So i was unhappy with my rom so i tried flashing another rom on my lg g4 h815 which didn't work and i didn't seem to be able to install anything with twrp on my phone so i wanted to reinstall twrp which didn't work and now I have no recovery, and no rom on my phone and when i turn it on the lg logo appears and then i have a blackscreen, and then that repeats. the logo only appears for like half a second. when i try holding volume up and power the logo stays a bit longer, though my phone doesn't enter download mode. the LG bridge doesn't seem to recognize my phone even after installing driver, and the lg support tool gives me an error apparently but i can't read what it's saying, the error message is just blank. I'm grateful for any help i can get with this. thanks a lot in advance

I've tried to tune headphones output gain and at some moment phone stuck at boot.
Since then I can't reach recovery. The best I've got is the "download" mode.
"Ok, fine" – i said – "show me the fireworks!" and tried to flash the brick back to stock with LG Flash Tool 2014 and the downloaded KDZ-file. But recovery process always stops with unknown error at the point of 49%. I've tried restarting it several times.
Trying to boot phone shows updating android first, then screen changes to LG logo and that's all. It stays that state forever.
Any advice would be very appreciated.
still holding a brick... Help! :crying:
OK, I've solved it.

My LG G3 is and international D855 and is unable to enter recovery, with the phone going black after the twrp logo shows for a few seconds. The phone has no OS installed because I was going to flash a custom rom so there are only bootloops when booting up the phone. Entering download mode is not any good either because a message appears saying secure boot error and the phone goes black with only the LED flashing Red and Blue, I tried going back to stock with fastboot but in the process I lost the ability to enter fastboot, is there any hope
I'm hoping somebody can help and I would be extremely greatful, Cheers
If you can't access Download mode or fastboot mode.you have to do this as in thread.

My lg g3 is stuck on demigod kernel crash. i cant use any flashtool because download mode goes directly to 9008 mode.
i already used boarddiag by willcrack to one by one flash each files. including userdata with around 12gb lol. the whole process took about 10hours. but the same result. sometimes it will boot but it will constantly hangs. it goes bootloop sometimes. sometimes its stuck on lg logo without animation and no led. sometimes with led and sometimes will go to lg boot animation but still stuck. sometimes the status bar will appear with only time at 00:00 but the rest is black. im loosing options because even boarddiag flashes all the files fine but problem persist. i can access recovery. but factory reset does not help either
So I recently bought the Korean LG G3 (F400) and the first thing I did was rooting it, which was a breeze. Of course to root it I needed to install the LG Mobile Drivers, which I did and were working completely fine. Then I decided to take a little risk and attempt to flash CWM recovery (I did not know that I need to unlock the bootloader first or BUMP! the device) and well, flashed it the same way I flash stuff on my previous Samsung phones.
So now, when I try to boot the phone, I get the LG Logo and goes through with the boot animation, but after a little less than a second the boot animation fails and I get a black screen + the LED flashing blue and green and the phone remains like that. I tried factory reset but after I click yes it shows the LG logo then goes into a black screen (without the boot animation) + LED flashing blue and red.
So I tried finally going into download mode and attempting to return it to stock via LG Flash Tools, and like I said before the drivers were installed, but when I connect the phone to the PC it gives the message "Drivers were not successfully installed" and the LG Flash Tools fails to detect the phone. I checked within Device Manager and it says the LGE MTP device "cannot start".
So I'm pretty much stuck with a phone that doesn't boot, can't flash anything via adb or flash tools and no recovery installed. Can anyone suggest anything I can do to get this beast back up?

Hi,
I recently installed flashify on my LG G3. It was sometimes switching off during use and I thought to try and install new ROM.
Now however, it does not start. Going into recovery mode returns an error 'Secure boot error' and leads to black screen with red/blue LED fash. Going into download mode causes a message to appear in small text in the middle of screen 'Recovery mode' (not full screen like normal) but then resets after 8 seconds and goes to black screen.
Hence using LG flash tool to flash stock ROM is impossible because it resets itself after 8 seconds.
Please help!
Thanks.
