Try reflash the phone using the unrooting method mentioned in

0.Restart phone in emergency mode= hold the volume "down" and insert the USB cable(When phone is off)(Will Have Yellow Screen)
Install msxml
1.LG Drivers MUST be installed.
2.Plug The Phone in Emergency Mode.
3.Open KDZ_FW_UPD.exe
4.In Type Select 3GQCT , In Phone Mode Select EMERGENCY

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.

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.
So after installing cyanogen on my phone for the first time it all worked fine but I had no mobile data/signal at all, so I decided to try something else, but once I tried the install failed, and I didnt have access to my SD card from recovery mode, so when I tried to reboot the phone it just went into the LG logo and now its stuck at the battery screen. I've no idea how to get back to recovery mode, I can only get into emergency mode, PLEASE SOMEONE HELP! :crying: :crying: :crying:
If you can get into emergency mode, that's enough to save your phone! You can flash your phone with stock firmware (pick the one you need from this site: http://lg-phone-firmware.com/index.php?id_mod=13)
You can probably find multiple threads on how to flash a KDZ file to your phone on this forum!
Good luck!!!

you didn't have signal because you probably didn't have v20baseband flashed. You can enter emergency mode by taking out phones battery ,holding vol up and connecting phone to usb. Then flash this with kdz http://forum.xda-developers.com/showthread.php?t=2176430 ,after that you can try flashing cmw again but you will need to change baseband to have signal if you come from ics(v10) to JB+(v20)

I need help from you guys. I followed this guide http://forum.xda-developers.com/showthread.php?t=2673736. The moment my phone stopped to work is when I wiped system,cache,dalvik and data and Installed the rom on step 6.(4.4.2 kitkat). First what I got was the white letters saying fastboot mode started and udc_start(). That was all I got. After that I tried fixing my problems with factory reset which caused more problems then
I thought. What I have now is a phone without anything working on it. I can't acess my recovery because when I try it says factory reset(yes/no). When I click yes nothing happens and it just sends me back to screen now without udc_start(). Now I only have fastboot mode started without anything. I also tried holding the volume up key and going through the download mode and fixing it like that but when I try it it starts that little download mode and it just quits and sends me back to a page with a white text where I can't do anything. If someone could be so kind and help me fix my phone. Please help. I've did a factory reset using adb in recovery like this adb shell
recovery --wipe_data
device is : LG G2 d802
Solved with help
Many thanks to @bender_007 for his amazing help with laf.
So basicly what bender helped me is with getting the download mode to work and I found my way after that even though the download mode was stuck I still managed to do it
Okay so I'll explain step by step how I fixed it.
1. First thing to do is get this awesome files provided by @bender_007 Download:https://www.dropbox.com/s/ad1c592k3h3a1d1/paket.zip and to connect your phone on usb to be connected with your pc. After that you want to get your phone in fastboot and if you have the same issue just turn on the phone and it will get you there. After that extract the file provided by bender_007 and start the file called RUN THIS.bat. It will do all the work for you or basicly it will delete your current laf file and replace it with working one.
2. After doing all that you want to restart your phone with holding the power key and when it starts to boot(LG SCREEN) hold volume up. In the centre of the screen there will be a icon displayed with loading. Well my never loaded but it doesn't matter. It is the same if it loads or not.
3. Third step might me the longest depending on you. If you do have the R&D test tool it will be easy. Now you just want to get back to stock so you just need to follow this instructions http://forum.xda-developers.com/showthread.php?t=2432476. The instructions are very detailed and it will be easy to follow. It will take some time to finish and it will restart automatically. After that your phone will boot up and start . I hope this will help someone and I'm so glad @bender_007 helped me with laf filed. Many thanks. I'm not responsible for anything I'm just trying to help and it worked on my phone LG G2 d802
Also thanks @hyelton for providing files such as stock,R&D test tool and many other usefull things
The package is only for d802 though. :good:

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.
