Default LG Motion wont turn on stuck on black screen

I just rooted my lg motion and went fine, then i rebooted the phone after setting phone up and its stuck on a black screen. i can't access download mode or hard reset mode. Its acting as if the battery is dead. I did make sure through out the process the battery was atleast 75% so its not a power issue. When i hook it up to computer i get the lil beep from pc acknowleging a device but nothing on lg motion screen and the lg support tool and other root scripts say they can't find device. HELP Please!

Sounds like you need to reflash and start all over. Check out the unbrick guide.

http://androidforums.com/motion-4g-all-things-root/610609-guide-unbrick-lg-motion-unroot-getting-1-5ghz-kdz.html

pull the battery for a few seconds then hold vol up/down while holding power button to enter Download Mode

better yet check out this link as well

What's so special about the dongle? Is it just a usb cable with a resistor between two pins?

A USB dongle is something that looks like a USB flash drive, but the only reason for it is for some kind of license key that the program uses to verify that you bought the program. It must be inserted for the program to work.
