complete phone shutdown randomly - LG Optimus G (International)

I dont know how to explain it but im having this issue with my phone where randomly it will just completely shut off. i can leave the phone for hours in standby mode (where u lock the screen and it goes black) and not realise that sometime during not touching the phone its as if it has turned itself off completely, when trying to turn it on i get a weird boot sequence and it can require me to vol - and pwr to get it going again.
eg; i put phone down and it locks and goes black like it should. few hrs later i goto pick it up and realise its shut itself down totally and i need to turn it back on. the battery % is fine too. sometimes it has been as high as 90%. ive missed alarms and phone calls due to this but cant seem to find anything about it and no idea how to fix it
Currently running the e975 with savvy rom debloated, rooted with CWM recovery however it does it on multiple roms which makes me think it could be a factory defect?

go to service!
very less phones have this problems, noone can say, why!

Try stock rom,unrooted and unlocked,for a couple of days. You might've answered your question yourself :custom rom.although it's based on lg,it still can be faulty.

i thought the same thing too, so i did exactly that and i have the problem on stock rom also. I dont get the issue when running non stock based roms like CM10.1 but i do get a blue screen "external modem crash" when i run those roms which i can only assume is kernel related

What i am trying in an attempt to get around this is flashing the latest illusion 4.3 rom (custom roms give me a external modem crash blue screen) and then flashing the stock hong kong baseband (modem) with it. this way its a standard baseband on a custom rom. the blue screen could be due to a different baseband not agreeing with my phone.
I have just gone ahead and done this and i get network activity (signal/data) fine so i know it works now its just a waiting game to see if i get the bluescreen or a random shutdown
The problem is standard roms shut my phone down randomly with no error report on screen (basically like the phone turns itself off) and the custom roms ive tried ( a few diff ones) cause me to get a blue screen external modem crash.
Ill find out in the next week or so if i get any errors anymore. If not then i have found a way to fix it and ill post it in the QA section for others experiencing the same issues

If you get it on stock you have a defect product, KDZ it to totally fresh and send it in on repair. Even if it happens to "work", it can be still crash/break later and if you cant return then for some reason they might see you have played around with it and your warranty is void. Better to fix it so it works from the start in my opinion.

Phone continues to lock up

Alright so ive used the search and couldnt find anything. I have a rooted s2 running eagles blood v1.1 and last night i flashed over lite'ing theme and now my phone screen will shut off and wont allow me to turn it back on, i have to hold the power button and it restarts. Ive reflashed eagleblood even recovered back to stock with just root and it continues to do it.
Any help would be much appriciated :/

Probably best to post this in the rom developer's thread. Any number of things can cause this behavior.
I would but my post count is low and i am unable to post there, so for now i am seeking help here.
ive tried un-rooting the phone, flashing the stock rom and no root, but have the same issue.

i have tried this already, does not work :/
I'm having the same problem on rooted stock rom. It's getting more and more frequent. The phone just refuses to come back on after going to sleep. If I plug in the power/usb cable, it actually makes the connected noise as if it's actually awake but the screen stays off.
I've uninstalled all cpu and memory tweaking apps and am still experiencing the issue.

ive tried everything, flashed over and over, un rooted, different roms etc nothing has worked so i just used zedomax's stock rom to restore the phone ( problem still continues) called tmobile and will have my replacement within a day or so, nothing else i can do i suppose.
though my problem did seem to start right when i flashed lite'ing theme for eaglesblood (not saying that caused it )

im starting to think it is a phone issue myself, going to find out Tuesday when my new one arrives though i am hoping it was an error on my part because this phone has the chance to be fantastic.
I was having random shutdowns with my 1st phone, the thing is I never did have stock long enough (rooted after 45min of gettjng) to see if it was the phone or root/rom(s).
My second phone is working great without any random shutdowns, but I'm still stock(running on second day of testing).
Gonna root and flash tomorrow and hope everything remains the same if not back it goes before my remorse period ends.
I really think it's phone related rather then a rom because I've never had this problem with previous phones.
So I would suggest on exchanging it.

i do appreciate the feed back, and from everyone who did give it. after lots of research and back and fourth between stock and custom roms i definitely wanted it to be the rom so it was fixable but im about 96% sure its the actual phone its self.

