[Q] LG G3 Turning Off Problem

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

Boot Loop after one month

Here we go again...
Another LG phone having boot loops...
Bought from Best Buy on April 5TH with no protection...
May 6 phone started its random turn off....Have to do a battery pull and rest it for 10 minutes to get it to start up again..
After a min or two , it powers off again..
Yes, I was able to do soft and hard re-sets to no avail...
Just filed a repair request with LG...
Grrrrrrr
Mike

I had the same issue with Sprint LG G5. I bought it in April 13 the from Best Buy. It started to reboot 3 times at first and got real hot before it started rebooting. I took it to Sprint repair center where they suggested to do a factory reset. I told them I can do that. But before I was able to do a factory reset, it finally died. Sprint didn't want to replace the phone since I didn't have insurance. I might have to send it to LG for warranty repair which will take 9 business days. Do not buy the LG G5..

About a week and a half after I got my G5 it overheated really badly and turned itself off and wouldn't restart after attempting to reboot several times. I disconnected it from the power source let it cool off then plugged it in using the OEM power wart that came with the phone. That worked and the phone restarted. A week later the same happened. The phone overheated and attempted to restart several times and this time it seemed hotter than the first time. It turned itself off eventually and I was unable to turn it back on again. Less than three weeks into ownership and the phone was completely unresponsive and dead. I took it into the sprint dealership and they initially refused to replace the phone despite the fact it was under a month before this problem surfaced. They wanted to take the dead phone and have a new one shipped out to me. I told them that was unacceptable and they came up with the compromise that if I signed up for protection now they would backdate it and give me a new replacement phone. I took the deal with the full intention of canceling the protection plan within a month or two after I'm sure this new phone isn't going to be an issue. The new phone has been pretty solid for me so far. It gets warmer than I like but that may just be a product of hypersensitivity to heat after the first phone. That was the first time with any phone that I've ever had where a phone catastrophically failed on me like that. Sprint's response at the their shop was completely unacceptable given the time frame since purchase. I like the phone but I'm not liking how ownership of it is starting out. This was about two weeks ago now and I'm still gunshy with this phone afraid this new one is going to crash on me as well. I do not like that feeling. Thank God I have a backup phone just in case.

Goes to show phones these days are not built the same. I've had the g5 since day 1, not any of the problems I've read I've had since owning the phone. I got mine from a Sprint store also. Only issue I have is the slight lag I have when connecting to anything internet related. I believe that to be something kernel related.

Nexus 5x shut off and won't turn on

If I posted this in the incorrect place or there is something related to my issue, I apologize in advance.
I've been searching here and all over the internet and no progress yet so I decided to make a new account here just to see if anyone can help me because I'm out of ideas right now.
This morning my Nexus 5x (Non-rooted Nougat) woke me up like every morning, after dismissing the alarm I left it on my bed and when I came back to grab it later I noticed it shut off.
Here are the facts and what I have tried so far:
- Battery level was almost full
- I tried to turn it on but nothing happened, not even the Google logo
- Connected it to power and no icons or any response at all
- Left it connected for like an hour and tried to get it into recovery mode
- I was able to get into fastboot mode a few times but after electing "start" or "recovery mode" the Google logo comes up and then shuts off again right after.
- Tried getting into recovery mode after leaving it charging for a while again but I couldn't even get into fastboot this time, no signs of life at all.
- Disconnected the battery for a few minutes and tried to get into fastboot mode again, this time it worked but same thing happened. (Google logo then shuts off)
- Tried connecting it to my PC but doesn't show up on Linux nor Windows, on Windows it makes the sound like I connected a peripheral but that's pretty much it.
- I have USB debugging enable but never accessed my stuff through usb connection because I have had this issue before where it is connected but it won't show up or it shows up but won't let me access the files even though the phone is unlocked.
At this point it just won't do anything and I ran out of ideas. I just want to at least recover some pictures and information I have in it that isn't backed up, if anyone can help me I would greatly appreciate it.
Thanks in advance

It sounds like you might have encountered the hardware bootloop issue. This is theorized to be caused by bad solder for the eMMC chip or bad eMMC chip. This was an acknowledge problem on a related model LG phone, but hasn't been acknowledged for N5x.
If you are under warranty, you should start the replacement process before it runs out.
If you want to try something that sounds crazy but has worked for some people, put the phone in the freezer for 15 minutes then see if it boots. If it does, quickly back up as much data as you can, then wipe the phone in preparation to RMA exchange.

