I'll be the first to admit I royally screwed myself here through lack of reading. I came here from the evo 4g lte after upgrading and decided it was time to root this phone. I had the zvc update. Here was my exact process:
1. used ioroot- successful
2. used flashify to flash twrp- unsuccessful (secure boot error)
3. flashed zv7-aboot.img through adb- phone gives up the ghost
So now my phone is stuck at the LG logo and the led that usually lights up when it is booting stays dark. I can get my phone into download mode but no further. Any and all help is welcome.
dont panic!
I think You have no other options except for flashing the stock firmware. Flashing the stock will unbrick your device.
Fix in the works

Yea, I just found this thread about reverting to stock. I'm gonna try the TOT method and see if that works because the 1st method doesn't agree with my computer.

Hello, I've spent about the past 5 days trying to figure this out. So, how this started was, a while back when I first got the phone, I wanted 4.4, so I rooted my phone, and tried to flashify a recovery like CWM and TWRP. Both of these failed. I tried many times, and no matter what I tried, flashing always failed. But guess what, my stock recovery was erased in the process. I forgot about it until today, where I found the OTA update to 4.4 was released, and attempted to do it. To my dismay, I forgot I had no recovery mode, and instantly got the "boot certification verify" error screen. Now All I can access is download mode, to my knowledge. So I've been trying to fix this, either by installing stock recovery, or another way to install a custom. All to no avail. When I use the lg flash tool for the stock recovery, it fails at "BIN CRC Check". Every.... Single.... Time. Despite downloading multiple replacement files. I would be perfectly content with installing a customer recovery, but the ways I see require the phone to be on, and use the built in recovery mode. At this point, my phone is bricked, and I am looking for any and all ways to either A) boot back up normally without installing a recovery and fix it later, or B) install a recovery, even if it's the hard way.
Update:
I followed this thread:
http://forum.xda-developers.com/showthread.php?t=2582142
It looked like it was going to work. I am using a Xubuntu virtual machine. I was copying the files over, and every time it finished copying a file, it unmounted and remounted my phone (I don't know if that was suppose to happen, just worth mentioning if it wasn't suppose to). I was super excited to do it. Hard rebooted my phone. And now it's just a blank screen. I have no logo, no error, and no download mode like I had before. Seriously need some help here.
Update#2:
I have the flash tool correctly working. Awesome! But..... I still have no download mode here.... So I can't use the tool....
Lastly, I am aware of the title.... i don't know how that happened. I intended to type "need", but somehow that happened. I do not know how to edit it.
Can you enter recovery?

Ouch bud you are hard bricked pretty much. It sounds to me from what you explained all the partitions are wiped clean. I don't think there is any recovery from that unless you have a nand programmer

Im confused you said you had download mode then didnt? If it works try using the alternate G2 dll named 8974, because the second time I used Flashtool only the alternate dll worked which is weird because just hours earlier I had used the original, the original said wrong model/download failed the second time.

Then use LG Flash Tool, the Verizon guide works for LS980. Except use LS980 dll, and you must use Verizon USB drivers (Not T-Mobile, ATT etc), or Flash Tool wont work.

Okay, so I'm having a bit of an identity crisis with my sprint lgls970 trying to flash the stock rom from this thread:
http://forum.xda-developers.com/showthread.php?t=2443185
My device is returning this error:
Check Phone Model = LG-E960
Check Dll Model = LS970
Model Name is different!
Check phone or DLL!
FAIL
The only thing that I could possible imagine is that when I flashed TWRP 2.6.3.0 to flash a custom kit-kat ROM somehow it tricked the bootloader into thinking it was the E960. Has anyone else encountered this issue? And could flashing an earlier version of TWRP possibly correct this? I have rooted, flashed, and went back to stock on a few different LG devices, but this one has me stumped.

The page you linked returns a 404 for me, looks like you linked a cached page that is only there for you.
Try this if you are not already.
http://forum.xda-developers.com/showthread.php?t=2536636
If you keep getting the error that you're using an E960, then try to flash a different recovery before flashing the rom. I don't believe a ROM would have changed your device, but an incorrect recover would.
EDIT: I see what you did, you copied and pasted the post in the thread instead of choosing edit then copying that and posting it in the right forum. No worries, just edit your posting here and change the link so others no what you're talking about. Still, if you have a reason for using that specific one let me know. Otherwise, try the one I linked. It can be flashed from recovery instead of download mode.

Let me try to find the orignal page. It was the one using the LG flash tool with stock image included. I have downloaded the files from the page you suggested but I want to use that as a last resort. I'm trying to stock/unroot the device since it's time for trade in. I believe That our assumptions about the recovery are correct and I'm going to try that first, but I'm going to change the link beforehand. I appreciate your help and I will let you know about the results.
LGFlashtool will show that and not work if you unlocked the bootloader.
You've got 2 options. LGNPST or flash the Rom dopy25 mentioned.