Reboot Loop NEW FINDINGS

Hey guys, my gnex has just been stricken (for the second time) by the boot loop. Managed to fix it last time with a flash of the google image, but this time it isnt working.
Same as usual, mine features the greyed out wifi toggle as well, and reboots every time the screen goes off (which makes sense that I've been noticing it go off every 2 minutes).
I have found that the device will not reboot if it is plugged in and set in the dev options to "stay awake" while charging. This seems to keep it running, same if I set the time-out to longer. My theory has to do with the distribution of power...I think that something is telling the phone it doesn't have enough power to function.
Like everyone else I've done endless factory resets, flashed the goog image and such and such to no avail. Currently stock but I left my bootloader unlocked atm. I can still boot into recov and everything and even flash other roms.
Has anyone else noticed this, or could someone who is also having the problem confirm the screen thing?
I think last time I posted I was on winmo, missed this forum.
Bump? Anyone else having this issue?
Just send it in for warranty. I sent mine in and Samsung exchanged the phone
I havent been paying attention, are many people having this issue? It sounds scary. Were you on a custom rom when this started?
My Nexus has been stuck on "Turning WiFi on.." since I've had it. It would also constantly boot loop itself whenever the screen went off. I flashed the new AOKP build to avoid this issue, however, the WiFi still does not work If I'm ever on stock again, I'll give stay awake a shot.
I live in the U.S. with the GSM GNex, so warranty is out of the question unfortunately.
Fixed the loop by flashing aopk again with franco's kernel. Brilliant but my Wifi is still messed up. I flashed a new baseband XXKL1 and no improvements. I'm gonna just wait it out for a bit because I've seen some threads elsewhere where that has actually worked, but who knows. I'll probably cave and send it out soon.

Yes and no. It happened twice and the second time I fixed it by going FROM stock to AOPK with included kernel. Now it happened on THAT setup so I went back to stock and no dice. Its a very weird problem....
I got exactly the same problem. Wifi didn't work (grey toggle) so I tried to bring the warranty conditions back, but got an endless boot each time screen goes off.

Try booting into the bootloader and using the gnex toolkit to go back to stock and relock. Good luck. Logcat isnt even logging my wifi issues, its like my wifi adapter was removed entirely.

I have a Desire Z by my side, but of course I want my Gnex back as new. The only thing that scares me is the warranty. I'm not sure if it's still valid. I mean, apparently there's no sign of root/bootloaderunlocked, but how can I explain that suddenly my phone has started rebooting itself without any reasons?
Yeah, only option is to just try and see what happens.

Phone shuts down when taking pictures with flash

Hi everybody! I open this thread because I have a problem that I can't resolve: months ago I switched to CM 10.1 from stock ROM and I had that since 2 days ago (when arco68 told that soon he wouldn't develop this ROM for this phone anymore). So I had CM 10.1 alpha1 to alpha6, but my problem started from alpha3: in fact when I installed this release my camera starts shutting down the phone when taking pictures with flash (no matter at what resolution pictures where taken or if the flash was automatic or permanent), but only with battery under about 80% and it didn't appened when the phone it was in charge. So I read a lot of posts where people said it was a battery problem: since mine was one year old and it was rounded I replaced it with a new original one. Unfortunately the problem persisted, so I posted this problem in the thread relative to CM 10.1 ROM and I realized that other people had this problem, except that a lot of them resolve it buying a new battery (LIKE I DID!). So I waited for other releases with the hope it was a ROM problem...since Alpha6, when I realise that it wasn't resolved. So I decided to change ROM to see if it was a ROM problem and I installed a GB-based ROM: Mission ROM. But when I went to camera to take a picture with flash it appened again. So I wanted to know if it was a custom-ROM problem and I reinstalled STOCK ROM from the NANDROID BACKUP I made before installing CM 10.1. Unfortunately the problem continues to persist and it's strange, because It didn't happen before in my stock ROM. The only thing I think It could be it's that the flashlight installed on CM 10.1 broke the LED circuit because I try the full power option (or something like this, I can't remember) and there was a warning. But the strange thing is that I tried with all the 3 ROMs to keep LED on with a widget and the phone never shut down, no matter what was the battery percentage. So I wrote this post to ask someone if there is a reason for this strange behaviour and if it is a solution.
Thank you all
yesterday, i faced this problem, but my rom isnt cm10 by arco, my rom is simplified GB with s3 looks v2
at first i was shocked, and then i try to flash back into stock rom, and the LED works fine
my advice is you must flash your w into another cusrom or even stock rom and wait for the dev's solve this problem

Unfortunately I have already tried 2 custom ROM, and now I have recovered my stock ROM and the problem isn't gone...
me too sometime face same problem !! in more roms not one or too !
There are new develops! Today I noticed that the phone shuts down when taking pictures with flash only if the brightness of the display is over 50%: under this value taking pictures with flash don’t cause the phone to shut down. So my question is: how is it possible? It’s an hardware problem or maybe a firmware one?
Trying to answer this questions I have decided to make an hard reset of my phone, but I read that when the phone reboots after the hard reset it asks an unlock code. I have no idea of what code is this, so I want to know if this is true or not, and if it’s true how can I have this code before making an hard reset?

