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.

Help, i installed the twrp recovery and went about installing a rom but when i went to wipe the phone i wiped everything. So now when i try to boot into recovery it just shows the lg logo with the l.e.d cycling. No idea what to do please help.
Can you get into download mode, If so you can flash the stock .kdz for your device with the lg flash tool and you will a stock functioning phone agin. Then you can root and install TWRP again if you would like just like you did the first time. But make SURE that you use CORRECT kdz for your device model remove the batteries and under you should she something like this eith the X being numbers or letters: LG-XXXXX find the .kdz for the XXXXX value and flash it with the lg flash tool
Thanks alot, its working but its taking its time still only at 14%

G3 boots into firmware update only
I recently updated my lg G3 ( Google patch update named Aug-18-2015 etc) and it started to malfunction with resets, crashing and eventually got it stuck in boot loop. Then it booted into a green screen that said "demigod crash handler/tz crash" thrice. Instead of a hard reset I decided to using the lg mobile support tool to fix it. During the upgrade recovery my phone went into download mode/firmware update. I could see the progress bar moving and then get stuck and my mobile would switch off. Took out the battery, disconnected and reconnected the phone and tried the process all over again but in vain. I repeated this at least 8 times and eventually gave up. Now my phone is basically useless and only boots into firmware update. Hard reset doesn't work either. Can somebody please help me fix this?
Android version : 5.0
Kernel: 3.4.0
Firmware : v20t-ame-xx
Go to the site: http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ and search for your device and message me back if it works

hey guys my G4 apparently bootlooped itself for some reason so i factory reset it which didnt help. This lead me to use lgup to flash the same MM that the phone was running from a .kdz file. Now after the flash it just stays on the LG bootimg screen and wasn't booting up. I removed the battery and put it on again and this time the phone shut off. I also have no recovery mode and when i attempt to boot into download mode it just stays at the icon and doesn't go to the firmware update screen so ive been doing some research and it says the bootloader is most likely the problem. My computer also recognizes it as the 'qhsusb_bulk' error but i came across no solution.
Can anyone give me some advice on what to do here...thanks in advance
Dear friends,
I am in deep trouble. Few days ago I have flashed CM rom on my LG G3 F400L. Now the problem is after waking up today I find my set totally dead. I can't enter into recovery mode with holding buttons. The phone stucked into LG logo. Tried many times to flash with LG flash tool. But it says download fail, device model is different.Check ur phone or dll. Tried generic dll but not working. Any help will be much appreciated. Thanks
yesterday after answering a call my LG G3 suddenly rebooted and since then it keeps rebooting after the "LG powered by Android" screen. I cant even go to recovery. I've searched and tried everything so far without success. My last attempt was restoring the phone using LG Flash tool 1.8.1.1023 (phone in download mode, TOT, DLL, COM41, etc) and everything gone OK, program reports "success at 559s" but it keeps rebooting on the same screen. any idea how to fix or the phone is dead? I was using LineageOS 20170515, TWRP 2.8.7 bumped/mod, pico GApps. It is the 32GB/3GB RAM unlocked model
flash D85530B_Global using flashtool2014 on download mode and see goodluck,if it doesn't fix it try changing the battery don't buy it just try one if it works then buy it
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.
