The Samsung Galaxy S6, S6 Edge and the S6 Edge Plus are being updated to the latest Android 6.0.1 Marshmallow Samsung TouchWiz firmware officially. The update has already reached the USA, some parts of Europe and South America and now the SM-G920I and SM-G925I, which belong to South Asia, Australia, New Zealand and South America, are being updated. So if you have already updated your device to Marshmallow then gaining root privileges may also interest you. Yes, courtesy of XDA forum member, arter97, the root is now possible for the two devices on the official Marshmallow build from Samsung. There is a bit workaround to this procedure. First, you need to install the TWRP recovery (custom recovery) and then flash a kernel that best suits your needs and SuperSU package as well. The SpaceX kernel brings some features to the device like the Busybox, private mode, deep sleep fix, and much more. Arter Kernel may or may not contain these features but can successfully root your device. A similar root has also been brought to the Samsung Galaxy Note 5 on Marshmallow which roots and fixes the deep sleep. Before you proceed, make sure you are on Marshmallow ROM on Galaxy S6 or, at least, have the Marshmallow bootloader. You may also root the devices with CF-Auto-Root. Link at the end.