using CM 10.1 Alpha 6 , i found ur right about taking pictures with flash will turn shut the phone down if the brightness is high , u shall report that problem at the cm10.1 troubleshooting thread to get more testers for it
If you already changed the battery, maybe it's the jack that link battery to the phone...I think so cause you said that when under charge the problemdoesn't happen (because the phone take energy from the charge and not from the phone)...take a look over there...surely it's a mechanicalissue, not roms issue...

ok, but I don't know how to resolve this issue...I will try an hard reset...I think cyanogenmod wrote something in the firmware of the camera that is still present...with an hard reset maybe the firmware will be reset to stock...

Ok, I think I'll do an hard reset. Is there something to know before doing it (like codes to reactivate the phone, etc.)?
i think is battery....because when the phone is fully charged (or with anoter battery) when shutting photo with flash it stay on
why?
while taking the picture (camera+cpu+ flash (more power than torch) +screen ecc..) the battery voltage drops suddenly if it is damaged and this drop can swich off the phone

I had these screen issues too... But for me removing the battery and reflash the Rom did it...
Seems like your new phone has over heated and caused some serious damage to screen and maybe gpu\cpu.
Seen this happen recently with a ROM I installed also. But pulled battery out in time. And installed another.
I always watch out for over heating when installing a new ROM. Usually a sign somebody messing with CPU clocks.
For your sake though I hope you got it in time and can flash another ROM.

Hey I've seen this issue too, one of my friends has a GT I9192 and I updated his phone to the latest stock ROM first it worked very good, but one day he was recording something with his camera, and then played the recording after that the phone shut down, and didn't want to restart after taking the battery out and trying again and again, it reboots and after 3 or 4 min turns off again. I flashed some other stock roms but nothing, when I get in recovery mode, after some minutes the screen goes all blue.
And sometimes when restarting it shows colored lines in screen.
Went to Samsung Costumer Care (Saudi Arabia) they say that the phone has been rooted (which is not true) cause the KNOX Warranty bit shows 0x1
I don't know what to do.
The phone was bought in Saudi Arabia. And I live in Europe
Could I send it somewhere in Samsung CS in Europe cause i heard that here in Europe the KNOX warranty bit doesn't affect hardware damages (which I think that this issue is a hardware damage)

G4 Bootloop

Hi Guys,
i am really confused and a little bit angry. The Following happened to me today:
My Phone (Unrooted, Locked BL) was behaving weird this morning.
It just randomly crashed and wouldn't boot up.
Eventually i got it to boot once or twice, but still it crashed, shut down and Bootloop.
A Reqular Factory Reset did nothing. now i'm trying to install the Regular KDZ-File for the H815, but things are just not working as expected.
Has anyone else had this problem before?
Is it normal that the LG Flash Tool is on 1% for over 5 Minutes and nothing changes on the Phone screen?
I want to know what has broken my phone so bad, cause this time, I just used it the way it was supposed to be used, no hard drops, no rooting, no changing of software in any means.
First LG Phone and it broke with no warning and no explenation. I'm a little disappointed right now.

The same happened to mine. Are you able to get to download mode by powering off your phone and plugging it into your computer? Im able to flash stock ROMs but nothing helps. The phone reboots by itself at random times and makes it into the operating system a few times but is never usable.

Hey,
yes i can get into download mode.
I am able to flash files, but the phone wont boot up anymore.
I just want to save my data, but i guess i wont be able to do so.
So i have to get to the store and get a new g4
Luckily i made a backup of my two weeks ago, so not much will be lost.
I also send an email to the LG customer Service, will post their reply here too.
I am really disappointed by LG at this point, i usually had motorola phones and they didn't have random errors like this one.
I switched to LG, cause G4 sounded awesome, but this error is making me sad.
I am really thinking that i won't buy another LG Product, which is making me sad too, cause usually most things made by them are great.

//==============First Request by me:======================
Hello dear LG-Service Team,
i just bought the premium product LG-G4.
Since some days, the Phone is beginning to hang and reboot, resulting in a bootloop.
Sometimes the phone boots, than optimizing Android for about 30 minutes (100+ Apps installed). After this happened, i kann use it again, but not fully.
To shortcut eventual questions:
The Phone is in factory State, no Custom Rom installed. The bootloader is locked and the Phone has not been rooted.
The mistake seems to come from your firmware.
I am really disappointed, because i paid a lot of money and no have a product which is barely usable.
I switched to LG because of the G4 and i don't want to regret this decision.
Kind regards

Email and response, translated by me, so there might be some mistakes...
I don't like the response, it feels like not being taken seriously.
Well, nevertheless, i will go to the retailer and will see what happens.
I will keep you updated.
What do you think of this response?

