What exactly did you do in G3TWB that lead you to here???
To fix this... Use the appropriate TOT file to restore back to stock.

Stock unrooted and it did that? Did she drop it or get water in the phone somehow? What error did it give (if any) in the flashtools? At what part of the booting process does it stop?

Hello, I have the same problem of bootloop in CWM.
It begins after performing a factory reset from Android settings.
I have a G PRO F240L rooted whit this method : http://www.technostall.com/lg-optimus-g-pro-f240-root-and-install-custom-recovery-image/
I tried to follow this method http://forum.xda-developers.com/showthread.php?t=2420219 but it fails because of error "insufficent battery"... while my battery is fully loaded..
Thank you for your help

[Q] Bootloop, and factory reset is stuck [SOLVED]

My device is rooted with towelroot, I installed supersu afterwards...
before bootloop I installed fontexplorer, and installed few fonts, it asked me to reboot, i rebooted, and now it just bootloop's all the time, LG animation and vibration, I can't get into fastmode, tried all kinds of button combinations..
When I try to factory reset, after pressing yes it shows erasing, and then it's stuck on boot logo, not animation..
Download mode is stuck also, just shows 0% but at least then pc's device manager shows com device found
How to fix this ?
All this happened after I rebooted my phone, before rebooting I installed few fonts with Font Installer ★ Root ★(com.jrummy.font.installer) app
THIS guide will help, you've softbricked, only in this guide you will of course need the dll and tot files for your phone and not Sprint. As long as phone comes on,computer recognizes it, and, it goes into dl mode, you should be good.

That stinks huh?!
I've been using iFont and Fontster from the Play Store without any issues for future reference.

G3s to me are finicky about changing or modifying. I modified one build prop setting, rebooted, same thing as op, mine wasn't bootlooping tho, but stuck on the big red 2 screen. Flashtool is your only friend at this point.

Wow, I can't believe I fixed it, I thought it's impossible
I just went into download mode and used LG Flash Tool 2014 to flash to stock firmware..

If phone is not sprint, then KDZ method works too?

I think I read back when I was unbricking that .KDZ files have to be converted to .tot, to use with this version of Flashtool.
Quick Question
Hey guys,
I am a bit of a rookie with rooting and i have an LG G3 for tmobile. I rooted my phone and had TWRP installed and accidentally attempted to install a software update and it soft bricked my phone. Here is my problem-all of the solutions i am finding for this issue require a PC, and I, unfortunately, am only running on mac software. I have no way to get lg flash on my mac and to make it comparable with my phone. Is there ANYONE who can help me? I am at my wits end and CANNOT believe I was so stupid as not to make a backup flash but I, as per usual, did not think about it at the time. If anyone could help me, I will be forever in your debt.

I believe you can run virtual Windows on a Mac, not sure if it works with Flashtool though.

Why so serious, use bootcamp and install windows 7 directly, and come into my debt.

Unable to boot my rooted LG G3 S (beat), stuck at lg logo.
hello everyone. I recently rooted my lg g3 s (beat) D722K. After a few weeks I was trying to install apps as system apps using ES file explorer for which I had to copy the desired apk in the system/apps directory and restart the phone. it worked for a few apps (which I successfully made sys. apps) but not for a majority of apps . Everything was fine until now . After that I wanted to normally install an apk but the phone was unable to install it showing ' application not installed' . Then I tried to install other apps but got the same result . I decided to reboot my phone but it got stuck on lg logo and won't boot .
I tried to factory reset it using hardware keys but after wiping all the phone data it again got stuck on the same sucking LG logo .
I also tried to update firmware by connecting it to windows(8.1) pc in download mode which didn't work either. The firmware download got stuck at 0% everytime I tried.
please help me in getting out of this issue . I will heartily appreciate any help regarding this issue.
thanks.. in advance.

LG G3 screen goes blank when booting or updating Android

Hi, I have weird issue with LG G3 D855. The phone works fine when Android is booted but the screen is blank at start up (no lg logo), when in recovery or download mode and while the Android is updating.
I bought this phone like that. I installed the LG G3 Stock Factory Firmware D855 European (LGD855AT-00-V10e-EUR-XX-JUL-08-2014-16G+0.tot and LGG3/D855/LGD855_20140526_LGFLASHv160.dll) using LGFlashTool but it still has this problem. Currently updated to Android 5.0 V20u-EUR-XX
Is it possible to be a hardware problem? Are there different parts on the motherboard that control the screen when is running Android and when is running bootloader?

Did update via ota or computer?
I updated via ota. But the phone had the same problem before the update with fresh install of the stock firmware.
Did you try unbick/unroot

It sounds more like a software problem, but are you rooted? and do you have any custom ROM or recovery previously intalled?

Phone is currently not rooted. I don't know the history of the phone I bought it second hand with this fault It came reset to factory settings.
The only thing I installed is the stock firmware (LGD855AT-00-V10e-EUR-XX-JUL-08-2014-16G+0.tot) because I thought it will fix the the issue.

I tried the tot method from that topic and still got the problem.
I assume there is another OS that handles everything before the android is booted for example Download Mode or Recovery Mode and that's exactly when the screen is blank. Are KDZ and TOT methods flash that as well or I have to use something else?

The link I gave to you is flashing everything back to stock (recovery, download mode, os, modem, etc..) so its kinda wierd that it don't work, you should try again a few time.

Well if the phone works fine well i think you should just leave it like that, but it´s really weird that the screen is like that on the boot anyway, you could try to root it and apply a boot animation by yourself to see if it fix the error but the flash method should had solve the issue; you can try RomToolBox from the playstore or any other root app that changes your boot animation or look for a tutorial, maybe just maybe the boot animation is not getting flashed for some reason.

Stuck on LG logo

I've had my G4 for about 11 months and one day while watching a video froze and got stuck on the LG logo. It's got no warranty and I have tried flashing de kdz using LGUP. Also tried LG Bridge which didn't work. Both times when I flashed the rom the process would reach 100% and then reboot the phone, after that It would go back to being stuck on the logo.
I don't know what else to try, or if it's definitely dead?
it seems to be the boot loop hardware problem.

Full unroot got me stuck

Hello, I wanted to unroot my phone from SuperSU, using the Fully unroot thingy that it has. After letting it be for awhile i realized it was just only at the bootup screen where the LG logo is and blue light was slowly blinking. Now I've tried LG flash tool to get me back to factory settings and I've tried different .kdz files, none of them seems to work. Furthest I got: I saw the firmware's name on my phone screen for a few seconds and then it dissappeared. Always LG Flash Tool fails after 9% and it says "Upgrade stopped due to an error." I have no idea what to do anymore with my phone. Any help is appreciated! Computer only recognises my phone when it's in firmware update mode.
Use LG UP...
