BOOTLOOP FROM MM 30B-Reason Faulty battery - G3 Q&A, Help & Troubleshooting

I was using MM on my G3 D855 for the past 1 month. It was running ok with random reboots in between.
Yesterday it went to the boot loop continuously with no reason. I tried to flash again 30B KDZ file but its the same
problem again, tried resetting from the stock recovery and installing again without any luck.
Tried most of KDZ files flashing bit stuck at 4% and stops.
Also tried using TOT file with showed error message that the model number is not same.
Now iam out of any options..pls somebody help to get rid of this boot loop.
thanks in advance.

i suspected it after doing some reading in xda...tried replacing battery with another G3 and it seems to
work perfect without any issues.
The battery is still showing some charge like 75 % , is it because faulty battery or some software bug
Any ideas
Thank you for your reply.

Because it's faulty

Bricked D855

I think i bricked my D855.
I was on Lam Hoang 1.8 rom, but i wanted to restore the original firmware v20h.
I've done the same thing i did many times, i tried to use kdz tools to flash the stock rom.
Everything was working fine when i got stuck at 10% in S/W Updating process.
I unplugged my phone after about 30 minutes, then i tried again, with the same result.
So i tried the TOT method, but the problem is the same, stuck at 10%.
It seems to be stuck on modem installation, as the last line in the log is MODEM.
Does anyone know how to fix this?
Thank you.
Resolved.
It was my pc fault.
I'm sorry.

Random Reboots and Bootloops

I flashed 30c firmware with flashtool 2014 over rooted 21a (i think) on my D855 from Greece. I selected the normal flash to keep my files and apps, phone mode: DIAG and didn't clear the update registry. Phone worked normal for a week and then went into a boot loop. The phone randomly restarts and goes into loops for a while and then snaps out of it.
I have tried the following and none have fixed the issue:
-Replaced the battery.
-Upgraded to 30f over lg pc suite hoping it would fix it but it didn't.
-Flashed 30c and 30f over LG Flash tool with CS_EMERGENCY mode and cleared the updated registry.
-LG Flash tool wont flash any older lollipop kdz I tried. The phone screen flashes once but stays at 0% and then I receive a phone disconnected message.
-Put the device into safe mode and used the option on lg pc suite to fix upgrade errors. Didn't fix anything lol
-Tried factory reset. Nothing happened after I selected the yes on the confirmation.
-Tried to use LGUP hoping to install a lollipop kdz but it gives me an error message that I have to select a known model. Restarting the app and the phone didn't work either.
-Tried a guide on how to unroot and return to stock with the kitkat .tot file .
I really have no idea what else to try. Any help would be greatly appreciated.

Replace the battery
I have the same problem and i got into the problem for the same reason.... the random rebooting that everyone says is down to the battery is something more sinister... i have tried 4 different batterys that work perfectly and it still happened i flashed a kdz and now i have a bootloop and no OS none of the other kdz files work neither do the tot files and lgup doesnt recognise my device... stuck...

That's the first thing I tried on my list of failed attempts to fix the problem as you can see... Brand new battery. No change.
DjCaprio tried 4 different batteries as you can see.
This is just terrible!

I tried removing the battery while connected to the pc via usb already. The other trick that involves editing a file requires root.
My phone started flashing the blue screen of death today so I finally took it to LG so they can check it out. Either way thanks for trying to help.

problem with lg g3 bootlooping when installing stock firmware

Hi guys
LG G3 looping on boot screen every time,
I had TWRP with fulmics rom installed and one day it just shut down, i tried turning the phone on but it shows the lg booting screen and then reboot, and it goes on like that, I tried installing different roms but always the same problem, i
should mention that i tried cloudy rom and i did actually work but when booting the phone it had this problem that the wifi and bluetooth won't activate, i searched on the Web and a lot suggested that is a battery problem,
so i thought the previous rom worked well so let's change this rom,I installed a lot of roms and the boot looping problem shows up every time, so i thought **** it let's get the stock firmware,
and when resetting the phone to stock firmware it's stuck in the rebooting phase at the end, boot loop again, and now that I've lost TWRP i only have the firmware solution that is not working, this too was mentioned to be a battery problem,
and i bought a new battery and nothing have changed,
tutorials that didn't work for me : http://lgg3root.com/lg-g3-stock-factory-firmware/ http://unbrick.itcse.com/unbrick-lg-g3-stuck-on-factory-reset-2/

LG G4 Stuck In Firmware Update - Stock Reset?

Hi, recently decided to reset my phone back to stock as I had some trouble with a few programs after resetting my phone. I tried factory reset but the programs didn't work so I decided I would try to just restore to stock and start fresh. I followed a guide on how to do the stock restore using LGUP/LG Flash Tool. I followed the guide and put the KDZ File into the program and pressed cse flash. The program worked till around 12% then it got stuck and just didn't work anymore. It said error so I kept trying over and over as some guides on this problem said to keep trying.
Nothing has happened and my phone is now stuck on firmware update screen. I have taken the battery out multiple times and replaced it back in and turned the phone on but it automatically goes to that screen after showing the lg logo. I have tried the volume down and power button factory reset but that doesn't work and tried getting onto download screen if that was any help but couldn't do that either. Now I'm stuck here... Any help? Don't have any other phone and can't afford to get a new one so I would like to try fix this anyway possible.
After failing the flash update thing the program says failed my phone says 0%. It went to 1% once and then just went back to 0% after it didn't work. So don't know if it's been changed in anyway. All help appreciated.
Did you have LG up set at refurbish or upgrade.....

I did refurbish first as I wanted to start new and it didn't work even though I did it a few times. I tried upgrade after and still nothing. Also have tried Uppercut and that does the same as normal LGUP.
The furthest % it got to was 19 on the computer and 8 on the phone and then it just stopped again. It usually stays between 11-19%. But most of the time 11%-16%
Have you made sure that it is the right region......
Try to down load just tot file and try that....

Where would the TOT files be? Can't seem to find any for LG H815 v20i ?
And what program should I use to do it?
