Users on T-Mobile who have the Moto X will be pleased to learn that the Android 4.4 KitKat firmware has been leaked for the device. According to the reports, the version is fully functional although it is missing a few elements. We will provide a source link below for you to check it out, but as always we recommend caution with newly leaked firmware. Be careful to backup your device and follow any instructions carefully if you want to try it out.
It is probably not too surprising that KitKat is close to availability for the Moto X... after-all, Motorola is a subsidiary of Google now. It shouldn't be too long before we start to see fully fleshed out ROMs for the T-Mobile Moto X using Android 4.4. We'll keep you posted when we find out anything new.
