I have tried to do that ( 3 times ) Using Triangle away :
1- I've got into Triangle away Hit Reset flash counter in Triangle away.
2- after restarting my device I got into SuperSU > Settings > Full Unroot.
3- Restarted my device , now there is no Root access.
but when I get into Odin mode ( Binary Counter : Custom (Yes : 3) )
is there any way to reset Binary Counter ?
Thank you .
