The latest Android 5.1.1 Lollipop firmware is now available for the T-Mobile variant of Samsung Galaxy Note 4 with the model number SM-N910T. The update for the T-Mobile Galaxy Note 4 was rolled out Tuesday, a day after the Sprint variant of the handset began receiving the same firmware over-the-air (OTA).

The new firmware, which comes with the build number “N910T3UVU1DOFC,” is expected to include key security enhancements, including the fix for the Stagefright vulnerability, which allows unauthorized access to multimedia files or may potentially help an attacker take control of the microphone and camera of a vulnerable device.

To upgrade the T-Mobile Galaxy Note 4 to Android 5.1.1 through an OTA update, users have go to the “Settings” option on their device, tap the “About phone” option and then tap the “software update” option to proceed. Users, who are yet to receive an OTA notification, can install the firmware manually.

Here are some key aspects to know before performing the manual installation:

  • All personal data on the device must have proper backup
  • The handset should have at least 80 percent battery power
  • USB drivers for the Samsung Galaxy Note 4 must be installed on the computer
  • USB debugging must be enabled on the phone
  • Make sure that the device is a Samsung Galaxy Note 4 with the model number SM-N910T
  • Any recovery software or custom ROM installed on the handset must be removed
