Hi, first of all I must say that I never used any custom rom or flushed my phone yet. I still use the stock rom provided by LG. So I was typing a text a message today and suddenly phone locked and I couldn't do anything. I clicked power button and pressed again to get the main screen but some part of the screen was total black and some part was just fine(still I can't do anything btw). So I just pressed power button longer to close; I could close it but then when I tried to boot, I just got stuck at LG logo and it's still the same(30 minutes passed!!!). How about that? What should I do?
Remove battery.
Wait 10 seconds.
Then put battery back and turn it on again.
I just did it; over 3 minutes passed and it's still stuck at LG logo!!
my advice alhough i have not worked with lg phones would be to reinstall the stock rom. i am unsure from your post if you were using a custom rom when this happened when you bot the phone if its like the htc phones you can hold the voldown and power buttons to get into what is essentially the bios of the phone i hope this helps

Then, connect the phone to the usb in a windows computer.
Run the LGMobile Update tool.
Go to the menu Customer Support/Recovery Phone
Follow the instructions there.
I connected the device via USB and opened the Recovery Mode in lg mobile update tool, but it doesn't recognize my device. I already installed usb drivers and they were working correctly couple of days ago. What else I could do? Any help would be appreciated...

Well, it seems like I have to do one, because I fell that it'll never come back so where should I begin for a hard reset?
Remove battery
Put it back
Hold Volume Up.
While holding, plug in USB cable to computer.
Your screen should say S/W Upgrade.
Run LGMobile Update.
Customer Support/Recovery Phone.

I did exactly what you said. It could successfully update the phone, it's still stuck at lg boot logo. So the next thing I should do is a hard reset?
After what you did, it could take a few minutes to start, that is normal after rom changes.
I'm not aware of a 'hard reset' for the P970, beyond what you did.
I think this could be an indication of a hardware failure.
Hello.. I flashed the M preview on my N6. It was too buggy for me so I tried restoring my nandroid backup I made. After that, I don't really know what happened. The toolkit searched for adb fastboot on my phone and thats when the screen went black and a quick pop up saie: "Your device failed verification and may not work properly!" It wont do anything when I use the combo volume and power. If I hold down the power for like 15 seconds , the "Google" logo appears and then it quickly says: "Your device failed verification and may not work properly!" It only stays on the screen for like 2 seconds. I have never seen this before. Can someone please give me some advice? It wont turn on. Thank you so much..

Use fastboot and flash a factory image.
My phone won't stay on long enough and I can't get into recovery or fastboot mode ...
Okay so I'm a newbie to rooting. And I was on this step where I let the tool install some files to my phone and it said to unplug and pull battery, the next step said to hold power and - volume down button and release power when I see the LG logo while holding the - volume down after a second quickly hold power and - volume down to access factory data reset and settings. So it restored my phone back to factory settings and no root, the video said to try again but the problem is that my phone will power on anymore and is unresponsive when I charge it. So I took the battery out for a min. and the phone turned on but got stuck on LG logo and freezes then it shut off. I tried to boot it up again on LG logo screen, the corner it says Secure booting Error
Error code: 1009
MODIFIED!
And it froze and shut off. Now whenever I try to boot it up it gets stuck on LG screen and shuts off or when I'm in factory reset it freezes when I press yes. I put it into download mode and try to install the LG G4 stock kdz file but my computer couldn't connect with my phone for example, I plug my phone into the computer via USB but nothing, no sound and no charge now it won't turn on at all. I hope this wasn't too hard to understand and I'll greatly appreciate any kind of help, thank you.

I wonder if LG or T-mobile is pushing an anti-root tool that hard bricks the devices. My device was working fine until this morning after my alarm went off - Mind you, I have been rooted since the root came out. I unplugged the phone, put it in my pocket, and it got really hot, then it does the same as yours; except, my phone shows bootloader:unlocked when i try to reset it. So, yeah, you are hard bricked. No recovery from what I hear. U got a paper weight. I do not believe any of the G2 or G3 fixes will unbrick our devices. I think it may need a jtag.

I don't think I could do that, since my pc can't connect with my phone. I plug my phone via USB to my pc but there is no connection

Look for the kdz post and follow those instructions and your phone will be like new.
I have a LG L90 D410HN that is hard bricked, it does not go into recovery or download mode. I had installed some time ago the Lineage 14.1 rom.
I'm trying to follow a tutorial I found here: https://forum.xda-developers.com/lg-l90/general/guide-unbrick-hard-bricked-l90-variants-t3173429, but when I connect it to the pc (without battery), even I have installed all the drivers, it only appears as Unknown Device (Device Descriptor Request Failed) and when I put the battery, it is not recognized just remains rebooting in the LG logo. Any suggestions on what I can do? Thank you in advance.

Nothing specific, I turned the phone off and took out the battery only. When I turned on again, it has been stuck in the LG logo, restarting endlessly and cannot enter download or recovery mode. As soon as I put the battery in the phone, it turns on without pressing the button.
What I think may have happened is I have removed the battery before the system finished shutting down or something like that.

What happens if you boot phone without battery inside but connected to charger?

After a moment that is connected, the battery symbol flashes with a yellow triangle next to it with a question mark in the triangle.

Can you also try booting the phone with battery inside and charger connected then remove battery once started booting and see if that works. Also, how did you try to get into download mode.

The power button is shorted, I measured with a multimeter to confirm. I think only technical assistance will save my phone, right?

I think you have to change the power button or wiggle it a bit for it to work then.

Ok, you are welcome. But for temporary fix the power button probably got stuck pressed so try to pull the button out so it is not pressed anymore.
