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.

So I flashed the latest nightly of Cyanogenmod and my phone rebooted mid flash and I can't boot into recovery or download mode but my computer still recognises the phone when I plug it in. Can I still unbrick it? And how? I have an LG G3 d855
Try it. http://forum.xda-developers.com/lg-g3/development/boot-verification-failed-secure-boot-t3337280
Figured it out
So I figured it out. As long as Windows recognizes the phone as QHSUSB__BULKfound its fixable. This super useful tutorial helps h t t p://open-freax.fr/guide-unbrick-your-lg-g3/
I don't know where to start. So I changed the resolution of my LG G3 F400L to 1080p via terminal. then I reboot it. The LG boot logo appear, after waiting for a while the logo won't go anywhere. the boot sound can be heard also when I touch the screen I can hear unlocking sound and touch feedback which means my device is working properly JUST the LG bootlogo covers up everything just like a curtain.
Another thing is, I tried to boot it to recovery to restore my firmware but it just won't work. My device has TWRP flashed by AutoRec. I used every button combination and tried like 100 times each that I found here: http://forum.xda-developers.com/lg-g3/help/f400l-recovery-t2960352 but the device won't boot to recovery. It just boots normally and stuck on LG bootlogo as I mentioned above.
Running to a dead end. I put my device to download mode (which the only mode that I'm able to do) to flash my device back to stock ROM using LG Flash Tool. After a few processes it stucks at S\W Upgrade part saying "Upgrade stopped due to an error". Just so you know I have the latest driver installed.
The stress and frustration really makes me want to bump my head to death. Any help and solution IS GREATLY APPRECIATED!
Please Help me.
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 know how to fix this

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

Background Information
So my G4 was hardbricked (won't turn on, no download mode, QUALCOMM 9008 when plugged into PC) because I was trying to return to stock after I had flashed a modified stock ROM on xda using the LG Flash Tool with the 13b(?) KDZ (this was around 2016) but I was recently able to fix it following the guide from gsm developers
However, upon turning on the phone there are some odd things that I've noticed:
It's really really slow, to the point where the only way to turn on/off the screen is to double tap it. Using the power button will make the phone hang resulting in having to pull out the battery to get it to turn on again.
The camera does not work
Upon booting the phone, on the top left side of the screen there is: "secure booting error! error code: 1006 OFFICIAL". From what I've read the other people's devices gets stuck here but for me it does not.
Unable to use LG Flash Tool or LG UP to flash 13b. (LG Flash doesn't detect phone neither does LG UP)
So all in all:
Where do I go from here?
What firmware is the most ideal if I want to root/unlock bootloader etc. (13b?)
Which flash tool do I use? (LG Flash Tool or LG UP)
Why is it running slow?
I really don't want to Hardbrick it again

I was able to figure it out. If anyone is going through the same thing, make sure that whenever you install new drivers, restart your computer, I plugged everything back in and LG UP was able to detect it and I was able to return to stock. The G4 is now unlocked running Lineage OS 15.1 with root. Just make sure to carefully follow instructions.
