LG G3 Restart tried everything - G3 Q&A, Help & Troubleshooting

Hi,
I have searched this forum a lot and found many solutions to my restarting problem but i am still not successful in getting rid of this issue. Let me explain the problem and solutions i tried without success.
Phone Specs
LG G3 D-850 AT&T When i got it, it had stock rom lollipop 5.0.1
Problem
It restarts automatically. It restarts whether i am using it or it is in idle state. It restarts even when being charged by Laptop USB cable. It restarts more often when battery is low like 5%. It restarts even without wifi without sim card.
Sometimes my phone does not start and i have to pull the battery out and put it on charge for a while then insert battery in and then it is able to start.
Solutions i tried but without success
1- Bought a new IbestWin Battery from Amazon 3000 MAH but the issue is still there. I also tried my colleague's OEM battery and restart was still there. His phone is also Lg G3 D850 ATT but from a different vendor and his phone is working fine on a custom rom of Fulmics marshmellow.
2- I tried custom rom of Cyanogen 12.1 lollipop through TWRP recovery but restart issue worsened, In fact the cyanogen did not always load correctly, phone shuts down at cyanogen pulsating logo.
3- I reverted back to stock rom successfully using the .Tot and DLL method (KitKat stock rom) but it even restarted more. I never installed anything, only built in apps already in the rom.
4- I read somewhere that putting a piece of paper between battery and card slot might resolve it, but still no success.
I took the phone to a repair technician and he thinks that this is either the software issue or the battery issue, phone seems okay.
Kindly help me resolve the issue.

Any one?

Did you try factory resetting the phone ?

Yes i did (By pressing power button and volume down key) but still the frequent restart issue is there. I notice one thing though, that on Stock rom lollipp with stock firmware the restart was less as compared to stock Kitcat rom (.tot and dll). That leads me to believe that it is related to software and not hardware.

[Q] Battery charges only when on?? NO MTP?

Device: Rogers SGH i747M Android 4.1.2 Rooted with CWM Recovery and AxisM ROM
Problem 1: Phone charges when device is on, when device is off constant vibrate cycle.
Problem 2: Can't connect Phone to PC..
Problem 3: When phone is on and charging and i remove charger the phone still says charging for about 30 seconds. So there is a 30 second or so delay after the phone realizes i unplugged it.
I had my phone rooted for a while now and it's been working perfect. Up until i removed the stock ROM and installed the cyanogenmod for at&t. Once i removed my stock ROM the problems began. I have attempted to use 5 different roms all same problem. I have tried 4 different USB cables, 3 different computers.. I have a second device that's a duplicate that works perfectly fine with the exact same rooting technique, same recovery version, had the same ROM. One works perfect other is sick with this new disease.
Any ideas and help guys?

At this point, I'd probably try flashing stock and doing a factory reset (backup your stuff first). Start fresh from there. If the issues persist, might wanna get a replacement but my guess is that starting fresh should fix w/e is going wrong.
Once you've tested fresh stock ROM, go ahead and try flashing/rooting to see if the problem comes back.

Marshmallow Update followed by Bootloop [EUR]

I just got the official update to Marshmallow and I decided to just do it since it is official. It downloaded and then installed. Then it rebooted and showed that "apps are being optimized" screen and after that a bootloop of the lg logo. Rebooting doesnt work only if I take the battery out but afterwards there's still a bootloop. I also didn't do root or anything else to my device. I can not enter download mode or recovery either, but honestly idk if it has worked before.
Can anyone with probably similar experiences help me? Thanks in Advance from Germany

I have exactly the same issue. I have a German-bought LG G3 d855 updating this morning to Marshmallow. It is now caught in exactly the same boot loop. I get the LG logo, for a few minutes (the brightness changes during this time) followed by the "Android is updating..." app optimization screen which optimizes my 44 apps before going back to the logo in a constant cycle. Then my 44 apps get optimized yet again, and on it goes. I can't enter recovery, none of the button combinations has any effect. Phone has no mods, and was working fine before this.
Does anyone have any ideas?
Hi,
Similar issue here, my phone updated today (also no root, no mods) and for a couple of hours everything worked fine (just some missing apps after the process, but ok), then I went to flight mode and back and then it started with the reboot loops.
The reboots on my phone happen after some seconds in the home screen, so I have time to try to set it in flight mode again, and in some cases, after this it stops rebooting, but in flight mode, with no connections at all.
I'm trying to remove things to avoid doing a factory reset by now, removing cache didn't help...
Is your phone rebooting also after loading the home screen? or it just loops in the LG screen or in the apps update screen?
Hello,
I had the same problem. Just hardware reset the device and the device will continue from optimizing the apps
Instructions on how to hard reset see the video find on youtube "How to Enter into Recovery Mode on LG G3!"

Hi
I managed to recover my phone, BUT I didn't manage to recover my personnal data... I had to reset everything...
My method : with this tool https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwi9oJnC66bMAhWHDsAKHY_cBVQQFggdMAA&url=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2683691&usg=AFQjCNGG5q9UKA6oKXlahEEOksUo8faGrw&sig2=cTz4bAtdqp4BEut2S4B2GA enter your imei, and download KDZ file, latest directly from LG server.

You can try "normal flash" at the first time, but if it doesn't work (for me it doesn't work) you will have to choose "CSE Flash" and it should work. But you will loose your personnal data. So be strong.

