Softbricked bootlooped unflashable G2 - G2 Q&A, Help & Troubleshooting

Greetings,
My Puerto Rico (Claro) D801 (which is actually a D803) is softbricked after successful rooting but failed KitKat firmware update. I'm used to rooting phones, but the G2 seems to have a few particularly broken elements. I essentially bricked my G2 because it identifies as D801 in software/hardware, but isn't actually compatible with D801 firmware. Major issue, which apparently loads of other people on XDA are having.
Summary:
Can't restore firmware from the phone (stuck in fastboot)
Can't restore from LGMobile Update application (Windows sees the phone on USB but application doesn't)
Can't flash either D801 or D803 TOT using LGFlashTool because of the identification issue.
I can get into Download mode.
I'm desperately looking for help in fixing this. Can supply more info on what I've already tried.
If you're having similar issues, I'm @michellzappa on Twitter. I just sent a public reply to @lguSAMobile containing a Google Documents link where I outline all the issues I'm having.
Thanks.

[Q] [t-mobile d801 soft bricked can't use LG tool

I can get into download mode, but have a secure boot error and cant use ADB or fastboot. I've been reading every thread I can find.
I tried the LG tool, it never downloads the firmware, just hangs at 12%. Tried different drivers etc. Let it run overnight just in case it was a slow download - nada.
Tried the LG tool by entering the imei number first, but the tool reports a low battery and won't load the firmware. Phone is fully charged, i assume that battery level reporting is not working correctly.
Tried to load the kdz with the R&D tool, it errors out at 49%.
Tried to do the offline process with shttp from the unbrick any phone thread. It uses an older version of the LG tool and won't recognize that the phone is plugged in. If i install the newer tool that sees the phone, the process crashes the tool.
it all started when i tried to flash twrp and used the one for a different model g2. Dumb, I know. this is my first time soft-bricking a device.
Can anyone please point me in another direction?
UPDATE: phone was reporting that it was an 802. Downloaded and flashed an 802 kdz file and the phone booted! First time it was able to get past 49%. Nothing really works on the phone, but now i'm able to use the LG Mobile support tool to flash the correct firmware. The program is downloading the sofware now.
When you say LG tool I'm assuming you're talking about the official program you can download from their site?
I have the Verizon G2 and promptly erased everything on it the first night I got it.. Don't flash / wipe files at 4 AM when you've been up all day and night.
Anyway this thread http://forum.xda-developers.com/showthread.php?t=2432476 really saved my rear. Maybe the T-Mobile version will work to get yours back to stock.

works at the start and hangs at 49%. There is one bit that needs to be switched and this would work.
okay, looks like the phone is reporting that it is a d802 from my first f'd up flash. I think this may be causing the problems with flashing the 801 kdz.
Can i flash an 802 kdz onto an 801? then possibly later go back to 801?

LG support tool said I have the latest version when restoring my D802T

Dear All,
I am trying to restore my bricked G2, but when I got to LG mobile support tool and select the language, it does NOT flash the KK kdz I downloaded, instead told me "Your device has the lastest software available from the LG mobile support tool. Please visit LG support website for more info..."
WHY???
FYI:
D802T Australia unlocked version, official 4.4.2 then rooted and installed Autorac which doesn't support D802T and stuck my phone at bootloop for good. Already downloaded the KK kdz. file and tools and followed this post"http://forum.xda-developers.com/showthread.php?t=2432476"

Found any solution to this? Have the same problem, it says i have the latest software even though the software it is showing on my phone (which my phone doesnt really have) is older than the KDZ that I am trying to flash. If I force it to upgrade, it starts but gives an error at 37% every time.

Use the LG Flash Tool instead.

[Q] LG G2 T-Mobile Recovery gone wrong

Hello and thanks, for any help given in advance. I am using LG Flashtools 1.8.1 to get my phone back to 4.2.2. I have no access to the recovery and my phone boots into a ATT rom for about 30 secs then crashes and starts over. When I try to flash the D801 BIN and DLL I get an error saying that the SWV and the SWOV are not the same. They read as the D800 (the ATT variant). Any other LG support tool doesnt get a response from my device. When the operation fails my phone reads:
USER S0.0 AS0.0 B100 UHS
S U LG-D800 04.2.2 Hrev_10
D80010o
UNROOTED
I think in order to fix this I must bypass some sort of secuirty check. Unfortunaley I do not know how to do such a think.
And again thanks for any and all help.

G2 D802 touch screen weirdness and baseband issues

Hi all,
A quick peek of touchscreen issues attached:
http://youtu.be/Hhuiv1SdsDQ
I enabled show touch options in usb debugging and took this video. Every touch on the screen is registering atleast two and mostly three touches as you can see in the vid. Any way to resolve it? I have tried to downgrade OS to 4.2 using LG Flash tool, and that doesn't work.
How do I fix this? Is it a hardware issue?
Baseband problem:
When I downgrade the phone to a D802 v10B or 10A, I lose baseband. Currently has India KitKat D802T20A_00.KDZ installed and baseband is present. Even downgrading to D802T10A_00.kdz loses baseband. Any thoughts why this is happening?
Try to go to hiddenmenu by dialing the number and then find update touch or something like that and or check your screen for dirt and clean it
fix found ?
I ran an update on my g2 from lg, and ended up with the same issue. Have you found a fix?
Same issue on my G2 (see my thread) but yesterday I gave up and send it to LG to fix it.
I tried nearly everyting I guess but nothing did help. Also the way into the hidden menu was without any result.
So I wish you good luck.
Me too!
I have the same issue. (VS980) It's impossible to use the phone while this is happening.
Now that I think about it, I didn't have any issues with this until after I installed the latest OTA
Anyone have any ideas to fix this??
Update
Finding out stock firmware and calling lg tech in the morning. Will update if I make any progress.
Reinstalled "out of the box" original rom ver. VS980-24A (.kdz) using LG Flash Tool. Problem gone - worked fine for several hours. Phone asked to install Verizon update VS980-26A, problem has returned. Called tech support, they couldn't understand the issue and decided my device was broken. They are sending me a replacement under LG warranty.
I used this for returning to "out of the box":
