Install TWRP and Root Galaxy S6 on Android Marshmallow

Just a few days back Samsung broke the silence and started updating the Galaxy S6 to much awaited Android 6.0.1 Marshmallow firmware. Galaxy S6 owners, who also happen to be Android power users, they must have lost the root access and any custom recovery if they had it installed prior to updating their device to the Marshmallow firmware. A workaround to flash the TWRP 3.0 and also root the Galaxy S6 running Android Marshmallow has been found.

As we move ahead, we will go through a  comprehensive guide to install TWRP 3.0 recovery on our beloved Galaxy S6 running Android 6.0.1 Marshmallow. We will also get to root the device, but before rooting or flashing TWRP recovery, we will have to install a custom kernel to make the device rootable and flashable. The kernel we are talking about is the SpaceX kernel by XDA Senior Member Manh_IT. Once we are done installing the SpaceX kernel, we will be able to root the device easily and also install TWRP 3.0 recovery on it. Before heading towards the installation instructions, let’s go through some early preps to stay on the safest end.

  1. The guide here will work to root the Galaxy S6’s following variants only.
    • SM-G920F
    • SM-G920S
    • SM-G920L
    • SM-G920K
  2. Check your device’s model number under settings > general / more > about device. Do not try this on any other device as you will simply result in bricking it.
  3. Charge your phone’s battery up to 50% to make sure that your phone doesn’t die during the flashing process.
  4. Use OEM data cable to establish connection between your GS6 and your computer.
  5. Backup each and everything including your important contacts, call logs, sms messages. Also, copy your media content to your PC. This is important so that just in case you loose your data, you will already have it backed up.
  6. Disable your Windows Firewall, any Antivirus if you have installed. Also, close or uninstall Samsung Kies if you have installed it.
  7. Follow the steps to the letter to avoid mishap.

Required downloads and installations

  1. Download and install Samsung USB Drivers.
  2. Download and extract Odin3 v3.10.6.
  3. Download SpaceX-Kernel_MM.tar.md5 and TWRP-3.0_MM_ManhIT.tar.md5 carefully according to your device’s model number.
  4. Download SuperSU.APK file and copy it to your phone’s SD card.
  5. Download SuperSU.zip file and copy it to your phone’s SD card if you want to root via TWRP recovery. If are going to root using the kernel, then skip this step.
