D885P Stuck in Weird Bootloop - G3 Q&A, Help & Troubleshooting

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?

[Q] [HELP] LG G3 Random Reboot then Boot Looped

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.

D855 keeps rebooting even after rom change and LG Flashtool procedure

Hello,
my phone is stuck in reboot loop since yesterday.
I have this phone since 2 years. It was rooted and on fulmics 5.3. Since few weeks i had random reboots, more and more often, since yesterday when it became unusable because of the reboots.
It wasn't in bootloop, but the phone starts, the rom loads, and after some seconds it reboots.
So i changed rom, went on exodus, but the problem remanins. The rom boots, and after 1 or 2 mins it reboots, go in bootloop, then starts and reboots again.
Today i've made the Flashtool procedure to go back on stock, but the problem still remain. The rom booted, changed the language then rebooted again.
Wad can i do now?
Thanks
perhaps to be hardware problems, there are some parts of poor contact caused by repeatedly reboot
its not the problem of rom . its a battery issue
replace battery
Maybe this ^
I'm using phone connected to power and it seems to works!
Thanks!
Buy a new battery

G3 D855 bootloop, sort of?

Hi guys,
I need your help!
This morning opend up snapchat and my phone just randomly turned off, since then its not booting any further than the LG logo, it just keeps restarting.
I have the latest BlissPop installed and flashing another rom also doesn't work because when flashing it also turns itself off.
What is going on and how can i fix my problem?

random infinite bootloop.

Hello there
After my phone randomly rebooted while watching a video it ran into a bootloop.
I had been running LineageOS for the past couple of months and everything was fine up until yesterday.
I have tried restarting, and everything and only managed to reflash twrp via adb and force it to boot into twrp, but now it's stuck booting into that.
when I try to boot into lineage I only see the boot animation of lineage that never stops, and when I boot into twrp I see the boot screen of that, which never stops.
I've let the phone do its thing for so long that it has run out of power, so it's not something that just takes a long time. I feel like this thing is completely bricked now.
Anyone maybe got a solution? Any help would be appreciated.
Hi,
Think I might have the same issue, except I didn't flash or modify anything on the phone. I'm running all stock ROM and all the rest.
Stuck in a bootloop in recovery mode. Mini partition does not recognise the phone. Same with QPST. QComDloader does, but only for a few seconds, so whatever I try it's not fast enough before the next reboot...
Whats are the options? I don't want to have to send it back to China

My g3 bootloop

Hello everyone
My G3 (d855) (fulmics 8.0 ) started restating yesterday. when I turn it on, it restarts on lg logo before android come up and it stucks in a loop.
At first i thought it's a software issue and I did a factory reset usinng TWRP but still the same issue.
I reprogramed the same rom and then I programmed Official rom and still the same.
Today I found sth out. sometimes phone starts normally or after just one bootloop when the charger is pluged. so i think the battery may have problem.
I tried using a power supply to turn the phone without battery but it stuck again in bootloop. (phone draws 1.1A max)
any idea ?
