ok i see lots of threads about G2 stuck at LG logo with no download mode etc but none specific to my situation so figured id start my own.
my phone is stuck at the lg logo when i try to boot, when i try to go to download mode it shows the blue dots but windows, flash tool, nothing will recognize the phone as being plugged in, and not even the little sound windows makes when a usb device is plugged in, its been a little while so i cant remember EXACTLY what the last thing i did that bricked it was, something i did on command line with aboot something, i can try to dig it up if absolutely necessary but it would take some digging...when i try to boot into recovery it freezes at the "loading recovery screen, when i try to go to download mode it sticks at the blue dots and wont respond to anything, when i try to do a factory hard data reset it says "hard reset processing" or something similar then freezes there, ive tried reinstalling the drivers, using different pcs, read through countless threads, but have had no luck, any ideas what i can do to unbrick my brand new g2?? thanks in advance

This is what i would do....looks like your cable works, looks like you know how to get into Download and Recovery Mode. You have to get it to be detected, if it boots into Download mode it should work. Try re-installing the drivers.

Your download mode is broken. The laf partition needs fixed.
I'm looking for a way to do it from recovery.

with the phone off (completely), hold volume button (up i believe), and plug usb into computer. This should bring up download mode. If volume up doesnt work, try volume down. If you get just to the dots, then your download mode is broken.
was just about to start a new thread but didn't want to get into trouble..anyway I am in need of some assistance please.my ls980 has been bricked for some time now been searching all over the internet for a solution to be stuck back at square one.found this video on youtube which is pretty much exactly what my phone is doing.I have used lg flash tool to revert to stock and still nothing I lost root doing that but last night,I managed to regain root access I have no idea how but it happened when i clicked ioroot batch file i went into download mode and it stated bottom left ROOTED in red so i managed that but that is it still doing what is being shown in the video its on youtube
watch?v=PjLF-pBhZSY
please if anyone has the know how I would like to fix this phone rather then bin it thank you
Hello all,
Well, it's here... Unfortunately my phone got bricked last night
Can't boot into main screen and can't go to download mode anymore. The cause is, my phone was stuck when upgrading firmware and there's nothing to do about it except remove the battery, and then, BOOM!... "Secure Booting Error! Cause: boot certification verify"
Any LG G3 users here already experienced this problem?
I followed the solution on LG G2 sub-forum, but my ubuntu doesn't detect the port, although Windows recognized it.
If this happens to your G3 and you solved it, please share your experience
Thanks

If Windows recognizes it then try using LGflashtool again.

Not at all.
Finally, I claimed my warranty with LG, and the motherboard got replaced.
It's all working now
You could have unbricked it... I've done that twice already
im stuck in this, how?
I'm stuck at the same thing since yesterday.
could you tell us the solution @nofait?
I've been researching about this and noticed one thing,
if I hold the lg combo (vol up + usb cable), and keep holding it until it passes the secure boot error and the screen becomes black,
my device (d855) goes to the Qualcomm Download Mode (it's detected as ''Qualcomm HS-USB QDLoader 9008'' on windows 8.1 x64)
Apparently, on that mode we could use Qualcomm tools (QPST) to reflash the bootloader and the matching laf image (the one that brings up the download mode)
so we could then flash any KDZ using LG Flash Tool.
To do so we need to extract the bootloader files, sbl1.bin, aboot.bin, rpm.bin, tz.bin, boot.bin, and laf.bin, from a tot/kdz firmware converting them to mbn format.
Then using QPST eMMC Download Tool, we load the partition table xml and 2 image files: the flash programmer file and the qcom boot image, which I'm still trying to figure out where to get them since I can't dump my own phone, and then we might be able to recover it.
I'm still looking into it and hopefully we can find a way.
I did not send my phone to lg service, yet, because I think they will take too long to fix it.
It happened to me a few days ago, but i had TWRP fully working so i could simply flash a ROM and then recover my things.
That thing about windows recognizing it as a msm8474 was a drivers issue (al least for me), i have a S5 too, i think that when i was tryng to get Heimdall working it changed the drivers (as you may know, s5 and g3 have the same board), so i just simply uninstalled it and then reinstall everything using .exe files from LG's website, after that windows 8.1 recognize it perfectly and i could flash KDZ without problems.
Other experience i had and that may help is what happened to me using an LGOG, couldn't boot, no recovery, no nothing, just trying to turn it on, it managed to get in fastboot mode (but with screen off and red LED all the time),from that point it was just about typing commands and flashing img to get it working

Hi,
You'll need to use a Windows 7 machine and the proper LG USB Driver (first post of this message) and change it to the COM41.
Do a BOARD DL and when the screen comes up and tells you to not touch it, ignore and press OK. Then press the power button and at the same type touch the "Normal +power". It should reboot and everything should be fine
Cheers!

