Galaxy S3 bricked... sometimes??

So, lately my phone has been acting kinda weird.. Basically, it'll shut off on it's own, no matter what my battery level or if I'm on the charger, its pretty random. When I go to turn it on, it shows me the samsung logo and shuts off after about 3 seconds of the galaxy s3 logo. It does the same in download mode and recovery. The phone will stay off and do that for an hour or more, and then itll turn on and be all dandy again for hours or at least another day. I'm going to take off all my pictures on the sdcard and odin back to stock as soon as possible for warranty, but does this sound like a hardware failure or software? I read about the s3 sudden death syndrome, but this one isnt permanent. Any ideas?

I agree with your assessments.

I'd wonder about overheating or a bad battery.

what's your setup as of right now?

Beware if it shuts down when your flashing back to stock in the middle of the process it may never turn back on.

It might be the kernel that came with the ROM you installed. I used to have problem with ktoon kernel.

I'm running Darthstalker XI, the problem happened with both the stock kernel and the faux samsung kernel. The battery is fine, its completely flat with no bumps or humps. I managed to turn it on once yesterday but as I was getting ready to transfer over the files the phone shut off and didn't start again. I'll try to get it running tomorrow.
EDIT: Now that I think about it, the problem happened when I dirty flashed XI over X. Afterwards I did a wipe and clean install of X1 and the problem persisted. Has anyone else on Darthstalker/UDVLJA based roms had this?
EDIT2: Well after being on the charger all day, I noticed that the green samsung battery icon was on the screen, something it only does when it's about to turn on properly. I instantly pulled out the sdcard and put the latest cm10 nightly and gapps on there and I booted to recovery, wiped, and flashed them right up, no issues. I booted just fine, I signed up and I was downloading youtube, latest now updates etc (bare essentials).... and it shut off again. I'm positive now that it's a hardware failure

If you have an app that controls kernel voltage that is still set up for set on boot and the voltage is too low when it boots or is granted root it'll kill it in this manner. Otherwise your phone is [email protected]#

I'd wager that if any overclocking/undervolting was done, it was disabled at the onset of problems. OP seems smarter than orangutan.

I used the phone for work, not play, no overclocking was done neither was any undervolting. I ran stock kernel settings.

I remember a time when XDA had helpful answers and users weren't reduced to insults. I've been around a couple years, hacked more phones than I can count and flashed hundreds of roms in my days, back when everything was still done in adb and terminal emulator. It's no wonder a lot of decent user has started moving over to rootzwiki

[Q] Phone with CM restarts in airplane mode

Hey guys,
since ~a week I got a heavy-ass problem with my Samsung Galaxy Nexus (GSM). I am using the Cyanogenmod Nightly Version cm-11-20150412-NIGHTLY-maguro.zip (bootloader version primemd04; cwm version 6.0.5.1). I know that nightly versions are not really stable and still have a lot of problems, but so far everything didn't went that badly. At least I was able to use the phone...
So last week I put my phone in airplane mode. That was when the disaster started.
Now what happens when I start my phone is, that it starts in airplane mode with wi-fi on and no matter what I do, restarts after ~1min. Sometimes it even shuts down, when starting it in recovery mode.
What I tried so far is:
factory reset ---> most of the time it shuts down halfway done and restarts as if nothing happened.
updating CM ---> restarts as if nothing happened.
I'm really lost right now, but still don't want to give up all hope.
Thanks for every kind of help!!
Cheers,
Lovis

Try to get a legit application that tells you the real CPU temperature like FKUpdater, in case you have franco.Kernel. Then just run heavy tasks on in. If it just ****s doen,might be a problem with the battery. Mine just shutdown on itself just by doing common tasks like calling. Replacing the battery fixed it. Another thing O realized was that if you plug it in the charger and use it was helping it not restart. Try this method. If it restarts then its pretty much a ROM or hardware related problem, if not then a battery problem for sure.

