after update my supersu says there is no su binary installed and supersu cannot install it.
How do i solve it

Finally got my root back.

for whoever can read mandarin, you can check on this link

The steps include install a new recovery for your R3 which is in mandarin.

So I don't recommend to use it if you can't read mandarin