So,
Should I use windows 7 32 bit or is it fine with 64 bit?
Will I need a .TOT file and a DLL for my model ( D855P 16gb ) or can I use a KDZ file?
EDIT: ok so I tried it, but flash tool failed to get model information from the phone.
were you in download mode? I can't get to download mode here.

I send my phone to warranty service, where they changed all the motherboard with new IMEI and SN.
Hope that they don't ask for money to repair the phone.

Can you get into recovery or download mode?
nothing just black screen no led either but the computer recognizes the phone on devices settings it shows LGE androidnet usb serial port.
i tried every guide here on xda to unbrick and a few on other sites and noghting
the only thing i did not try yet is a tool called lg smart boot diagnosis tool that theres nowhere to download only an xda member seems to have this tool but im waiting to see if he can share the tool or no
I dont have much experience with lg yet but if there is a flashing tool for it since u can still get the computer to read you just the tool and stock rom reflash and startover
i tried that already the problem i got now is the phone cannot get to be on download mode lg flash tool gets me an error that can't change to dlmode. it seems im running out of options maybe i should send my phone to lg for repair but i rather not i would like to try a little more before doing that

To put it simply if you cannot get to download mode, at this time you are sol. Maybe in the future if we get the qualcomm files you could fix it if your pc recognizes in one way or another it is connected under ports. But right now as we stand we do not have the files to recover from your type of brick.
thanks for you reply it seems that im gonna have to send it to lg for repair i bought it second hand so t-mobile will not help me with this.
Can you get adb to recognize it? You might be able to extract the laf.img and use adb to flash it back to your phone. Then you'll have download mode back.
no adb either i tried that. i try all kdz methods,flash tool with tot file and modded dll it gets stuck on can"t change to download mode. thanks for asking
the only method i did no try yet is the lg smart boot diagnosis tool that a xda member has but dont wants to share the tool

This is true but two problems exist:
1) Correct me if this is wrong, if you brick your phone and don't automatically boot into fastboot mode there is no way to do it. You need to flash the full fledged laf.img so it is booted when you do the vol + plug in instead of booting to lg boot loader.
2) Even if his computer can recognize the phone what he has done probably makes it boot into QHSUSB mode and at this time we have no solution to fix it.
I have read somewhere on the g2 forum of fixing one of the types of QHSUSB bricks (they come in a couple of flavors) but I can't remember which one. I do remember he needed to flash the full fledged fastboot laf somehow then flash the aboot partition via fastboot. So if I was you I would do some digging in the g2 forums.
thanks everyone for trying to help.well i just send my phone back to lg for repair i will inform everyoneif lg repair my g3 or not thanks again

Can you get to download mode? Are All the adb drivers installed correctly?
USB OTG drives or cable are great life savers. I picked up a 32 gig USB flash otg drive from amazon. Works beautifully.

Hi,
I wanted to install the Linage ROM, so started the process of routing my tablet, which was running Oreo. I unlocked the bootloader and have installed TWRP 3.1.1-1. This is where my problems began. I did have USB debugging enabled but when I started the bootloader unlocking this facility seems to have been removed.
I now have a screen that says 'bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s' The tablet then hangs on the Google logo when it tries to boot up. If I connect the tablet to my mac via USB it goes back to
the 'bootloader is unlocked screen' So I wiped the tablet completely as I was unable to install anything via ADB, thinking I would be able to install via OTG, but the zips are not being detected in TWRP. The tablet also is not being detected when using fastboot. Does anyone have any idea how to get this tablet working again, or is it bricked? Thanks in advance for any guidance that can be given
You can always use the factory images from google.

Thanks for your assistance. Unfortunately I am unable to use ADB and TWRP is not seeing my zips when using OTG, so not sure if it will work. I'll try and put the factory image on my USB and see if it works. Anyone know why TWRP is not seeing the zips on my USB?
I have managed to get OTG working using TWRP and have installed the zip files, but when I reboot I get to the bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s' screen. Is there anyway around this , or am I going to have wipe and relock?

Look at the amount of storge it shows. Mine says zero. It appears we have to put a password in to TWRP for us to see the files before we can zip them.
