Long story short, I tried flashing an older version of the firmware because I was having constant wifi issues even with a factory reset.
Everything went well, the phone rebooted with the android character on its back with the trunk open and the progress bar loaded until it froze. Now every times I try to boot it there's the droid on its back with the frozen loading bar.
Then when trying again to flash the stock rom using the COM41 LG flash tool, it keeps saying ''communication failed with device''
Here's everything I tried:
-De-installing and re-installing the LG drivers
-Tried the LG Flash tool method with 4 different computers and I still have the communication failed with device error
-The qualcom 9008 method where you need to short the ground with another pin
-Tried using LG's own tool from their websites to try updating or use the update recovery and it still gave the communication error
I can still boot it into download mode so there is still hope right?
Which is very annoying is that I still have 175$ to pay on it and LG's ''one price repair'' costs 150$...
Thanks in advance for your advices

By chance have you tried the stock reocvery or factory reset
Also you can try LG Up to see if it works The G5 threads some where has a modded version with refurb options
I was faced with a mjor hardware issue that would be flashed out stock with flash tool Had to use the refurb option with UP

I've found the LGUP tool on the G5 thread and I've unlocked the hidden features. Except I keep having the communication failed issue.
Both the LGUP and LG Flash tool make the same results it gets up to 6% says: ''LAF with a few numbers LAF 567.878.XXX as example'' then gives the failed to communicate with device

Looks like I'm pretty much in the same situation . I used to have a galaxy S4, every time I thought it was dead I would find a way to bring it back to life. Even my other G3 "D851 model from T-Mobile" which I did about the same manipulations in the same goal and didn't have any issues with it.

Yes! That's the worst thing! I can set it to COM PORT 41. Then when I start the Flashing with LG Flash Tool, the phone displays COM 41 in green and the complete name of the .tot file even appears of the screen of the phone!

If you used LGUP that definitely the reason your phone is in the state it's in. If i buy a cheap g3 off of somewhere and downgrade it I'll never use LGUP. lg flash tool is your best option though I'm getting a g6, cause the g3 is old now i think you should upgrade if an upgrade is your thing the i got some good phones on my list. But if you're gonna stick with the g3 then they sell 'em for pretty cheap and if you're gonna downgrade to 4.4.2 kk then use lg flash tool. If you're gonna downgrade to 5.0 or upgrade (not really) to 6.0 then use the modified lg flash tool 2014. All i gotta say is you're phone is done i learned it the hard way

Yeah :/ it'll teach me to stop wanting to crack every phone that falls in my hands. Just to bad I still owe money on it though. I doubt selling it on auction for parts on eBay would even be worth it.
I got the same problem with my LG G3 D852. I have tried multiple USB cables and USB ports. I can get into download mode easily, factory reset just returns to the same problem with a Droid open hatch and spinning wired shape and a bar on the bottom. I have tried LG flash tool and LGUP, but both fail at 6% with a communication error. I think the problem is my USB cable, but that is just my guess. I have followed the guides on the forms on this site, that is the only conclusion I can come up with.

Hello friendly devs,
So I messed up big time. I updated to 23C via the OTA and then discovered I couldn't do everything that I wanted, so I searched around a bunch for a way to put TWRP on it (never had it on this phone before) and of course no good way. I tried flashing it, and I got the fun certificate verify error trying to get into recovery. I could still boot normally at this point. I should have stopped.
Anyhow, I found a post about flashing the 12b aboot and that would let me throw TWRP on there w/o downgrading and losing all of my data. So, I tried it. Needless to say, this did not work. Now, I cannot do anything really.
If I try to boot normally, I see the certificate verify error with the initial LG splash, then screen goes blank. One red LED and then persistent blue LED until I pull the battery.
If I try to boot into download mode, I get the same thing (except the download mode symbol - which stays until I release volume button) and then screen blanks, LEDS, etc.
Sounds like from doing some looking that I'm basically up a creek w/o a paddle. I can maybe try to get into qualcomm mode (but I haven't found out how to do this), and try to follow these: http://forum.xda-developers.com/lg-g3/general/fix-unbrick-lg-g3-stuck-qualcomm-hs-usb-t2933853.
At this point, I'm thinking that's my only option. Does anyone have another idea, or at least advise on how to get my phone to recognize as 'Qualcomm HS-USB QDLoader 9008 mode'
Thanks for your help...

