What did you flash, what error does it display, is it "secure boot error", which version of g3 do you have, can you access recovery, do you have TWRP...?

i used ioroot to root the g3 (D855), and i flash with twrp-2.8.0.0_d855-signed.img. Yes i believe it was the secure boot error. After that the notifications lights at the topped flashed blue and red i turn the device ofd to restart and it will not turn on i have tried both to get into the recovery menu (power+vol down) and download menu (power+vol up) neither of which is working.

Ok... Lets start with battery pull in and out.
Even if you do recive secure boot error for booting to the unbumped recovery you should be able to boot to the OS, try with that.
If this fails, do the battery pull again and lets try to get you to the download mode. The way you specified (power+vol down) is incorrect I belive. What you need to do is hold the volume button WITHOUT the power button which will be followed by connecting the device to the PC with installed LG drivers.
If that works you could flash stock files, follow the thread: http://forum.xda-developers.com/showthread.php?t=2785089
Check in device manager how is the phone detected what mode ...

Does it get into download mode? For this one get the battery out and wait 2 secs. Plug it back in. Be sure to have an USB Cable ready plugged in the back of the PC (NOT IN FRONT HUB and be sure to be the original Cable). Hold Volume UP and Plug the cable. Keep holding Volume UP until you see download. Tell me if you see the Firmware Update screen or it is a security error.

Not entirely sure why this has happened but im getting secure boot errors when:
1. I just turn the phone on.
2. Vol up + USB
3. Vol down + power button to get to factory reset.
After that it is the usual black screen with blue and red lights.
I cant use any button shortcuts to get anywhere, is there a way I can get the pc to recognise the device from this state?
I have the same problem. Like and idiot I deleted boot.img, aboot.img and recovery.img and then I realized that I didn't have the backup done. So I disconnected my device from the PC and nothing happened. Just turned off. The weirdest thing is the pc recognize my LG as a "LG Android USB Device". And I can't enter in download/fastboot mode
Any suggestion?
Sailing in the same boat, any help will be great, have a very expensive brick with "secure boot certification" error.

I flashed something that was incompatible with my version of android and my phone is stuck in a boot loop, aside from that my power button is broken so I cannot simply press volume down and power to get into recovery. When I use the command "adb devices" on my computer while on the boot screen my phone comes up but says it's unauthorized. I can get into download mode though. Do I have any options besides re-installing android altogether from download mode?

Download KDZ and use normal mode to flash it
It should overwrite all partitions except /data and your phone will still retain its data

How did you damage your power button mate? DAMN !!! That's horrible! Send the phone in for repairs! You can't really operate the phone with a broken power button.. Try this link to get your device working again.. I'm afraid that you need to download the appropriate KDZ file for your device and use the LG Flash tool to restore your device.. Good luck!!:fingers-crossed:
Hi, as the title says I am completely unable to boot to download mode on my E988. I have literally tried every possible combination of button pressing but nothing works. I have tried rebooting to bootloader from cwm but that doesnt work either, all it does is reboot, show the LG logo, then it reboots normally.. I have tried using terminal emulator to use the command "reboot download" but it doesnt work either, all it does is reboot, show the LG logo, then it reboots normally again. It seems that I am completely unable to access it at all. Any ideas?
Have you try with one end of the usb cord already plug in either your computer or phone, hold down both volume buttons, and plug in the other end. This was the only way down load mode would came on for me until I fixed the phone.
Yup I have. No combination of keys and button pressing seems to work for me it's odd.
Sent from my LG-E988 using XDA Free mobile app
To add on to my previous post, when I do the method whereby I hold vol + and vol - and plugging the usb cord in without my phone's battery, a message shows up when it is detected saying that a "...usb device has malfunctioned...". My phone will then just keep showing the lg logo over and over again causing the message to pop up again and again as the phone is detected and then not detected and the cycle just repeats itself. I have tried to reinstall lg drivers but nothing seems to work...
Edit: It would seem that the phone is indeed trying to boot to download mode whether I use the key combination or command, but it is unsuccessful in doing so and just reboots. Has anyone ever encountered this problem?

