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.
I have just flash the custom 5.0.2 ROM using philz touch 6.48.4.
After I flashed the ROM, I reboot to the philz recovery and flashed back to cwm 6.0.4.8.
However, the device stuck on the LG logo screen.
I have try to enter Download mode/Emergence mode/Hard reset mode/Recovery, but all of them I cannot go into.
Please help! Thank you for your helping!!

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...

I have changed the cable, but it is the same.
Hi guys,
I was running CloudyG3 2.5 on my D855. Today I wanted to go back to stock using LG Flash Tool with D85520h firmware file (lollipop) (in Windows 10). It got stuck at 4%. After waiting for close to an hour, I just unplgged the device. Now when I power it up, I get the secure boot error message and it starts blinking the notification LED (alternating red and blue). Going into download mode also brings up the same blinks, as does attempting to go into recovery mode.
All the threads I have gone to seem to assume that the phone can boot, or enter recovery mode or enter download mode. My phone can do neither.
I desperately need help.
Thanks in advance

Thanks a lot mate. I used the willcracker tool attached in the OP of the thread and it worked like a charm. My phone could go into the Qualcomm HS-USB mode but one of the following factors could have been at play:
1. The BoardDiag tool I was used was fake (as mentioned in the thread you referred me to.
2. The PC I was working on has all ports as USB 3.0 (I'm not sure if that was issue or the fact that I had other devices connected-- just a mouse adaptor, but I could see my phone in Device Manager)
So, I went ahead and changed all of the above: used the newly-found BoardDiag (willcracker), on a another PC with a USB 2.0 port and made sure no other devices were connected.
My phone is now back to life!
Hi, it's my first time posting here as I was unable to find a solution looking at similar threads.
Anyways, I was trying to install another ROM on the G4 but I think I messed up deleted everything entirely and got bootlop and reboot. I'm not exactly sure what I was doing as I'm new to these things.
What leads me to believe that this is not a hardware issue (as widely covered) is that during the bootloop, there's a tiny little green android in the middle of the screen with a small 3D box on belly.
When trying to solve this issue, I've tried:
Volume Up + Power to enter Download Mode
Nothing happens - back to the green droid
Volume Up + Power + USB to computer to enter Download Mode
Nothing happens - back to the green droid
Volume Up ONLY + USB to computer to enter Download Mode
Goes in Download Mode for a few seconds, but then goes back to the green droid
Volume Down + Power to enter Recovery Mode
Nothing happens - back to the green droid
Volume Down + Power to enter Hard Reset Mode
Allows me to factory reset, but then back to the green droid and bootloop
Connecting the G4 to the computer to see if phone would be available in device manager -
Not found
Nothing I've tried seems to shake off the little green android.
The phone doesn't connect to the computer at all.
Here's a video: youtu(dot)be/MfnkhZTPOz0
The top left of the G4 says "Bootloader State : Bootloader Unlocked!"
Here's a clearer image of the green android: android-hilfe(dot)de/attachments/2012-09-22-03-41-16-jpg.124036
Any suggestions?

From the thread you gave me it says 'YOU GET QHSUSB BULK MODE IN DEVICE MANAGER THEN INSTALL QUALCOMM DRIVER'.
But unfortunately, when I connect my G4 to the computer, it does not register 'QHSUSB_BULK'. In fact, it does nothing at all. The phone keeps rebooting and the computer does not detect.
So I cannot get either 'QUALCOMM HS-USB 9008' or 'QUALCOMM HS-USB 9006'.

You're still soft bricked, just force your device into download mode and use LG Flash Tool to return back to stock and start again.

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.

Thank you very much...now the phone is back to initial state. This what i've done:
1. Download LG Flash tool from http://lgflashtool.com/
2. Download LG USB Drivers from http://lgflashtool.com/
3. Install LG flash tool and LG USB Drivers
4. Plug usb cable to phone
5. Hold volume buttons and then plug the usb cable to PC (i use win 10)
6. Voila, the Download Mode icon is showed up
7. Run LG Flash Tool (Administrator privilege) & follow the instruction (i use e988 v20c stock firmware)
8. Phone back to normal (only if you use the correct stock firmware)
A very big thanks to ShadySquirrel
Hopefully this thread can also be used as reference for anyone who has the same issue as i had
