I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.
The problem started by every now and then (sometimes not happening for a day at a time) the phone would turn off then turn back on again gradually getting worse. The problem started when I installed the latest update during the update the screen froze (no it was not interrupted in anyway and done officially through the phone) so after leaving it overnight and it not progressing I took the chance and removed the battery. it then turned on and finished the update without an issue. The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

Maybe it's a hardware issue
hi, where did you get the firmware? it could be corrupted. if I were you I would download again the firmware and reflash it.
after that I'll do a hard reset.

Well i guess im not alone as i have the same exact problem as you do! WHich version do you have? I have the White T-Mobile version and i bought it the same week it was on sale i felt that i got a phone that was part of a bad batch because of some problems ive had with it but i didnt buy insurance for it. i was on LG's OS and it started to get worse and worse so i restored it and went to a lollipop rom. its still happening but it only reboots once. however, as soon as i start using apps it reboots on me. i want to unroot it but at the same time i dont want to go through the trouble of rooting it again. Any ideas of what it could be?
My problem just randomly started happening and i noticed this started happening strangely after my phone completely died on me and didnt want to turn on so i connected it to the charger and it started charging but had a yellow warning triangle somewhere on the screen.

Hey, nice to hear someone has the same issue, I however hvent had the yellow warning triangle come up yet, as an update all of a sudden it keeps turning off as soon as it boots even on charge!!!??? It just keeps getting gradually worse?! However I have noticed the battery % it shows when turned off is 100% and very randomly it displays 70% then when the phone boots it will show 2% for the 2 seconds it stays on before it dies?!

Wait now it reboots on you even if its charging? I too started noticing that with my battery . if I turn it off and charge it it and lets say it says its at 75% well I turn it on and its like at 40%? I really don't want to buy another battery but I actually hope the battery is the culprit. There's a guy with a G3 in my school I'm going to see if he let's me try his battery out on my phone I'll keep you posted

Hey sorry for taking so damn long on replying i've been busy studying for some exams.
I've got good news for you though, i took my phone in to T-Mobile and showed them my problem. Without me putting much effort into persuading them, they shipped me a new phone, and no i didn't pay for insurance on T-Mobile, this was covered by LG's 1 year Manufacturers warranty!
Anyways, I received the device but did not receive a battery. So i tried my battery on the new one and what do you know? SAME PROBLEM!
So yea you should either try to unroot the phone and take it to the store but don't mention that you think its the battery, they'll send you a new phone! Then just buy a battery online or call them after a few days and say your problem is still occurring with the new phone and see if they send you a replacement battery, im a little skeptical on this second option as id rather keep this new phone haha

Hi, even i am having this problem, my phone is a D855 and in my country (Mozambique) i am not using a contract so its different than US, we have a LG store here but in the LG website our country is not stated. So only way is to go to a trusted Store that repairs phone here. My question is that, when its not connected in the charger it just keeps reboting (the notification LED doesnt even blink) infinite times. At first i thought it was a software but after going from Stock to Cloudy to CandyRom the problem was still there. Then after i plugged in a charger the phone would succesfully boot up and i could use it normally but had to stay connected on a charger. So what have you done to fix this? Did you replace the battery with a new one and then it stopped rebooting?? Please help me as i want to buy a new battery but first want to confirm if its the battery at fault....

Hello buddy, sorry for taking so long to reply. Im usually not on XDA too much. Yes i solved my issue with a new battery. I tried my bad battery on 2 lg g3s and it rebooted both. I also unrooted my phone and flashed a completely stock update and was still having that issue.
I hope my response isnt too late for you!
No problem bro! Got a new battery and do far my phone doesnt reboot, but the only problem i am having is that my phone shutsdown at 30% battery and when trying to turn on it says it has 0%

