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

Help!!! My LG G Pro (F240K) stuck in the LG logo.
I follow the link below to flash the Lollipop 5.0.1 for LG G PRO F240 K into my LG G Pro(F240K). It finished the update process but now stuck in the LG logo screen. I remember my original version is 4.0.x.. I didn't have a backup of my original kdz....
I just root my device but never flash any Rom before. Is there any problem to flash 5.0.1 into it?
I tried to download a Rom F240K10r_00.kdz to flash again. But still stuck in the LG logo. I don't know what to do now.

"CSE Flash" will wipe all data in your internal storage.
I also had bootloop when downgrade to 4.4 from 5.0 with "Normal Flash", then I tried "CSE Flash" and It worked.

I have hope when the signal show. Just check the hidden code set the network show LTE. Try to WCDMA/GSM reboot the phone the issue FIX. Now my OGP fully work with Kikat and try to Flash again to Lollipop and successful my simcard fixed. Correct i am using CSE to flash and its work. I think the phone baseband installed try to stable and optimize it self first to network on my country.

Hey I have the same issue, not yet solved.
I was on F240L30C Lollipop and Want to Downgrade Because I am facing Screen Wake up issue (no issue when i was using KitKat 4.4.2).
I have downloaded the f240l20c_00.kdz firmware from pan.baidu.com , but after flashing my phone gone in to loop (Lg logo then android animation icon processing then reboots again)
I can't enter the recovery mode as well.
I have tried using CSE Flash but same loop again.

Hi All,
I received the official LG OTA MM update for my H815 (TWN) a week ago and I've just noticed that the bluetooth function now doesn't work at all. It won't even turn on and there is no MAC address associated with bluetooth in settings (It just says "unavailable"). On 5.1.1 bluetooth worked fine.
I've been trying all day to downgrade back to LP 5.1.1 using LGUP but it gives the "TOT file is invalid[1]" error with every KDZ file I have tried.
I have tried these KDZs:
Europe H81520C_00_1218.kdz
Europe OPEN H81510D.kdz
TWN H81520b_00_1218.kdz
The phone is running MM 6.0 and V20c
LGUP detects it as "H815" on COM4 when connected.
Does anyone have any ideas as to what I am doing wrong? I really need the bluetooth to work and this is soooooo frustrating.
Thanks in advance.

Flash recovery firmware using LG Bridge. That'll solve the problem.
You seem to have flashed wrong (partially incompatible) KDZ file on your device. Talking about H815 itself, there are multiple versions based upon provider and country. So flash recovery firmware, and dont do it when your device is on.
Here is how you should do it:
1. Download LG bridge on your computer.
2. Switch off your Device, pull out your battery.
3. Attach your USB Cable from desktop to mobile
4. Hold volume up button, and put your battery while holding it. It should switch on itself if the USB is attached and you are holding volume up before putting in battery.
5. Once its on Bootloader, flash firmware recovery from LG Bridge.

Thanks Dark$tar. I did what you suggested and the LGbridge reinstalled MM6.0 onto the phone. I then did a hard reset and nothing is different. The bluetooth functionality still doesn't work at all and any attempt to flash the phone with LGUP still givers the "TOT file is invalid[1]" error with every KDZ I have. Thanks for your help though, at least I know I can recover the phone with LGBridge should I need to again.

Glad to hear that I could help! Also, if your bluetooth is still not working, it seems to be a hardware issue. Now that you have flashed the stock firmware via LG Bridge, you can claim warranty and get it fixed!

Also, though I think you wouldn't have made this mistake but since you mentioned it installed MM, so I want to ask:
Did you click on firmware upgrade or the firmware recovery? Note that the firmware update will simply use the base OS files and will replace the new ones and recovery firmware will replace the entire OS (refurbished). The Recovery Option is on Bottom right, in form of text which you need to click whereas the update option is the button on the same screen in the center that you don't have to click. Both of them have completely different functionality.
If you have done it right, well then I am 90% certain its the hardware issue. But I believe that the firmware backup is likely to install the November's released version of LP not MM (unless LG has recently changed that) which is why I am wondering.
Yeah, I clicked the blue recovery text in the Bottom right corner. It definitely installed MM 6.0 onto the phone.
Also, I have found out the cause of the bluetooth issue and unfortunately I have to wait for the next Android update. There was a large discussion on code.google.com about the exact problem I have and the current workaround requires the phone to be rooted. I don't think it's possible to root the H815 TWN yet.

