Pretty sure anti-rollback prevents that and without anything to recover if it stops halfway through I personally wouldn't try it.

Just got the phone today and successfully rooted it and I wanted to see what this xposed framework stuff was about I installed the experimental version (tbh did really read it was experimental it was on the front page so I thought it was alright) and when prompt to reboot I did, but now when rebooting I can't get passed the Lg secruity error screen I tried re-flashing back to stock using this thread http://forum.xda-developers.com/showthread.php?t=2799647 but nothing happens after I plug my G3 back in it just says ready is there any other way to fix this security error?
edit:found out that my model number is actually the f400s (sorry i'm a phone noob) for anyone else out there trying to find your phone model it's actually behind the battery

do you have a picture of the error

Again I ended up resolving the issue myself and I do not have a picture of the error but I can describe it. When booting my lg g3 the normal big Lg logo appeared then after a bit a smaller lg logo appeared with the words "security error" under it for those looking for a solution to that problem the thread in the op is the correct action to take to resolve the issue. Note doing that wiped everything on my phone which was not a big deal for me but I had to take my phone back the the carrier to input the configuration to access 4g lte again & it unrooted my phone.
i have this same issue can you tell me how you got around it?

jerimynal wiley the error you get "secure boot error" is caused by image you are trying to boot not being bumped or not properly flashed. I assume you get this error both while trying to access recovery and OS. If that is the case you should use this guide:
http://forum.xda-developers.com/showthread.php?t=2785089&nocache=1
to flash stock firmware on your device.
But if you have a case where you are able to access your recovery (TWRP I assume) you could use one of the custom images provided here: http://forum.xda-developers.com/lg-g3/development (assuming you have D855 version) . Flash them and use them as OS.
Thanks man. I actually could get into recovery so I just flashed another kernel

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.
I was using MM on my G3 D855 for the past 1 month. It was running ok with random reboots in between.
Yesterday it went to the boot loop continuously with no reason. I tried to flash again 30B KDZ file but its the same
problem again, tried resetting from the stock recovery and installing again without any luck.
Tried most of KDZ files flashing bit stuck at 4% and stops.
Also tried using TOT file with showed error message that the model number is not same.
Now iam out of any options..pls somebody help to get rid of this boot loop.
thanks in advance.

Hi guys
LG G3 looping on boot screen every time,
I had TWRP with fulmics rom installed and one day it just shut down, i tried turning the phone on but it shows the lg booting screen and then reboot, and it goes on like that, I tried installing different roms but always the same problem, i
should mention that i tried cloudy rom and i did actually work but when booting the phone it had this problem that the wifi and bluetooth won't activate, i searched on the Web and a lot suggested that is a battery problem,
so i thought the previous rom worked well so let's change this rom,I installed a lot of roms and the boot looping problem shows up every time, so i thought **** it let's get the stock firmware,
and when resetting the phone to stock firmware it's stuck in the rebooting phase at the end, boot loop again, and now that I've lost TWRP i only have the firmware solution that is not working, this too was mentioned to be a battery problem,
and i bought a new battery and nothing have changed,
tutorials that didn't work for me : http://lgg3root.com/lg-g3-stock-factory-firmware/ http://unbrick.itcse.com/unbrick-lg-g3-stuck-on-factory-reset-2/
is there anyone can help please ?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%
Have you made sure that it is the right region......
Try to down load just tot file and try that....
