Usually, a carrier rolls out an OTA update within a few days of Samsung releasing the kernel source code. This time around, the manufacturer released the KitKat kernel source code for T-Mobile’s version of the Galaxy Note 3, which means that users on the carrier should be seeing an OTA update soon. An announcement might be forthcoming as early as Monday. As always, the kernel source code is of more use to developers looking to build custom ROMs for the device.
The baseband version of the KitKat build is N900TUVUCNB4, and you for you to be eligible to receive the update, you have to be on the latest software build. So head over to your device’s system info to check whether you already have the latest build installed.