Hi, I have the same problem, did you find a solution to "tot file is invalid" error message?
No, I didn't. Every one I tried gave me that error. I just gave up in the end.
Hi Everyone.
I'm in a big mess.
My LG G4 showed as H815 in device information (But it was F500L) . It had 5.1 (LP).
To update it to 7.0 (N) I flashed the TOT file for N with version H815 thru LG UP.
Now it did complete to 100%. The phone rebooted and showed error like " Central App not loded" or something like this.
I tried again to Flash the TOT file thru LG Up. It went till 21% then shoed error command not recognized.
I triedLG bridge. It shows device as F500L.
Although LG Bridge says update available, it could not update either.
So the problem is I flashed wrong version. My phone is F500L and its showing "firmware update" when plugged into USB with PC.
In LG Up it shows as H81510H
Please guide friends....

Why u flashed the tot file?
For your Location (Korea ? ) there is an official Update to 7....
Look here: https://lg-firmwares.com/lg-f500l-firmwares/
or this Link: https://lg-kdz-firmware.com/
You should use LGUP again and flash back with stock 5.1 or 6.0 kdz, follow the link.
Hope will helps you otherwise reply

Okay, that Sounds good Yes really..
I think the Probelm is in LGUP´s dll, you must replace the LGUP_8994.dll with the L500F kdz from.
Download the Tool LG Firmware extract, Link from my GDrive:
https://drive.google.com/file/d/1NTzwI-qLBpIgTov5PC4THZJWbAOhJDO3/view?usp=sharing
Start the tool and load the kdz in, then you see some files in the tool. Mark the lgup8994.dll and extract it, close the tool.
The dll can find now in the Folder of LG Firmware extract tool, rename it to LGUP_8994.dll
Copy that new dll and put into C:\Program Files\LG Electronics\LGUP\model\8994
The old LGUP_8994.dll remove to desktop and put the new dll in here and start again with LGUP.
Please point LGUP to Refurbish and NOT to Upgrade. The old dll that was in the Folder is for the Nougat tot file and the H81520p kdz only.
Hopefully thats will works for you, normaly it should !

Well this is not working.
LG UP recognizes my phone as H81529a. So it doesn;t let me flash F500L rom.
When I extracted 3994 DLL from F500L KDZ and replace in LGUP folder and start LG UP. It shouts wrong version DLL.
Is there any way I can make LG UP to recognize my device as F500L and Not H81529a.
LG Bridge recognizes it as F500L though but it doesn't update my phone either.

Hmmmmmm
Okay, the H81529a Header says LGUP that is a G4 H815 with Anroid 7 ( 29a) on it. Okay, the LGUP_3994.dll wont work for your F500L kdz. By the Way..wich kdz you try to flash? is it a MM one or the Korean Nougat ?
On my H815 i had the 29a after flashing the Nougat tot file too and came back to MM ONLY with H81520p_00_0314.kdz other kdz for my H815 did fail too.
This Problem with LGUP is only the dll file...so you must find a working dll for LGUP.
Maybe you download the Korean Nougat kdz and extract the dll like the last posting before and flash the Korean Nougat, i think the Korean Nougat has 29a too, so LGUP should work.....
Or find a F500L20p kdz file...
I don´t know what to do yet. Sorry.