Bro Thank You so much ive been searching for solution the last 2 days and you finally saved my life Thank you Man !
i have the same problem....after the stock firmware has been restored,what method is used to get the proper working marshmallow upgrade?
I went from 5.0 to 6.0 using the LG PC Suite.
0 problems, 0 reboots, quick and fast. Did you update through OTA?
yes i did but still boot lop............is it the battery?
so ?
Same problem here, did you find a solution ?
New G3 from LG but back in bootloop after 24h of use.
Thank you.
I got the exact same issue, neither hard reset or flashing firmware works. Is there any other solution or should i start looking for a new phone?
Edit: Somehow it works just fine now lol. Tried flashing it like 3 times and hard reset twice and now after an hour of constant optimizing apps bootlopping i pulled out the battery for like the 100th time and now it works, what the hell. Looks like my G3 will die soon tho haha

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?
What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.

[HELP] System UI has been stoped. Even I can't flash my device to stock.

Im in a big trouble. i was using fulmics 6.1 on my LG F400L. it was running well. But i tried to install Android N-ify to my phone and after booting up my phone says " SystemUI has been stopped" and I can't access it anymore. its not a big deal since i can't even boot into recovery. I don't know why hardware keys doesn't work for me. So only one option is left for me is flashing my phone back to stock.
Here is the main problem. Via KDZ method my phone stucks at 2% S/W. maybe its for Fulmics 6.1
Again if I try to downgrade via LGUP my phone is showed as unrecognized.
Now , how can flash my phone ?
what method should I try ?
Please help me.​
Hmm are you certain you can't boot into recovery? Holding the power button to switch off your phone and then booting directly into recovery? Or removing the battery and booting directly into recovery?
Nothing happening on OS level should keep you from booting in the recovery..
As for "Device not recognised" -- I had that myself, and usually it's due to the COM ports in Device Manager in Windows. There are a couple of guides for restoring to stock around the forum, you'll find most helpful.

HELP PLEASE.Is there a way to flash or root AT&T Note 5,stuck in boot loop mode???

HELP PLEASE.Is there a way to flash or root AT&T Note 5,stuck in boot loop mode???
Hi to all
I'm member on XDA for a long time,but I really am a newbie considering rooting,flashing and messing with the phones.
Yesterday ,my At&t Samsung galaxy NOTE 5 restarted by itself and started doing that constantly.Maybe because the memory was almost full so the firmware didn't have enough space to run correctly ,I don't really know.
So I decided to do a FACTORY RESET in order to refresh the phone.I backed all up (it did restart few time while I did that but I managed to finish it).
After I did the factory reset and wiped the cache,I rebooted the phone and that is when the boot loop started.
Once or three times came back and started the phone up to the first settings (I managed to put in my google username e.t.c. but after a minute maybe it freezes and restarted by itself again)
I tried again another factory reset but the boot loop continues.I tried many time to turn it off,it restarted up to INSTALLING UPDATE......then tried to turn it off completely (Volume down+Power+Home button) and somehow I managed to turn it off.
I thought that I can come here and find the instructions on how to FLASH it with ODIN,but I couldn't find the stock firmware for AT&t Note 5.
Then I remembered (and read on internet) that the bootloader on AT&T phones is locked !!!!!
I searched some threads here for at least how to root it ,but I can't find anything clearly.
So I'm asking you for help: IS THERE ANY SAFE WAY THAT I CAN DO FLASH OR ROOT MY AT&T SAMSUNG NOTE 5 (EXPLAINED STEP BY STEP) IN ORDER TO MAKE MY PHONE WORK AGAIN????
I have never before messed with the phone.It has the original stock firmware Android 7.0 Nougat.
And the phone is bought in USA,but I live in EUROPE and have unlocked it ,by buying some code online, few years ago.It was working fine until yesterday.
Thank you in advance guys I hope that someone might help me.

Guys I found here some older version (few months older) of Android 7 for my Note 5 and I managed to do a flash. The flashing went OK I went through settings and after few minutes the phone freezes again and restarts. And then again the same,it works fine for a few minutes,freezes and restarts (I can here the camera working inside sometimes too)...........CAN ANYONE HELP ME REPAIR MY PHONE ,PLEASE ???
Hi again
I don't know why no one is replying to me???
Today I managed to make the settings and power up the phone,restored the back up....the phone is working,BUT the PROBLEM is that it constantly freezes and reboots by itself.Sometimes it works for few minutes and reboots,sometimes it works for 30min and then it reboots,sometimes longer...
What might be the problem? Is it some hardware problem processor ,memory or maybe bad battery? It is older model and I have noticed with Accu Battery that most likely the battery haslowered it's capacity.It drains faster,sometimes when it comes to 15% it drains very fast...
Can anyone help me diagnose the problem?
Thank you in advance
Try booting into Download Mode & flash a new stock firmware if all else fails, assuming u tried a factory reset first with no satisfaction. Guides are everywhere. I HTH

Thank you for your reply
I managed to flash the firmware few times,but the phone keeps freezing after some time and restarts.Sometimes it is stuck in the bootloop,sometimes it starts up to some point,freezes and restarts.
Could it be BAD BATTERY or is it something else?
If it is the battery problem,I will replace it,but I'm afraid that it might be someting else wrong.
What is your opinion?
