Same problem with CM 12.1

I had my D855 with stock firmware (4.4.4) and I had the random shutdowns, I had to take off the battery to reboot the phone. I decided to install CM to try to fix it: I installed fastboot, then with bump TWRP I installed CM 12.1 (Android 5.1.1 with Linux 3.4.0 and PICO GAPPS)...

Result: Still the random shutdowns, but now I don't have to take the off the battery. I noticed that the "up time" doesn't reset after it.

After reading the comments that with Airplane Mode the phone won't shut down I read the aLogcat and found:

W/Settings(31405): Setting airplane_mode_on has moved from android.provider.Settings.System to android.provider.Settings.Global, returning read-only value.

This error is persistent, however after some research, I found that it should not cause the reboots:

E/QCOM PowerHAL(31145): Failed to acquire lock.

I put the aLogcat Fatal after the reboot:

http://pastebin.com/0a1sicPW

I have the full aLogcat and bugreport in case someone would like to take a look.
[G3 Q&A, Help & Troubleshooting] P3lUZa:
More research on CM

After more research I found that it may be a different type of shutdown, since with stock 4.4.4 I had to remove the battery to fully reboot the phone, while with CM 12.1 it is not required to remove the battery, and the phone doesn't turn off totally (No LG logo, just CM logo), and the uptime is not affected.

So, as stated in the CM forum http://forum.cyanogenmod.org/topic/114342-lg-d855-unexpected-shut-downs/#entry542915 it may be caused by problems with strictmode (other problems maybe related to a faulty battery)

To dissable strict mode:

$ adb shell

$ su

$ setprop persist.sys.strictmode.disable true

$ reboot

Hope it helps

My phone can only boot to homescreen with battery level below <= 5%

idk why .. even replacement of the battery with another brand, it doesn't solve the problem, but it boots with battery level below <=5% till homescreen, but got freeze again

that's weird

even connected to wall charger it had bootloop, but when i connected to wall charger with batt level below <=5% , it was charging. Batt level below <=5% solve half of the problem

for those who have also got the random shutdown problem and get worse and become bootloop, try using batt with batt level below <5%

My 32GB D855 has this problem!

It all started about a week ago, i did some app updates and some xposed updates, naturally i thought it was these updates so I disabled all my xposed modules, it works a bit better now, the random reboots are less frequent but they still happen! Especially if i open snapchat, even with all my xposed modules disabled.

I'm going to try flashing another rom now, and starting from scratch.

I wish this stupid phone would just work properly.
[G3 Q&A, Help & Troubleshooting] ScAvEnGeR(PHC):
Update:

After 10 months with a D851, I've changed 3 batteries, the phone reacts differently to all of them, shutting down at 60% for one battery, 40% for the other, 75% for the third.

I've seen that it doesn't shutdown on its own while airplane mode is on.

I've reflashed the software etc, it's no use.

I have experienced that when in areas of full cell reception, the phone doesn't shutdown on its on at all, but in areas of poor cell phone reception it turns off rapidly with and without wifi usage.

I have this problem also i have tried factory restoring it several times but still only works when the phone is on charge. My phone has run out of warranty. There must be a way of fixing it without having to pay to get it fixed. I thought maybe it was an update that caused this problem so i didnt install any updates and it still has the same problem. has anyone got any other suggestion? I havent seen any other suggestions other than a factory restore which doesnt work.

I have same problem. I use G3 about 2,5 years, it was perfect phone, but now I can use it only with cable... WTH?

Looks like LG don't care about millions of people with LG G3 same problem
[G3 Q&A, Help & Troubleshooting] S.AMU:
My phone also started to have this problem now. 3 months ago the phone only shutted down once each month.

Now its three times a week. :(

I will start do do some tests now, because most of the shutdown where only when the phone had to wake up from "doing nothing" while it was charging wirelessly.
[G3 Q&A, Help & Troubleshooting] :
I put hours of time to fix this issue mate. No fix... I just have a suggestion for you. Don't buy LG anymore. I am switching to huawei myself. There are many people out there struggling with the same problem and LG doesn't give a sh*t. It's my 3rd LG phone but it's only getting worse and worse.
[G3 Q&A, Help & Troubleshooting] S.AMU:
Its my first LG phone :D I had Samsung bevore. But this phone has to live for the next 1.5 years minimum.

