How to manually update your Google Play edition HTC One to Android 4.4 KitKat

Manually updating your GPe HTC One to KitKatis surprisingly easy

Android 4.4 KitKat is here for the Google Play edition HTC One, and as usual it's slowly rolling out to certain handsets via an over-the-air update. But as tends to be the case with some OTAs, not all devices are receiving the update right away. Fortunately there's a relatively easy way to manually load the update onto your device we've got a step-by-step guide after the break, and the process is actually a bit easier than the usual method of "sideloading" updates. The entire process can be done on the device itself, without connecting it to a computer.

Check past the jump to get started.
