Since T-Mobile has always been a root-friendly carrier, it has been hard for T-Mobile users to know that their Galaxy S7 or S7 Edge couldn’t be rooted because of the locked bootloader on S7 variants with Qualcomm processors.

However, things dramatically changed yesterday when an engineering bootloader for Qualcomm based Galaxy S7 and S7 edge devices leaked yesterday, which allowed root files to be installed simply via adb only.

Grab the engineering bootloader, Odin (customized) and the SuperSU beta zip from the downloads section below, and follow the instructions carefully to root your T-Mobile Galaxy S7 and S7 Edge.

    4. Click the Start button on Odin and wait for it to finish the process. Once it has finished successfully, you’ll see a pass message on the Odin screen.
    5. Your device will automatically reboot when Odin is done flashing. You can then disconnect your device.

    1. Download the SuperSU S7QC .zip from the downloads section above, and unzip it on your PC.
    2. Setup ADB and Fastboot on your PC.
