LG G3 D855 Wont boot in Download mode.

Hi im new to XDA Developers Forum, i just tried this Solution( http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977 ) and my LG G3 D855. Is in the same state as from User "DonnieDoezoe"
"Totally bricked my phone with these instructions Won't turn on anymore. Tried everything...only shows a trinagle if I connect to usb without battery."
Before i tried this. I had already rooted the LG G3 D855, and after these instructions i tried to reboot into recoveryTWRP( wich i flashed with flashify) i tried to reboot with Quick Boot (Reboot ).
After this my Phone doesnt work anymore and is just like in the state of a blacksreen( the phone is visible as LGE AndroidNet USB Serial Port(COM41), the only thing that shows is a triangle if I connect to usb without battery.
I searched for solutions the whole day and tried to unbrick it with the LGFlashTool by flashing the .tot file and .dll, but wont work because i cant enter to the Download mode.
I Hope some one gives me hint in the right direction on how to fix this problem, would much appreciate it.

G3 wont stay in Download Mode

Hello,
the LG G3 D855 from a friend of mine got a black screen and wont boot anymore. If i boot it the download mode starts automatic but i cant stay in it because after a few seconds the sreen is black again and on my pc its only shown as qualcomm 9008. I tried to flash the ToT file partition for partition but that wont work. If i flashed one partition the phone disconnects from my pc and i have to remove the battery for about 3-4 minutes before i can access the mode again. Is there any chance to rescue the phone or is it maybe a hadware issue?

Hello everyone.
I have the exact same issue. LGFlashTool fails due to the phone exiting the firmware update mode during flashing and switches to Qualcomm 9008. As a result I have a brick because the phone got disconnected during flashing.
Then I have to use BoardDiag v2.99a to flash aboot, BackupGPT, boot, dbi, laf, PrimaryGPT, recovery, rpm, tz. Then I'm back to square one. I can use LGFlashTool, but the same thing happens again. Tried it several times, always the same result.
I know its a long shot, since its an old thread. "Last Activity: 11th September 2016 02:30 PM". But can someone please shed some light on this. Only thing I haven't tried is THIS since I don't want to break it even more, because I also read somewhere that you have to use BoardDiag to flash in the exact order mentioned above, and don't really know when does the system comes in.
Also thinking its a hardware or battery issue but cant really test it cause there aren't that many G3 batteries around since its an old phone.

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.

Hi,

thank you

help with LG G3 D855 very hard bricked

Hello
Yesterday I downgraded my phone from stock V30n to V30b, and then followed https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268 trying to root and install TWRP.
Rooting with kingroot went well, but AutorecMM looped endesly between "press button" and "flashing". Never rebooted or finished, just "press button" again.
I choose to reboot and from that point phone is totally dead. Doesn't boot in normal, download or recovery mode. Nothing ever on screen. No charge light. NOTHING detected in Windows 10 device manager. I know battery has some charge and also draws current from charger if connected.
My understanding after looking for G3 unbrick procedures is that bricked G3 should beep and be detected as something when conected to computer, even before the right driver is installed. Could someone confirm or deny this point?
Is there anything I can try before buying a new phone?
thanks!
Unbrink following a procedure like this, LG G3 is pretty much unbrickable.
