Help me unbrick Optimus G

Hi,
Yesterday i tried to get recovery mode on my phone to install new version of android (korean version of Optimus G). So i tried by reading topic: http://forum.xda-developers.com/showthread.php?t=2249500
After i had 85% in LGNPST i disconnected usb cable from phone and my phone bricked. At first i had bootloop and i could only get into recovery mode. Now i have only download mode... I tried to unbrick following that topic: http://forum.xda-developers.com/showthread.php?t=2010624
So in that app Original LG Software i type Model of phone: F180K (like it is on box of my phone) and my IMEI number. After download a almost 1,2GB file with .kdz i set my phone for download mode and any program cant unpack it. Always ERROR -.- http://img6.imageshack.us/img6/2136/beztytuukvn.jpg
I tried to unpack it with LG-P970 ROM COVERTER 2.1 and R&D Test Tool. Nothing works! I have Windows Enabler 1.1v and its ON.
Is there any other way to fix my phone? Help me please.
EDIT:
Can be closed. @autoprime from #lg-optimus-g irc helped me thx :*
Download:
- LGE975AT-00-V10b-EUR-XX-FEB-13-2013_0.tot from http://downloads.codefi.re/shelnutt2/optimusg/e975
- LGNPST
Solve:
-Turn your LG into download mode
-Change LGE975AT-00-V10b-EUR-XX-FEB-13-2013_0.tot to LGE975AT-00-V10b-EUR-XX-FEB-13-2013_0.bin
- Use LGNPST to install that file on your LG
Phone should turn off on 67% and if you will have bootloop you should press Vol- and Power to factory reset.

I think the KDZ is corrupt. Try downloading another. There is a thread with stock roms in dev section i think. After you flash the KDZ you might run into a bootloop. If you do, turn off your phone and press vol down and power you should get the choice to do hard reset. BEWARE! This will ERASE EVERYTHING ON YOUR SDCARD!
Good luck /Robert

G3 stucks in Download Mode

Hello Community,
Yesterday my G3 stucked in a Bootloop without changing anything. Than I wanted to repair it with the LG PC Suite. This failed with the message "Assert" multiple times. Now it stucks in the download mode. Can I repair it? More important are the files on the G3. Is there a way to get them?

Try this:
1) Remove battery
2) Hold down the power button for 30 seconds with the battery out
3) re-insert battery
4) Try turning it on again.
If that doesn't work, do a hard reset. You can find multiple posts on how to do it. Hope this helped!

Maybe I can help somebody with the same problem. I solved the problem with the following steps:
I setted up a new Windows 7 x64 PC. It must be Windows 7!!! No Windows 8 or other shiny things.
Installed the driver
Flashed a compleltely new firmware (.tot) over the old (!) FlashTool.

Hi guys. First, sorry my poor english. I'm Brazilian.
I make a firmware upgrade from LG PC Suite, 4.4 KK to 5.0 L. Problem is, the upgrade failed, and now my LG G3 are stuck in download mode. I try make this upgrade from LG Flash Tool but the problem persists, 65% appears in the screen of LG G3 a message "ASSERT" and reboot to download mode screen. Help, please?

Although I have never come across this, using this site to download the right KDZ and using this thread to flash that KDZ may solve your problems. There is no harm done in trying this and you can be sure that it is the right file.

LG G3 Boot problems after download mode
Hello!
Sorry revive the topic but it was the only one who found a similar problem, after searching lot on google.
I have a LG G3 D855P. Yesterday he went out and restarted many times, but worked for a short time.
I can use the BoardDiag, but when I restore the D855P20C_00.kdz .kdz, to reach 36%, the cell phone goes off and does not return. I need to take the battery cable, so that it returns to the download screen, but still, to get 36% he goes again. Have made sure that the .kdz file works properly.
I followed the tutorial presented in this video.

[Q] Stuck at fast boot LG G3 F400L

Hi all,
Long time user first time posting a thread [sorry couldn't help myself]
Anyway I have a LG G3 F400L and I accidentally installed D855 rom on to it [AndroidNow_HD_8.0_Lollipop].
I have tried flash tool to flash the correct firmware but to no effect it now detects it as D855, so I cant install the F400L firmware using the F400L dll. I am installing an older firmware i.s 10e I have also tried 20f for F400L but the new flash tool doesn't recognize my phone, I have tried different USB ports and a different PC with Windows 7 32bit still nothing.
I am using Windows 8.1 64bit.
Regards and thank you for the help.

Anyone, please help.

Thank you for the response. I do not have access to recovery, only download mode works.
Update: I have tried using a general Dll to flash TOT file via flashtool but it doesn't let me error CrossDl [D855] to [F400L].

I had this and I set for 4 hours figuring out how to fix it. ( I had not accsess to the download mode first only to hard reset which didn't work and the "Fastboot mode started")
If you have access to the Download mode that's perfect, Follow this Tut:http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
Please make sure you download the correct TOT file for your phone.

Thank you that did work sort of, I was doing the same thing but someone in the comments referred to a modded DLL for the flash which did the job to some extent at least.
Its back to stock but stuck at McAfee activation, requires a pin which I do not have nor have ever created one, and now a Kill switch has been engaged and no more download mode. Out of the fire into the frying pan is what I feel like right now 100hours and 33mins without my G3, but who is counting.

That's sucks where did the McAfee activation came from??
Have you tried a hard reset ? or can you access the fastboot mode again ?

Nothing, no download mode or recovery. Boots up asks for language selection and then McAfee pops up of PIN. I am talking to McAfee support hopefully they can help.

Goodluck with that!

Thank you all.
Finally fixed. Just needed to be quick, the McAfee app gives you about 30 secs to do your thing then it pops up for pin. I opened up the McAfee app -> setting and changed the pin .

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.

i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.

i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!

Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english

Best regards,

Can your phone connected to PC when it boot , if it can , Then try to flash the kdz , the phone will get into download mold .
I flash kdz like this way , maybe this will work for U too .

Your PC can't detect your phone in download mode , but it can detect it when your phone boot into current system , isn't it .
Then you don't need get into download mode , you can flash kdz when the phone connect to your PC successfully (the phone is running current system ) , of course you should install all of the drivers before you do this .
can you get you phone into download mode like this: press volume minus , then connect you phone to PC , if it can , I think it can install the driver successfully.
