These are the guidelines to install a custom recovery on the Samsung Galaxy Alpha smartphone with the SM-G850A model number. The aforesaid model number is the American model that came out for T-Mobile and AT&T subscribers. There is no traditional CF-Auto-Root tool by Chainfire available for the T-Mobile and AT&T option of this device so we are getting root access with the SuperSU and flashing it from within your new recovery.