Thanks @jac10000, I appreciate your help! Unfortunately, that set of instructions didn't work for me. I get an error that says ''Model information check failed' when i try the security error section. I think it could be that my phone won't even show as an LG device. The best I can do is QDLOADER (and even that with special drivers, it plugged in as QSUSB_BULK), even though I had proper LG drivers installed (from previously using ADB...that's how I borked it originally). Do you know of any other things I can try? I've done many at this point and am starting to feel hopeless. Thank you again for trying to help me!
You need a different set of drivers I think. I had a big problem with the qhusb_bulk mode but after installing the drivers I linked on my post in this thread it read as Qualcomm 9008: http://forum.xda-developers.com/showthread.php?t=3072091.
Try it out and report back to us. You should be able to then run the boarddiag tool as per the instructions on the attached pictures of the op in this thread: http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091.
Follow all the instructions very carefully and you should be able to bring it out of a bricked state!!!

I was able to get it into Qualcomm 9008 state, so that's a positive. I tried some similar, but I guess slightly different instructions using board diag and wound up with 'Failed loading flash programmer' errors. I'll try these other directions tonight. maybe if they're more specific I'll have more luck.
thanks again!

I have somehow apparently screwed myself over worse. Before about half the time my computer was recognizing my phone when i plugged it in, and with the drivers, as the qualcomm 9008. But now, I can't even get that! I plug it in in download mode, or normal, or not on at all and the computer doesn't recognize it. I've tried uninstalling the drivers, reinstalling them, rebooting, not rebooting. I opened it up to try and short the test pin, as the instructions stated, but there was a metal covering over the qualcomm chip which I couldn't remove. I am starting to think I'm screwed. I have seen lots of people having success with d550 and d551, etc, but I'm worried the verizon model is different.
thanks again for helping me. If you have any other ideas, I'll try pretty much anything at this point!

I had my VS985 hard bricked when I used "DD" command to mess around to try to put TWRP on it. I tried every possible method out there and I found that they don't work on VS985. KDZ and TOT flash all failed, no ADB. I tried it for 2 weeks and I gave up and sent the phone back to LG for warranty service. Guess what? Even LG couldn't fix it. They had to replace the motherboard! I would advise you the same path. Since your phone is so screwed, LG probably won't be able to tell what you did to it. Just play dumb and say one day you wake up to a dead phone. It worked for me.
By the way, who told you to put a KK aboot to a L rom? That seems to be a sure way to hard brick your phone. OTA does not work with a modified phone (no root, no TWRP). When you get your phone back from LG, TOT it to 10b, Stomp root it, and install TWRP manager to install TWRP. Then you can find the Jasmine flashable zip to upgrade to L. Avoid all OTA stuff.

oh wow, huh. Was your bricked in the same way as mine, showing the 'secure booting error' when you try to start it up in any mode? That super good to know. I may just try. thanks for the advice!
Yeah, I will definitely follow your advice and do that, if I ever get it back! I followed a thread I found, but was clearly making a huge mistake. If only I knew that then!

When booting up, my phone did not show the LG and Verizon start up screen. Even the LED wouldn't light up. It vibrated once, so you know it was powered on. The screen was completely dark. When connecting to computer, the normal LGE device showed in Device manager and I could change the COM port to 41 for TOT flash. However, the flash would fail just like yours. The phone model, IMEI were all blank. KDZ errored out too. KDZ is more forgiving in mismatched phone model, and if even it fails, then you probably cannot save it.

Interesting. I appreciate the advice. I'll probably give it a try, since I seem to be out of other options, but I suspect the secure booting error will be a give away that i did something to violate my warranty.
Have been trying to unbrick my LG G3 D855 for the past 24h with no success.
First it was stuck on IIRC [710] Fastboot mode started and I was having problems flashing a new KDZ and using the .tot method, but after like 30 tries it suddenly worked just to get stuck in the factory 2 and now every time I try to use the LG Flash Tool I get the same error(Can't change to download mode, basically never goes after 6%). Also tried the Board DL instead of upgrade DL.
Tried with a different computers, different cables, different .tot files, different usb ports, different flash tool versions.
I really have no idea what to do now and I'm getting desperate.. Any help would be greatly appreciated.
Thanks in advance!
Looks like you did the same thing I did. You hardbricked it. Good luck but I think you need to get a replacement.

I had the same issue of the "dreaded red #2" and if you can get into download mode you may/should be able to fix it.
Search the forums again for instructions, verify you have all the settings correct and of course the correct files/drivers for you phone model. I believe you are suppossed to have the "BOARD DL" option selected.

I didn't had the same issue as you, but had a similiar one (phone didn't get discovered neither by LGUP nor LG Flash Tool). Yesterday I fixed it by following this guide:
http://forum.xda-developers.com/showthread.php?t=2785089
In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.
I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............
oh well
zach
ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(
I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.
Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.
One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).

i meant LGE mobile usb serial port (com7) and in portable devices its says LGE android MTP device and its has a yellow trangle
so does anything show up when you turn it on? how far does it get in booting? it goes to DL mode everytime? and that's what is in device manager in DL mode?

it boots into dl mode but i cant flash firmware yesterday i recorded it. it boots to lg logo and after 29 seconds it boot to the android guy i did find something in yellow text but it flickers and that says. in short
E: failed to mount /cache (no such file or directory) then can't mount /cache/recovery/log
can't open /cache/recovery/log
and it repeats that text 3 times from what i saw
did you install twrp? i would check your drivers or the cable for the communication failure in dl mode

My goal is to try and install TWRP my phone fully stock I checked everything even my charging port. I'm using the lg cable... My main goals are to get this fixed before March 3 and all I need is an alternative. Get TWRP or return back to stock
at least give me a script to boot to stock android recovery without adb. cause obviously i cant use adb and i hope anybody reading this can remember that with lg flash tool 2014 kdz method it goes to 4 and stops unless you guys find fix to that. all i need is to get this thing fixed before march 3rd. so if you guys help me find any kind of fix this is all i need
here is info but my phone
model: lg-d852 (don't really need it though)
status: stock unrooted device and has never booted into the system
android version: 4.4.2 kitkat
main problem that needs to be fixed: it cant mount cache cause apparently there is no file or directory according to my phone
that's it. if you guys need anymore info about my phone let me know (except imei or serial number cause that's all private stuff) thanks

I used every method
then you must force it into the 9008 mode using the following guide. I would check the dll you are using, drivers, or cable first through. I would be EXTREMELY SUPRISED of a g3 in DL mode that is non-responsive.

i'm surprised that my lg g3 in download mode with the correct dll, tot, kdz. every single program with a fully working charging port and an lg cable is that unresponsive. although at one point the arrows in download mode started spinning an then it stopped and on the monitor it said on lg flash tool (tot method). CAUTION: Primary gpt has invalid value there must be something blocking the connection
oh and my phone is still getting fixed soooooooooo no updates just yet. but like i said if there are no results i'll update you
Hello there pals, I have a problem, I have an Lg H815P (Mexico Version), and i was using it normally for about 15 days, then suddenly the home screen freezed, and then the phone restarted, i thougt it was just a lagging issue, but then, when the phone booted up again, after like 5 secs it freezed up again and restart, a infinte loop, then i said, this Rom must be corrupted (Stock TELCEL Rom v20b Android MM), and decided to do a hardware keys factory reset, then the phone restarted but when it was android upgrading apps, it kept restarting, at last it booted up but the problem persist. So im kinda worried, how a problem cant be fixed at a full hard reset? When im trying to flash a KDZ file From lg flash tool, the program fails because cant find phone, a kinda weird thing because the adb detects it sometimes, others not, i booted the phone in safe mode and the problem persist anyway, what can I do? I already have the drivers, the lg up, and the lg bridge apps, they all said that im running the last software for my mobile device, i´ve tried another battery as well, so im kinda lost, another thing, after the hard reset, the phone was able to stay on like 15 mins, sometimes 5, sometimes just secs, dunno what is happening but i really need some ideas, can you help me to work this out?
Greetings pals!

I have had this problem occur because of the launcher. Try cleaning the cache and data and see whether an updated version is available. You could also try a 3rd party one and see if that helps or simply re-install the LG launcher.
If no luck, you could try flashing another kdz with LGUP-NEW: https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
There are a couple of TCL kdz's listed on this site: https://lg-firmwares.com/lg-h815p-firmwares/
Scroll sown to LG H815P Firmware List.
Back up everything first.

Ty pal, I´ve tried with nova launcher, but no dice, still restarting, perhaps because i cant disable lg launcher from apps menu, actually i´ve been trying with flashtool and kdz files but i think the program doesnt recognize phone, cuz it show the message in lg mobile support tool: error required info cannot be found, contact administrator. I have the drivers, the pc in download mode and connected to pc, full charged, what else im missing?

Make sure you are using the correct LG Mobile Driver on your PC: LGMobileDriver_WHQL_Ver_4.2.0
If you are using the drivers your PC installs, you will have issues. Check in Device Manager on your PC.
Use LGUP-NEW to install a kdz.

I found the correct drivers and installed a DLL for lg up, so the program now detects my phone, the problem is that i install as Refurbish the same version that i was running, the h815p v20a, but when it finishes it says rebooting, but in the device is boot looped at lg logo and powered by android, the phne used to boot and show desktop, now is bootlooped, what else can I do to make him boot?
Cheers buddies

If the phone is still recognized on your PC, see if you can get into download mode. If you can, try re-installing the KDZ from there. Make double sure it is the same kdz that was installed on your phone when it worked.
The other option is to see if you can get into recovery mode and try a factory reset.
It is possible that the freezing you were experiencing before when it booted up was, as raptordd suggested above in post #4, an early sign of the hardware bootloop issue that has now manifested fully. The only real option then is to send it in to LG for repair and tell them your phone, you believe, has developed the hardware bootloop issue. Even if out of official warranty, they should replace the motherboard in that case, at no cost to you.

Now that u mention that, the phone was recognized by pc, but i installed a lot of kdzs, and none of them made the phone boot, every one of them were for h815p v20a, the one that was installed, but now i connect it to pc and then says download mode but doesnt enter and then the lg logo appears again, even the charge is meesed up now, i think i screwed the download mode and the charge mode, is that possible? but i tried the factory reset when i had the working firmware but the problem persists. Now im thinkin my only option is to use a octoplus box to revive it, but dunno if that will fix the restart problem, about that warranty stuff, i can send it to lg mexico and they should change my motherboard for free? That sound too good to be true.
Salute! pals

See if you can enter recovery using the hardware buttons and try executing it again.
LG has been replacing motherboards in a lot of cases where the issue is attributable to their own hardware issue (ILAPO). You don't really want to discuss the things you have done to get it working again with them ... if you get my drift, i.e., play dumb ...

Ok if none of the baove works, ill do that, but no, it has no recovery neither, not even stock, i read about a bootloader way to fix the download mode, im gonna try that but i doubt i can cuz bootloader is factory locked cuz is latin version.
No luck at all, phone is still bricked, is there any way to flash stuff via bootloader or abd without bootloader unlocked or root?