That response is terrible lol. I called in and they said they do not support my phone because it is an international version. So there was nothing they could do for me.
I have a similiar issue, but mine was due to a OTA update, and I didn't know about the download mode until now.
Thanks.
Any tips when I can get into the download mode? I just wanna recover my personal data (images, and texts)? Flashing STOCK image would preserve the personal data right?
While your phone is off, plug it into your computer while holding volume up. If you are using LG flash tool to flash a .KDZ firmware file, you will come across an option that says Normal flash or CSE Flash. Normal flash will not wipe data, while CSE Flash will. I have flashed stock images and it didn't work. Hopefully it works for you though.

+1 I'm in same boat and exact same issue with my H815. I love the device but this is unacceptable.
I'm having the same problem, it just happened to me all of a sudden and now I can't even get to the boot animation. I've been able to get into recovery 2 or 3 times but usually it just restarts before it even gets there. I recently updated to the newest xposed framework (though I've restarted just fine a few times after I installed it), did anyone else here do the same?
When I get home from work I'm going to keep attempting to fix it, I've flashed my current TOT but it failed after rebooting. I don't know if I'm having the same problem as everyone else but I'll update if I can find a solution.
same issue here on the at&t 810. Starting about 3 days ago I started getting random reboots + bootloops. Sometimes it would boot to the LG logo and stick, sometimes to the AT&T logo and stick, sometimes to the OS and freeze after the lock screen appeared. I can get into the OS and use it for awhile, then it will restart and it all begins again. 2 factory resets so far and no dice. I am rooted on 10e but have a warranty device on the way which undoubtedly will be on a higher firmware and will likely miss out on the potential coming bootloader unlock. At this point I am probably going to sell on craigslist and get a 6p. The phone is great when it works and I love the size, the looks, and the screen, but the lag and these reboots are unacceptable.
Just a short update by me:
I gave it to the retailer, they said it would take about 10 Days.
I hope this stuff won't happen again or this was the last time i am buying a LG Product.
I think i would have been better off by sending it directly to LG but nevertheless, maybe giving it to the retailer will make my warranty stay longer
I will keep you updated, including firmware Version the phone has after sending it in and so on.
All of the sudden my phone today just froze leaving me with a black background and no animations, the phone is very hot if I try to use it on that moment. Even when I reboot the phone stays very very slow and says system it's no responding.
What can I do? Even when a Reboot it some times works normal then suddenly does it again.

Sounds like a heat problem in your case.
What happens if you pull out the battery, wait 10 minutes to let the phone get cold and than reboot?
Well, no luck on my end. I could only even get into recovery one out of every 50 times or so that I tried, and when I managed to I wasn't able to sideload any system software because it wouldn't initialize the driver (my computer recognized the phone just fine, except the ADB portion). Clearing the data did nothing either. Luckily I'm on Sprint and the phone's being recalled anyway, so I just walked in and they swapped it no questions asked. At least after flashing a TOT and clearing the data they shouldn't have an easy way to tell I was rooted or anything.

Thanks for replying, I completely restored phone today and was a success. No more black background.
same random rebooting issue here as well. and I just bought this phone brand new from a 3rd party :/
Update: I seem to have gotten past the problems after updating to 10n. Now running stock debloated 10n rom with no reboot issues (so far)
Update 2: Had 1 - 2 cycle bootloop on 10n

I don't see how you giving your phone to your retailer will extend your warranty. That makes absolutely no sense, since your warranty begins from your date of purchase.
My phone also ended up with the bootloop and having to exchange with a new unit. I'm on the TMO Variant H811.

Actually German Law is a little bit different.
Regular warranty is not what i meant in my post, i meant the "Gewährleistung" its an additional kind of warranty given out by the retailer.
There are some cases in which this "Gewährleistung", which usually lasts for about 2 Years is made longer. Mostly this happens when the retailer would have to send in a product for the third time, they basically give out a new one, which will be treated like a NEW device. So new Warranty, new "Gewährleistung".
I hope this somehow made sense
Today i got my phone back.
They repaired it.
Everything is like it was before, so i am pretty sure they didn't change it.
Firmware Version is 10d.
The Phone is working so far.
Will keep you updated if anything changes.
