I have a lg optimus g pro f240 running on android os version 4.4.2. I recently rooted the phone using the software in This thread

I have installed SuperSu though each time I try and open it, it tells me The SU binary needs to be updated. Continue ?

It prompts me to use CWM, which I have installed, though each time I try and use it SuperSu does nothing and just opens the app.

Each time I click continue, after 30 seconds I get the error message:

Installation failed!

Please reboot and try again.

I have tried rebooting, though nothing solves the problem.

If the rooting software linked above did not work, how can I test and see if that is true?

Is there any way to update the binary manually(I have tried sideloading SuperSu but an error in tmp/Update happens)

What options are there that could fix this problem?