Im having the same problem gotba new battery and no different so annoying
Best thing just happened. I had the G3 for a while and my first one had an issue and had to get a warranty replacement. Long story short... I got two more G3s from T-Mobile that were defective and most carries have a policy where if you get 3 warranty replacements you can chose a different phone. To wrap it up, you can ask for a phone of equal or lesser value when purchased from the carrier (I bought mine off eBay and they didn't even notice, I spoke to several reps and no one caught on.) So they can either send you a whole new phone, a new battery, or in my case: I received a new LG G4 since I had gone through three which pretty much anyone can do with a bad battery.
Guys. Im having this same exact problem on my LGG3!!!
Expired Battery or Faulty Power Button could be the culprit
This issue just started happening to my LG G3 over the last 2 weeks. I've had my LG G3 for exactly 15 months and all of a sudden it started cycling endlessly and if it did get to my locked screen and i tried to unlock it it would just restart again.
I found that when I plugged in the device to a wall charger or high power power brick, it would halt the reboots but otherwise it would get stuck in an endless cycle of partial reboots (when it did stop after plugging in, I would find all my apps still open and waiting for me, so they weren't real power cycles).
One of my coworkers has a newer LG G3, so we swapped batteries and immediately he had the cycling issue on his phone and with his battery in my phone the issue vanished.
On closer inspection, my battery was a few months past its expiration (FYI to anyone with a LG G3 - your battery will expire more or less exactly as its warranty protection does!), so went and bought a new battery and everything is fine now.
For those of you who have tried replacing the battery and find it still occurs, another coworker said his wife had a similar issue on a different device and it was resolved by having the power button replaced, so it is possible that this could be a factor also and you should have your phone sent in for inspection/repair.
Hope this is helpful for some of you.

I've had the same issue since February, when my phone was about 17 months old. It kept turning off saying SIM card not detected. I tried replacing the SIM card and washing that area with alcohol with no luck. Then I replaced the battery with a second one that came with the phone which I'd never used, but I noticed no difference. It also has no phone service for several hours without my knowledge. LG just told me to reset the phone, but it looks like that doesn't work from what I've read. T-Mobile said they'd give me a new phone but there are no G3s in stock and offered me a Samsung 3, which is three years old, so I am worried that it won't be able to handle the software updates. It's ridiculous that a phone that costs this much won't even last long enough for me to pay it off. My last phone was an Iphone, which I had for more than four years.
I had the exact same problem a few weeks ago, posted a detailed explanation of the problem and got 0 replies and a few hundred views (thanks guys!)
Easy answer:
Replace your battery
Thats what I did, and the problem is now gone. When you do get a new battery make sure you drain it completely first, then charge it for 4 hours without exceptions.
I tried factory resetting, installing a new firmware, going to stock and going to custom but nothing worked.
The girl in the shop where i bought the battery surprised me, i just asked her if they had one available and her immediate reply way "why, is your g3 stuck in a boot loop?", apparently EVERY SINGLE PERSON that bought a g3 battery from them had the exact same issue.
Now the problem is gone, and my phone actually lasts longer than before.

Hey, I am having the EXACT same issue. LG G3 was stuck in an endless loop, replaced the battery, now it works down to about 30% and shuts off. When I try to restart it says 0%. I even tried a third different battery, and still getting that 30% shutdown. Did you ever figure out what it was? I am wondering is it something to do with how the phone reads the battery charge i.e. does it think the battery is dead when it gets to 30%? It has e stumped!! Any advice would be most welcome. Thanks.
wtf,actually same with my LG G3,after when I bought a new battery. Shutsdown at 30% and it says has 0%.
same problem

I HAVE THE SAME PROBLEM help PLEAAAAASE
Hi guys, I really need the power of the internet now. My googling powers have let me down, and now there's only you guys left to help me!!
I got a Lg g3, and i've enjoyed it for a while. I have experiemented a little with it (rooting and installing roms) and it's about 2 years old i think.
And now, the wierdest problem that I really can't understand, i'll try to explain as good as i can!
It all started a couple of days ago, my phone just rebooted as soon as I started up Snapchat. After a day, this reboot appeared more frequently, and yesterday I gave up. The thing is, as long as it's charging, it works fine, all of the programs. But when I woke up this morning, it's completely ruined.... i see the LG startup screen, and then the lock screen. As soon as i touch the screen, it restarts again!
I've tried factory reset and wiping data and stuff.... If any more information is required, i'll provide it as soon as possible!
I believe in you guys, help me out!
I thought about overheating, but since it works while charging, i ruled that out, right?

