[G2 Q&A, Help & Troubleshooting] ReallyRick:
Hello. I have spent 3 hours trying to find if my phone is able to be saved after something I did last night.

Here is what happened:

I read online that KitKat was available for T-Mobile LG G2 D801 Black.

On my (rooted) phone I downloaded a 1.5G file called D80120A_00.kdz

When I clicked to open the file SuperUser popped up asking for permission.

3 options appeared, (sorry I cannot remember what they were called) and I clicked install (I think)

My phone rebooted and I feel asleep.

Now my phone is stuck in what I believe to be Fastboot mode and the following is displayed on the phone screen

Unplugged from computer:

fastboot mode started

udc_start()

Plugged in via USB cable to computer:

fastboot mode started

udc_start()

-reset-

-portcharge-

fastboot: processing commands

And that's it. It never goes further than either of these two options.

Also, when running the LG Mobile Support Tool is says "Waiting for Connection" and will not recognize my phone as being plugged in.

I tried using UpTestEX to flash the stock version of my TMobile. It says there is no USB connection and shows me this information in the box below:
