OK so my old G3 (lets call this one G31)has a broken digitizer, but I had another G3 (lets call it G32)and I just switched their motherboards after I flashed KK on LGUP while G32 was on MM. So the G32 was fully and wouldn't boot. Then I tried to wipe it through its stock recovery and now it always goes to the android with that thing through its chest. At the moment I didn't care so I put the G31 motherboard in the G32 shell and screen. Everything worked and still had my data. Then one day it fell and the motherboard snapped. So now I want to fix the G32 but it doesn't boot and anytime I try to flash anything it never goes past 6% on LGUP and says communication failure. It goes to download mode but doesn't boot. I believe I also flashed the wrong Kdz because the phone is LGD852 Rogers and I flashed a Bell Kdz. Any help would be appreciated.

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!
I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

Same problem here, but here the device is G3 Liger F490L.
Hey!
two days ago, out of the blue, by device restarted it self, and started to to it every few minutes.
after that, it just stuck in bootloop tho it was able to turn on for few minutes once or twice,
I tried to recover to factory settings from the phone, re flash the latest version with LG bridge, and use the flashing tool to reflash the kdz.
it always goes back to booploop(I think)
download mode works and not crushing.
any ideas? I

Unfortunately, the same thing's been happening to a lot of people lately. I'm getting bootloops on my G4 but it hasn't happened enough for it to be a problem. Once it becomes more of one, i'll send it in to LG under warranty. I would suggest you do the same too (LG warranty is 15 months from the month the phone was made - that info can found on the outside of the original box) Good luck!

So recently I had CM13 installed on my G3 D852, but I wanted to try out the Marshmallow port of stock without actually removing CM13, so stupid me had flashed MultiROM and the included TWRP that supports it. Anyway, after flashing the port my phone had rebooted to just the LG logo with the "boot certification verify" error, then the black screen with the blue/red LED flashing. I had tried to go back to stock but it kept failing, and now for some reason my computer can't even see that it is plugged in.
Am I basically SOL? I can get into download mode just fine but that's it.
Okay it's being picked up by my PC now but I noticed something interesting, the model under LG's Mobile Support Tool reads the phone as the D855, when it's the D852. I've tried the KDZ and TOT method of trying to flash back to stock Lollipop for the D852 and neither work.
How screwed am I?
Update: After countless hours of searching, I finally found a method that worked. My G3 is now back up and running.

Hello everyone,
I own a LG G3 D855 and recently I've bricked it. What I wanted to do was to flash official ROM (V30N) with LG Flash Tool 2014 back because I've had LineageOS and it had some bugs. Before Lineage OS there was V30N EUR and everything was working without problems.
The flashing process had problems, it was taking too long. It went to 4% in 30min and then it went to back to 3%. I knew there was no way it will finish so I've unplugged the device and tried to flash again but it didn't boot into Download Mode anymore. The device was turning on with a message: boot verification fail! cause: mismatch_sig_len.
To fix it I've followed this tutorial: https://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
But somehow my IMEI was gone so I fixed it using this tutorial: https://www.youtube.com/watch?v=y2lHFy7AciE&t=472s
(used the IMEI from the back of my phone)
So now this is the PROBLEM:
Everytime I flash V30N i get cust error at start. If I flash V30B global there are no problems with cust BUT:
No matter which one Im using my signal drops every time, especially when I turn my data ON or OFF. Sometimes the phone shows X on top of the signal bar and there is no service or it's endlessly searching for network. If I reboot it the signal is ok for a while.
Now what can I really do? Is there a way to rewrite EVERYTHING with a EUR TOT ROM? I'm downloading TOT files from here: http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
Thank you, any idea is highly apreciated.
Note: The SIM is OK.
Note2: I've flashed with BoardDiag V10e and V10a, same problem.
im having the same problem. hope you can help me when you find a way to fix this. Thanks!
So, some time ago I finally gave up on LG providing official nougat update for LG G4 so I decided to flash it and I found an official flash v29a, and everything went well.. except for my GPS. The GPS was not locking on and would take more than 100 seconds sometimes to lock on, I did not had this issue before so I decided to flash my device again hoping it would fix it, but it bricked my phone.
Now I can't reinstall or downgrade, since it would get stuck at 16% when flashing again and downgrade wont work at all. I get error 0x2000 "Invalid command Response". I have been trying to fix it for more than 6 hours now, downloading different KDZ's but it just won't work. I really need help here, I cannot afford a new phone right now. I have LG H818p version. And yes, I was using the correct version for upgrade/downgrade. I tried to hard reset it but it is still stuck on Firmware update. Urgent help is needed, since I don't have another phone to use and I really need this phone, been up all night trying to fix it..
Edit: Fixed it, don't know how tho
