu. Next tap on the System update option and from there, you should be able to check for updates manually.
If the files are ready for your One M9, make sure that there’s at least 50% of battery juice before proceeding with the update, otherwise, find a power source and keep the phone charging during the entire time of the update.
