[Q] [HELP] LG G3 Random Reboot then Boot Looped - G3 Q&A, Help & Troubleshooting

Hi guys,
My sister's LG G3 had this weird bug where it restarts itself every time the Mobile Data is turned on. Several days after that it got stuck in boot loop, hell, it doesn't even enter the boot animation. It just completely restarts after the LG logo. I tried factory resetting the phone, which should've worked from my experience, but alas it still boot looped.
I wanna try flashing the stock firmware via Max Lee's tutorial but since the internet in my office is weak, I won't be trying this soon. Just wanna ask, is this a common problem since I saw many threads about this in Google Search? Is there a way to restore the phone without downloading a new firmware? What seems to have caused this problem?
Also what is the most stable custom ROM for the G3? The LG Stock one is soooooooo heavy. Thanks guys.

Do you remember ANY of the random stuff you did? I'm having the same problem and I've tried what seems to be every option but keep getting the loop
Wow I read that first anwser today and what happened low batt my phone shut down and on reboot yeah bootloop again great
and cant boot into cwm dont know why... yeah
I'm using LU6200 and I met this problem sometimes. Each time I met it, I try to Restore the phone to Factory Setting (Turn off the phone by unplug the battery, turn it on then hold vol- and power)
Don't use the AT&T ROM's on a Bell Optimus LTE. They are not made for our phones, and will cause bootloop issues if used.

LG G3 D850 (AT&T Variant) Bootloop after Stock Firmware Restore

Hey guys,
I used this guide to restore the stock firmware: http://forum.xda-developers.com/showthread.php?t=2785089
It didn't succeed. Near the end, when phone rebooted, it got stuck in a bootloop.
I see the LG logo, the android man for a few seconds until it restarts again.
What should I do? I tried running the factory reset but that too does nothing but reboot it (again in the loop)
I am also having this same problem, if anyone could help/shed some light that would be great
Me too. I take days trying to find the solution.

D855 immediatly restarts after boot finishes

Hey I need some help with my LG G3. It keeps rebooting after the Boot has finished. It shows my lock screen for about 3 seconds and then restarts itself. You have any idea how to fix this? The Problem startet 2 days ago, when the batteries runs out. After reloading and starting it just keeps rebooting.
I´m on stock LG android 6 with no Root or custom recovery
What I have tried so far:
- Used other stock battery
- Tried Safe Mode
- Flashed Stock Rom again
Could it be the battery? Damaged by going too empty?
Thanks for your help...

When I had this problem before if was due to battery. The phone restarts itself no matter what rom I was on. Buying a new battery was the solution I found. But if you tried another battery and still getting this, it might not be the reason.
G3 D855---ROM : Crdroid 7.1
Testet a brand new battery. Problem is still there.
Is there a way to backup my data before a factory reset? just can get into download mode. Is it possible to flash a recovery system with the lg Flash tool?

D885P Stuck in Weird Bootloop

Hello guys, my LG G3 fell into a dreaded bootloop suddenly. It started with random reboots while it was on, then it became a bootloop whenever it turned on again and if it somehow managed to turn on, it would reboot soon after that.
I thought it could be related to the ROM I was using (LineageOS 14.1), so I did a clean flash with another ROM (RR Oreo) but it kept bootlooping. Now, after another full wipe, I'm having trouble launching download mode or TWRP unless I plug it in a computer, but it keeps bootlooping even after that.
Can anyone tell me if this is a hardware problem or just a hard brick?
