Hi XDA
i didn't want to make it a long thread but i have to , bare with me here :
first i followed that topic on XDA : http://forum.xda-developers.com/lg-g3/general/guide-update-to-lollipop-root-bumpd-twrp-t3048845
i tried to install twrp with imageprep but after rebooting it says secure booting error or something like that
i also tried this after that but with the same error https://www.youtube.com/watch?v=2we1YDc5JGU
but always the mobile was rebooting and opened like nothing happened
so i searched the internet for a solution i tried this one : https://www.youtube.com/watch?v=4YZ0i6aFsfM
but i guess the file attached weren't compatible so it ends up with an error before doing anything so there was no option except this : http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977
and here comes the misery , cuz i just got my phone and after the step while you write the commands in the android terminal emulator
and BOOM everything went black
NO BOOT , NO RECOVERY , NO DOWNLOAD MODE , absolutely NOTHING :crying: i freaked out a lot , but after searching for 3 days i've found this xda thread : http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
sadly i'm now on LGE AndroidNet USB port (com 11)
and what i'm getting from this thread that i've to short circuit two pins in my LG G3 Motherboard so i can switch LGE AndriodNet USB Port to Qualcomm 9008
Before anything else i want to make sure that i'm on the right track so just want to approve these steps :
1- open the phone
2- to make the device read as "Qualcomm 9008" not as "LGE AndriodNet USB Modem" i have to :
a- short cut the pins in the photo you provided "without the battery" for 3 minutes
b- connect the phone with the USB cable in the computer "without the battery"
c- my PC will detect the device as "Qualcomm"
3- after that i'm good to use your LG G3 unbrick method
are these steps right ?
just need to know when to plug in my battery and when i connect the phone with the cable , the pins must be connected or i can just connect the pins for 3 minutes and then remove the connection between them ?
Please anyone answers me with the exact steps or give me a short video on how to do it alone because i'm still rookie at these stuff
thanks xda members :fingers-crossed:

If you have asked for help in the threads you have linked, without receiving a response, you can try quoting someone that may know or use @ before their user name like @sd_shadow
This is a very technical and likely very few people have even attempted it, so it may be awhile before the right people log in to XDA and see your post.
This thread will be moved to G3 Q&A, Help & Troubleshooting

I too am having issues with my LG G3 trying this method but the thread linked has been closed.

Hi, i just solved this problem like just an hour before. And yes all your steps are right but make sure you select same port in the tool too,
And do not remove the connection between pins until your device recognize as Qualcomm

How long did it take for your computer to recognize the phone? I'm having trouble shorting the pins... Very small points that you have to hit. Also does the screen turn on or stay off when you do it correctly?

Maybe @os_man can help you with this error. i'm exactly not sure about this error.

is someone stuck at unknown USB device (something something) ??

I got past the error... Now I flashed the partitions. How do I get into download mode? Do I unplug the device? Do I need to plug in the battery for download mode?

here are the drivers http://www.androidbrick.com/?wpdmdl=3173 both 32 bit and 64 bit but remember that you have to turn off driver signing if using a 64 bit OS.
I'm back to the same thing that I had before just the lg logo and it keeps rebooting.

i am having the same problem since this morning.
Phone is bootlooping again and again. Cant enter recovery/download mode.
but some how just now managed to get into download mode, flashed stock kdz, it installed completely (100%), but again when it rebooted after the flash, same boot loops have started and am not able to get through.
this problem is really weird.
Any clue on how to check if i have a Qualcom port or LG port?

You have to force it into the qualcom port with the pin shorting guide

Again i stand corrected the g2 bad a ms dos script that pushed the partitions on the g3 wilzcracker aparntly pushes them so just follow the guide it works

Been a while since ive done g3. But if i ever hd or have any issues as such i just lgflash tool back stock and start over fresh. As said i havnt had a g3 in a while and i ditched my g4 cause of several issues ive been runnin a s6 for a while now. I have now idea where or what versions of firmware u need but it should be somewhere in your devices general section under something like return to stock or simmilar name

d855 stuck at boot screen after kdz MM flash

Hello guys,
I need your help on a problem. I've been away from Android development and I can not find a workaround for this. The problem is LG G3 d855 is stuck at boot screen and the led sensors lighting up. Here's what caused the problem:
Today I wanted to upgrade my phone to stock 6.0 to try. I installed a stock 6.0.kdz file by LG Flash Tool 2014. But somehow at installation it said can not connect to server, so I quit the application which I shouldn't have done so. I should've just sit and wait. Anyway, then I lost Download Mode and phone wasn't booting up at all. When I tried to boot up I got the error "boot verification Fail -cause MISMATCH_SIG_LEN". Somehow I managed LG Flash Tool 2014 to see my phone as Qualcomm device and started to install again (it took me briefly 3 hours if anyone ever face some problem or need help, I'll be posting a guide about it) the server error popped up again and I just ignored it and boy it was loading both on my phone and on my computer as well!
However, on the phone the process stopped at 4% and on pc it stopped at 13%. Then I got an error saying something like unexpected error. I tried retry countless times but it didn't work. So I had to say exit and quit the application but somehow, as I disconnected frustrated the phone started to boot, a little droid came up as if it came after each update then the normal screen.
I was quite happy because even the led started to beam up so I was hopeful it would start but however it's stuck now. I tried going into download mode and now I get "boot verification Fail -cause MISMATCH_SIG_LEN" error on there and it just restarts again.
I searched for hours and hours to find a workaround and I'm really desperate! I know if the screen boots up at least, it can not be so bad to fix. Please someone help me!

update:
somehow I can get my pc to see the device as qualcomm hs-usb qdloader 9008 (COM3) but BoardDiag now says "device was not found in dload trying flash programmer"
and still no answer from anyone.. I am still trying please someone help me out...

I already changed the port, but how to change to port 41? I tried 3 ports 13, 8 and 6.
If I connect the device to the PC and hold vol+ the error comes and then it should say something like software update.... but for me black screen appears and the led is red and blue. then I´m connected in qdloader 9008 too
