Root and TWRP on Galaxy S6 on 5.1.1

The Samsung Galaxy S6 which is the latest flagship device from the Korean giants has been receiving firmware updates for an Android 5.1.1 upgrade. This has been a huge step for the company who has often been criticized for delaying firmware updates for its flagship devices.

The 5.1.1 update which was first released by T-Mobile in the US, is now officially being seeded to almost all the other variants as well as the international models. The 5.1.1 update brings you the ability to remove some of the toggles from the Notifications drop-down panel such as Quick Connect and S-Finder which weren’t that frequently used. Along with RAW support, lower ISO values and manual control of the shutter speed to the camera sensor there is also a huge improvement in the TouchWiz interface. A lot more emphasis has been given on Material Design in the elements. And most importantly Samsung has fixed the RAM leak.

But one of the many drawbacks of the 5.1.1 during the time of the release was that it wipes away the root and custom recovery installed on the device. But after extensive efforts by xda developers bigbiff and g.lewarne, we finally have a working method to obtain root privileges using the S6 UniKernel. It has a built in auto-root which grants you permissions to use root applications such as Titanium backup etc. Along with root you also get the ability to install TWRP on the Galaxy S6 running 5.1.1 Lollipop.

Mind you there are a few kinks here and there, so follow this guide to every word and you shouldn’t have a problem.

    Can you post a video demonstrating this? I got the kernel to flash successfully, but after flashing the TWRP recovery, it would get stuck at the S6 logo with the red line at the top left “Recovery is not seandroid enforcing”. I had to use KIES to recover my phone
