for Those who just Recently jumped to <b>Flyme 6 Stable..</b>
if You're Gonna Root ur Phone & Decided to Use <i>SuperSU..</i>
Don't install the Latest Version (<u>SuperSU 2.82</u>) yet.. cos if U do, it will just say "The Root is Occupied".
instead, install a bit Older Version of it (i Used 2.79).
then the Process will Proceed..
& after ur Phone ReBooted,
You Can then Update to the Latest Version of SuperSU,'-)
[:This is all B.O.M.O.E on My M3e Flyme 6.1.0.0g;]
Hope this Helps