Well...
I have been able to sucessfully flash H81520p_00_0314.kdz on it.
It starts but no signal / network.
I'm from India so I think the version I flashed doesn't match with Indian Band.
Now what to do ?
In India following works :
2G network GSM 850 / 900 / 1800 / 1900 MHz
3G network HSDPA 850 / 900 / 1900 / 2100|TD-SCDMA
4G network LTE band 1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)

For my undstanding....
1) You have still H81520p_00_0314.kdz running on your Phone ? but no Indian Band ?
2) What Header is LGUP showing now?
If you have H81520p_00_0314.kdz on it, you are able to Downgrade to ever Version you want, H81520p_00_0314.kdz make it possible only !
So, find out your Rom for your Location and flash it with LGUP. Keep the 8994 dll it comes from H81520p_00_0314.kdz in the folder and flash.
After downgrade with LGUP (Refurbish Mod ) do a Over the Air update on your Phone or via LG Bridge and do "correct update Error" instead of "Search for Updates" and normaly its works.
Follow this Links for the Roms
http://storagecow.eu/index.php?dir=Xda/
https://lg-kdz-firmware.com/
If you are unsure what rom you must get, go to https://lg-firmware-rom.com/
and type your IMEI in and watch for the results.

Well
Problems just dont seem to end.
I hooked it up with LG bridge.
It showed model as "G4".
No version no code just G4.
I started to update it (thats before I read your msg)
Update stopped in between and phone turned off. I unplugged it and pulled out the battery. Restarted.
It showed LG logo and agained turned off.
I tried to reset by pressing Down vol n power button.
Options came to reset n I reset it.
Now again turned on. It showed optimizing android.
Stopped at 4 of 32 app and screen went blank.
Now LG bridge reads it as L500F at place of G4.
Hooked up again in download mode and LG UP disnt recognize it. Again restarted.
LG up recognized as H81520p.
I reflashed thr H815 20 p kdz.
Completed successfully.
But the problem is again same. It shows optimizing android and screen goes blank after 3 of 32 app or 4 of 32 app.
Have I messed up the recovery ?
I am able to go into download mode and LG up reads it as H81520p.

For my undstanding....
1) You have still H81520p_00_0314.kdz running on your Phone ? but no Indian Band ?
2) What Header is LGUP showing now?
If you have H81520p_00_0314.kdz on it, you are able to Downgrade to ever Version you want, H81520p_00_0314.kdz make it possible only !
So, find out your Rom for your Location and flash it with LGUP. Keep the 8994 dll it comes from H81520p_00_0314.kdz in the folder and flash.
After downgrade with LGUP (Refurbish Mod ) do a Over the Air update on your Phone or via LG Bridge and do "correct update Error" instead of "Search for Updates" and normaly its works.
Follow this Links for the Roms

If you are unsure what rom you must get, go to https://lg-firmware-rom.com/
and type your IMEI in and watch for the results.

I will do my Best my Friend.
I don't understand why the optimizing Process stops....
Maybe there is something blocking the process.
My only idea now is to flash Twrp on it and wipe all chaches. Davlik,Data and Cache and let the phone boot up and see what is going on. This is the working TWRP for G4 on H81520p
https://drive.google.com/file/d/1sOsVDs1vZzuvirWQ0ByFPZv9BC9Eu4yH/view?usp=sharing
But for twrp flashing the Bootloader must be unlocked. You can do this on lg developer page ( https://developer.lge.com/resource/mobile/RetrieveBootloader.dev ), type in your IMEI and you get a unlock.bin via email.
I think you know the process for Bootloader unlocking otherwise i will guide you.

Hi
Can bootloader be unlocked in LG G4 MM ?
Initially when i flashed nougat TOT on it, the firmaware update page was either in korean or chinese then after nougat TOT flash ot became in english.
Could it be that the recovery is also overwritten ?
Plz point me to bootloader unlock for it.
Many thanks from India

Hey.
Yes you can unlock Bootloader in MM too.
After the bootloader is unlocked, the Phone will reboot and do a Hardreset itself, you can´t do anything to block the Hardreset.
Notice: After flashing in any Versions the Recovery will be deleted too !! Example, if you have TWRP on the Phone and flashing any kind of firmware, the Recovery with TWRP in it will be deleting..thats normal in the flashing process.
BUT you CAN´T unlock the Bootloader yet ! You must enable the Developer Mod in the Phone first and set OEM unlock.
Your Phone does not boot up correctly at this moment, this Problem MUST be solved first !!
Did you try a Hardreset ?
Switch Phone off, pull Battery and place it back. Press the Volume down Button and keep hold and press Power Button and keep pressed, after LG Logo is showing up, release the Power Button for 1 secound but still keep Volume down pressed. Press Powerbutton again and hold pressed until the Green Android thing is showing up, release both buttons now.
In short: After Battery was pulled and replaced..
Press and hold VOL -
Press and hold Power
after LG Logo is showing up
Release Power 1 Sec. and press again and hold until Android puppy is showing, release both Buttons.
Now the Phone should boot up and do the optimazion process correctly.
If not, then i have no more ideas. Maybe flash a MM 5.0 Version over the MM 6.0 via REFURBISH option in LGUP
Hopefully something works for you.

