hard brick h811.... bdloader 9008 port need help - G4 Q&A, Help & Troubleshooting

ive read lots of tools and stuff for the g3 and nothing on the g4
long story short i was using lgflashtool on a g3.
and my g4 got plugged up to the pc on accident and it booted download and started flashing ls990 tot before i could abort
now i got no download mode, recovery etc

Have you tried using LG Bridge? I'd install it, plug your phone in and click Software Update then click "Update error recovery" in the bottom right corner and see if that can get it fixed. Other than that I honestly can't think of another way to fix it but maybe someone with more experience will be able to help.

Any news? same situation for me.

Yes, updates please.

[Q] PLEASE HELP! T-Mobile LG G3 Hard Bricked!

So today I tried flashing android 5.0 on my T-mobile LG G3 D851. I put it into download mode, started the flash and waited. My LG flash tool then crashed and closed. My phone was %6 through the installation however and was just left frozen after it crashed. I tried every way possible to restart it and get out of the screen while keeping it plugged in, but I couldn't...so I took out the battery and put it back in. Now nothing is turning on, I can't put it in download mode and the charging LED doesn't light up, etc. It's completely bricked....what do I do? I've already tried taking out the battery and waiting and plugging in the cord and then battery. Please help! I can't afford the insurance or another phone...
EDIT: Also the battery does have charge...although I don't know how long it will last.
EDIT 2: I just realized this flash was for the 855 variant..not 851. Does this mean that I am just screwed?
It means that you got expensive brick.
You cant enter into download mode or recovery?
Probably only help is jtag. Find someone who can do that.
Sounds like someone has learned a very expensive lesson! Have you tried to factory reset it?
Yeah JTAG is all you got if no download mode

The linked solution works only if the device shows some signs of life - atleast a boot logo.
i have a D851 that a friend bricked. She tried upgrading to Lollipop and flashed the AT&T baseband on this TMobile version. The result is a hard bricked device which does not even seem to power on. Shows no signs of life, except when connected to a windows pc. It shows up as 'LG Androidnet USB modem' in the device manager. No boot logo, recovery, or download mode. Fortunately she has IMEI and twrp backups for this phone (boot, efs1, efs2, radio, rpm, tz). I did some research on JTag solutions. Unfortunately, none of the boxes support the D851, yet.
Any ideas on how to recover this device would be greatly appreciated.

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
I am also facing this problem it's completely bricked when I connect device to computer it shows LGE ANDROIDNET SERIAL please help to solve this problem
On the computer or the phone

D855 bricked or hardware failure?

I have bricked my phone (don't know how ), or it's a hardware failure (maybe mmc), i tried to restore backup that i've restored a couple of times prior to today, and always was all ok, but not this time, twrp reported error during restore and had to pull out the battery to restart the phone and now can't enter to recovery or boot up the system
I tried with flash tool 2014 and didn't have success, keep getting message 'the phone disconnected from pc', drivers are installed correctly, but maybe my problem is that when i try to enter download mode after 4-5 seconds of download mode screen it transfers to fastboot mode started (no 'firmware update' screen). Tried with laf.img, recovery.img, boot.img via fastboot commands and keep getting messages
error : command never completed
error : auto CMD12 error
error : command completed with errors
error : command timeout error
failed to send stop command
failed writing block @ 1
Is there any method that I could try, or it's a dead hardware?
Highly recommend you take it in to a service center and get them to look at it. Just tell them that you were updating your phone from Kitkat to lollipop and that happened using the LG PC Suite
If you were restoring a backup of stock rom theres absolutely no proof whatsoever that you rooted it or you installed custom recovery and repair people cant be bothered going into fine detail just to check.
Essentially all your system partitions are blank except bootloader which is at least better than those who get QHUSB_DLOAD
Open teamveiwer i see error
Can not flash in fastboot>?
Hi,
Same problem here. Have you found a solution? Unfortunately, cannot flash in fastboot, because I always get the same error message:
error : auto CMD12 error
Can you help me please??

