LG G3 D855 (6SW) Bricked

My LG G3 kinda died in sleep. It powered off during the night and once I woke up, I tried to turn it off but it's now stuck on LG logo screen.
For a month now I've been going through other threads about this, but still can't find solution that works, I'm not sure if I missed anything.
Phone status:
- It won't boot further than LG logo screen
- From recovery mode, there is only 'Factory reset' option, which I've tried several times, but once again it gets stuck on LG logo
- I can go into Download mode but can't get it to work
So far I've tried with TOT files - LGFlashTool (version 1.5 and 1.8)
and KDZ - LGFlashTool 2014
With earlier versions (TOT files) I got message: Model check information FAIL! - Screenshot: i.imgur.com/N6sxbEt.jpg
And with LGFlashTool 2014 (KDZ) I got: Connection with server fail - Screenshot: imgur.com/wD6vWL3.jpg
While I'm not sure I'm using correct TOT files for my device (it's from Switzerland and has 6SW mark so I went with Europien files), I know that KDZ are good (I've used IMEI search option, so that's all good), but that doesn't even matter since it won't even comunicate with the damn server in the first place.
Any suggestions would be highly appreciated, I've lost all hope :/
Thanks,
Matt

hi bro.
try forcing phone to boot in qualcomm 9008.
and unbrick it with board diag.
for booting phone in 9008 mode you should open back of your phone.
google G3 test point)
on xda you can find few thread about unbrick.
if you couldn't repair it send it to LG Services for repair.

Question: Completely Dead Phone - What should I do ?

I have G3 D855 16G.
I was stuck on a bootlop and tried to install a kdz rom with Lg Flash tool. I succeded once then phone was bricked again. I used recovery with Imei from LG and failed to recover the software. Now when i try to flash a KDZ it stops at 4% and when I try to flash with Imei recovery it says that I dont have battery. Battery is charged 100% with an external charger. I tried also the .tot method and fails saying "model information check fail" even I have all correct files. Tried with Lg pc suite also, no luck. In Lg Up tool it says model unkown. The phone is not detected in adb but I have all drivers and appears in device manager. Phone does not boot up or in recovery or else. Sometimes i see led light blinking red after i remove the battery for a longer period of time and then try to turn it on. What else should I do ?

change your battery with an orginal one. then open back of phone and check te model written on right side of mother board. if it's not d855 then flash writed model's kdz

1.. Make sure you have really D855 model first.
2.. To use ToT method, your phone must be on" hs-usb qdloader 9008" mode.

If you can power on its 100 percent fixable. Bootloops are soft bricks not hard bricks. Make sure you have the right phone and the right kdz and use the LG flash tool or the kdz flasher from the factory. Go through the extensive thread in the help section. There is a large thread covering brick recovery and that's going to be more help than posting a new thread. Everyone will just direct you to the existing one. Good luck! I've done a lot of these brick recoveries and the thread in help section is great.

LG G3 D855 not booting after flashing

Hi. I've got a problem with my LG G3 D855 16gb, i flashed Android 6.0 kdz with Flashtool and it completed successfully but now it's stuck on blackscreen with green Android robot as shown in the picture. Any help ?

Does recovery boot and can you get back into download mode? You could try flashing again maybe the USB connection had a problem. It wouldn't be the first time that has happened during a flash.

I have just managed to repair my LG G3 D852 with a new motherboard replacement.
After i flashed it with LGUP using the LGD852AT-01-V10b-302-610-JUL-14-2014+0 tot file it will only boot into a screen with a spinning wired shape in the belly of a green robot.
there is a little bar on the bottom, but i have let this run for several hours without any change.
I can't get it into download mode and factory reset only results in the same problem.
I installed the Qualcomm HS-USB QDLoader 9008 to try and unbrick it, but my computer still dosen't recognize the device and that version number(9008) is not displayed in the driver list when i look at a list of drivers.
is there a quick fix for this?
most software packages for windows seem to raise problems with my anti-virus software complaining about some kind of virus or malware. something that works on linux would be nice, but i haven't seen any thing come up in my searches so far.
thanks

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.

Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

With flash tool goto device manager on pc.
click ports and com get into settings on it and change com port to 41
and have device in download mode powered off volume up + insert usb cord from pc

@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.

Thanks for your reply guys.
I manage to flash it with LGUP with a TOT that I downloaded.
Thanks.

Congrat @imider ,
maybe you can share what you did to fix your G4

Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.

LG G3 Qualcomm QDloader 9008 issues

Hello,
I have the D851 From T-Mobile and currently It has the boot logo then boots into qualcomm 9008 no matter if I try to go to download or recovery mode. I have tried the Boardiag tools and they have not worked for me at all. They all give the DLoad error. I have also tried to the LG flash tool but obviously that won't work. Anybody have any suggestions or any ideas to help get this thing back up and running?
