[Q] Major problem with my stock ATT E980

Okay, I originally got this phone as an upgrade over my HTC Inspire in July. It worked great, minus a few random reboots every once in a while (if I left it in my pocket for a long time or if it was really hot in my car it would do this, but that was it). Then, about a month or two ago, I rooted it and installed a custom ROM. I noticed that a bunch of my files were missing from my internal SD card, but I wasn't too worried about it. Then my phone started acting really weird and got stuck in a bootloop. I was able to boot into recovery, but I ended up using the LG Flash Tool and went back to bone stock. Still had the issue, except I noticed that my signal would drop, and then it'd get stuck in the bootloop. So, I contacted AT&T warranty and they sent me a replacement. Now the same thing is happening to this one. It gets warm, loses cell signal, then reboots, sometimes a bootloop. This phone hasn't been rooted at all, it's been left stock. So I contacted AT&T and the guy in warranty said he thinks it's the battery, but he didn't have any in stock so he couldn't send a replacement. So I was thinking it was the battery and called LG after it seemed to get worse. They told me that they could replace the battery free of charge if I send in the one I'm using first. Since this is my only way of communication, I contacted AT&T again, and they're sending me another replacement. (Said if this one screw up too, they'll give me a different phone all together). The guy had me download some AT&T remote support app and he looked at the battery health and said it's reading fine, and that because it's reading fine, he didn't think it was the battery. :|
Here's the weird thing, about two weeks ago, it went into a bootloop. I took out the battery for a minute an tried to put it back in. Nothing. I plugged the charger into it and it basically told me that it didn't have enough juice to power on. (battery was at ~40%). So I took the battery back out and tried again. This time it came on.
Then last friday, I was jammin out to music while I was working, it would reboot when I unlocked the phone. (battery was in upper 90%'s). I plugged the charger in while it did this and everything came up as it should. But after taking it off the charger and trying to do more work, it happened again and again.
Like I said, this phone is straight from AT&T and has not had anything flashed onto it by me, hell I never even disabled all the AT&T bloat this time. I've tried a hard reset, and it didn't help. Does anybody know what would be the cause of my problems? I really like this phone and really hope I can get this figured out.
EDIT: Forgot to mention, the phone still has its IMEI number and it has the value pack update.

Got the second replacement in the mail today. It hasn't screwed up yet, but only time will tell.

Wow hope this works for you. I just got 3 Optimus G Pro's on 12/30/13 and all 3 of them to date have not had any issues. 2 black and 1 white. 2 which are running stock. 1 stock which has had a bunch of the bloatware yanked (that we could get off of it). 1 stock which has had nothing pulled, everything left the way it is. And the 3rd one (which is the one I use) which I rooted to CyanFox 4.4.2 and later to CM11 4.4.2 Nightly and haven't had any issues like the ones you've explained.
Good luck though hopefully your issue is gone. Seems like a nice reliable phone (minus LG not wanting to support it furthermore ).

I really hope my issues with this phone are done too, I really love this phone. If I don't have any issues, it's going to get rooted and updated to KitKat. Otherwise, I'll try to get AT&T to give me a MotoX or a HTC One.

Yeah I like this phone with KitKat. Looks like a larger Nexus 5
Only problems i'm having with CM11:
1. ATT Visual Voicemail will install but upon playing voicemails program will freeze and crash
2. Tried Google Voice however you can only hear the voicemails through speakerphone, headsets, or bluetooth. Voicemails will no play through earpiece.
3. CM11 doesn't have Screen Recorder yet (Which CyanFox did although CM11 is still fairly fresh).
4. I would like to have the LG Camera app back! Dual video recording and some of those other features are gone with the android stock Camera app. Need to look into porting that back over to KitKat (if I can).
That's bout it though...

Haha yeah, this phone is beautiful with stock Android, I just end up missing certain touches that LG puts in their overlay.
BTW, this phone is doing the same thing as before. I strongly believe it's the battery b/c when it went into a bootloop, I took out the battery it was warm, so I put it in front of the AC for a minute to cool it down and it's been working fine since. So, I'm going to call AT&T and see if they will send me a battery, and if they can't, I'm going to have to send this one in to LG and be without a phone for a week...:'(
UPDATE: AT&T told me "since we have tried everything else-hard resets, replacement phones- and nothing worked, we will send you a battery since it's the only thing that has stayed persistent through this ordeal. We just got some in stock and are sending one your way. If the problem continues to persist, we will replace the phone again." IT'S ABOUT TIME!!!

Just curious, but what if I continue having this issue after I get my new battery? Should I try a similar mah zero lemon battery or just have att give me a different phone altogether?

i think there is an issue with the battery and whatever cable you use to charge the phone.I had to Lge980 when I used a thin cable I have in my room sometimes it did not charged at all and or shut down itself even when the battery had half charge ,sometimes it showed full charged but if I plugged the phone to a thicker cable connected using the oem charger or a usb 3.0 port at my laptop it showed the real charge level at 1/4 charge.I myself could't do anything since I got the phone second hand but as long as I used thick cable connected to a oem charger usb 3.0 or eben 2.0 I had no had any issues.

how'd it go?

I've had the exact same problem with my E980 and the refurb they sent me. Contemplating a battery replacement now. Did a new battery fix your boot loops?

If you want to stay on stock i recommend going to jellybean TOT 10k and rooting and installing a custom recovery back up the rom, and flash hkfriends kernel, and see what happens if you raise or lower your phones voltage, that might be the problem with it rebooting.

