SuperSu update binary error
Heyy tristo
          Its not a fix solution but for try you can download su binary zip file from google 2.76 version and after download move it to sd card from downloaded folder after shut down the phone and come in reboot in recovery mode normal power off and volume up and down key press one time to reboot but setting may be change for your phone so check on google before rebooting after when its done choose recovery mode use volume up key to select then select install zip from sd card use volume down key and press power button then select zip file from sd card at bottom and press power button and then click yes to flashing after done flashing press go to go back and from options reboot the system.after reboot go in supersu error should be going on if not click on continue and normal mode its showing installing binary after some time it will show installation sucess and reboot so reboot now and then open supersu its time error will go surely if not continue process done again and this time don't reboot click on ok and close supersu and open again problem may be solve
