[Q] LG G3 stuck in fastboot - G3 Q&A, Help & Troubleshooting

Hello!
I have one LG G3 D815 16GB wich is stuck on fastboot mode, all I can do on it is to enter the Hard Reset menu, but even if I choose Yes from that menu, nothing happens.
When I try to put it in Download Mode it does nothing, but after few moments after the phone is connected to PC on screen appears "[211630] Fastboot mode started".
Can anyone help me? The phone has get bricked from nothing, I didn't do anything to him to get it bricked.
If I try to power it on normally it remains stucked with LG logo on the screen.
Can anybody help me? With a tutorial or something?
Thx!
PS: I didn't installed any custom firmware or something like this on this phone. I attached down there a photo with the screen wich appears after I connect it to PC.

The same problem as me: http://forum.xda-developers.com/lg-g3/help/lg-g3-hard-break-t2977485

No one can help me?

Do you have warranty?
I believe jtag is only option here as you cant enter anywhere.

Happened to me today, this one worked! http://forum.xda-developers.com/showpost.php?p=57655028&postcount=15

Search for G3 unbrick here in xda or google. There's a few threads about how to "unblock" the phone.
I've done it twice already because of tests on it...
This thread is supposed to also work on the G3. Thought it might help:http://forum.xda-developers.com/showthread.php?p=50775936

Hi.
I had the same issue. All i did is do a hard reset on my phone by holding volume down and power button, when you see lg logo release the keys and press power button as fast as you can until you see hard reset.

My phone is LG d855,and my English is bad,i hope you can understand
Can anybody help me?
did you try entering Download mode?
Phone stuck in bootloop, help please
wrong trhead
Are you sure you there is no fastboot and no download mode?
You can enter download mode by pressing and holding the “Volume Up” and connecting the USB cable from phone to PC
If it works then you Soft bricked it...And you can use this guide to fix it:

BUT if that does not work then you Hard bricked the phone
I had that problem because of flashing with faulty win8 drivers...no download mode or fastboot, all i got was security warning and bootloop. The only way you can fix hardbrick is through JTag, but i don't know if you can fix it without paying someone money, because you need special hardware to do it. You can find people on ebay that can fix it but it will cost you 30-50$.
I sent mine to warranty...they didn't know what was wrong with it and couldn't fix it...and so they just replaced the motherboard. If you have a warranty then send it and do NOT!! tell them you flashed it or rooted it. Tell them you don't know what happened...The chances of them finding out is very small.
If ebay and/or warranty not work, then there was an article on the Internet to fix a hard brick but for some reason it is now password protected...i do not know why....You can send the owner an email so he can give you the password.

But then again you cant be certain this will work either.
Conclusion: Fk LG...They don't want people upgrading their slow buggy software.

i cant enter download mode,always turn black after LG logo
Disconnect cable from pc and phone
Press power + vol -
You will get first black screen, keep pressing until lg logo appears and it shuts off completely.
Then press just vol + and reconnect cable to computer.
That should leave you in download mode or fastboot.

[Q] Please help with BootLoop after screen replecement

So i had a cracked screen, ordered a new one of aliexpress. Exchanged it, turned on the phone and got the boot loop.
I read that exchanging the screen acts like a new hardware ID and this is why i get the LOOP.
So i wanted to turn off the cores:
- installed drivers from LG.com
- used original cable
I hold the volume up button, plug the phone and still get to the boot loop. No download mode. How could my download mode be erased if i changed the screen?
I also sent the phone into warranty but they said because i exchanged the screen they will not fix the boot loop!!! LG are a bunch of assholes but that is a story for another time.
If you can think of something regarding to how i can get into Download Mode, please let me know
Thank you
UPDATE: I changed the cable and now the download mode icon appears and after 3 seconds the phone resets and download mode appears again (if i keep pressing vol up) and so on.. It does not actually enter the download mode.
is there any way to force bootloop???? with a kdz file or changing something with root permision ??? i need to send my phone to the SAT

Dead LG G4, no recovery or EDL

Hey everyone
My LG G4 (H815) suddenly turned off when i was using it, and it showed no life when i tried to boot it up again. Its completely stock, no custom recovery or custom firmware is installed. I cant boot into fastboot or EDL mode. I tried the button combinations as well as the test point method but i just cant get it to enter any kind of recovery mode, the screen just remains black (no backlight either). I installed the Qualcomm HS-USB drivers and when i plug my phone in my pc it gets recognized by QFIL. I tried flashing the fimware but it always gives me the Sahara unable to read packet header error. Can anyone help me?
Thanks in advance.
Have you searched the forum and tried any of these ?
