(I posted here because I thought this would be a more appropriate forum)
Per your request I tried to flash the CWM that you had listed here. The attempt failed. I think it flopped due to SuperSU being present and not Superuser. I have superuser on here, but it is subservient to SuperSU. Regardless, it didn't work. I am hesitant to uninstall SuperSU (I am not sure if I would retain root with just Superuser), but thus far with your CWM bat. it hasn't worked.
Hope this helps....
Edit: I took a chance and uninstalled SuperSU and it seems to be still holding root according to Rootchecker. I ran the bat. file again and I am still coming up snake eyes.
Here is the documentation.
