If I power on the phone without a USB connected I see a black screen for 1 second and then it shuts off. When I power it on through USB the black screen stays on. No download mode. Windows detects it as Unknown device. I have the drivers downloaded and LG Flash tool started but it won't recognize it as a serial device.
History:
Phone came with 12B. Flashed original stock firmware with LG Flash tool. Rooted and flashed twrp. Installed SkyDragon rom and running that for a few days without issue. Look at phone today and it's off and won't turn on. Maybe the OTA update came and bricked it?
Turns out the battery was bad. The black screen is actually supposed to be a battery indicator with a question mark in it. I put in another battery and it works.

Hello,
A friend of mine has an LG G3, no root, no costum rom, everything is on stock.
Today he was writing an SMS but then the Devices froze. After a few Minutes He pulled the battery but instead of booting back up the Devices Stayed Black with no LG boot logo or anything else on the display. But the Notification light keeped flashing in all different colors. After a time The LED stopped flashing. We tried to boot in recovery, but it stayed black. We tried to charge the phone but that didn't change anything. When we connected the Device to my Computer windows Installed some drivers but thats it. It just says that a devices is connected. Trying to access the G3 via ADB did not work as well.
So i ask you guys, is there anything more we can try or do i have to send the Phone to repair? Its only a few Months old, No branding, and everything is official.
Thanks in Advance

Sounds like a motherboard problem, what does it say under devices on the PC?
Screen might have died, or have a faulty contact. When the phone boots, the LED goes through several colours. If the screen is locked, the phone won't show up on MTP and ADB won't work either. If the phone is on silent, it won't make any noise.
Boot it up, wait for the LED to stop changing colors and try calling it
UPDATE
Thanks for your answer, but the problem kinda solved it self. After half a day just lying around, the phone suddenly booted without any problem. Is works flawless by now. Weird stuff somehow.
I have the same problem except mine isnt fixing itself
Im having trouble turning on my lg g2. My phone died last night and is unresponsive if I dont have it plugged in (like a normal dead phone) however, when it is plugged in the LG boot logo appears but then disappears after about 4 seconds followed by the red light blinking a couple of times and then the cycle repeats. I had my phone charging all night and i woke up to it still being in this cycle.
A couple of side notes:
I can enter download mode, although i am unsure if my computer is able to recognize the device
I am rooted
I cant enter recovery mode. the closest i have gotten is the "recovery mode screen.." then the phone powers off.
my device is an ls980 on sprint
Any help is appreciated and I am willing to factory reset as a last resort
did u find aby solution? as I am having same problem wont tun on or charge at all
If you can enter download mode, do it and see if the computer recognizes it. If it does then go ahead and flash the stock firmware using LG Flash Tool. If it doesn't install the LG drivers found on XDA.
So I have an G3 (D885) that sundenly when it was on my pocket vibrated and died.
When I try to turn it on, it keeps the screen of and the led keep changing color. I've tried to enter download mode and install the stock firmware but it does not show anything on the screen, but in the computer I can get the COM41 working but the methods for flashing fail.
I know that the screen is ok, if I plug the phone without the battery it goes on and show that the battery is not present for everything else it keep off.
Can someone help me?
Hey everyone,
This is an LG G3 D855, initially running on stock ROM, which shows me a completely unknown state of bricking. From what I gather, its a kernel crash.
1) Normal power button boot results in bootloop, where it restarts after a few seconds of showing the LG logo/splash screen.
2) When restarted in recovery mode, the phone is able to boot into it, shows the factory reset screen and when I confirm the reset, reboots the phone into bootloop.
3) When I hold the volume down key and connect the USB cable to boot into download mode, it temporarily shows the download mode logo and then reboots into bootloop.
4) When connected to a charger, it shows the inital battery charging screen and then reboots into bootloop.
5) When I remove the battery and connect it to a windows PC, the device is not recognized by LG PC Suite or the device manager, even after installing the drivers for the phone.
Please suggest me possible ways to think about debugging this issue. I'll be uploading the videos for each of the point shortly.
Thank you.

Try a new battery. G3 batteries die without warning sometimes and will put you into a bootloop once they fail.
If you truly were bricked you wouldn't get, albeit briefly, download mode or the factory reset screen and the phone would show up as a qualcomm or some other device on your pc.
As far as #5 goes, you need a functioning battery to get into download mode on the G3; some other devices - samsung I think - will allow you to load software without a battery but for us that is not the case.
Hopefully a new battery sorts you out.
Good luck :good:
*Anker makes a decent replacement if you can't find an original LG battery.

That might just do it. I think the battery might have drained out due to broken charging port or some other reason and then died out. For now, I have an external charger on the way. I'll be trying that, and if not, the next step I'll try is to replace the battery itself.
Will keep updating.
Update: It was a battery fault. I got a new one off Ebay to test it and it has been working fine until now. Will probably change it for an extended battery later.
Hello there everyone! Let me explain my problem:
Backstory
I have a Samsung Galaxy Nexus GT-i9250 maguro since 7-6 years or so. I've been flashing some roms into it and everything went well since a week ago.
I had installed from a very long time this version of CM "cm-13.0-20160921-NIGHTLY-maguro" and I have not updated it, so I basically was running that from a very long time.
Three weeks ago the phone started behaving strangely, it was closing automatically, and I thought that it was a temperature problem (being a very hot summer) so I did not worry too much.
Everything was working fine, charging and connecting via USB .
Problem
Last week the phone once again died and I tried to boot it up normally as I would normally do, but nothing happened, not even the Google logo popped up.
So I removed the battery and put it back in, the phone booted up to the Google logo, then after two or three seconds the Google logo flashed like brightness went up to 100% and black screen.
Went into fastboot, booted TWRP to see if that was working, and the recovery was working fine.
Things got worse.
At the moment
I cannot get the phone to do anything if it's not connected to a power source.
If the phone is connected via USB, or charger, I can get it to go ONLY on fastboot, and download mode. If I unplug the phone while on fastboot or download mode, the screen brightness goes up to 100% for half a second then it glitches out and goes into black screen immediatelly. I can not access bootloader nor recovery mode from fastboot, because the phone reboots, shows the Google logo and then it dies.
What I tried
Thinking that maybe the ROM went crazy, I followed this guide to flash the phone with all the original ROM and recovery (I downloaded "yakju-jwr66y-factory-4cadea65" and followed the instructions of the guide).
Nothing changed, if the phone is not connected to a power source, it is basically dead, if I put it to a power source it shows the charging logo for a second, then black screen, and I can only boot up fastboot and download mode.
I don't know if this might help but I've also tested the battery voltage and it seems to be fine.
Last thing, if I connect the phone to the PC (with the battery or without) every 2 seconds it shows up that an unidentified device is being detected.
I currently am using a laptop running windows 8.
On my desktop computer the same thing happens (the device detection) but from device manager I see a OMAP4400 (something like that) popping up but at the moment I cannot use my desktop PC since I'm traveling.
I would really like to know what happened to my phone, any answer will be appreciated.
Thanks in advance!
Update [solved]
After doing some research and trying different methods I gave up. But then I realized that maybe trying the stupidest thing could be the solution, so I went to a phone shop and asked them if they had some sort of test battery that I could plug in my phone temporarily to see if it was booting up.
Turns out, it was the battery.
I bought a new battery and now the phone runs smoothly like it's new.
I feel so dumb and I'm so sorry if I've made some of you people waste your time by reading the poem of the first post.
Hopefully this will someday help someone that will have the same problem of my GT-I9250!
