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
I haven't been on here for quite some time and wanted to know if others with this phone have been able to get something different (possibly V10) from LG. This morning I was looking at a media intensive web page and the phone froze (has done this many times) then rebooted. After the LG splash screen it just died despite having 44% battery. After this it would not recognize being charged and would not power on. If I let it sit long enough and remove and replace the battery it will show the LG splash screen then die again.
I'm asking the question about switching devices because there has been nothing but problems from touch screen misses, to the QC 808 heating up like an oven, now the bootloop issue. I've always came to XDA to mod an already perfectly working phone. I am now feeling like I'll have to start modding my phone just to get it to work right. I am thinking of reaching out to LG to try see if they are giving any options to us.
The same thing happened to me this morning, was looking at a video on Facebook when it suddenly froze up! Did not respond to anything... Had to pull the battery but now it does not respond to anything, had 90% battery!... After doing what You wrote, waiting a while and then put the battery back in it started up, but it stays on the LG logo for aprox a minute, before it just goes black again!? Did You find a solution? It is under a year old, so I presume this is a reclamation from LG? I have never had any issues with it like oveheating etc etc, only thing was a dead pixel on the screen when I bought it, but got a replacement screen without any problems from the service provider, so the sevice and time used was great, really hope that it is going that smoot this time too.... But seems like there are a lot of issues with the G4.... my wifes G4 has has the problems with overheating and battery drain, but mine has worked great, until now ?

Check your S/N. If that starts with anything between 505 and 509... welcome to the club.
That's a well know issue with logic board on those batches causing the board to die and requiring replacement.
I am in the club, It starts with 505 ?? i tought it was the bootloop issue on those numbers, did not know there was a issue with the motherboards before I started googleing.. And I did not know it replyed the 505-509 batch, so thanks for the info? so if it is a known case for LG and their repair services, it should not be any discussion about replacing it ?

He's guessing.
Just to be completely clear:
There has been no official confirmation from LG or any official source of what devices are affected and what causes the issues.
Anybody saying it's 505's only, 505-509 are only speculating and have no official information.
LG have stated that the bootloop is covered for another 3 months outside the standard 12 month warranty.
I am in Rochester and was looking for like minded friends.
I recently relocated back to Rochester from China after being away for 8 years.
I have a Xiaomi Max 128gb that was working fine for about 45 days after arriving.
It then did an OTA update from Xiaomi then the touch screen stopped responding.
Since then I have tried to do Full Factory Reinstall, zip flash, tgz flash and non resolved the touch screen functionality issue.
Since then the battery drained and the screen no longer turns on. I am trying to find a way to do a diagnostic of the hardware without the screen working and possibly find an OEM replacement screen or a service center. . .
Do you know of anyone that maybe able to help locally?
Here is my update on this issue.
I just bought an OEM replacement screen and digitizer. I completed the test to see if the new one works it does not boot up or power on. I wonder if it is a motherboard or battery issue now.
Is there any way to test and determine where the fault is located?
Hello
My Nexus 5x 16 GB (LG H791 ) got the bootloop, i need to fix my phone !
Soo yesterday was a very hot day.
I ran around a bit outside and took a lot of pictures. But it was very hot outside. Whenever I take pictures, HDR has to be rendered first, it consumes a lot of power and I can imagine that the Nexus 5x gets hot. When I put it in my pocket, it still worked. After I got it out again, the screen was completely black and it could not boot anymore. It was just black, nothing worked.
Later, I went home to look at the Nexus 5x.
I looked at whether it was possible to get into fastmode, dloadmode and recoverymode, but the screen remained black.
I've fixed other cell phones before, but with the Nexus 5x, I still have some little hopes.
I opened the nexus and cleaned it completely with 100% alcohol. Every corner and every connector.
After cleaning I switched it on again and suddenly it started again.
But it only showed the colorful google animation and it restarted after a short time and it repeated itself endlessly.
From there I noticed that it is the well-known bootloop problem.
I knew before that it will eventually come to this problem, so I unlocked my OEM (Bootloader) about 1 year ago :good: !
So I googled and there seem to be some fixes !?
First of all, I tried THIS and it didn't help
I tried also from this solution the TWRP recovery. Jeah i got in to the TWRP recovery and installed the EX4_10_5X.zip, but with some errors. The Nexus is still repeating... BUT!! The google logo animation was stuck, no animation!
Soo I googled more and more and saw a new solution!
THIS! So i did all 4 stepts expect step 1, because it's already unlocked.
JEAH! My Nexus 5x seems to be ok again ! After I set everything up, the Nexus 5x has frozen and crashed ! Man damn!! I was sooo happy..
Then i tried to flash the latest factory image from https://developers.google.com/android/images?hl=en#bullhead
I ran the "flash-all.bat", got no problems the first time, but the Nexus is still bootlooping :/
So i flashed it again with a factory image from 8.1.0 (OPM1.171019.011, Dec 2017).
But this time the Nexus has freezed and turned off!
It restarted by itself, but there was no Google logo anymore. It restarted each time after the message came that the Nexus is unlocked.
If I go into fast mode, it freezes after a short time, it is not possible to flash an image on it, because after a "fastboot reboot-bootloader" command, the Nexus just stops responding, so I have to disconnect the battery.
If I reconnect the battery immediately, the screen will still be black.
So I always have to wait 3 minutes until I can connect the battery again. This is exactly as with a USB-C cable.
I got one time a crash or greenscreen !
I saw a thread about (BLOD).
I downloaded the latest fix files. After i got really quick into the fastboot mode, i flashed this two things and jeah i got my google logo back, but it still freezes and it won't turn on, only if I reconnect the battery after some minutes.
Now my problems:
No Google logo (Rare)
It stays off after it freezes
It's hard and randomly that I get into the recovery mode with TWRP. If I make it, the nexus freezes again
I can not flash an image because the screen stays black every time I restart
I can't fix it, i need your help ! Pls
Community ? Can you help me ?
@MrClean24, I'd say goodbye: even if you succeed to make it run with sleeping cores, it's slow and wont be stable.

If it can't be fixed, then i will buy a Pixel 3a phone.
@MrClean24, good idea (I'm not favouring bin generally, but you wont fix damaged hardware by software plasters durably)
Jeah its a hardware problem :/ I think mine can't be fixed anymore, but thanks

Hi everyone, the phone was working fine, it was left to do an update for 3:00 in the morning. Couple hours later realized phone was blank/ black screen. Followed steps to do power and volume down and all it did was vibrate. It vibrates when plugged in. Two technicians looked at it and said it was a screen problem but a new screen was tried and it only showed a charging sign and after that it went blank again. I am wondering if it was android update that breaked the phone or is it something else. What specific hardware failure or is this software failure?
Any help would be greatly appreciated. Thank you.
My cousin had a similar issue with a black screen when they woke up - however their phone automatically reset itself and lost all data while updated to Android 13 overnight.

tried a firmware reflash?
anyways yes. samsung is a **** and has given me terrible experience with my a32. they dont pay attention to midrangers at all pushing out broken ota updates. My fingerprint sensor is now bricked permanently (no like actually. downgrading firmware doesnt help. its just gone. its fine physically. according to logs but something else broke ig). Then that stupid mobile data bug. where if i was using mobile data jt would disconnect from the cell towers and reconnect. as if there was no service. i saw many people have this issue. I was forced to use a gsi. One ui 5.0 is still pretty terrible for this thing. its not optimized at all. I am waiting for one ui 5.1. the final big update for this phone. Samsung seems to be pushing it out for all the phones. even cheaper than this phone. but looks like they forgot abt it.
