How to completely unroot phone and fix "unable to authenticate" on pogo versions 0.37.0 and above Download SuperSu from the google play store, https://play.google.com/store/apps/details?id=eu.chainfire.supersu&hl=en_GB After installing SuperSu open it, click on the settings tab and press Full Unroot and allow the process to finish. If you had xposed framework on your phone you will need to ensure that all data from xposed is removed, or Pokemon go will be "unable to authenticate" To remove the xposed data go here http://forum.xda-developers.com/xposed/xposed-installer-versions-changelog-t2714053 and download "Xposed-Disabler-Recovery.zip" Download it! I then rebooted my phone into recovery and flashed "Xposed-Disabler-Recovery.zip" After the phone restarted I can now run 0.39.0
