[Q] Can't change into download mode LG G3 D855

Hey Guys,
I want to flash the stock rom on my LG G3 D855, but somehow lgflashtool cant change into download mode. I tried to flash with the .kdz file but it doesnt work either.
And now my phone is stuck in the firmwarte update screen. I cant do anything when I try to turn it on it just goes back into the firmware update screen. I tried to do the hardreset with the buttons but it doesnt work.
Can someone please help ?
EDIT: Hey guys I solved the problem by returning it to telekom (my carrieer) and they send me a new LG G3 on the next day. But when I tried to flash my G3 with the .kdz method I didnt put the .kdz file into the same folder as the LGFlashTool, maybe that was the reason why it didnt work.

What method did you use?
If you used the .kzd method (http://forum.xda-developers.com/showthread.php?t=2785089) dont forget to put the .kdz file in the same folder as the LGFlashTool
If that doesnt work, you should go and replace it.

[Q] G3 - Secure booting error, Dead; No recovery, No Download

Hey all,
I restarted my phone yesterday and it was stuck in a boot loop for some reason. I tried to factory reset, but doing so still resulted in a boot loop. I then proceeded to attempt to flash stock, but the flash tool crashed while during the process. When I try to boot to download mode now, I get "Secure booting error, Error!: Boot Certifcation Verify". I know this also happens on the G2, and I know the process for fixing it. But when trying to use the same method with the G3, I can't access my filesystem from Linux. Any help? Thanks.

I was rooted before updating to lollipop, then tried to back dowk to KK with TOT and this happened, so I dont think I am rooted any more.
The better question is: do you have TWRP (custom recovery) installed? If you do, your phone can be fixed. If not, you are probably screwed.
Basically it sounds to me like your phone managed to flash the updated Android 5.0 bootloader but didn't update the LAF image (download mode). The old download mode doesn't work on the new bootloader, it gives the error you are experiencing.
Because you still have a LAF partition, and presumably a recovery partition (even if they are not working) you cannot access fastboot mode.
In other words, there may be no way to fix your situation.
As the hardware is fine there must be a method, but it might be something only LG can do.

I'm in the same situation now.
I was bumped with TWRP and CM12 installed. I wanted to unroot and go back to stock. Started a flash with LG flashing tool, but it was taking ages, so I unplugged the USB cable in the middle.
Now whenever I boot via either VolUp+USB or trying to get into a recovery I get secure boot error.
Is there a way to fix this ? Or do I need to send a phone to LG ?
This has happened to me today. Downgrading got stuck at 3%. LG Flash tool said to remove phone and plug back in. Any way to fix
Also, does anyone know if downgrading voids warranty or anything?

I didn't find a way to fix it, so I've just sent it to LG repair shop. They haven't yet looked at it so I don't know how much would it cost.
People just tell the service center that you were upgrading from KitKat to Lollipop when the problem happened
Evidence wise it support your claim since the OTA from KitKat to Lollipop overwrites the aboot, sbl, laf and recovery partitions and service center people ultimately cannot tell between failed OTA and a failed KDZ flash

Did you get an answer on the cost yet? I have the same problem, so I'm probably looking at the same resolution as you.

solution for no download mode
Hi guys.
If you cant enter into download mode then you need to force your g3 in to qhsusb bulk mode by shorting the test point.
When you short battery must be removed.
After short your phone will be detected as qhsusb bulk mode.
Send me msg in pm for further help.
If u dont know the test point then let me know.

Hi guys, i have a ls980, the phone does turn on but not get through the lg logo and after that keeps trying to install an update. i've allready tried to flash 4 times 2 diferents "*.tot", flashes ok but then try to configure the new system to boot up but it shutdown and do the same everytime you turn on the phone. when u entrer to the recovery it says that fails to mount every partition or folder of the system even when you hard reset the phone it says that cant format partitions and make sure it is mounted.. so what do u guys think i need to do?? and btw after i flash the .tot file the 4 times i tried, the phone still said that im root.

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.
i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

Call LG and tell them you need the kdz to restore your G4.

Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ...