It has to be some kind of ROM problem. Before I got in airplane mode the phone worked almost perfectly.

LG G3 freezing and restarting, staying in boot loop sometimes

Hello,
Since 2 weeks ago my phone has been started acting all weird. It started with my Phone freezing and restarting itself one morning. It showed the LG logo for a few seconds, then went black and the same thing repeated. LED did not start blinking at first but after a few loops the LED came on, the animation played and phone turned on nicely. No more such problems during the rest of the day.
Fast forward 2 days. It got worse. The freezing and restarting happened more often and at one point it was in the LG logo -> black screen -> LG logo loop for a good 10 minutes before it booted. It also drains my battery about 10% every single time.
So I decided to do a Hard Reset when I managed to keep the phone running long enough. The hard reset process itself worked flawlessly, no issues during the reset what so ever. I though the problem was over until a few minutes after the hard reset when I was reinstalling my apps, it froze and restarted again.
I started googling about the issue and found a few matches. Some people suggested replacing the battery and some suggested putting a piece of paper between the battery and the SIM card slot from which I did the latter. That actually worked for a few days until the reboots came back and it got worse by the day when it finally was completely unusable since it kept restarting after booting up (usually it didn't even get to that point). Then I decided to try a new battery because it was the cheapest option available at that moment.
At first all looked good on a new battery but still, just a few minutes after rebooting the phone from a new battery it froze yet again and restarted itself. So 25€ wasted on nothing.
At this point I'm starting to run out of options and really would not like to buy a new phone since my G3 is only two years old (warranty just ended in October 2016).
Any suggestions are more than welcome at this point.
Best regards,
Taavi

Yesterday I tried flashing the stock V30B marshmallow ROM onto the phone using LG flash tool 2014. It lasted without restarts for about an hour and then it all started again.
So in conclusion:
A) It's not the battery.
B) It's not the software.
C) Thus it must be the hardware.
Since my warranty is void already, the repair costs would probably be quite large.
I think the only chance left for me is to suck it up and buy a new phone.
It was fun while it lasted though. RIP.

Funny thing is that after I removed my SIM card, the issues have stopped for ~24 hours. Yesterday I was able to browse reddit and watch videos for almost 2 hours straight with no issue when I had no SIM card in the phone. I will try inserting the SIM card again after I have fully recharged it to see if maybe it has something to do with the SIM card connection.

Put in the SIM card and it didn't even last 24 hours before restarting. Took it out again. Unfortunately it now restarted even without the SIM card so it still must be some hardware failure.

Same issue here. Changed battery, factory reset, rooted and TWRP+CyanogenMod 14.1 flashed and SU granted.
Constant reboots. Sometimes bootlooped until I remove battery

Having the same problem. Tried new battery but it turned out to be a cheap clone that was worse than old battery. Got another from mbuynow which last longer but still restarts but not that often. Tried the paper trick to to avail. Also tried the LG suite to see if it helped but no luck. Running marshmallow 6.0 and have done a full reinstall. Is this likely to be hardware problem?

Cannot tell for sure but seems it is a hardware problem which is really sad since besides the restarts the phone is still in very good shape. I would take it to repairs but as my warranty is already void it would make sense to simply buy a new phone and sell the current one to parts.

I have the same problem... I flashed CRDroid or something with Android 7.0, it booted normally, but then, restart after few minutes... It can boot normally with the usb to computer, but not with charger. It can also boot to twrp, wipe, install and fix the system works, installing other roms works too, and they can boot normally, but it shut down, as soon I remove the cable... I thought it was nougat rom, it change some in system files or drivers like battery options... I'm out of options...

Seems like a battery issue I think you need a new battery if it's working without the wire plugged in

I have 2 phones. This thing seems to puff exactly after 2 years coz they were bought in difrent times and both of them emerge this issue after 2 years for each. boootlops were after few minutes from start. In case of first one new battery was a bingo but i did not investigate second - im going maybe for new phone. Funny thing. Maybe product life time was to planned to good(for producer)?

