[Q] Change LG Optimus L7 p705g v10e Software Version

I've recently been searching for a root for the LG Optimus L7 p705g v10e for a friend of mine and learned that there is no root available for this software version (v10e). I am unable to update his software version in order to root.

Does anyone know a way to change this software version so that I will be able to root this phone?

Thanks in advance
