You can flash the kdz (stock file) for the update you have available by using LG Flash Tool 2014 (do a Normal flash).
The instructions and tools required for flashing a KDZ file are in this thread
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
The steps are roughly:
1. Find and download the correct KDZ file for your phone by following this link (replacing IMEI at the end with your IMEI)
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
2. Flash the KDZ using LG Flash Tool 2014
3. Once finished flashing and the phone has rebooted, re-install TWRP and flash root
Cheers.

Thanks I'll give it a try

LGUP - NEW!!! - INSTALL KDZ - MM or LP - FACTORY RESET/UPGRADE

NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP from here http://www.filedropper.com/g4 or here https://www.dropbox.com/s/d2dw48uqh4hku8m/G4.rar?dl=0 or here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.
THANK YOU FOR THIS Killerdog:good: <~~~To Modify This File You Must Have Root!!
For me it's show in LGUP as unknow device.
reboot my phone, remove battery and anything else don't work.
I install LG Bridge to test, and nothing seem to work.
After make some test and search, i find some info modified by S3V3N into his rom (cust partition) that he have modify into this file:
/cust/OPEN_COM/cust_OPEN_EU.prop
Code:
ro.lge.swversion=[COLOR="Red"]some info[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]some info[/COLOR]
change to
Code:
ro.lge.swversion=[COLOR="Red"]H81510c[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]V10c[/COLOR]
restart my phone and woow it show correctly in LGUP and i can refurbish my phone.
TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient
If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

INSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.

Not sure but I'll put that in the op cheers.

Do you need root so use this method to upgrade to marshmallow ?

H81520A_00.Kdz flashed (by upgrade option) succesfully. It takes 10-15 mins(longest part is "android upgrading" screen.), and i lost root access. By the way root access is not necessary for upgrade.

So since it wasn't clarified, I'll be the one to ask...
Will this work on a unit without root (which is yes according to the OP), and without a bootloader unlock, ie the Taiwan (TWN) variant of the H815.
I completely understand it's a complete wipe and root will not be retained.

I would also like to know about this..... will it work on a unit with a locked bootloader... TWN variant?

downloaded from a different mirror re flashed no problems

Hello downgrande wokrs?

Problems with Safety Net

After the last OTA update, my Moto G5 started to boot with the following warning:
"
Your device has failed verification and may not work properly.
To learn more visit:
motorolacom/unlockbootloader
ID: N/A
Your device will boot in 5 seconds
"
It also started to restart randomly.
I did some research on the web and found out that this warning appears when someone unlocks/roots the device.
The problem is that I aver never unlocked the bootloader or rooted the device.
When I boot to fastboot it says "OEM Locked" and the app DevCheck says that I am not rooted.
It seems to me that the update corrupted something and now some piece of software flags my device as unlocked.
Besides the irritating screen, some apps are not working properly or cannot be downloaded from the store.
I tried to reset to factory settings and wipe caches. Problem still happens.
I'd like to know if you guys know a solution for this problem.
I saw on another post that this problem was happening on some Verizon Moto Zs and they provided a software to reinstall the rom
Unfortunately, Motorola has not released a software to do the same to unlocked devices.
My ROM version is: NPPS25.137-33-6 (yeah, there is an "S" that I don't find in the roms available here)
The baseband is: M8937_8000.122.02.45R
(CEDRIC_BRAZILDSDS_CUST)
I was thinking in loading the rom into internal memory, reboot in recovery mode and flash the rom using the option "Install package from zip".
Do you know if it would work without an unlocked bootloader. Is it safe?
Thank you for the help,

Don't know if you can flash the boot logo without an unlocked bootloader but if you can here it is
Put phone in fastboot mode
Download logo from link below
Enter the following in a windows command prompt where you have fastboot files (Google to learn howto install Android sdk) & the logo file
Code:
fastboot.exe flash logo logo-g5-fix.bin
http://drive.google.com/file/d/0B-idWfPYugGvREJaR3B0UFIxUkU/view?usp=sharing
If you can't then you have no option but to wait for Motorola to fix it if you really haven't modded your phone

TheFixItMan, I really appreciate your answer.
But in that case wouldn't I just be changing the warning screen?
The problems with Netflix and other apps would remain.
I need something to fix the cause of the problem.
Have you guys heard about that problem before?
This guy had the same problem, but verizon patched it:

You can go back to stock using ADB update or by flashing VERIFIED images in bootloader mode. This will work even when bootloader is locked.

