Install:
1. Install the LG drivers downloaded above.

2. Install LGFlashTools v1.6 (but don't run it)

3. Extract the TOT and .DLL file from the ZIP

Drivers initialization:
1. Put the phone into download mode. (Turn off device PRESS VOL UP while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)

2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).

3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.
4. Unplug your phone! Important step.

LGFlashTools:
To get this tool to work, you'll need to do a few tricks.

1. Set the computer's date to some time in July 2012 or before.

2. Disconnect the internet

3. Find a serial number or register key from somewhere on the web (a google search for lgflashtools serial will yield some results). Can't help you here and please don't share any keys in this thread or get us in trouble.

4. Execute the LGFlashTools. It should ask you for a key, put it in. Now you should see a dialog where you can load the DLL file and the TOT files that you extracted earlier. Put them both in here. Click ok

Flashing:
5. There is a yellow arrow on the top left. Click on it to initialize the process. Once done, it should say "ready/finished" or whatever.

6. Put the phone in download mode again, and plug it into the USB port. LG FLash Tools should start flashing it automatically. When it's done, it'll automatically reboot into your stock AT&T rom and all of your data and internal sdcard files will be gone.

saw some posts that have already been answered in the thread in the general section, so for those wondering:

1 - There is currently NO NATIVE ROOT for the 4.4.2 d80020c firmware. It has been patched and another exploit has not been found yet. So don't ask. You'll see threads when it is found and released. Promise.
- You can root by rooting a previous 10x firmware, and then updating to 20c, but you *must* have stock recovery.

2 - There is currently NO WAY to have custom recovery on 4.4.2 d80020c
- You put 20c on, you stick with 20c. no way to flash other ROMs. Loki was patched.
- We do have a workaround, but we need the kernel source (loki'd boot.img from 20c using 10o aboot). So until LGE posts their source or someone more versed in this can find an exploit for the
bootloader/kernel/aboot , we're stuck.

3 - I have been using the rpm, tz, and modem from 20c with 10o partition images with no negative effects. Although I don't recommend trying to flash the rpm and
tz images unless you know what you're doing / risking.

Enjoy the Fast Download