THE NEW BATTERY SOLVED THE ISSUE, BUT ONLY FOR A SHORT TIME. I upgraded to an HTC One M8 since, and haven't had hardly any problems with it, aside from the death star's BS

Thanks for the response. I talked to the techs at an AT&T direct service center and they told me it's a common problem with the Optimus Pro. I'm on my third one in 8 months now and this one started randomly powering off within 15 minutes of when I took it out of the box three days ago.

Yeah. My issue was the battery for sure. Make them replace the battery and it should temp solve the issue

From what I read on the first e980 i had these phone tend to have a hardware problem where the power button is creating the same issues as OP. Some refurbished e980s have the hardware problem solved.

[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

Help with Tab Pro 8.4

Lately my tablet has been turning off and then going into a loop when it restarts. The only thing that seems to get it out of the loop is when I plug in a charger. I am stock all the way. Any help will be approciated.

You could try wiping cache while in Stock recovery, or doing a factory reset and see if that helps, otherwise you might have to trace down to see if a specific app causes this problem

Well factory reset did not help ....

Neither did wiping the cache ....

@uhmump95. I was having similar problems about 6 months ago. I was only able to solve the problem by re-flashing the latest OS. If you are not familiar with this process go here for a good tutorial on how to do it. You can also go here to get the latest stock OS for our 8.4 tablets.
I have since moved on to custom ROMS but the above got me out of the same issue you are experiencing. Good luck with getting it fixed quickly.

I have found a cause.
Mine started getting random reboots the same a few months ago, perhaps one month before the warranty ran out. It stopped after a full reset and I assumed it had been a software issue and I let the warranty period expire :silly:
It has happened again a few times, but I have found why: It only happens when the battery is very low. Somehow the battery sensor is not well calibrated, so it never charges over 90% and instead of shutting down when it gets low it keeps working till it malfunctions.
I don't know how to repair it, though. I haven't rooted it yet and I'd rather not remove the screen to get to the battery for now. Should the problem start being too cumbersome I'll try any of both solutions.
Does anyone know of a less drastic procedure? Thanks.

Note 4 rebooting randomly then not booting fully.

This is a serious problem. In the past couple of days, I have been using my note 4 and it reboots out of nowhere and will not boot again. I tried wiping cache, no dice. Tried factory resetting it, no dice. Used the Verizon official software repair tool, no dice. I even flashed it manually with ODIN and used a PIT file to re-partition it and that fixes it for a couple of days, but then it does it again.
Nothing will get the device to boot again, and it will not boot into safe mode either.
Does anyone have any idea as to what on earth is going on? I've had to put my SIM card in another phone that works.

Hello Macmaster2000, tried using another battery?
My current note 4 situation, though some battery/charging apps say the battery is "healthy".... when its not plugged in it will go into a boot-loop after about 1-2 hours of usage on battery even if it had 80-90% of battery life and it would still boot-loop.. but when it is connected to the charger it wont boot-loop..
Sadly, I don't have a replacement battery to tell you if that's the problem to my bootloops or other :\ worth a shot thou!

Well I just tried to plug it in and it works! Thanks man!
Also I talked to a friend and he said the exact same thing, so it looks like I'll be getting a new battery soon!

:highfive: No problem glad to be of help! :highfive:, my batteries came in(I've ordered 2 off amazon due to a bad past experience with my old nexus 4 when i ordered one. was a month without a phone . one from BinTek and the other sais its OEM but i say "yea right" as long as it works ) and as well it solved my problems! I just wish I Didn't factory reset my phone :crying: back to square one again ah well live and learn.
another thing to take a "note" of ; =D when i've reinstalled 5.0.1 i had a crash message along the side of "NFC crashed failed to respond" maybe our batteries aren't actually "dead" maybe faulty NFC chipet or whatever on the battery preventing it from staying alive (i truely dont know but this sounds suspicious..... it could be that our batteries were bottomshelf.... or.... *looks at samsung* )

I think the best batteries are from Anker, best sellers on amazon and I've never had a problem!
Also, not sure on the NFC crashing, I use it daily and haven't had an issue.

Lg G3 constant shutdown

Hey there im turning to the community for a bit of help...
First of all here is my phone info... Bone stock non-rooted
Lg G3 D-852 canadian version with Bell
Running android 6.0 kernel 3.4.0
Build number mra58k soft version d85230h
here is my issue, lately when i do random things on the phone it shuts itself down and goes into a bootloop.
in order to get the phone back on i actually have to plug it in and for some reason seems to short it back out of loop and into boot.
At first when it started it was booting up completely then shutting down 4 times. after that 4th time everything was good.
now it just stays stuck in a look until i shove a wire up its hole.
ive come to notice that most times whe it shuts down it seems to be when i try to do many things at once or load up a video...
sometimes even opening a picture will shut it down... it almost feels like when an overclocked system just ticks off.
im not quite sure where to go from here, phone is 2 years old but id love to figure this problem out
edit: yes i already tried a factory reset
edit 2: i just tried another factory reset.... now it wont even load up. itll boot all the way to the os (if plugged in) then shuts down and just says its charging... completely out of a phone now ffs

Its battery related problem.

Yes, try it and let us know later

Try an Anker battery, worked perfect on 2 G3's I had, while both the stock batteries bootlooped.

sorry for your battery as well but heck ill give it all a try

well sunofagun.... i poped the new battery in and she booted right away like nothing ever happenned.....
have i ever told anyone i love the community thank you so much everyone

Very common. Batteries usually last a little less than 2 years for these then you need to get a new one. Thank God these have removable batteries.

i remember i had once gotten a new battery for my sgs2 but it was crap lol

I'm having problems with my screen, it gets dark and I do not know why, it can be without disturbing half an hour or maybe an hour, please someone who tells me why this may be this fault, I'm in MarshMallow
