I don't know if you managed to find the solution to this, but for anyone else out there that hasn't, just download the AutoRec app. Fixes it in seconds and flashes TWRP Recovery.
need help

It's a bootloader issue, for me it was. If you can enter recovery, flash JB Bootloader or KK Bootloader, whatever your rom needs. it worked for me.
Autorec

Hey man, if youre able to boot into your rom, try this,
AutoRec
http://forum.xda-developers.com/showthread.php?t=2715496
It sorts of reflashes your boot recovery to TWRP, works for me when i got the same error.

Thanks for this. I just ended up back on a (brand new, mind you) G2. I've had SO many problems with rooting, recovery, download mode, etc... I have TWRP installed, stock ROM and somehow ended up getting the secure boot error only when entering download mode. My phone was booting, recovery was working, etc - just download mode seemed toasted. AutoRec fixed it - so, thanks for posting this!
I had the same issue, if some of you want to know how I fixed it these steps might help you too...
What you need is :
Any versoin of stock kdz. I used 11a. GET FROM HERE
LG Universal drivers. Get them here
If you have verizon get your driver here
KDZ Flash tool. GET IT HERE
1- Power off your phone completely ... remove battery etc...
2- Plug the UsB cable to your phone and your computer.
3- Hold down volume up and power button and enter in the download mode
4- If you in download mode you can now flash any KDZ file using the method in one of the guide above or find it using google.
after flashing you will have the stock rom installed. I was on 4.2 and for some reason i was not able to root with "ioroot" until i updated to 4.4!
so make sure you are on 4.4 to do the root
later you can install any recovery. I installed autorec.apk and then booted into recovery and flashed latest version of twrp
thats about it.... but don't install MIUI that rom is stupid

have you try vol down + power button ( LG Logo ) then Hold Vol down + Power ? till you get to factory reset ! and power key again will take you back to recovery
WOW! Thank You soooooooooooooo much! I flashed a cloudyg3 backup from VK Rom and got this error but this method worked!
Just download AutoRec and choose to flash TWRP. Worked for me.
Hello Forum,
first of all, I used Google to find out what to do with my problem, but found nothing. (Just for those, wo wanna tell me how to use the serch )
So, I am german... my english is not perfect but hopfully you will understand it.
My Phone:
LG D802, rooted, with latest TWRP installed
My Problem:
I can flash any CM based ROM but if I try to flash CloudyG2 , MIUI or Flyme it just get suck at booting.
I press the powerbutton, the screen turns on, the LG logo appears and a second later it just turns black.
After a while I figured out, that the phone boots into a "Fastboot mode without lines showing on the display" - And if got a QHSUSB__BULK which i cant fix with SRK tool because it´s simply not detecting my phone.
The funny thing is, I can still enter recovery to flash back my CM 12 - and its fully working - but I dont want that.
Flashing .kdz with LG Flash Tool 2014 isnt working too.
It only shows up the "normal" error message and if I would like to retry. And yes I waited for like 20 minutes at that state and still nothing happens.
Hopefully someone out there who can help me
Greets,
Ims
I think you have the wrong bootloader...
Flash the right one (or the patch from the d802 thread), reboot recovery (not system) and try again.

Can you access to download mode or fastboot mode? looks like qhsusb is corrupted. If that is the case you could try to follow this video tutorial to fix it. It is kind of the last resourse to fix a brick but it works, be patient I used this metod two days ago, bricked my lg g2 with simply rom v2 and my pc didn't recognized the phone, not even as an unknown device.

Does the led notification blinking when you put the charger on?
Sent from my LG-D802 using XDA-Developers mobile app
Thanks
No it doesnt blink.....but I will try the other guys think and see.....thanks for your interest
