[Q] NEED HELP: Droid Razr HD rooting: KitKat 4.4.2, 182.46.15.XT926 topic

Hey guys. I recently rooted my dad's old Droid 2 and installed CM9 on it. I decided now to try rooting my phone so I can use the microSD card slot as extra RAM.

I have looked around, and I cannot seem to find any way to root the Droid Razr HD. From the specs listed in the title, is there any known way to root this device?

Thanks!
