[Q] Strange Problem Flashin KDZ - LG Optimus G (International)

I have an LG F180K and I have unlocked bootloader and installed cwm recovery using FreeGee & i used mako unlock. For some reason I need to flash stock KDZ. But every time I go into download mode and try to flash the KDZ the phone restarts in bootloader mode (I mean when I had to select recovery or power off that menu) after a while. The flashing process can not continue because the phone is not in download mode any more. Please help me

When that happens do not close KDZ_FW_UPD. Turn off phone and put it in download mode again... and it will start flashing kdz.
i don't remember maybe you have to unplug usb from computer when you are in dl mode again... but try first method

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

Thanks but i've already downloaded that .kdz sevral times and it still doesn't work. I have access now to download mode and recovery mode. Just need some kind of ROM that will install on my LG. I had already 2 versions but everytime in recovery install was stopped and i saw image of broken droid :<

[Q] Messed up my E975... need help... :(

Hello all, on a stock E975 I installed freegee and then cwm, unlocked the bootloader and installed fastboot (i think, there's the start menu if I hold vol+ and power).
The phone shows 'google' and an open lock at the boot also.
Now, I messed up the OS of the phone and t the moment it 'only' boots to cyanogenmod 10.2.0, wifi and Bluetooth aren't working and IMEI reports all zeroes if without SIM, 'unknown' if SIM is inserted.
I know his is a big trouble since I haven't freegee backup anymore but I'd like for the moment to return to stock firmware. Onestep at a time.
So, I need help in how to install stock firmware since the various methods I've tryed so far aren't working.
I got the right E97510H_00.kdz file downloaded ith the Original LG firmware program but I am unable to flash it anymore using KDZ_FW_UPD.exe: I start with phone in upload mode but the program reboots the phone, fastboot menu comes up and firmware update cannot continue anymore and exits with an error.
What should I do to let KDZ_FW_UPD continue with updating firmware?
SOLVED!
Just made a 910k type cable, connected phone to PC and set lg updater to Emergency mode.
Stock firmware restored perfectly and IMEI is working again too.
also...
when the phone reboots to fastboot while trying to flash kdz, power off phone, dont close/exit kdz updater, disconnect usb cable, switch to download mode again and the flashing should finish. i always had success with this one. hth!

Disconnect phone and pressing for 12 seconds power button (don't close KDZ Firmware updater or R&D Support Tool), well when your LG Optimus G is total shutdown, put it again on download mode and connect to PC, flash process continue without problems.

[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.
Use cwm or any other recovery backup to restore

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 .

I've Tried, tried through LGUP and it showed me unknown model so I couldn't do it with LGUP. Also tried with lg flash tool and had a disconnection with server and couldn't flash...
When I try to flash the 6.0 kdz it has the same message but after a while I press Retry and it flashes the 6.0 kdz.. after flashing the phone will turn on and work for a few minutes (not 100% ok) and then shut down again, with the ability to turn back on after removing and replacing the battery (and the all shut down process continues).

Think you flashed a KDZ that is not for your model.
I thought so too for a while, but i Double checked and I'm flashing the kdz for D855 European Offical (which is what I have)..

Thanks for everything, for now it works. I flashed all over again the marshmallow version and this time it didn't even turned off yet.
so after a day of using the phone is shutting down again and won't boot into recovery (since I have stock recovery) and won't boot into the android system - can only get into download mode. what should I do?
Maybe you have a battery problem, try another battery.

that's what I've been through: kernel crash due to connecting the battery when the phone was connected to pc with usb cable. than after many times I tried flashing through download mode with lg flashtool it worked for almost half a day and then suddenly it crashed again (when I tried to install spotify on my phone). all through the process when I tried to flash a stock rom with LGUP it wasn't possible because of unknown model error. right now I re-flashed the marshmallow version (because for some reason that's the only stock rom which I can flash and it would work from time to time), and it crashes all the time after a few seconds of using it and getting back to boot loop. Mods I can enter: Only download mode (no recovery and crashes when try to turn it on)... Any ideas what my next move should be?
