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

LG G3 d855 rooted (sudden demigod TZ-Kernel crash)

So..I have this d855 2gb 16gb variant.
It is rooted,it has cyanogenmod 13 nightly with kernel adiutor(with cpu governor set).It worked like a charm (3 months till the last update).
Today I launched youtube app and all of sudden it restarted..and it kept restarting in a bootloop.( he passes lg logo and enters the android one and after 10 15 sec it reboots.)
I tried to charge it,change batteries but with no luck.
I deleted dalvik cache and cache..but still nothing
then I tried to flash again the rom and there the phone gives me 35% of the times demigod:TZ crash with green screen.. and the other times demigod:Kernel crash.
I decided to delete kernel adiutor folders hoping for a luck..nein. ( using twrp)
I can access TWRP,it works fine but when flashing sometimes it gives me that demigod errors.
I can pass the LG logo but it gets stuck at android logo then restarts..or at finalizing/preparing apps.
baseband-modem: 21C
cm version: 13.0 2016 10 22
any help?
UPDATE:
Windows detects my phone as "LG Android Usb Device".
UPDATE2:
after leaving it resting one night it booted.
i still need help fixing it because it's not normal.
It worked fine from 6am till 1pm.
Now it freezes and restarts randomly.
need help guys..
Flash stock rom and test for crash couple days. If still crash, then if your G3 has still warranty to service. Probably MB broken.
If no crashing then root and flash rom

Unfortunately it gave me demigod: hw reset and no longer wants to load TWRP or download mode.
It restarts at the logo or at the android loading. I'll give a shot for the warranty.

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?

Dead ZenFone 2 or something else?

Hello everyone
I got a ZE551 ML Z3580, 4 GB and 64 GB. It runs on Resurrection Remix 5.7.3 (MM) and it was a great phone til I had to change the screen two months ago.
Then it worked fine until this morning. I was using "Asus Pixel Camera" and the phone just shut down and vibrate 2 times (the same vibration as when the phone starts).
I tried to start the phone again but it never went over the boot animation. It shuts down 2 seconds after the beginning of the boot animation.
I tried to reinstall the ROM but the phone shut down before the end of the flash. I tried to flash with the ROM on a USB OTG and it wasn't better. I tried to put the file on the internal storage (sdcard in TWRP) but the copying of the file never ended and the phone shuts down/restarts. I don't know what's my problem, it never happened before. Just hope it isn't a hardware problem.
Can you help me?
Thanks

Can you boot to twrp still ?
If you can
Connect wall charger , boot to twrp . select reboot and power off.
See what battery is doing after.
Sounds like a battery issue to me. Let it charge for a long time (like 24 hours) then try again
Thank you, I'll try it tonight. I just ordered a Xperia X Compact to replace it.
So, I did it with the phone plugged to the wall. And now it's okay. It seems to work fine but I don't understand how this all thing happened.
Thank you

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 ?