Just boot to bootloader (fastboot) then unlock it and flash a factory image... u can find many guides to this operation on the XDA

Same here... cannot enter recovery mode, so flashed new rom stock rom.
The flashing was fine but it didn't help.

guys if u can get to the bootloader, sure it can be fixed.. everything is possible with the fastboot, u can fix any issue. if it's a hardware issue the bootloader wouldn't work as well.

I've had the same problem with my 5X, except my alarm didn't even go off! I woke up 15 minutes late to see the boot screen "enter your pattern to start Android". I entered my pattern and it looked like it was going to boot up but when I went back to it it was blank. Tried again, got to the Google loading dots and it switched off again and I haven't been able to power it up since. No bootloader, nothing. Tried all the troubleshooting steps on the Nexus Google Support pages (I did post a link but because I'm new it won't show, so just Google "Nexus Support") and nothing worked. I also knew the battery was fully charged because it had been on charge overnight and when I did get to the 'enter your pattern' screen, the battery icon in the notification bar was full.
I requested a call back from Google and nothing happened so I tried the chat and they said it sounded like a hardware issue and are sending me a replacement device within the next 3-5 working days. Good that they're replacing it. Bad that it happened on a device less than a year old and they only offered £10 Play Store credit by way of compensation, when I've had to spend £15+ on a PAYG sim card to use in my old phone in the meantime because the nano sim in my 5X was too small and I've spent over an hour and half this afternoon wasting my time with troubleshooting and waiting for a call back... Not really the customer service I expected from Google for what appears to be a hardware issue. If you bought the phone from Google, my advice would be to get in touch with Google Support and they should replace it under warranty.

I contacted Google and they didn't help me at all because my warranty expired last month, they literally just told me to put in a repair request at the LG repair webpage....this sucks

My experience exactly...
My wife's Nexus 5 exhibited the exact same symptoms this morning. It's been running perfectly for 20 months and today it died, and we're unable to even get into the bootloader screen or power on the phone.
Taking your advice, we put it in the freezer for 15 minutes and were able to perform a factory reset wiping all data from the phone. We are going to take advantage of Google's Christmas 2017 promotion and return the Nexus 5X and buy a Moto 4X. They require you perform a factory reset before returning the phone in order to receive a credit for the returned Nexus 5. Thank you so much for the help!

I've just posted this thread overlooking yours. I think this is becoming another common issue. Has the freezer trick worked with anybody else?

I am having the same issue described here. My Nexus 5x went into a Bootloop about one month ago, but I was able to get it working again by going into Recovery Mode. About 4 days ago it went into a constant Bootloop, just showing the Google screen, and I couldnt get back in to recovery mode. I ordered a new phone on Tuesday (Pixel 2) and as long as I am able to do a factory reset I should get a $150 credit when I send this phone back. So, in desperation, I took a chance on the 15 minute freezer trick, and it worked! I was able to get into recovery mode (power + volume down, select Recovery Mode, little dude on his back came up, pushed power + volume up once) and cleared the cache and applied the factory reset. Ridiculous that this phone only lasted 18 months, but if I get the $150 credit I will be happy.

Same problem here -- just froze for a few seconds, powered off, and won't turn back on. Not a boot loop issue as there is no response at all from any buttons. Swapping the mainboard from a working phone powered up without a problem, but obviously that's the other phone's emmc.
I tried the freezer thing and it sort of worked- LCD powered on for a couple seconds, but then shut back off again and even that only happened once. That's progress over the usual absolutely no response though... Anyone have insight into why the temperature would matter? something is overheating that this gives a bit of wiggle room since it starts much colder than usual? maybe a more complex analog electronic situation?
I would happily pull the flash chip off and put it in a emmc reader, but I think I'm out of luck because from what I've read the dm-crypt key is generated from some data stored in in the processor's trust zone thing. I know the "password" but if that's only part of what makes the key and the rest isn't on the flash chip I suppose there's no point in going that route.
I don't care about the hardware surviving; mostly just looking to recover my data. Anyone have suggestions? Hardware debugging direction? I'm willing to buy some electronics test equipment (within reason of course; not picking up a 10000USD rework station for some old photos and contact list...)

