I searched via google and found nothing on the nitro, so searched for the LG Optimus LTE. The method i found for that phone did nothing, it just gave me errors when trying. So, i thought i would try SuperOneClick. Im used to Samsung devices which are super easy to root, so im not sure if what i encountered in Super were normal or not.
I allowed super to force an install drivers for the device and then unplugged the phone and plugged it back in. The root started and errored out after trying a zerg rush. I didnt unplug the phone or anything, i just immediately tried again. This time it said it was successful but when attempting to restart ADB, the software hung. I restarted, and also unplugged then replugged in the phone. Clicked root one more time, and it worked.
Anyways, im simply posting because like many others, i search these forums before going anywhere else, and im hoping that my experience will help someone else. I dont know if it was a fluke that i had to try multiple times or it was just something with my configuration. I hope this helps someone, just be persistent and it should work.
