[Q] D855 Hard Bricked :( - G3 Q&A, Help & Troubleshooting

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

Hard Bricked D850PR

So the story goes as this:
ATT G3 accidentally flashed a D851 rom... phone rebooted now its a hard brick
I have tried every method to restore it to stock (lg flashtool 2014 and old flash tool method, tried enter TWRP nothing happened)
My phone is detected as it were in Download mode, but it doesnt let me flash anything.
I downloaded the "generic" LGUP8794.dll and tried to flash stock D850 and stock D851, jeez I even tried to flash LS990 stock rom... same error every time.
Downloaded stock D850PR20A_01.kdz and tried to flash it through Flashtool 2014 and just getting error...
I'm really out of options now.
I dont have warranty so its out of question the "return my phone" thing.
Thanks in advance for any reply or suggestion.
PD: I get no "QHUSB" or "fastboot" mode either.
Try using a different usb port. LG flash tool hates USB 3.0 so use USB 2.0

I have tried with 3 different computers, one with XP, Win7 and win8.1
I never use USB3.0 unless its with a memory stick
Can you go into download mode??

No, No Download mode, but my phone is connected as it were in download mode.
My screen is good, I know cuz when i connect the usb without battery it lights up and shows an image of "missing batt"
No TWRP either
Any update on this? I just rooted my D850PR and then used AutoREC to install TWRP, then I turned it off to reboot but it never booted...it also lights up the display when connecting the USB cable without the battery but that's all it does

i cant believe there is no clear solution for the LG G3 brick.
There is a solution
I have faced this issue with my LS990. accidentally flashed D855 ROM then bricked. THere is a unbricking method which is very hard and you have to do it with patience.
Try this
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
You might want to short 2 pins of G3 motherboard. message me if this method didn't work.
Good luck matehttp://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
I had that problem, flashed d855 rom on a d850pr, and it went into bootloop, but I just went into recovery, flashed a D850 rom and everything worked fine. I did have your problem once, but with a LG Optimus L2, I tried on windows 8 and 7 but the LGflashtool always stop with errors, until I tried on XP, i could restore it. (sorry for the english)

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 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

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

Success after supersu bootlooping and non recognized usb on g4

Like a lot of people I have the eu version of the h815 and managed to bootloop it after following the garbage methods online for rooting .. I came here for help and found all the methods listed... lg up, lg flashtool 2014 etc.. the problem was that my phone just wasn't recognized by the computer, it charged well but that was it, lg bridge, lg up, lg flashtool.. none could find my phone.. I thought I was doomed to a soft bricked paperweight and even began contemplating the hundreds of pounds needed to purchase a new phone.. however after hours and hours of tinkering I cracked it and now have a working lg g4 again.
first off download and install lg up dll file
then install lg up but don't open yet
find and make sure u download the correct kdz firmware file ( I needed the h81520d file which I downloaded from storage cow as devtesters didn't work for me)
now head to your computer control panel and delete(uninstall) any lg mobile drivers that you see.
connect your phone through usb into download mode and leave connected
once that's done download the old drivers (4.0.4 I believe) and not the newest 4.1.1 or whatever it is now.
then open lg up and hopefully like me you see your recognized phone.
click upgrade (not refurbish) and click bin.. right of bin is the ... symbol.
hit that, choose your kdz file and voila.. let it work its magic..
DAMN IM HAPPY. HOPE THIS CAN HELP SOME OF YOU LIKE IT DID ME.

Lg G4 H815 hard-bricked with different qualcomm soft?

Hello, (complete n00b here)
Several days ago I've tried to flash a 6.0 MM (from 5.1) to my LG G4 H815 phone. There was no option to do it automatically so I proceded to do it manually via flashboot.
I hard-bricked it to oblivion as in black screen, no response whatsoever.
While investigating @ the internet I've managed to understand I could get it fixed via quadcomm drivers (mode 9008).
Tried various "fixes" for H815 but was getting safari download errors. For some reason I tried a LS991 fix and it worked. When I started the phone it showed no logo but just a secure booting error 1006.
Still, could enter firmware download so I began to flash a lot of KDZ firmwares with no success.
LGUP shows my model : H81510H.
While in fastboot mode there is a note below (wasn't there the first time) with codes : 633 B46 or something like that.
While flashing anything it ALWAYS STOPS at 9% with a tot anti-rollback error. While flashing the code changes briefly where one can read smth like : LGLS991ZVA ver. 6.0
Managed to download some KDZ for that exact model, SAME ERROR. Tried to find / flash LS991ZVA with no success in finding a TOT file.
Also, managed to get ADB drivers up and it shows unauthorized in listing (LS991). Fastboot does not detect my device even in fastboot mode @ phone.
Please HELP!

H81510h is os version it is still at 5.1 I think....what may help is plug your phone in with lgup and drop the battery out of it then closes of LG up put battery back in and start LG up and find kdz that matchs your phone and make sure that it doesn't have anti rollback.....

