Are you sure you cannot get into download mode? Hole power til you see the LG logo twice, then release so it powes off completely... Then hold only Volume up and plug the phone into your computer while holding it.

What did you do or think you did to cause this? I would be easier to help if we knew what you were doing when this happened.

I had the same problem. Spent nearly 10 hours trying to figure it all out but never made any progress. I sent it to LG though and they are working on fixing it up right now.

i got an update after i installed it it didnt boot to system , went to recovery and after i restart it this happened . .
try plugging it in and use the LG software...I never done it myself but if you search i think there is a way you can fix it using LG software.

I am not sure if you this will help 100% but what I did was installed the recovery in my phone then I updated my phone. Which made my phone go in recovery and if I restarted it gets stuck in recovery. I wasn't able to get in download mode as well.
If you can get in "recovery" then you can use this fix
to get in recovery hold the vol- and power button until your phone vibrate and you are in recovery.
then execute these commands through adb shell
http://forum.xda-developers.com/showthread.php?t=2451696
Edit--- after executing the commands flash the stock rom--- using LG flashing kit. Search the xda and you will be able to find a thread that details how to do it. yes you will be able to get in download mode, i got there in 2 tries.

Sorry, can't read the link, but by recovery, you mean TWRP, right?
So basically, after rooting we can still do an OTA update, and it's still safe, right? But once we installed TWRP, we should not do any kind of OTA updates?
For TWRP, is this method good enough:

To Root, I will use this method:
http://www.youtube.com/watch?v=Y45SXPRb31o#t=149
Sorry if I am steering topic off-course but I just wanted to make sure others don't do the same mistakes and end up in same situation.
Your suggestion of not doing OTA update is really valuable, so I wanted to build on that.

The easiest and the way that really worked for me was to root it using "Vroot" http://www.mgyun.com/
but you should check which phone you have and which OTA version you have. As far as I know 11g and 11c for korean variant can only have cwm i am not sure if that is true for other phones as well. But be sure to check it. TWRP only works for 10x versions (where x is any alphabets) still dig deeper, I might be wrong.
But you should never update your phone after recovery.
and backup your IMEI number ... the thread i posted earlier try using google translate and download the apk to backup your IMEI by Hoang.

Will the phone boot normally so you can get to play store or it just won't boot at all? Are you using volume down and power, just making sure? Sometimes it can be finnicky like that.

ok i just tried it manually and the factory reset screen showed up, but when i pushed the power button twice the screen went black with the backlight on...
OK, try downloading quick boot from play store and TWRP from play store. Quick Boot will give you an option to reboot directly to recovery, try that first. Then, if that doesn't work, you can try running TWRP app and that allows you to flash a new recovery using the TWRP interface whole your phone is running. You may want to go to the TWRP website and download the most current version for your model first.
Edit: just use the TWRP app to install or reinstall the actual recovery you downloaded from the TWRP site linked below.

thank you i will try that now
The black screen with white lettering in the top left corner is the bootloader.
If you have adb you can download a new twrp recovery image and do a "fastboot flash recovery path_to_recovery\recovery_name.img" and then try rebooting into recovery. It should work fine.

That being said, you need to push a working recovery onto the device. If you can get into android, then you can access ADB from there and push the working recovery. You should be able to find the latest version of vzwG2 twrp in the g2 general section.
If you can't get into android, then you're ****ed as far as I'm aware. However, if this is the case then you can send it into LG and they will fix it right up for you

I've heard some people say that LG just reflashed the phone while they left root on there. I completely formatted the phone so there was nothing left on it before I sent mine in just in case.

You can't access ADB unless youre in android or a recovery, and you are in neither. You would usually be able to access fastboot (similar to ADB) which is another safety feature so you dont get bricked, but from what i've tried in this state i haven't been able to get into either.
You can try to play around with the android partitions in QHUSB_BULK and potentially fix it if you restore a recovery or something along those lines. But like I had said, I had no success with that.
Your best bet is to send it format the device and send it into LG so they can reflash everything.
Same issue, fixed it today
I had the same issues with a non-loading boot loader & a non-booting ROM. Follow the instructions in the thread linked below to restore stock firmware, and then root, TWRP, and install a custom ROM afterwards. The link to the LG Flash Tools was not one that worked for me, but a quick google search will get you the right file (top 3 results proved fruitful for me).

