same here
try if you have warranty.. or try jtag box.. there isnt a way to fix this yet.. funnt thing on G2 shortening a circuit brings back to life..
there's no way to fix it? really o,O
I wrote a guide a few months ago for the Lg G3, isn't it possible to use it with the right DLlL and TOT/KDZ file?
https://open-freax.fr/guide-unbrick-your-lg-g3/
emmc chip is faulty or corrupt.
I fixed mine by heating up with hot air soldering gun until solder reflow.

Same here on my h811. I followed instruction almost exactly but missed 1 thing. It looks like there is no way to fix it by reflashing. Having soft bricked Samsung,Moto and LG g2 and finding ways to recover all of them,it was a shock that this happened to my g4. Androidbrick.com also mentions that we are out of luck.
Other people have sent it back and got it fixed. You can go to LG website to apply for repair. Did the same today and will update the outcome.
When I tried to reverse the sbl1 image, I saw some instruction about booting from mmc1 (I have no clue if it's from a usb stick or the sdcard)...
(since I have really ****ty skill, I had no success in reversing anything related to the bootchain, but I can still read clear string...)
I guess it should be possible to write a copy of the g4 system on it and then boot from it. Unless lg kept the code in their bootloader but patched it out.. (would be stupid tho...)

That's pretty much exactly how to fix the problem from what I seen from the people who are withholding information. I was able to get as far as make the phone turn on and Secure Boot Error 1006. I also at one point got it to detect as LGE Android NET device, unfortunately I didn't make a backup of the SD card before flashing another partition to try and go further. I also got the recovery to popup and attempt to restore default settings, but it just reboots into the 1006. I also created the entire G4 system partition table and everything from a US991 KDZ file and got the same SBE 1006 as I did with the LS991 dump.
I think perhaps LG is working with a universal unlocked boot loader on the SD card to bring up download mode and flash whatever stock firmware. They are for sure plugging into the SD card and then flashing via USB

If it can help I had the 9008 problem on my LG G4 H811. First there was no dump to do jtag , I found mmcblk0 files somewhere on xda , so I took a 32 gb SD card, flashed it with PrimaryGPT ( taken from extracted 10N H811 firmware) using win32diskimager and then I flashed each of the 50 first mmcblk0 to the SD card using dd command of Ubuntu, put the SD card into the phone and bam, phone is alive and it can entre download mode. I tried to flash a 10N firmware but the firmware goes to the SD card, I finally flashed a custom recovery, custom rom, the phone internal memory became the SD card, listing /dev/block folder does not show any trace of the emmc, so I think that my emmc is dead
bottom line, like you, I think that the solution is with the SD card method, the inspiration came from the optimus g pro boot repair with some creativity, but I think that something is missing .

YES! This is exactly what I wanted to test, even if the emmc is dead, your phone is still "fine." Use the sd slot and it will rise from the dead.

to do such thing, we need a database of phone dumps for now i need H815 partitions (mmcblk0)
yeah maybe we'll have more chance if we make a thread in the dev place.
it could help alot of people with bootloop problem..
I can fix these phones talk me on WhatsApp +918989874040

I have got a H818P bricked
Anyone can provide a solution on how to unbrick it? as this thread just provides H815 unbrick solution:crying:
:crying:
I had no luck at all with mine. Theres no indication the card is being read, phone just gets to boot screen then turns off again after 15-20 seconds then does nothing till the battery is taken out and left for a while. Then the same thing again.

Have you tried starting your phone in download mode?

Better still, I got it repaired under warranty.
Failed at downgrading before I knew it I was bricked so went ahead and used the Qualcomm method got it to show up in device manager. As I was setting everything up the battery fell out, now my device won't vibrate or boot for that matter. Beforehand it only vibrated when connecting a usb to it, Any tips bring it back to life?
(I heard you can boot the os from an SD card but I don't have the .img file for my device.)
Device: LG Verizon VS985 was running MM
bump?
With the d850 there is a trick to sort out the motherboard and get it to boot. If your battery is removable it sound with on yours. Try searching for unbricking. There should a tutorial on here.
1st- try the following method
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
2nd- you fail to unbrick or the following error occurs
>>>> EMMC test fail
this is due to dry soldering of EMMC chip
in such case use a HEAT GUN and give heat on the EMMC chip...
leave it for 30 minutes then insert battery and plug cable into phone while hold volume up key.
hope: it will be booted into download mode.
>>>> NOW install the stock tot & dll.
NOTE: DO NOT OVERHEAT THE MOTHER BOARD OTHERWISE IT WILL BE DEAD
i also had the same problem with my LG G3 (F400K)
i tried a lot but failed some time it was booted into download mode and failed to install tot & dll at 99% or sometimes 6%.
after removing and re connecting battery, it show QHSUSB DLOAD 9008 & never booted into download mode.
after 30 to 40 minutes it was being booted into download mode and so on.
i used a heat gun and NOW MY LG F400K IS WORKING FINE AND USING CUSTOM FULMICS ROM 6.6
Is it really emmc problem? I have the exact problem like you describe. Like hard to boot into download mode.
Even if it does it will fail at flashing using Lg flash tool.
Sometime boarddiag would give me emmc test fail. So, i have to re-short over and over again.
Also If i use different firmware like vs985, with just single attempt boom it boot into download mode.
Btw mine is D858HK
Hello,
I have a LG G3 D855 EUROPE. I can't flash any KDZ or TOT File, try with LG UP, LG Flash Tool, and LG Flash Tools 2014 and other.
On download mode, when flashing, the phone reboot and software lost connection to phone (when writing system).
The only way for me, is to reboot phone on Qualcomm HS-USB QDLoader 9008 and flash all partition with BoardDiag.
Writing all partition, even system and userdata. Then the phone can boot with KitKat stock rom. But when the phone boot correctly, the phone will reboot after 2 minute sometime, sometime 1 hours etc ... With green screen TZ Crash, or Black screen Kernel crash ... not always the same error.
BoardDiag emmc test report No error.
I think there is a hardware problem ? But how to debug ? Can it be only the connector charge ? Or is a motheboard problem ? (emmc or dram ?)
Is there a way to use SDCard for system ?
Thank you