So, your phone its ok while on charging right?
Guess it's time to buy a new battery...
Sent from my LG-D855 using Tapatalk
u sure it's the battery? cause it works a bit better right now. How can i check if it's the battery that's the flaw? it's so wierd that it just got more and more random reboots....
That sounds like the battery as it was the expect problem I had 6 months ago with a battery that was about the same age as yours. I found that my battery had started to swell, very big problem with lithium batteries when they go bad. If you take your battery out and look at it side on there should be no bulging anywhere on the battery, if you see any bulging then stop using it until you can get a replacement.
At the time my phone would work fine when plugged in but would constantly reboot when on battery power.
It seems like that's not the problem, right now it's working fine. I checked the battery and no swellings at all! Could there be any other reason for my phone to act out the way it did/does sometime still?
Did the rebooting start at a particular battery level? Reason I ask is that my spare battery is now showing the same symptoms, but only when lower than 55%, phone will reboot and immediately be at 15%. I pulled the battery out and could feel slight raises along it, not enough to see but I could feel it when compared to my other battery.

Dear Taynor, Try flashing stock firmware of your device. If you suspect your device battery, then first replace it and check whether rebooting issue is still there. Otherwise, flashing stock firmware resolve many issues. Use kdz with LG Flash tool 2014. It is easy to flash firmwares with LG Flash Tool 2014.
Last week I have rooted my LG G3 so I can install Cyanogenmod 13 on it, bcs after some time I felt my phone got slow and the battery life was not that great. I installed it and it got really better. I tried to get a more stock feel so I installed Xposed and the module Android N-ify to get some Android N look to it. Like always, it said my phone can get into a boot loop, but I knew how to fix it. So, one morning I woke up and saw my phone in the reboot screen and didn't care a lot about it. Later I woke up to get ready to go to my lectures, but the LG logo was still there on my screen. It would then get black and the logo reapears. I thought it got into a bootloop and reflashed CM, but still. I wiped the whole system, reinstalled it again, nothing. Flashed stock Firmware to it, still the same. I brought the phone to the workshop where I work and a coworker took care of it, saying he installed the softwer anew and it really looked like it was fixed. I got home, plugged it into the charger and when I got back it was like before, restarting... It didn't look like it was software based so I searched the forums and saw that a lot of similar problems were solved with buying a new battery. I did the same but it got even worse... Before I could actually sometimes get pass the bootloop but WiFi, Bluetooth and the other connectivities wouldn't work, now it just keeps bootlooping. A friend of me, who works at a repair service, said I should buy a new "power flex" for the phone and install it. I bought it, but I am not sure if it will fix it. It should arrive sometime next week, but I wanted still to ask here if somebody has somekind of idea that could help me. And yes, I tried also to put a piece of paper between the battery and the simtray, but didn't help me... Would the problem be solved if installed the power flex? And did this happen bcs I rooted my phone?
Hey everyone... I was using my phone as usual when suddenly it blue screened and died on me. Like dieded died. I've been soft bricked before but this was bad. It wouldn't on after taking out the battery, charging, different batteries (anker)
Left it for a while tried again, nothing. Like not even the boot up animation. Now, the phone had been acting up for the past 2 days. Random reboots every few hours and it even blue screened the day b4 but came back as usual. I was just considering a new rom cos i had been on this one a while so i thought maybe it was just time for a new flash when all this happened. Full disclosure im rooted xposed on Dirty Unicorns Marshmallow. Also not sure if this is relevant but i had recently begun using new batteries from anker for the past 2 months
That's the only new thing i did to my phone. I use my phone to just below 5%, off then pop a new 100% battery in. I hadn't charged my phone my cable since.
I went to a repair shop immediately and they tried hooking it up directly to a positive negative power source but they said it wasnt registering at all, so im thinking this is serious.. I Googled around and best i could find was that this maybe a motherboard issue. The only solution ive found online (https://forum.xda-developers.com/lg-g3/help/lg-g3-d855-blue-screen-death-t3380844) were those saying i need to bake\heat the motherboard?? At first i thought it was a troll but im desperate and not sure anymore
Is that a legit solution and if not, what is...? Please guys i can't afford a new phone for at least another year. Thanks in advance.