I was a great phone, longest I have and most customised... Very agile, never had bricked, bootlooped or failed to flash... Thank you for your great support, LG G3.... Rest in Peace... If someone can bring it back to life, I'll be back to that.

I'm counting on someone stumbling on a fix as well. It's still an awesome phone expect for this stupid thing.

I had similar issues but I realized that different SIMs seemed to work with the phone. Went to my carrier and requested a new one. Since then, no issues. Maybe something with the sim card slot?

It happens even when my SIM card is not in the phone. It could easily be the SIM card tray but cannot confirm without taking it to repairs.

Did you try disabling Location?
(I had random reboots when the battery went to 25% and when i disabled Location services,it got fixed)

One of the hard resets I did was from full charge and I didn't enable anything, including location. It still went into the reboot loop.

It might be a hardware problem in some LG G3 phones.
It began rebooting and bootlooping after 2 days,that i had disabled the location services.
Now i'm thinking of getting a new battery but i don't really think it will do any effect..
So i might buy a new phone..

I had the same problem as you,i bought a new battery and everything got fixed.(you need exact the same Model of battery so when you go to a store note the model of the battery)

Temporary Fix
1- Remove the SIM, turn on the phone, put it in Airplane Mode.
2-Insert the SIM turn on the phone.(Don't change Air mode).
3- Turn off auto backup/restore in settings.
4-Go to network setting>Preferred network Type.
5-Turn Off the Airplane Mode and immediately SELECT THE 3G only(Before it catches the signals), in some phones WCDMA only.(Do not Select 4G/LTE/2G).
6-Done
7-Restart the phone.(Now it will not reboot)
Drawbacks:
In 2G signal zone, There will be no signals.
Its a hardware problem,But its a way to trick it.

Note 2 keeps restarting everytime!

Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Everything stock..like I said! Before flashing to the newest rom too, everything was stock.

Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?

Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.

I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.
Click to expand...
Click to collapse
As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.

Obviously you move all of your stuff to a computer or usb SSD or HDD and factory reset or flash stock firmware with XiaoMiFlash tool.

Yesterday my phone kept restarting, and my Sim card wasn't functioning when it did turn on. It wouldn't even power on after a while, had to wait for about 20 minutes and try again. One weird thing I noticed is I couldnt search settings (setting suggestions wouldn't work) I used an air compressor on the Sim card slot with the cover removed and it seemed to help. But I also did some software changes to see if it would help. like turned off memory extension and cleared dalvik cache and cache with recovery. I'm not sure what exactly made my phone function like normal again.
So after about a day the issue starts again, first my Sim card shows up beside my clock with an X through it,the data icon gets grayed out, I will not be able to access the mobile networks option In settings without my phone freezing and a process has stopped responding message ,and my settings suggestions stop working too. I'm just really confused lol, because it seems like software, but the only thing that actually made my phone work like normal again, was removing the Sim card slot and blowing Compressed air into the phone. Simply removing and reinserting the sim card did nothing, but the air helped.
I can't tell if I'm having a software issue, or hardware issue, or I suppose it could also be the sim card itself maybe, but yeah if anyone can shed any light it would be amazing.

I think something is overheating in the phone. I haven't had any issues since it's been a little cooler weather wise, where I live.
Second guess is the phones been "sweating" moving it from hot outside to cool inside ac, maybe created internal moisture condisation. I'm leaning towards mosture because taking Compressed air to the open sim card slot, seemed to be the only thing that worked.
I am wondering if this is something that can be easily repaired (opening phone and resoldering maybe) or at least that's my hope, I really don't have another phone to use if I send this one away to be fixed.
Edit: So it's been a few weeks now and I haven't had any issues.
I downgraded my kernel to previous version (BaalamKernel-2.1.1_alioth vs newest)
And I've been using my phone without its case in hopes it can breathe better or dry out any moisture that built up over time.
Still not sure if it's hardware or software but knock on wood, no issues so far.
