[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.

Lg g3, started restarting randomly and now wont go past the lg logo without crashing

Hey guys
i always end up coming to the forums after i have tried to fix my phone for several hours
so far i have tried several times to revert it to stock and it seems to revert and boot, when i almost finish the setup (entering wifi, logging into google) it turns of and then attempts to reboot, it then gets to the lg logo and then crashes and so on, keeps going until the batterys flat
I have tried to install several different roms, tried another kernel, revert it to stock and it keeps happening!
Can anyone help me? I really need my phone!!!!!!

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

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?
