Easily root T-Mobile Galaxy Light (SGH-T399) runs Jelly Bean Android 4.2.2

T-Mobile and Samsung introducing the new Galaxy Light (SGH-T399) with an unbeatable price, $0 up front and $59 monthly. This affordable yet powerful smartphone powered with 1.4 GHz quad-core processor, 1GB of RAM, 8GB of internal storage, Jelly Bean OS (Android 4.2.2), unlike other low-cost smartphone, it supports T-Mobile’s 4G LTE. For those who are interested to get the most out of this phone, you can try to get root access.


Fortunately, now superuser privileges can be obtained, thanks to shabbypenguin, a developer from androidforums. He makes Odin one-click root apps that can inject root exploits into our phones.

With root privileges on the T-Mobile Galaxy Light you can make some changes that could make your device have superior performance, such as removing various pre-installed apps or bloatware, with that we can free up some storage space, since we all know that this phone only has 8GB of internal storage.


  • Install the latest Samsung USB drivers for Windows, there’s no option for Mac or Linux, shabby’s tools on for Windows-based machine.
  • Grab the Odin one click from Shabbypenguin’s thread on AF.