Can you help me unbrick it? I'm completely lost here I can't find my IMEI, the stickers were removed and also there isn't one on the phone itself. The phone is dead so I can't find it that way, but I'm trying to find the right kdz file :C

Remove the battery, put it, press the volume + and connect to PC USB, if like entering download, what
happens to us not to go, will leave the ****ing LoGo, Well, hold down the volume + and not let go, I
think it is less for 2 minutes more. After a while, the computer tells us that something was connected,
the phone will tell you who is in fastboot as I said before, if not let me fastboot flash boot files and
the LAF, recovery ect, nothing happens, there is still a magic command.
fastboot boot laf.img
Keep it in the ****ing heart

Help! I think I bricked my LG G3 and now I am in a boot loop!

I decided to downgrade my LG G3 D851 from Lollipop 5.0.1 to the stock firmware.
I followed all of the steps of to downgrade my LG G3 D851 to the tee.
Towards to end, you have to restart your phone at the blue screen, this is what I did by taking out my battery when the big red "3" came up. It looked like it worked fine in the video right? But, to my luck, it just created a boot loop that I cannot get out of.
The reasons that I cannot get out of this boot loop are:
1. Because the LG G3 is so messed up, my computer will only recognize it as an unknown device even with the drivers installed.
2. The only way as far as I can see right now to fix it would be to follow the steps of the SAME video that caused this.
Any solutions guys?
Sorry if I am being vague, I'm kind of new around these parts and to rooting. If you need any answers I can surely provide.
Thanks!
Okay see if you can cancan get ti download mode. Take out your battery, put it back in, then hold volume up and plug in the USB. You should see a firmware update screen. Once there use lg flash tool to flash back to stock via kdz or tot.

Hey! The reason that the boot loop was created in the first was BECAUSE I tried to flash back to stock. Also, even if I did try to do this, the PC would not recognize the device and would register it as an "unknown device" even if I have LG G3 drivers.
Do you mind sending a screen shot of what you see in the computer? Does your phone still go to download mode anyway?

Do you have access to a computer with windows 7 or possibly 8. From what I know WIndows 10 is not supported by lg drivers yet. This could have resulted in your brick, however you can try to uninstall the drivers and re install them.
should try running the lg suite on your win 10 machine in compatibility mode for an older windows

VS986 Hard Bricked

So my VS986 wont boot, light up or anything. No download mode either. Saw a tutorial on a fancy http://www.droidsavvy.com/unbrick-qualcomm-mobiles/ unbrick method however it didnt work. The only thing I can get is in device manager under Ports - Relink HS-USB QDLoader 9008 Com4. Sadly nothing came up under disk drives. I havent been able to really find anything on fixing it from this bad. Most threads fell off around a month ago with no more replies. Any ideas?
You might want to supply a little more info. How did it end up like this? What were you doing when it happened?

Well I was removing xposed so I could try and get Snapchat to work. That didnt go so well. Decided to flash back to factory. I think I may have selected the wrong kdz file using the LG Flash Tool via CSE Flash, but I cant confirm. ANy other info you would like to know? SOrry for lack of info, first time its happened this bad.
I can't remember will flashing the kdz wipe my rooted system img off my internal sd?

I hard bricked my phone while trying to root. Tried various steps but nothing helped.
Finally I did an RMA. Sent to LG. They loaded 13b and sent it back. The whole process took a week. No charge. They even covered shipping both ways.
If nothing works this is an option.
Why would you need to remove xposed to get snapchat to work? I have xposed with 2 snapchat modules downloaded and snapchat works fine.
I'm in a similar situation.I am using the Droidsavvy giude for the qualcom tool QFIL. I have gotten my phone to get the "Qualcomm HS-USB QDLoader 9008” MODE.
I need the "Flash.xml file " and the right rom type files to possibly restore my phone. can anyone help?
(nothing else will work I have tried all flash tools and still only the ( 9008 mode will come up)
Such a hard brick *might* happen if you downgrade. Or at least that's what I think happened, because although it's not often, the partition table does get changed every once in a while. And when it does, you can only move forward.

I have lg g4 ls991. mistakenly flashed a lower version firmware thinking it was the latest. the device is now hard bricked. no power, no download mode. luckily, I have extracted the firmware form the phone before bricking. I came across a few post where its possible to fix via sd card direct emmc. You will need to have SystemImage.bin file and win32Disk Image. I need someone to assist me on how to create the SystemImage.bin file. any help will be greatly appreciated!