Your boot loader is broken. Gonna have to get to the down load mode and reinstall either the or the stock. You can probably flash the recovery with .IMG file with lg flashing tool. Nerdy blond's twrp is one of those files that you can use. You can even try installing it first with the adb shell command, you can get the instructions at the same place where you download.

Thank you for replying.
I cannot do anythings since I cannot enter into download mode.
I pressed volume key + and - and insert the usb cable to computer. There is nothing happened, computer dose not show the devices attached and the phone stay in the LG logo screen.
Also, I cannot use adb commands to force the phone enters into download mode as it shows nothings under "List of devices".
Is there any methods I can go into the download mode???
Thank you!

If your phone shows LG start screen, it should go into Download mode. I had similar problem few days ago while I was testing some kernel patches, it just froze on the LG screen. Solution was to unplug it, remove it's battery, SIM & SD (you don't have to remove SIM & SD, I just work that way) , make sure it's off, return battery back, press Vol + & Vol - at the same time and plug-in the USB cable.
Before that, make sure you have installed LG Unified driver (can be obtained via LG's software from support site), because without that Windows won't recognise your device.
After that, once you make your phone usable with Freegee/whatever you use to install initial recovery, flash official TWRP, because others are too old - that Philz CWM is old but still working with Lollipop but not work good and is tends to lock itself into a bootloop if you use hardware keys to enter; that other one, from GPRO_recovery APK is not supported and not working well (for me since day one), so it should be replaced as soon as possible.
Also, I can suggest you to flash your phone from stock 4.1 (not KitKat), root, flash recovery via freegee and after reboot update to latest official TWRP via Flashify.

Thank you for your detail reply.
I have tried to reinstall the LG driver and try to enter download mode again.
The screen is still stuck on LG logo and I cannot find the device in hardware manager (cannot recognize it).
I cannot do anythings until it can recognize it.
(Is it the bootloader is broken? and can I fix it?)
Thank you very much and waiting for your reply soon.:good:

Which version of Windows are you using? It should be displayed under Serial ports in Device manager (named something like LGE Serial device) and LGFlashTool should recognise it immediately. I can't make you a screenshot/check for real name because I'm running Linux right now and can't reboot.
Also, try with another cable/port, remove all other android drivers you may have (Samsung's, Google's...) and disable antivirus.

OK, it doesn't enter download mode. So, step by step:
- remove battery and leave it for 15-30 seconds, return battery
- press Vol+ and Vol- at the same time and keep them pressed,
- plug USB cable in while keys are pressed
It should immediately put you into download mode, with no LG screen, just black screen with gray box and red text I've described to you.

So, whatever you try to do, phone just shows LG logo, not even a message in an upper left corner?
I'm running out of ideas. I have exact same variant (E988) but only time it didn't want to enter download mode this way was when cable I was using was broken...

First remove your battery then insert battery dont power on mobile . holding the volume up, plug in a microUSB cable into your phone.
Make sure the USB side is already plugged into the computer
You should start to see "Download Mode" for a few seconds and then it will show "Firmware Update". You are now in Download Mode!
Open LG Flash Tool and Put your dll and tot files in and use Board DL (Very Important)
after u success
It should boot into MiniOS just hit ok. Push power button plus touch the screen where it says Normal boot+(power)
done
This is not working for me. it says waiting for connection, please help
i am frustrated !!!

Try unplugging and plugging back in and ensure you are on PORT41 for the device driver. After you do that and in Download Mode, then unplug and replug USB.
Also do not use USB 3 and try another port if you still have issues.

I have same issue in my LG G3 D850 I have apply your procedure Thanks It works ... first time the setup screen completes but when i powered off mobile and insert the sim and then powered on its again going to miniOs again i Normal boot+(power) but now boot looping auto ... what can i do now ???
For me who had the same issue, I just rebooted the device back into download mode and the LG flashtool resumed automatically. (I did not close or stop the process from the LG flashtool when I got this message).
Once the process resumed automatically, I still got download fail.
I can see whenever the device reboots, the modem disappears from within device manager after getting to the "Factory Reset 2" screen.
Any advice?
Update: I tried about 7 times to get it flashed. I ended up just restarting the phone in normal mode and strangely voila it works perfectly. Even though the software said the flash failed, it still worked. Thanks anyway!