Try formatting your LG G3
Power button + volume down (like when you go to TWRT recovery)and a dialog will appear "Factory reset" (or something like that).
Greetings.

Thx for reply. Already done. Wipe data do nothing. Kdz alway with error. Only boardiag can write image partition without error. But bootloop. I try to flash another tot file LGD855AT-00-V10b-HKG-16G (no europe) with boardiag. But after flashing, the phone have black screen, can't boot. Download mode and recovery is working fine.
I realy think there is a hardware problem
Battery give 3.7 Volts. When charge > 70%, the battery gave 3.8 Volts and the phone can boot with charger.
I think there is a problem with battery. With 2 amper charger, and a full charge 100%, i can boot the phone with charger plugins. I will order a new battery.

Yes change your battery(had the same problem with it).
You only want to flash KitKat or i doesn't matter?
Well here you can have Marshmallow one.

already try 30B (MM), 20A (Lollipop) and multiple 10 (kitkat) 10e 10f 10a. With LGUP, LG Flash Tool 1.8, LG Flashtool 2014.
ALL TOT, and KDZ give an error "lost connection" because phone is shuting down, or reboot (battery default) during process.
Only when phone is on Qualcomm HS-USB QDLoader 9008 i can fly partition with BoardDiag (because Qualcomm HS-USB QDLoader 9008 not using battery)
i have order a new battery
Hi all
It all happens after the screen was suddenly froze and having to take the battery out.
When turned on, the phone had a red/blue led problem.
It was first solved using the LGFlashTool V1.8.6.527 to flash in the LGF400LAT-00-V10a-LGU-KR-MAY-18-2014-0 tot. The phone was reverted to the original firmware and was functional.
Then I wished to upgrade to the latest stock fw (F400L30c_00_1217) using LG Tool 2014. Unfortunately this buggy program prompted connection to server failed and the text was messed up with ????? in the pop up LGUserCSTool window. It was force closed by the system so the whole process could not be completed. I pulled out the battery again(which I now think that I shouldn't do) and after restarting the download mode was ruined.
I tried to fix it using the short pin method here and if rescued would re-flash the tot using the LGFlashTool.
The problem is LGFlashTool did not allow me to do it this time with Model Information Check Fail just like others in this forum https://forum.xda-developers.com/lg-g3/help/model-information-check-fail-t3163715
Having received the message "Model Information" fail, I thought it was due to the firmware version mismatch so I decided to give the LG Tool 2014 a try, again.
I was learnt to ignore the connection fail message to let it run in the background.
However, this time it ended up at around 65% and now the download mode has gone.
Each time the power+vol up combination ends up being detected as qhsusb_bulk, a.k.a Qualcomm HS-USB QDLoader 9008
Not sure if the pins were physically damage during the shorting.
I have a thought. Is there any tool to convert kdz -> tot?
I know there is one to extract the bin, dz from kdz but I need tot to use in the boarddiag (as I think maybe the v30c firmware information has written into the phone by LG tool causing the LGFlashTool V1.8.6.527 to reject writing in)
What is the boarddiag for? Is it performing the same as adb/fastboot to erase/flash partition?
Or are there any workouts?
Thanks for reading and helping me.
it's so weird...yesterday it was stuck at qhsusb_bulk mode
so after placing for a day, it was detected as ABD interface today
and it was booted into fastboot mode.
I managed to erase partition but not flash..tried fastboot boot twrp.img
it restarted with a black screen and this time was detected as lge AndroidNet USB Serial Port
have tried the lg flashtool but no luck
Followed by that, I had applied the short pin method to restore the partitions again..
afterwards, i could manage to get in qhsusb_bulk only...
lets see if it could be in ABD interface tomorrow
btw, any ways to fix the download mode by the fastboot method given the bootloader was locked?
I was finally able to reflash using the tot file
but after flashing the phone reboots into black screen with flashing blue/red led just like previously(bricked status)
the phone was unable to connect as LGE AndroidNet USB Serial Port too
therefore, the flash tool could not complete
any idea for a fix?
my lg g3 f400s bricked

you need to heat your processor to open download mode