To flash using bootloader I need just to copy the .zip in the internal memory, reboot in reboot in bootloader mode and select the option "install from .zip file"?
Where do I find the verified image for my device?
If I flash an unverified image will my device brick ou the bootloader will present a "impossible to procede" screen?
Thank you for the help!

you can flash what ever you want in fastboot -
However - In terms of firmware, if you are trying to flash incorrect firmware then the verification check will fail and it will not flash
Just don't flash a new bootloader if you are worried about it - its not needed unless you are upgrading an android version and that version has an updated bootloader

So I am safe if I follow these steps:
Manually Update Android Nougat for Moto G5 (NPP25.137-33) via Recovery
First of all, Go to Settings –> About Phone –> Tap on Build Number 7 Times.
Go to Developer Options –> Enable USB Debugging.
Save Stock Android Nougat rom for Moto G5 and save it in Internal storage.
Reboot Moto G5 Plus to Recovery Mode.
Select Apply Update from SD Card.
Select the Downloaded ZIP file from SD Card.
Wait until Installation process Completes.
Once the Installation completed. Reboot the Phone.
If my ROM is a wrong version, will the bootloader detect and deny instalation?

if you are talking about an official ota update then it will fail - you cannot update like this
An offical ota zip requires a non rooted device, unmodified system partition and stock recovery
you maybe able to download the ota update and save it (its in the cache partition)
then use flashfire app to install it
note if its a custom rom than recovery mode will allow you to flash any zip and will flash anything unless the updater script specifies a certain build.prop target eg phone model or other criteria that would stop it flashing if it was false
If you want to flash firmware you need the firmware image and flash it via fastboot

You need firmware that matches or exceeds your current firmware version - you cannot flash a lower firmware version

1. Backup your important files and make sure you have enough charge.
2. Download this to the INTERNAL storage of your phone (not the external as card): http://forum.xda-developers.com/g4/development/stock-h815-20g-images-kdz-flashable-t3450503
3. Boot into TWRP recovery. (Use the quick boot app from the play store if you're having trouble). If asked if you want to restore to factory settings, select yes.
4. Flash the downloaded zip file. Be patient as it will take a long time. Don't pull the battery.
If this doesn't work for you, try the kdz method: https://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848

Your IMEI number is written on the back of the phone, under the battery. Write it into the box on this website: http://www.imeipro.info/check_lg.html
The third line tells you your phone's model. Mine is H815, for example.
Then search XDA/Google for Kdz file.
Failing that, use the LGUP tool to restore your phone. You're not the first to have this problem and everything has been answered before if you search for it.

You need to flash your proper firmware. Which model are you? (xt1952-?) I also need to know your carrier and country. I'll link the right firmware for you.

it's the xt1952-2, I flashed the latest firmware available for it from lolinet.
it's from brazil and has no carrier.

The firmware on the lolinet seems to be the latest.
How did you try to flash the firmware? As long as the bootloader is locked the most devices only accept to flash the complete firmware images. They should be flashed in the same order as listed in flashfile.xml inside the zip.

I don't know much about how to use ADB, I got it from a stockrom, that had a tutorial on how to fix failed startups.
https://drive.google
.com/file/d/1G8AeMUfFbAroan5S1mpojyMYpUvKsR1N/view?usp=drivesdk
I just threw these files onto the firmware's files' folder.
How do I flash It in the correct order?

1. install ADB/Fastboot tools
https://forum.xda-developers.com/showthread.php?t=2317790
2. boot into bootloader (when power off, hold Vol- and power) and connect the device to your PC
3. A short introduction to ADB/fastboot:
While in bootloader menu you can only use the command "fastboot + <options>" to communicate with the device. Type
Code:
fastboot help
to show the options for this tool.
First of all extract the whole firmware zip into the ADB/fastboot folder on your PC. Copy also the attachment into this folder.
In this file you'll find all the flash commands you need to flash the new firmware. I extracted them from your current firmware .zip for the build no. QPYS30.52-22-2.
Run it as a batch script on your Windows cmd line by typing
Code:
bat flashfile.txt
. The other option would be to run all the commands manually.
As you can see in the script the "HLOS issue" affects your modem partition. At least you need to flash the NON-HLOS.bin to it. But I guess it wouldn't be possible to flash only this single partition while your bootloader is locked.
That's all. Good luck!!
