The T-Mobile Galaxy S5 G900T

The T-Mobile Galaxy S5 G900T is a version of Samsung’s flagship Galaxy S5 that is carrier locked to T-Mobile.  In this post, we’re going to show you how you can get root access on this device by using CF- Auto Root.

Prepare your device:

  1. This guide is only for use with the Samsung Galaxy  S5 G900T.  Check your device’s model number by going to Settings> About
  2. Charge the battery to at least over 60-80 percent.  This will prevent you from losing power before the process ends.
  3. Back up all your important contacts, SMS messages, and call logs.
  4. Have a back up of your Mobile EFS Data.
  5. Enable USB debugging mode
  6. Download USB drivers for Samsung Devices

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
