[Q] D855 Hard Bricked :(

Hello All,
I made a horrible discovery as I went to set my alarm last night that my G3 has managed to hard brick itself. It wasn't rooted but had a few emulators and stuff on it and at some point it has ruined the phone
It has the dreaded QHSUSB_BULK whenever I try to flash it or use the LG Mobile Support tool after say 2-4%.
I'm hoping (praying) that some kind G3 owner (D855 16GB UK Model) could upload or send me a debrick.img for the SD?
If not I'll have to try and claim the warranty with LG as my return window has passed with amazon unfortunately.
First android and a month later a hard brick lol :/
Thank you!
(I know it's almost certain I'll have to send it away)

Are you trying the TOT flash method or the KDZ flash method?
Whenever i see a firmware flash fail it's almost always caused from a usb issue.
Try not to stress, i bricked my phone the other night and couldn't get it to flash for hours and couldn't figure out why, it turns out the 2014 PC i was trying to use wasn't having nothing to do with flashing my G3, but a 10 year old laptop got the job done without any hesitation.
Here's the guide i used to unbrick my phone, like i said other then the PC i was trying to use this worked perfect.
http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html
Here's a list of things you can try:
1. Try different usb ports on your PC, try using the usb ports on the back of your computer, they are the most reliable.
2. Try a differnt usb cable.
3. Make sure you have the correct driver, You should be using the LGUnitedMobileDriver
4. Try a different computer to flash all together.

If it is completly hard bricked try this => http://open-freax.fr/guide-unbrick-your-lg-g3/
I know there's one on xda too, but in my opinion this one is easier to follow and easier to understand.
If you'd like to check the xda one out too, here it is => http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359

The download is corrupted and other is off

you are right. use the lg flash tools 2014.
have you selected CSE flash?
are you using the correct KDZ for your cell?
what OS are you using?
have you installed the LG drivers?
what about the cable?
I personally do a hard reset before flashing a kdz.
I just updated my phone from LP to MM using the LG flash tool without a problem.

yeah. i am selecting CSE flash only.
I am using correc kdz .
My lappy is running on windows 10 and my phone is on kitkat v10n
The cable is 100% perfect as i flashed my g pro few days ago with the same laptop and same cable.
and coming to hard reset, I am unable to reset the phone. Just now I noticed that after selecting reset I went into black screen and can see "Fast boot mode" at the extreme top left of my phone. I switched it on and it booted back. What might be the problem.?

windows 10? I'd use windows 7 or 8.
your problem is not the flashtool. search for some tutorials about how to fix fast boot mode.

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.

I ran into the same problem and now i'm stuck in downloadmode!
Does this method work? Or is there any other fix yet?
Thanks in advance!

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.

i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.

i was lucky, i had flashed twrp before my phone soft brick..
Sent from my unlocked and rooted LG-H815

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!

Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english

D858 firmware installed by mistake on D855

I have installed incorrect firmware on my G3 D855.
After uploading the firmware for G3 D858 (Dual SIM) I don't seem to have any WiFi connection, nor SIM card can be connected. The biggest issue is, however, that the USB is not recognized anymore on my computer.
I have tried installing the latest LG drivers but this does not help. Download mode can be started, however, due to the USB issue phone does not appear in the device manager. I am afraid I have messed up the phone completely. Is there any possible idea how to recover to D855 firmware?
Thanks

LG G3 stopped working after installing recovery

Today I was trying to install a custom rom, but I messed it up and had to reset it to stock rom.
After that I reseted it back to stock rom, I rooted my phone with Kingroot and used this app: https://play.google.com/store/apps/details?id=b007.autorecd855 to install recovery. After that I powered off my phone and now it won't turn on. Already removed battery a plenty of times, when putting in the charger nothing happens, pc won't see it also.
The only moment when my phone lights up is when I remove my battery and put it in the charger, then it basically says that it's charging but with no battery in it. Also when removing the battery and connecting to my pc it only sees it as a unrecognizable device.
Suggestions on what I can do? IF not, poor me, gonna buy a new smartphone then.
Btw, I still have some garanty. Maybe it's worth sending it to the support services.

You used wrong autorec install LP recovery to MM. Download MM version autorec from LG G3 Xda forum. Try flash back to stock or something else. Instructions are in LG G3 Xda forum if you search more. Sorry.

Hmm, I was really sure that I used the right one.
Anyway, how can I flash it again if I can't even get the lg logo to show, neither get him in download mode or that my pc recognises him?
Btw, I still have some garanty. Maybe it's worth sending it to lg.

If you have no access to any recovery mode, Fastboot or download mode.then use the method of Qualcomm 9008.btw your warranty is void because you have rooted device and messed with it.

I also had same issue and I'm also sure that I used the correct Autorec version.
I sent the phone to LG because the warranty is still valid.

i remember after 1 day of having this phone this happened this was likely caused by having the latest boot loader i remember this because i fresh installed the marshmallow kdz after that i installed autorec mm it told me to restart and my phone died there, however after spending 8 hours straight i found a solution the smart boot diagnostics tool can write an older version of the boot loader understand that your phone must be in the qdloader9008 mode, if your PC doesn't detect the phone make sure you install the drivers in the zip from the download install the 32 bit if on 32 bit system or install 64 bit on 64 bit system. Hey if you need assistance on doing this Download team viewer and i'll be more than welcome to help unbrick our d855