The only way to connect that buddy to PC is to get SoC (CPU) working, so theoretically you can go towards reballing the chip. But I guess it's not an easy thing for such a little chip. Also u will need kinda plate for balls, i think there are no common ones, so u can make it yourself if have a technical education.
Another way is to connect memory right to PC without a phone but with some connector. IDK if there are any available, but this looks much more simple. I actually got the same happened, and tried to heat the plate, but with particular success.
IMHO

Here's the reader
https://www.amazon.com/ALLSOCKET-eMMC169-Programmer-Kingston-Interface/dp/B06Y55DKND/
But I assume the problem is I will not be able to generate the encryption key because part of it is in the processor.
If someone has tried this and it definitely works, I'll give it a go. Just don't want to buy the emmc reader and heat gun this chip off if it's certainly a waste of time.

I've seen a post of a guy who sent his motherboard to china and got reballed it and gained 4gb of ram. Can be wrong, but it was around $50 and a month of time.

Google Nexus 5X LG-H791 Bootstuck

Hi,
I got an issue last night with my Nexus 5X, he suddenly stopped without the possibility of restarting it.
The battery was 80% full and i never installed any rom on the phone.
It's not a bootloop because when i press power, google screen appears for 5-10 seconds then the phone shutdown again.
I tried to press power + volume -, but no option in the menu works.
I don't know what to do but to get in contact with the seller to make the warranty works, i get pissed for all the data on it :'(
Sorry for my bad english, it's not my mother tongue :crying:

Same issue

I am having the same issue as you, I even managed to flash the stock 7.1.2 and it worked for 10 minutes then it froze and went back to not working at all.
I have no idea how to fix this and I am out of warranty.

i got issue 15 minutes ago too, dont know why it stopped.
i suffing web and suddenly it turn off screen.
i do all thing i can but nothing work:crying::crying:
my devices is Google nexus LG H790

Mine died on me a couple months ago in this same way. I do believe this is the bootloop or hardware failure that is known for the LG phones at the time. The V10, G4 and Nexus 5X have all been effected by it. When it happened I did some searching online and saw a video of someone putting it in the freezer for a short time to cool the motherboard and it turned on for a limited time. It was long enough for me to back up the stuff I need before it shut off again. I was also able to wipe and factory reset it another time the same way. It's been harder to get it to turn on lately. A better fix I saw (although temporary as well) was taking the motherboard out and using a heat gun to reconnect the solder. That is what I believe the issue is. But I haven't gone that route.

oh my.. it happened to me yesterday, now i see this... i flashed a new recovery and nothing, it passes the google screen to black.
Ill try the freezer thing to see what happens

Hello,
Thank you all for your answers & testimony ^^ , how long did you put it in the freezer?
This manipulation can kill the warranty ?

i had it like 20 miutes and it worked a few minutes, now im trying longer...
as for the warranty, i dont think it has anything to do... its like when u go to the mountains or if u live i a really cold country :lol:

This is how my phone acted before it eventually boot looped. Letting it sit in the freezer for a while would get it to go into the recovery menu, but it would not enter recovery or boot. The only way I got it to actually boot was using a hair dryer on the motherboard. But it immediately froze once unlocked. It also bootlooped. I got it to boot for a long period only by using a heat gun on the motherboard. Second time around I used a higher setting and it acted normal for 9 hours. But then it rebooted on its own and eventually bootlooped again.
A video In Spanish, but good walk through and you can just follow the video with subtitles.

I only put it in there for maybe 5 to 10 minutes. The longer it's in there the more condensation builds up on it. This is the video I watched that gave me the idea. He talks about it in the beginning. So I just tried it.

My Nexus 5x got the bootloop yesterday, can't fix it by myself.

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.

That was my first idea, but i don't wan't to use any money for this phone
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
