My G3 F400L was already on stock and rooted. However, i read that if you modify the build.prop ro.model to a K variant and flash the K variant firmware you will end up with the an F400K - which would be better for me frequency-wise.
After 3 attempts using the TOT and DLL method, i'd always get a failure aftter 15 secs. For the first 2 times i could reboot normally into the same OS.
But on the 3rd failed attempt, it would go as far as the LG logo then the screen would go black with the pilot light glowing on and off.
Please help! I've been looking for a kdz for the F400L but couldnt find any. i plan to flash using LGFlash Tool 2014.
Appreciate any immediate advise. Thanks!

Hi guys I'm a newbie here and this is my first time posting.
I was trying to flash stock on my LG G3 but I made a really really stupid mistake. I used the flashtool found over here at http://forum.xda-developers.com/showthread.php?t=2799647 but I had used the wrong tot file. Now my phone is stuck in download mode. I don't think my phone is hard bricked because it still boots up but only to the download mode no matter what I press. I also can't access my custom recovery now. I have tried flashing with kdz file for my phone using the LG Flash tool 2014 but on the LG Mobile Support Tool the progress bar goes up to 10/11% during the s/w update and I get an error after waiting for half an hour and the progress bar on my phone's firmware update screen only goes up by 2% at most. I can't find the tot file for my phone version to flash with so I'm stuck here. Help please?
phone version : v20g-sea-xx

hi , i have the same problem.
Did you try to flash the correct .tot file again?
Check the logs for the error which is generated from LG flash tool 2014.
May be you have cross D/L error due to wrong tot file flash.
Hello everyone. My LG G3 Cat. 6 (F460K) was boot looped. It was caused by an OTA update initiated by someone who was using my phone. Now, it's not usable. Only shows the LG logo but reboots and does that cycle while it's on. It has download mode, and I have tried flashing through LG Flash Tool 2014 with a KDZ (F460K30c) and it successfully finished. However, it's still having the same problem. I tried flashing with TOT, but I somehow get this error: i.imgur.com/aB13Jig.png (XDA won't allow me to put links)
I need your expert opinions on this case. I really need your assistance. Thank you in advance!
Hello, so basically today out of nowhere, i found my lg g3 bootlooping (Lg logo+led blinking) and nothing else, tried hard reset, but got a android on the ground with red triangle, then got to download mode and tried everything that i could find to get it working, but nothing worked.. LG flash tool with dll and tot, other tool with .kdz, but everything fails... i think it might be that im trying not the stock firmware.. I tried all europeans, international versions, with no luck. got the .kdz method getting up to 99% and then the flash tool crashed, and on the phone same bootloop. found my stock firmware by IMEI, but can't download it:
6PL/PLUS_16G(POLAN V30b LGD855
The link for me isn't working:
csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW299GH752SMAA174B8C7JP/D85530b_00_0927.kdz
I'm literally out of ideas.
i have no warrienty. :/
Hello Everyone,
i need help reviving my lg g4 and i search all the forms but no avail. I just got a G4 4 days ago only it was running lollipop and working fine i just check for the MM update in phone but there was no update so as i previously own a lg g4 with flumics rom so i decided to flash a kdz with MM update. I see my model no. as h815 so i download H81520h_00_0516.kdz and flashed it through lg flash tool 2014 it flashed without no error but after the flash i got no display in phone just blue led flashes and i hear lg boot sound and then just nothing on phone display it switched off itself. I try to go into hard reset but again no display i try to go into download mode again no display. I attached it to pc it shows LGE Mobile USB Composite Device. Although it shows in lgup tool as H815 and port no. as well.I search my model no. through IMEI i found that it is actually F500L model as i see Korean as it flashed 1st time in download mode. After some research i manage to go into download mode by removing the battery and attaching the phone to pc as it shows empty battery icon so i inserted the battery by pressing the vol up button it goes into download mode. So i try to flash the right firmware which is F500L20u_00_0504.kdz bhut lgup says it invalid kdz i try to flash it through lg flashtool2014 but it says cannot connect to server and failed with contact system administrator. Although it flashes H815_EU_10C_00.kdz and India H818N10d_00.kdz firmware's but those give no display at all i tried it with Lg Bridge as it shows update avalable F500l and it download it but failed to flash it. I try flashing korean tot file LGF500LAT-00-V11d-LGU-KR-SEP-21-2015+0.tot through lgup tool but again it said invalid tot file So friends i am stuck and looking for 5 days to find any solution So anyone can please help me i just used it for 1 day . So can anyone help me.
You have to edit a F500L kdz with a hex editor and replace every F500L to H815 or something that flashes without error
First, if it's H815, you're to flash an H815 kdz with LG up

Put into download mode and refurbish the kdz accordingly.
Hello. Long story short, I have no luck with LGUP or the LG flash tool. The phone is recognized in both tools, but on LGUP(ver 1.14) it shows up as “unknown” and on LG Flash I go as far as 2% of the flashing process and then an error occurs. All of this whilst the phone is in Download mode. Don’t know anything more about the phone, since I just bought it off of a dude. The phone is operable only in download mode, otherwise when I try to boot normally, I get stuck on the LG logo (bootloop idk). I’ve tried different KDZ and TOT roms with different DLLs but no luck. Can somebody guide me? Thanks a lot in advance.