Well it's been a while since I broke a phone, so here I am!.... again
LS980. TWRP Rooted. Failed CM. Now stuck in boot loop.
I'm running Windows 7 64bit. I have latest LG drivers. Phone can boot into recovery but nothing else. I cannot boot into LG's "Download Mode". I can get into the "Hard Recovery Mode" which doesn't work anyway (Vol Up + Power). From recovery I can select to wipe cash and data and I can select to install from sdcard (no cards on this thing) or from ADB. When selecting ADB and trying to sideload stuff to it, it tries to load but always fails. If I try to push stuff it always comes back :closed
I cannot access any form of Fastboot. All i can do is let is loop or enter recovery. Since it seems to be the only thing I can access, can someone please assist me in what I should be trying to sideload that might get me a step further? I cannot fastboot so anything there isn't an option. Seemingly all I can try to do is sideload something. What... I'm not really sure. And no :crying: I don't have a backup.

You were right, I was doing it wrong. Once I got into download mode it went easy.
Response to others, I found that if I held vol down by itself long enough, the phone would stop bootlooping and shut off. I could then properly go into download mode.

1. Hold the power button until the device is OFF.
2. Download LG drivers to the PC (LG VZW_United_WHQL_v2.11.1) and LG mobile support tool (B2CAppSetup).
3. Install these packages.
4. Plug in you USB cable into the phone but not the computer.
5. Hold volume up and insert the USB cable to the PC- the phone should boot to 'download mode'.
6. Open the support tool and click Options>Upgrade Recovery, follow the prompts.
7. At the first prompt indentify your phone using IMEI/ESN, then click OK
8. Let it do its thing, the phone will reboot and most likely have a bunch of error messages and some FC's. Just hit okay to all messages, the phone will settle after 2 minutes or so.
9. Download freegee from market and reflash recovery of your choice.
10. Make sure you have a ROM saved to the SD to flash
11. Use freegee to reboot to recovery
12. Once in recovery you can reflash the ROM as normal.
13. Reboot and Profit!
*$* Or you could go back to Stock and start fresh!
*$* BEFORE ANY FLASH ALWAYS STOP and MAKE A NANDROID BACKUP!
Good Luck and if you get stuck let me know
Similar issue
I'm stuck in bootloop, no custom recovery or root. All data has been deleted. I have tried the LG support tool, but it locks up. It also tells me my device is a test model, something bad has happened. I can get into download mode but can't flash stock, via the flash tool. It says wrong device, and at the download screen where my phone says rooted it says the model is a D802! Somehow this info got jacked up! I can almost make it through the D802 flash but it fails also. I only did that to confirm my suspicion that the phone thinks its a different model. I'm open to anything, I've tried it all.

How was this resolved?
Hi!
I managed to get my device totally bricked.
Phone is on bootloop and I only get LG logo and then "Security Error" message. I can't enter recovery mode or download mode. Only mode I'm able to go is the "Hardware key control mode" mode, where I can see my IMEI code. I can't get windows or linux to recognize my phone. I've tried several drivers, but no luck getting my laptop recognize my phone. I have also tried couple of tutorials to solve this problem, but the main problem seems to be that I can't get my laptop to recognize my phone.
Is there anything I could do or should I just buy a new phone?
Hi Jutei,
What led to this bricking? Were you trying to install a ROM? Which ROM was it? Was it a wrong variant? Please be specific as to what you did to brick it..
Also, some people have seen success by installing this driver. Are you familiar with ADB?

Hi deathbytalkshow!
I ended up to this stage by rooting with this (http://forum.xda-developers.com/showthread.php?t=2448887) and trying to flash with this (http://forum.xda-developers.com/lg-g2/development-d802/rom-xenonhd-d802-t3036576).
First I wiped data and cache. Then rooted and it went trough with no problems. I tried to flash with this https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager. It booted to recovery and started flashing. Soon it said that flashing failed and after reboot I found myself in this bootloop.
Hope this helps someone to help me.
Try this:
1. Turn phone off.
2. Press POWER+VOL DOWN
3. When LG Logo appears, immediately release POWER+VOL and press and hold VOL UP+VOL DOWN

Hi, I tried this and got to the factory reset window. It started to do reset, but pretty soon it booted and went back to bootloop. So this didn't help. I'll try those ADB drivers today.
Hi, tried adb drivers, but no luck. My laptop still doesn't recognize my phone. USB gives power, but beside that windows doesn't seems to notice that my device is plugged. Is there anything else I could try?
so you didnt make a backup before flashing? what recovery did you flash? i bricked my phone with rom manager before and will never use it again but i had a backup and was still able to get it to eventually boot into twrp to restore.

also if you never turned on usb debugging i dont think you can get a computer to see it unless its fully booted.

