LG G3 not turning on ! - G3 Q&A, Help & Troubleshooting

Hi Guys I have a problem. I have a rooted LG G3 D855 with v2.8.6.0 TWRP and Blisspop ROM. Now my problem is that I was running SparTaxx ROM on it since yesterday. Today all of sudden it switched off and then I tried to turn on but it wasn't turning on... After removing battery and trying 2-3 times it turned on and then I went to TWRP and quickly flashed Blisspop ROM so that I can get things working and be on the safe side. Now after flashing it successfully the device isn't booting properly and getting switched off. It is not turning on at all. Only when I charge it it turns on then switches off.
There could be 3 cases which I am thinking but I could be wrong
1) Device is R.I.P
2) Battery needs to be changed
3) The device will either get repaired by some repair centre or maybe it wont work...
What do you think guys?
Any guidance or help is appreciated.

I think that is better for you flash a stock firmware with the LG Flash Tools in case of needs of warranty.
Is only an advice.

LG G3 Stuck in bootloop after Flashing Stock Rom

I flashed my LG G3 Because i felt that the sound was not working anymore and that it can be a software issue which it was a hard ware issue ( loud speaker wasnt connected because of screw) Anyways preformed the stock FW Flash following the guide that highonandroid provided to go completely back to a stock rom. After flashing i restart phone and the boot takes forever until it finally hangs on the tmobile screen. there was a point where i left it over night to see if it will turn on but it still hung for a good 8 hours. Ive done everything i can which can be that i preformed atleast hundreds of hard resets but nothing is working.. there was a point where i did manage to turn it on then i tried updating to lolipop and when it reboots the bootloop is back.. Please help!
I assume you opened the back to fix the speaker issue. Did you make sure all connectors are tight?

[Q] Phone keeps rebooting at LG logo without a charger

Hello everybody at the LG G3 part of XDA,
A friend of mine has an LG G3 and his phone broke. So he asked me to fix it. I myself am an Oneplus One user.
So the problem is really simple to explain. The phone doesn't work when there isn't a charger plugged in. When there is a charger plugged in everything is fine and the phone works normally.
So my friend tried to downgrade from lollipop to kitkat ( I don't know what he exactly did ). He doesn't have much knowledge about phones so ofcourse it went wrong.
Here is a video of what happens.
https://www.youtube.com/watch?v=VP8MUPsANes
I already did a full reset with the LG flash tool and put the stock 4.4.2 Kitkat rom on it.
I have also checked the battery and it has a normal voltage of 3.8v. My friend also told me that he already swapped the battery in a store.
I do not know anything about a stock recovery of an LG G3, but I tried to acces it and I could get in to the hard reset screen but when opted Yes for everything it got stuck in that same "bootloop". When the phone is in the Hard reset menu then it wil stay ON without a charger. In all other cases it wil stay in a "bootloop"
I asked another friend of mine who has a lot of experience with phones. He said that it might have something to do with the a file that keeps the battery in check in the bootloader or the recovery, but he wasn't sure which one.
Update: When I am on the lockscreen and I disconnect the charger the phone stays on until I touch the screen than it shutsdown immediately
Try to flash lastest kdz of your g3 model

Replace your battery. This is what happened to my phone last september, I thought it was a software related issue, but when I tried to insert my friend's G3 battery, it just boot normally. I think this is a common problem of the phone/battery.
P.S. I tried running stock again, tried on CM, AOSP, etc. but can't make my phone to boot without being charged, until I replace my battery...

That must be some hardware problem. Are you sure that if your phone is not refurbished because after flashing a custom rom in a refurbished phone such problems occur. You better take it to some repairing shop this is your only option in my opinion because the same problem happened with my cousin LG G3 mobile. It was refurbished and after flashing a rom it was nearly dead.

Nope, it was brand new when it was first released.
Just got a D852 basically new for $100 so will try to fix it and sell it (unless any developer reading this wants it?)

Help my G3 might be hardbricked (hopefully only softbrick)

Hello, I would like to ask if my LG G3 is softbricked or hardbricked. It has been a long while since it decided to boot loop. I tried to fix it but got no results. I tried to factory reset it, but the next day it didn't turn on anymore and got stuck in the logo. Note : the phone was experiencing some heating issue before it decided to screw itself up. I tried numerous troubleshooting from the net, none worked. I also did try to reinstall the firmware to stock again, it did boot but it can't get to the home screen. I then factory reset it again and tried using another firmware also built for my phone (it's LG G3 D855). It failed again at 33% while it was in the firmware update mode. Now that I have left it for a solid year, I thought that it would be nice to try again. Which I did, but it couldn't charge anymore and it cannot boot to the logo. I tried to go to the download mode but no response. I tried connecting it to my computer, but it only detects my phone as a charge only device, it also detects it on only several random occasion. I hope this is a softbrick and it can be fixed at home so I don't need to go to the store to repair it.
I'm sorry for the long explanation, I had been trying to revive it for months now and had no luck. How do I fix this, at least how do I get to the firmware update download mode again? I really really hope that anyone can help. Thankyou so much in advance.