My phone is only 8months old. What do you think: should I try to replace it under warranty?

And did it really help someone to change the battery? I read the last 50 pages here, and no one really said if it was helping or not.
[G3 Q&A, Help & Troubleshooting] :
My own experience: very small effect during the first two weeks of the battery replacement. But the whole issue is a pain in the neck if not somewhere else. I'm out, I have 15 percent of battery and god I need GPS to find my way ! but my phone decides to shut down and begin a bootloop. If it's still under warranty , definitely go for it. Try to learn how to reproduce the issue (which is not so hard!) and take it there. Don't wait even for a second. Act today.
[G3 Q&A, Help & Troubleshooting] S.AMU:
Never had any problem when the battery is low. I think.its more.when.the battery is nearly full.

Finally (see above) I send my phone for warranty.

I installed V30c before I send it to LG and I got it back with V30c and a notice that they made a software update...

Could it be possible that they updated the firmware of something else in the phone or are they just kidding at me saying they made a software update?
[G3 Q&A, Help & Troubleshooting] Niurkt:
So software update help for phone? Or still same problem?

[G3 Q&A, Help & Troubleshooting] ScAvEnGeR(PHC):
It's a hardware issue, you can't do anything about it.

I thought of replacing mine with a G4 but the G4 completely dies on its own, can't fix it, LG is all f***** up. I suggest you replace this phone asap. And stay away from LG in the future.

Boot up!

Boot up! Finally my LG G3 come back to live !

Last time i got my G3 with heavy random reboot problem ...

I got other 2 new battery, V**z double power battery(some of my indonesian friends got it fixed, so i try to buy one, but i still got the problem) and the other one is LG(i think its the fake one) battery

All the battery got random reboot, i tried factory reset, change the sim card(insert it or not), the sd card, let it random reboot till phone become very very very hot stil didn't fix the reboot.

Maybe i have done nearly 10 times factory reset and it didn't work. Sometimes idk why it boots up to homescreen at certain percentage, sometimes when battery at <69%, sometime at <15%, sometime below at <5% ...

Connect to wall charger didn't work

Sometime it didn't show blink when boot up and directly reboot again

Sometime it show blink and when to homescreen, it freeze and reboot again

After a few week, i turn on my phone again, the problem still there, but i luckily got my phone boot up, and i thought maybe it's the memory problem? i tried recording the video until 20 minutes, and it sized about 1,8GB and record more. Reboot still there

Until then i thought maybe it was the kernel that detecting something wrong from battery and send signal to reboot? i start to root my phone when it luckily boot up at certain percentage of batt. Root, delete battery.bin file, change rom, change so many kernel, random reboot still there.

I tried debugging using adb, and then i found out error at thermal thing.

Tried "Fullmics Rom" , go to Fullmics Tweaks, go to "ADVANCED", go to "Hidden Menu", go to "Power", go to "High Temperature Property", and Enabled the "High Temp Prop OFF". Still reboot.

Try again "Fullmics Rom", go to Fullmics Tweaks again , go to "ADVANCED", go to "Hidden Menu", go to "Power", go to "BypassBooting" menu, turn on Battery Fake Mode to On, and try to reboot. Guess what, tadaa i see something positive .. My phone boot up directly! Showing led blink! Till homescreen! No random reboot again for a quite long time!

Try to reboot again, and it boot again! But the battery level on the phone showing 80% battery, no matter what, no matter you charge it still 80%, no matter it run out battery, it show 80%, good

I try again my first 2 other battery, it boot up till homescreen !

So the step is

1. Root your G3 (Read all instruction carefully)

2. Install TWRP using AutoRec (Read all instruction carefully)

3. Download Fullmics Rom 5.1 and OTA 5.1-5.2

4. Install the Rom!

5. Go to "Fullmics Tweaks" app, go to "ADVANCED" menu, go to "Hidden Menu", go to "Power", go to "BypassBooting", turn On "Battery Fake Mode"

Maybe you can directly go to "Hidden Menu" using some dial number like example. *1231#*123# at whatever rom and turn on Battery fake mode".

