In case you were wondering whether the best custom recovery in the land would come to the Samsung Galaxy S6 and S6 Edge, wonder no more. TeamWin has released TWRP (TeamWin Recovery Project) for the Samsung Galaxy S6.
There are install methods that support both rooted (download this app from Google Play for a quick and easy install) and unrooted (flash a file through Odin) devices so if a custom recovery is what you desire there should be little in your way to get it.
TeamWin has download links and installation instructions right here, so be sure to check it out if you’re interested. Remember to read everything thoroughly, only use TeamWin’s recommended download links, and know that anything that happens as a result is no one’s fault but your own. Knowing all that, have at it!