Hello and thx for reply. I tried to do what u've said. It did something (I was looking for a while back). When I plug the cable back in, my windows 7 immediately installs quadcomm hs-usb driver (9008) and my phone acts as if it was dead. LGUP cannot find it in that state. I've been trying to QFIL the "proper" soft but it continues to pop different errors (using different QFIL versions). Either saharafail or some sort of download fail.
LGUP still presents an error (if I decide to "fastboot" it) @ 9% 0x2000, TOT antirollback version is smaller than device version.
How can I make sure I've got the proper KDZ without ANTI-ROLLBACK?

Thx again. Uppercut shows H81510H as LGUP did. Is it possible that it's somehow write-protected?
It confuses me, since during the firmware update on my phone, I get this small box below the picture showing wierd codes : 633A Bxx and when I'm trying to flash my phone, the code gets longer with LS991ZVA v6.0 and more other. It then stops.
Funny thing is, when I got the phone I couldn't even connect to the LG bridge to update it at all. I've managed to do it bugging the MTP protocol but THAT on the other hand prevented me from copying stuff / FLASH my phone to MM 6.0. Had to factory reset it back then and all went back to "normal" = LG couldnt detect my device but I could copy photos or stuff from it.
NOW, when my phone is bricked, LGbridge DETECTS my phone (in fastboot), downloads the newest KDZ update BUT cannot install it (same thing as in LGUP). Hence my question : is it somehow write-protected?

Have you tried to eset it by pushing power and volume own then when you see bootsplash then release power button and hen quickly push the power button again....
But in your case push power and volume down within the count or 20 then release power then push power button again and see what happens and then try the same thing on volume up......
Thanks for the reply.
I did what u've said. Despite no logo I tried to release power button for a second just after the screen's brightness goes up (I also get a small vibration @ start). Everytime I get secure booting error 1006 after a few seconds.
On the other hand when I did that with volume UP button there was no error but there was nothing aswell until I release power button in which case I got the secure booting error. All of the above tries were done with no USB connection with anything.

Do try with usb s well it may do something r do nothing......
Can't tell atm since I gave it to professionals. I'll wait and see how it'll turn up. Thx for all the effort tho, was nice to tinker with a lil help
@Longbranch did you solve this problem ? I'm in the same state but my phone model is H810, everything else is the same as yours.
Nope, not really. I gave it back to the reseller and my money got returned luckily.
The professionals I refer to above did install a specific firmware for the ls991 type. Firmware ZVB I think. The only one appliable apparently. Anyways, as I suspected the ls991 type is for the US and therefore it didn't work in my country in EU. My sim card wouldnt work with it. Besides, without the sim card, the phone decided to freeze and die after several minutes every time I turn it on. Swapped for LG G5 and it's working flawlessly up until this day.
good for you, what i don't understand is that it's a h810 model but now identify as ls991 does that mean you can convert it just by a Qfil flash? I may try another model flash if can't find a suitable Rom for it

Yes! That's what I and neutrondev telling everyone :
do not use qfil without the knowledge about the result!
The only working firehose file available out there is for the ls991 and that means if you use it it will turn your device into a ls991 without any way to get back to your previous device model!!
.
Sent from my LG-H815 using XDA Labs
@steadfasterX since I have done it already is there any way to get it working even as an LS991 ?
here is what i did till now
the reason for using Qfill is that it went dead after flashing an H810 rom .
after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

after that when it's in download mode it doesn't allow me to flash the ls911ZV5 ls911ZV6 ls911ZV6_12 roms that i found ( it says LS991ZVA )
so i went in fastboot and flashed boot/aboot/recovery....img extracted from the ls911ZV6 rom then it accepted the rom in download mode
but it is stuck in a hard bootloop ( reboots when it is getting in recovery but still has download mode yet no fastboot as before)
any thoughts ?

Yes it's possible. You can boot a h811 H815 or any other rom you like. Even LOS!!
Great right? BUT you are bounded to the ls991 modem and so you need to be in a sprint network to use telephony. That means the phone is now useless outside the US .
And you wrote you tried ls911 ROMs? I hope you meant ls991
I work on a fully working experience on every network though. Checkout my proof of concept for unlocking the bootloader thread
I can go into details on IRC if you like.

@steadfasterX thank you for keeping up with me ! ( btw what room on IRC ?)
for now I have used Qfill again and got fastboot working again and flashed TWRP ( not sure where ! ) so when the phone is off and i plug the usb it boots to twrp ( but it doesn't in recovery )
normal boot will show "secure boot error 1002"
then i flashed twrp img to recovery partition using twrp but it didn't work in recovery ( still reboots after showing Recovery Mode loading screen )
also tried to load some roms on the device to try them but I got error "file too large for filesystem " when copying them .
atm I don't know the state I'm in and what should be next ?
btw here are the recovery log and dmesg

Np we can bring you back to life but as already said without cell service. That's the price for the firehose and unlocked feeling you have now.
Did you found and read my thread here?
https://forum.xda-developers.com/g4/general/bl-unlock-unlock-bootloader-proof-t3648288
There you will find some more info and also the IRC details how you can find me. I'm online from Monday to Friday mainly.
It's much easier to talk in chat then here. once all the details are known I will provide a full guide.