My solution

Yo guys,

Same problem. Bought phone in 2014. Around 10 months later the schutdowns started once a month, later 10 times a day. Got warranty and they give me a new phone. Again something like 10 months later i got the same ****.

Phone works well when being charged, but when on its own it reboots or turns off when running power consuming apps like the camera﻿, ...

Solution:

If your phone battery part number is EAC62378705 or EAC62378905, EAC62378701 (or maybe more) you might fix it by getting a new battery.

Do

NOT

buy the LG G3 original battery. Look around for a good replacement battery. No more shutdowns.

Only problem are wrong battery percentages, charging too 89% and empty battery when phone say like 30%. Im non rooted so i did a factory reset to be sure the old battery stats are deleted. Worked for me.

When rooted you can delete the battery stats without a factory reset. Maybe this works also.

Now i have my LGG3 running marshmallow with a 3200mAh replacement battery without any problems. :good:

has anyone figured out why the phone will shut off and not turn back on without pulling the battery? this is happening on the d850 phone is it a hardware issue or software? sorry if its been addressed
[G3 Q&A, Help & Troubleshooting] justinmartin111:
My D851 has the same issue. Some times it went off while in use ,somtimes when idle. Some times with full battery some times almost empty battery. I cannot find the reason of swith off.

I think it is related to battery or power because when turn on (only after connecting charger) it reads battery is zero(not every time) even if it died with 80% battery. Also there is a big difference in battery percentage before and after power off. I tried several roms including stock kk, mm, fulmics ,turbo etc all have the same problem repeating. I like the fulmics rom most so my g3 running now in fulmics withs itsown kernal.

I will try to take a log so that what is happening exactly before its death. I heared about a program called eclipse which can take log before swithoff(when connected to laptop in debugging mode).
[G3 Q&A, Help & Troubleshooting] reggjoo:
This phone has big problems, that seems to have no concrete solutions. I think it's a quality control issue. LG needs to step up their game with that. Yes, the phones designed right, has competitive main hardware components, but you have to have quality assembly, and testing on products people are going to buy. Lg's quality isn't good. I got my G3, from a friend , that was officially updated to Marsmallow. It randomly rebooted twice, for no reason, but it happened in the space of three weeks, so I wasn't really concerned. I went ahead , and downgraded(using LGUP), rooted, installed twrp, put cm12.1 on it(never could get my external card to work, but that's another thing that some post say are hardware related). It got very warm around the button/camera module(even with stock marsmallow). I thought I could put cm13 nightly on it, and it worked perfectly, for two days. went to the store in midday, of third day, came home, and phone, I thought, had turned off. Went to power it back on, but found out, it wasn't really off, just non-responsive(screen off, any pressing of power button did nothing). Had to pull battery, wait at least 10 seconds, to put it back in, couldn't turn it back on any other way. Messing around with twrp, I finally got it to fully load xneon rom(marshmallow). After loading, it will stay on for up to 30 seconds, then screen goes, unresponsive again. I've had many phones before, and none messed up this way(alcatel was a *****, with wrong posted usb drivers, for my model, after checking with my linux distro). Lg has quality control issues(just went to best buy and out of the three g5's they had on display, only one didn't have the module gap). Ordered a huawei 5x, I will put the G3 with my old phone museum.

Change the battery.. That solved my problem...
[G3 Q&A, Help & Troubleshooting] Simone98RC:
Absolutely agree with you.

Why haven't you spoken of LG G4? A perfect device that's affected by bootloops.

Every device, with every hw revision.

Warranty solve for a while, because the new device is affected too!

LG won't to admit its mistakes, I would spend €100 over if they guarantee me a longer life cycle.

Damn, I love LG, but it won't to be trustable!

Returning on LG G3, you should know that's the CPU reaching 90 °C to cause unwanted shutdowns.

Another unforgivable problem: device would stay on 80 °C when under stress in summer period, however may happens (even in normal usage) that temperature jump to 90 °C without any reason, so device put off.

The only thing we can do, is the applying of thermal paste with much attention.

Personally I would attend for a newer and cooler device.

