Help LG phone won't root!

[Lannyguy]

my LG optimus l90 d41510e phone won't root on king root! I tried towelroot as well, but it told me my device isn't compatible. The step it stops on is "checking USB connection", but I checked the connection and there was no problem? Can anyone help?

Hiya!
Is that the T-mobile variant?
If so, perhaps this thread may be of some help?
