Can not enter download mode - G2 Q&A, Help & Troubleshooting

I stupidly accepted an LG OTA on my G2 running Rayglobe.
Now the phone just loops into CWM and won't enter download mode either.
Bricked, or is there a chance of survival?
Thanks

Hey bud. There is still hope as long as you can boot into recovery. There's a way to push adb from your pc. It should be somewhere on the forums. I'm afraid I can't help any more than that.

secure booting unsuccessful
Cause:
and then this keep happening. I can go in to firmware update. Nothing much. I tried to use LG g2 stock guide, but no luck either.
When I thought I bricked mine I tried using this

Its tricky but it worked for me when I couldn't get past bootloader. All you need to be able to do is get into download mode.
Just FYI don't ever take OTAs after flashing custom ROM. They never seem to turn out well.

Thank you guys.. I got in to recovery mode and install my back up. Don't know how i got in to recovery mode. I kept pressing different combination. Once again, thank you.
Bricked in a weird way
I think I bricked my phone in a similar way except I can't get into download mode or anything the only thing I can do is go into the hardware control mode and the factory reset mode when I try to factory reset it scrolls on the top right something about boot certification then it disappears and i get a black backlit screen and can do nothing

You need to go back to stock. Try entering download mode and flash kdz. .. Look at the sticky at the top of this forum.

Hi,
To enter in download mode:
Turn off device PRESS VOL UP while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead

Thats not a bricked phone!
Before flashing and getting into rooting your phone and flashing a recovery, I suggest you to read about it.

Boot Certification Verify?

Hi guys, need some help deperately please.
I've got an LG G2 D802 that has received the OTA update to 4.4 and is running fine.
I've since rooted it and i was looking at installing a custom recovery before flashing a new Rom......
I have tried to use Flashify after downloading TWRP recovery through Flashify but after rebooting it comes up with the following in the top left of a black screen;
Error: Boot Certification Verify
810 - secure booting error
860 - cause: boot certification verify
Then the screen goes off, ive left the phone and tried to reboot by just holding down the power button for 10 seconds but on boot i just get the same message then it dissapears and i get a black screen again
Any help or pointers would be great - thanks in advance
Try going to download mode and flash your kdz.

Thankyou for the reply - Any chance you could link or give me a quick tutorial on how to do this please?
I've connected the lg g2 up to my pc via usb and held down volume up and power to get into download mode - i get the screen on the lg with 'Firmware Update' on it and a bar with 0% on it and writing that says "DO not unplug the USB connection until the process is complete.
I've located the kdz for my particular device/model and downloaded it on my pc - how do i flash to my phone from here please - simple step by step instructions would be great thanks!
Of course. Please read this thread and if any troubles occure write here
P.S. disable Antivirus before proceeding.

Have done!
Well ive tried to root again using ioroot 25 like i did initially but my phone doesnt like it at all
I get the little green android with the spinning thing on him but it doesnt go any further than that when i run the Windows Batch File - so going to do the whole process again - frustrating to say the least :/

If you've just flashed the KDZ, do a factory reset instead of just booting to android. (hold volume down + power until you see the lg logo, release for a moment and continue holding the 2 buttons untill the factory reset appears). If you're on the new base with knock on and the ioroot issues the reboot to recovery command it has the same effect, your data is cleared. You have to retry the rooting process (the second time it should work).

I've finally sorted it out now - on the first flash of the kdz my phone pretty much remained the same, it bought it back to life and it wasnt reset at all and i couldnt root it.
On the second flash of the kdz my phone went through the whole set up process again (enter google account, language etc) and i managed to root easily after that.
It's put me off installing a custom recovery now though Ive expereince with the htc one x, dell streak, zte blade ...... all fine but with this im worried about getting a recovery installed incase i mess up again!
I know there is TWRP recovery and Philz recovery available but using flashify was what got me into this mess - do you suggest i use the usb cable and connect to my pc and install a recovery that way?
Side note - ive downloaded TWRP and Phils recoveries but none of them have a Windows Batch File to run hence me using Flashify - ive put the question on both of those threads aswell - where is the BAT command to run?
Thanks for your help
Use autorec m8. First root, second download autorec and click flash. Done

i turn on my LG Li-ion and it just keeps saying boot certification verify

Stuck in fastboot!!! (Sprint G2)

So I think I screwed up big time. I rooted my phone, found the AutoRec tutorial and app and installed and ran it, once it tried to reboot into recovery it immediately went into fastboot saying
"[5360] Fastboot mode started"
"[5410] udc_start()"
No matter what I try to do i won't leave this screen (other than powering it off), I've tried flashing two different twrp recoveries too.
Please help I'm stressing out big time
Update: I've gotten it out of fastboot, now it's stuck on the LG screen (since I wiped it clean)

tried this and also tried fastboot commands for twrp, and it says booting or flashing failed dtb not found
Then probably remove battery for few minutes and then try again, i am not sure if this would help.