You shouldn't need that ROM I mentioned as a last resort. If you flash it and lock the boot loader it should work. Then you can unroot and it will be stock. Then do factory reset and it would be good to go. The LGNPST should have a full bin file that if you flash will return you to stock as well. Look in the unbricking thread that mentions soft brick. Here.
http://forum.xda-developers.com/showthread.php?t=2230106
Somewhere it says you can download the full bin instead of the teeny bin. Just read EVERYTHING.

So after getting frustrated and using LGNPST to flash a stock ZVC rom I was even more frustraded after soft-bricking the device. I decided to charge up my tablet and use that until I could figure out a solution. I noticed after plugging in the tablet it displayed a red X over the battery icon. So I figured that it might be the cord I was using. I switched out cords and flashed the stock ZVC with no issues. Problem solved, thanks to you all that have helped me through this thread.
Interesting. Even with the FlashTool showing that you're phone was an E960, just switching the cord solved the FAIL at 4 secs?
LGNPST worked great for me and it got me back to bone stock. However, I am now experiencing another issue upon flashing a ROM where it would get stuck on the stock recovery screen (black with blue letters on top). I can use the volume button to highlight the options, but the power button doesn't respond. So then I have to just power down the phone, put it into Download mode again and use LGNPST to flash it back to stock.
For those experiencing this issue here is the link to my post addressing this issue.

It sounds like you have stock recovery. Use the capacitive"menu" button to select.
You'll need to reroot/unlock to install other roms
Hi, I am new to the whole root/custom recovery scene so don't really know what I'm doing, so I tried to use Flashify to flash TWRP on to my international LG G3 running 5.0 (rooted). Unfortunately, when booting into recovery I got a small message in the corner saying Secure booting error! Cause: boot certification verify, before my phone screen went black and my led started flashing blue and red. Holding down the vol - button seemed to fix it and the phone still boots fine, but it does this every time I try to boot into recovery. I just want to play around with custom ROMs and TWRP
Anyone got a fix for this, or know what is going on (bearing in mind that I am a complete noob with this stuff)?
Thanks in advance

Are you sure it'll be safe, given my current situation? I was led to believe it was an error that I'd only be able to fix with a factory reset.

I have used this method and had no issues. The reason you can't flash it with flashify is because it only works on KitKat for lg g3. People using lollipop has to use image prep method. There should be two tutorials,one for going back to kitkat and one for alowing you to flash it while on lollipop.

OK, just had a read of the Imageprep post and this all seems completely beyond me. Is there an alternative method, or if not, could someone simplify what I'd need to do with Imageprep to get TWRP working on 5.0?

Hi all long time lurker in the forums made an account today just to make this post so here I go. I was doing the OTA update for lollipop at night and it was taking a really long time so I fell asleep. I woke up in the morning and found my phone to be stuck in a bootloop :crying: looking at various posts I figured a factory reset would be my best option but it didn't work in fact it made my phone worse....It stays on the LG boot up screen for a few minutes then goes to a black screen. I went back to looking at forums again and found a post about how flashing my phone would get it working again but problem is that my computer no longer recognizes my device and fails to connect. Another option I found was to use the system recovery mode and apply update from external sdcard but when I do this I get E: failed to mount /sdcard (Invalid argument). I've tried 2 sdcards and formatted them both multiple times but I still get the error. I'm not sure what to do and I am willing to try anything.

This is what you have to do.
1. Take the battery out
2. Put the battery back in (dont press power button)
3. Press vol up button and connect cable (without pressing power button)
This should lead you to download mode.
If you do get download mode then follow the procedure of LGFLASHTOOL and TOT back to stock
I suggest using ZV6 tot or ZV8 if you were already on LP.
Best of luck!
After flashing the device using the link (finally got it working) it does everything it needs to do but when it reboots on my phone screen is says Factory Reset Status then it has a giant 2 on the screen so I'm not sure where to go from here. In the flash tool at the end it says
Mini OS boot check....
Mini OS status=2
Fail to set mini OS status 3

I was on Lollipop 5.0.1, rooted with twrp. I wanted to return back to stock. I tried factory reset but it wouldnt work properly. Someone on xda suggested I use the TOT/KDZ method to return to stock. Both methods failed and I am stuck in DOWNLOAD mode. I tried getting back to TWRP and it goes to DOWNLOAD mode instead.
I did make a back up before this happened but I cant get back to TWRP. I used the guide here on XDA to return to stock. Please, I hope I didnt brick my G3. Im freaking out right now with no cellphone right now working.

Are you sure you did the TOT/KDZ method correctly? Because if you did it should overwrite all partitions and it should go back to normal
Download the D852 KDZ from here http://lg-phone-firmware.com/firmware-Lg+G3-Tutti-41.html and then flash it with LG Flashtool. Since your having problems its best if you use CSE flash since it will wipe everything and start new
