[Q] [HELP ROOT] Need a root (or towelroot modstrings) for LG F70 D315 topic

I have an unlocked (South Korean) LG F70 D315 device running Android KitKat 4.4.2 (Kernel Version 3.4.0+)(Software Version F370L10i), which apparently does not seem to be a very common smartphone. I have had root on pretty much every other phone before this one, and it's pretty frustrating to not be able to get it on this device. I have read multiple threads and sites about rooting this device, and they all point to towelroot. I've tried towelroot, but both the standard and temporary modstrings resulted in the 'this phone isn't currently supported by towelroot' message. I've tried messing around with modstrings from other threads I've found, but no result. I am not a developer, and have a very basic knowledge of Android development, but one thing I do know is it's a pain to go without root.

So my question, does anyone have another method of root they can recommend, or have modstrings that might actually work with this device?