LG G3 shuts down every 30 seconds

I was facing blue dead screen on my LG G3 D855 while starting the phone, Phone was not able to start at all.

Then I went to LG service center, They said that, Motherboard has to be replaced. There is no other solution. I came back home, and Googled and found one trick to bake motherboard in oven for 10 mins. (I took that risk as I have nothing to loose. )

I did the same and it worked, Phone started successfully and all my data are safe. :)

But now I found new issue: It shuts down automatically every 30 seconds with error message: "Invalid Battery Shutting down". Tried to open in safe mode and found same behavior.

Also tried to insert a fresh LG G3 battery but found the same issue.

Could anyone tell me is there any way I can take the backup of this phone when it can not remain up more than 30 seconds. ? So i can take the backup of my data and give any local mechanic to play around. As every mechanic is asking to hard reset first before proceed further to repair.

Thanks,

I got my G3 a week ago and it shut down three times.

1. Phone in my pocket, so I thought maybe I powered it off accidentally.

2. The phone lay unused on my desk, wasn't using it for about 30 minutes.

3. Tonight, phone was fully charged, so I plugged it off. Changed to flight mode and layed it down next to me. This morning I didn't hear the alarm and noticed, it was off again.

I don't think it is an hardware issue. Maybe it has something to do with the deep sleep of the phone. Only one time I had to take out the battery to power it up again.
[G3 Q&A, Help & Troubleshooting] turt:
Not everyone has had the phone for more than a week, and an affected phone may function normally for more than a week so it may still be possible. Furthermore we don't know what the root cause is, it may be a different parameter set by the user, or it may be network specific, or, or...

So it's too early to dismiss software issue.
[G3 Q&A, Help & Troubleshooting] SperVaxjo:
So i also tal med with LG support. And also he stated this is a software issue. They are working on a fix.

I know that with Telia in Sweden there was some kind of bug that was caused by bloatware from the network provider.

But this issue needs to be fixed asap.
[G3 Q&A, Help & Troubleshooting] McBeary:
The reason, why I don't think it is a hardware issue is, I used the phone constantly over the weekend and had no problems at all. I would suspect it to shut down because of overheating etc., but not because it is bored out ;)

If it is a hardware issue, I have the warranty. If I change it, the possibility of getting a phone with other issues are there and because it runs smooth, doesn't overheat or anything, I'll wait for a possible fix.

And maybe I'll do a factory reset, just to see if it helps.
[G3 Q&A, Help & Troubleshooting] butcher0:
I guess it is feasable that it can be a software issue.. Too bad that LG said I should return the phone if that is true.. 2 weeks without the phone in the holidays because of a software issue is kind of crap.
[G3 Q&A, Help & Troubleshooting] Dredd90:
So if it is a software issue why I have problems and a friend of mine doesn't have any at all for straight 10 days till now and we both have bought our G3s from the same store and both the phones have the exact same software information when you check it in the settings.

For me personaly it can't be software version otherwise the issue would occure on his phone as well becouse they are all the same.

And some other thing, do you notice that this only occures on D855(but not on all) and not on the other versions.

I am a programmer and I have to say that something is fishy if this is a software issue.. I do not exclude it, but one would think it was easier to reproduce if that was the case.. And also more users should have the issues by now. It seems to happen very very random. Nevertheless, I think it is fair for everybody having these issues to return their phones, that way if it is a software/firmware issue LG can do something about it.. If it is not then hey, you get a new phone without issues

I studied IT (magistrate degree) and I work in IT as a programmer, and when you have two exact the same builds of softwere on 2 devices, and those devices have almost identical apps and use the same carrier, and one of those has issues from the first 24 hours of use and the other works 10 day now with 0 problems, somehow its seems very doubtful to be a software issue. And since there are complaints just from the users with D855 version I am almost certein of a hardwere issue.
[G3 Q&A, Help & Troubleshooting] butcher0:
You can't really rely on a phone that shuts down randomly, sucks when you use it as an alarm clock (me). Hopefully it is a hardware issue. How long are you willing to wait for a software update though? (maybe it never comes) The thing is that the product is flawed, the way to get LG's attention in my opinion must be to return it.
