A few days ago AT&T pushed Android 4.4.2 to its version of the LG G2, and now it's T-Mobile's turn... sort of. No, an OTA isn't hitting the airwaves just yet, but that doesn't mean T-Mobile G2 owners can't get their hands on the OS update right away. A full 1.5GB ROM has found its way from LG's servers to the XDA forums, and it's open for anyone to get their hands on. You can download it directly here.
A screenshot is provided. As you can see, this is indeed Android 4.4.2. The build number is KOT49I.D80120a.
After downloading the ROM, which comes in the form of a .kdz file, you can upgrade using the LG Mobile Support Tool. If you would prefer to wait, you can take this as a sign that your OTA update isn't too far off.
Thanks, Dinesh Nalluri.
