T-Mobile HTC One Receiving Update to Build 1.27.531.11 – Still Android 4.1.2

The HTC One on T-Mobile will start receiving an update as early as this morning that will improve stability, LTE connectivity, and reception, plus enhance a couple of processor issues. The update is to build 1.27.531.11, and is 247MB in size. Unfortunately, it does not appear to be the 4.2 update that has been reaching international variants of the device over the last week or so. Once you have updated, you’ll still be running Android 4.1.2. 

To update, you can wait for the update to pop-up on your device, or sideload it through HTC’s website.
