How do I fix this? I'm on SU640...
I already tried removing the battery, turning it on just goes back to download mode...
You will probably need to flash it again with the LG tool. See the unbrick thread in this forum, you'll need to use that to flash the Korean ROM again.

p930 able to flash korean rom, but why cant we flash ice cream korean?
Forgot to update, fixed it... This happened while I was downgrading from 10L to 10f, what I did was:
1. Download new kdz(maybe it was corrupt)
2. Download the tool
3. Install sxml.msi
4. Install LG united drivers
5. Connect phone and let it install drivers
6. Extract kdz to C:/ don't put it in more folders also the tool. I think the shorter path helped.
7. Put phone in download mode (Mine was stuck there)
8. Run the program, click cs_emergency
9. Choose kdz
10. Launch software.

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

Hi, I solved my Problem bei using Google Universal USB Drive. There it's possible to specify your item and edit the right ID's. There is a description in the net. After the USB ist connected now, you can normally Flash your Gadget.

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