SO Finally it's dead.
I tried to hard reset and the puppy appeared and then it rebooted. Again went to optimizing apps. Stuck at 14 of 32.
Became unresponsive.
I pulled out the battery and reinserting after 20 sec.
Nothing.
After several battery removal and reinserts, I managed to get it in download mode.
I was trying to Flash H815 20p KDZ again as it was working initially. But at 50% process of flashing, it shows error of USB Disconnected and phone screen went blank.
Since then it was neither starting nor getting in download mode. Tried everything.
It doesn't even show after connecting to PC.
Dead as dodo.
I looked at it with more attention. Removed the battery cover saw the model on mobile body,
it has model no H811
On box the model no is H815
LG Bridge recognized it as F500L.
IMEI No search says its F500L.
So basically it looks to either a refurbished phone or a fake.
I bought it thru eBay on 18th Jan 18. So I had to claim refund against a faulty product.
I suppose I'll get a refund, I will skip replacement as it's likely that the seller might again push a refurbished / fake phone.
End of the story till then.
If I dont get a refund I'll revive the thread.
Thanks to FOTO AG and XDA for support n advice.

You should have hexedited a F500L tot(wich is your motherboard version) and changed the LGX to H815, saved the file and then flashed. That could been solved your issue and turned your phone back to F500 with a functional and booting system
Hi Everyone,
I tried to find solution here on xda and googled the problem but no luck. Please help me in getting my phone back to stock.
Problem:
1: Phone is actually H818P as per IMEI.
2: Phone settings shows as H818N (Happened in attempt to correct rare ghost touch issue by flashing multiple firmwares. LP/MM/N, only noticed when first KDZ started giving error of invalid kdz.)
3: Network mode selection is not correct anymore although no issue in signal reception or IMEI. If I change RAT selection to GSM or GSM/ WCDMA through hidden menu *#546368#*xxx# then it shows "Null" in front of selected mode in Settings/Mobile Network under Nougat and all modes will show un-checked under MM/LP. (Only GSM/WCDMA/LTE auto) will show properly checked when selected through hidden menu under LP/MM/N.
4: Minor yellowish closeup pictures with flash on in low light under N. No issues under LP or MM. (just info)
4: At least i could figure out the solution of ghost touch for mine H818P, it gets to almost none under V20h MM (Tested for 1 day and comes back as soon as N or LP is pushed in.)
Attempts done to correct it:
1: Tried flashing through LGUP/ LG Flash tool 2016 but both won't flash unless phone model is changed in kdz so once phone boots up then again H818N and stock tot automatically takes it as H818N and configures accordingly. If i change model in tot then phone flashes but won't boot. (Flashed V10d, V10i, V20d, V20h, V29a-815N)
2: Flashed 3 times stock LP V10d kdz (w/out editing) with Flash tool 2014 but on boot up again H818N.
Please help with any possible way of getting it back to H818P so minor issues could be resolved when it will flash/ configures as H818P. (As I shall stick to V20h MM)
Is TOT like "LGH818PAT-00-V20h-AME-XX-OCT-19-2016+0" good to flash both N and P variants as I can see inside of tot that it contains both P and N model configurations. (I never need to edit a H818P tot to flash.)
Thanks guys, and waiting your support
Anyone..?
bump
read phone info while the phone in download mode you will get the correct model
Thanks..it shows h818n now but it showed only h818 when installed v10C kdz (chinese region) LP in attempt of fixing it.
Thats what i could achieve max, never shows h818p.
Changed with G5 not using G4 anymore.
