Root su binary update failed

[nabinsundar]

When google play showed me that there is an update for superuser. So I update this, after than an annoying message came that su binary is out dated... So I also update that, but it stuck in middle flashing that "copying su to /system". So I closed it and uninstall the update of superuser. I didn't flashed any Rom in my android. So plz hepl me fix this...

Have you done a Nandroid backup that you can restore?

Try downloading a new version of Superuser on PC & then flash it again.
