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?
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.
Hello,
today I went to downgrade my L7 from Carbon ROM to V20A with CWM/ROOT by Homero using KDZ and when phone restarted after upgrade it got stuck at LG logo, so I tried flashing multiple times but it didn't succeed.
I couldn't even access the CWM, I tried almost all unbricking solutions.
Now I tried even with official LG Mobile Support Tool which updated firmware to V20D and it won't boot up.
a) Is there a way I can back my phone to get it working myself?
b) How much will the service cost as my warranty expired?
Thanks a lot!
Anybody?
Please, I really need to fix this device.
EDIT: Solved.
reinstall rom, maybe this can help u
Hello Experts,
===========================================================================================================
Update - 08/Jan/2015
I tear off my set & found several things
1. My back cover, settings > Software info & booklets shows it D802, while internal plastic is labeled as D800 & Motherboard is D801 T-Mobile. Look like some company is selling T-Mobile as D802.
I read it on this forum that if flash D802 rom on T-Mobile D801, then need to reload Kernels of D801 too after flashing D802 rom. I tried flashing D801 kernel in recovery mod but it gives error "E invalid certificates" or something like this, I also tried flashing D801 stock rom, but LG Flash Tools 2014 gives error at 2% (Phone disconnection & sometime "Connection to server failed"), however, LG Flash Tools flash D802 without any issue.
Now, can someone tell me how to flash D801 kernels after flashing D802 rom? Or how can I flash stock D801 rom?
===========================================================================================================
I am facing quite odd problems. please help me.
I have LG G2 D802. My software version was d80220b while when I attached my mobile with pc, pc suite notify me that d80220c is available. I upgraded. But after upgrading, touch is totally out of work. Say like below, I tap "7" & it goes to 2, 3 etc. I select say first option, it selects 4th option.
Also, one more thing, my mobile is 32gb variant, while now it's showing only 10.7gb.
Three Problems total
1. Touch totally disturbed
2. Storage reduced from 32gb to 10.75gb
3. Service Disabled (No sim is working :'(
I think it's due to some rom issue, can you please guide me or send me link for the correct ROM for my mobile?

Nothing was loud thinking but cant help you here anymore sorry told you everything i know
For some reason I can't post when I use the model number listed in the title and the Canada variant model name. Says the post is "flagged". So that's why I'm not using the model numbers.
Hi. So last week I got a new V20....and I bricked it...within 3 hours. I'm hoping someone can help me out. So, here's what happened. I'm sure this subject has been posted 1000 times, but nothing I've read is exactly like my situation.
I bought a AT&T Model. I didn't realize how complex it was to root it. Was very easy on my D855. First I made a backup of all partitions with LGUP. Which is useless, since it's, not a kdz. I tried to unlock the bootloader with Dirtysanta. I got the static. I reflashed it with the stock Canada variant kdz. It booted just fine, but had no service. Dirtysanta also resulted in static with Canada variant rom. Reflashed Canada variant again. This time using one of the LG tools I tried merging the AT&T Model modem into a kdz file, hoping it would get a cell signal again. This failed spectacularly, because LGUP said it wasn't a valid kdz. (I'm guessing kdzs are signed and LGUP verifies them? Don't know. This stuff is clearly new to me.) Anyway, at this point I tried the dirtysanta method one more time. Got stuck with a bootloop about "corrupt device" and the red triangle. Finally managed to get download mode to work again. Flashed it with stock US996 v10f. Now it's impossible to go back to Canada variant kdz, and there is still no AT&T Model kdz. So it looks like my once AT&T Model is now stuck as a US996. Which, I guess is ok with me. Mainly I just wanted to get rid of the AT&T crapware. But, of course the FM Radio doesn't work now. Also, dirtysanta also gives static with US996 rom. Most people said if you turn the screen off and back on, the static goes away. But for me, the buttons don't. Phone doesn't show up in ADB, Windows explorer or device manager. But it's fully booting, because through the static I can see the "Welcome" screen. Now, if I'm understanding this right, the FM Radio doesn't work in the US996 version because of the kernel. And boot partiton = kernel? So using LGUP with PARTITON DL, I flashed just the boot partiton from the Canada variant kdz. Got to the second "LG" screen and doesn't boot past that. So, I flashed the correct boot partition back and it once again booted. So, fianlly to what I'm asking. Is there anyway to get:
1. TWRP recovery
2. Rooted US996 rom
3. The static to go away...and go away permanently
4. FM Radio working (there was talk about custom kernel?, but haven't gotten that far since I can't get the static to stop)
5. Red triangle error to go away
Last issue isn't that big of a deal, but just wondering if anyone has a fix for this yet. Help would greatly be appreciated. Thanks.

Static after engineering boot is fine. It boots up after a minute of wait on static screen. Also that triangle mark screen is fine too, wait for a minute which u didn't.
You should have followed brian's guide to root an H910.....
[ROOT] HOWTO: AT&T H910 up to v10v (FULLY TESTED)
https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500
Even I was able to root using this method on my Puerto Rican v20 H910PR
Thank you. I finally realized what I was doing wrong. I was skipping the step on installing H915 kdz FIRST. Guess it helps to actually follow all the instructions! Anyway, I got it working. I was even able to completely get rid of static boot with MegaRom & the mk2000 kernel. FM Radio works, too!