Yeah, I was stupid enough not to backup. The recovery was the stock one. Is that where I went wrong? Should I've had custom recovery installed?

I turned usb-debugging was on before phone got bricked. I think the phone should be found somehow on computer. For example this fix (http://forum.xda-developers.com/showthread.php?p=48765620#post48765620) needs Linux to recognize the phone, but I can't even do that. I guess the problem here is that my phone won't enter the download mode. I'm going to try with couple of different computers when I get back home from my holidays.
I also found another fix to try. I have to drain the battery and after a little re-charge I should be able to enter the download mode. I'm trying this next.
yes thats where you made your mistake. that also makes me think download mode wont work period, but im not positive. im surprised rom manager even tried to flash anything without a recovery. thats why i dont use apps like that anymore because you wouldnt of been able to **** it up that bad on your own. so you said you tried the key combo to take you to the factory restore? if you didnt flash a recovery then i would think you could get that to work. did you look into lg's flash tool? maybe that will somehow read it. i remember seeing a post in the general forum about a way to take the phone apart and short the chip out but ive never had to actually read it so i couldnt tell you whats all involved. sorry bout your phone.

Well, I just got myself in the same boat.
The phone will show the LG Logo then the security error and shut down. When plugged in with a USB to the PC it will just reboot.
Nothing is showing in Device Manager either. I done the same in the stock recovery and I tried to Side load CM12 it failed and straight into this loop.
I got nothing now. I just done see how shorting circuits will fix the issue when it's just software. Absolute nightmare as the 12 months warranty has gone.
I tried to do a hard reset and I get the android man saying its working then it shuts down and starts the error again. I'm unable to get in the Download Mode either and I'm stuck
I don't know what to do now. The flash and Support tool will not recognize the phone.
jfletch86, I tried LG Flash Tool, but the problem is that it just says no devices found. Same problem with fix I linked, I can't do anything to my phone if my laptop doesn't find it. I'm beginnig to loose hope

Oh man, I'm sorry to hear that you are in the same boat. Symptoms are the same. It seems that we have bricked our phones pretty badly. Hopefully someone comes up with fix that works. Problem is that anyone wise enough to fix this isn't stupid enough to end up this stage.
I'm hoping the same too. I just don't know why it wont allow me to do anything.
I have a nexus 4 and I've never had a problem.
I am getting nothing when plugged into my PC and its like the phone is turning on and off in the boot loop and the lg symbol.
I get the hard reset menu but the computer still doesn't recognise.
I just feel sick at the moment !!

Just remove the battery, put it back again and go into recovery mode (twrp). And do a clean flash again. If it doesnt work, then just flash another rom. Put the rom inside the sd card and flash it via twrp

When you put the battery back., do you press and hold down volume down and power button and then whe I the logo appears you rapidly release and press and hold the power button without removing the finger from the volume down?
Its all about timing to be honest. Took me about 10 tries before I noticed I was being stupid. Right before the corrupted screen shows up, there is a very small window that you have to do this at. What I do is this.
I hold the volume down button while it is fully powered off.
The I press the power button and as soon as I see the LG Logo (It pops up for a split second before the corrupt screen) I let go of the power button and then press it imminently after I let go of it and TWRP shows up in a few seconds.
Again, its all about timing.

Did you install the H918 Rom or the US996 Rom?? If you didnt flash the TMO rom then you might be SOL. And it seems that whatever happened crashed TWRP as well... Are you able to get adb to detect the device?

To be honest, im the least qualified to try to help! It just stays at the lg logo the entire time? No static screen or anything? And TWRP crashes no matter what? If you can get it into download mode you could try to restore jt using a KDZ for your model?
https://drive.google.com/drive/mobile/folders/0B6Wj13Rw1kw-QTViRFJRaVRHQnM?usp=drive_web
You could try LGUP to see if you can restore it. Just make sure its the right model..

you could try to push TWRP into the system by using adb, just in case it has become corrupted. Then, if that is the issue then that should fix it.

Try this to go into fastboot mode : http://www.hardreset.info/devices/lg/lg-v20/fastboot-mode/
pull battery out put back in. Hold volume down, plug in USB to get into fastboot

Weta is amazing, just use the one for your phone! Or it wont function. If you have the tmobile model then only use the tmobile rom xD Just make a backup in TWRP before flashing so you dont have to start completely over.
