Phone turned off and won't turn back on? - G4 Q&A, Help & Troubleshooting

I was listening to a podcast and out of nowhere my phone turned off. I tried to turn it back on, but it keeps getting stuck on the LG start up screen (almost like a bootloop). I manged to get it to turn on once and it turned itself off after a couple of minutes. I tried taking the battery out, but that didn't help. Any help would be greatly appreciated.

I looked into it more and found out it happens to a lot of people. Im going to try to get a replacement phone.
I have a question about the warranty though. Apparently they may not fix the phone if there is physical damage to it (because they cant tell if its your fault it broke). My screen has around 5 cracks on it. Has anyone tried to get lg to replace/fix your phone with physical damage to it? If so how did it go?

Just try it. Worst case is they send it back
If you are lucky the bootloop gets fixed and they ask your if you want to get the screen replaced for some $$. (Don't know the real numbers but frontscreen should be around 50$)
And don't listen to the service staff. The repair team from LG decides if your phone is getting repaired.
Most common mistake by too much people.

I had the same problem with my Lg G4. I took it to AT&T Service Center and they wanted to replace it. However, I have important stuff saved on the phone. Do you think they can download or recover the data? Is it possible to do? I would think they know how, but just wondering if anyone knows for sure.

If you saved it to the sd card then you are fine. If not you can ask them if they can. I'm not sure if they would be able to or not

Potential Brick, Unsure How To Proceed

Hello all.
I am an HTC guy through and through and have never owned a Samsung device. I'm familiar with HTC's S-OFF/HBOOT/bootloader stuff, but I'm not really all that clear on how it works for Samsung devices. I promise I've tried to do some reading before hand before coming to you, including looking at other threads, but they don't seem to be the issue I'm having.
I'm trying to help a friend out who has an AT&T GS3 that I unlocked for him and put an AOSP ROM on it a few months ago (don't worry, I made damn sure it was the AT&T version and no other carrier/international ROM).
He came to me today telling me that his phone suddenly turned off, and was not turning on again. I figure it's probably just a corrupted partition, something that I could fix with a reflash or something like that.
However, when I look at it, it seems to be something potentially worse. The phone did nothing with the battery in, so I took it out and put it back in. The phone very briefly vibrates, the Samsung logo shows for about 1.5 - 2 seconds at most, and then the screen goes dark.
When I try to enter Download Mode, I'm able to get to the custom software "warning" page, where I press Volume Up, and it shows me Download Mode and "Waiting" (as I expect it to) but then the screen just goes black again after about a second or two.
It's roughly the same with Recovery Mode, I can catch a glimpse of what looks like CWM (but I'm not entirely sure) and then the screen goes black.
If I choose to forgo the battery altogether, and I plug it in straight to the wall, the red LED on the top right lights up for again maybe 3 - 4 seconds at most, the light goes away, and the phone briefly vibrates, shows me the Samsung logo, and then goes dark.
I'm confused. I don't know if it's a brick, but then again, to me as an HTC user, "brick" means Qualcomm USB Download mode. I've also read about this infamous Samsung Sudden Death Syndrome that struck some of the 16 GB models that Samsung sold (and yes, you guessed it, this is the white 16GB model).
I don't really know what other troubleshooting options there are (but as I said before, I'm an HTC guy). If any of you have any sort of advice I would love to hear it.
Thank you for your time.
I've seen several users on here in the last few months with this issue. I worked with one of them for awhile trying to get it straightened out but couldn't resolve the problem. Some of that was due to the nature of the problem and some was probably due to the fact I didn't have the phone in my hands to help the new user better. I believe the user was able to get an exchange at an at&t service center. Sorry I can't offer more assistance. Keep us posted if you get a fix.

I appreciate you trying. I know it's such an odd issue that it's really hard to diagnose. I thought perhaps it might have to do with the battery somehow being "bad", but then the problem would be gone when I go AC only.
He's not against the idea of going to AT&T, but I feel bad; I convinced him to unlock and let me flash a new ROM so I feel that I should at least put in a good effort to make sure there's nothing more I can do.
Yeah, the biggest problem is that once you get into recovery or download mode, the device reboots/loops. This eliminates the possibility of any kind of flashing or wiping.
You might have a bad motherboard. If I was you I'd take it to att for a replacement. BTW if he doesn't have insurance for the phone they do have open enrollment , I'd wait a day or two after enrolling to submit a claim.
Wish you the best.

It's a realllly long shot but he could contact mobile tech videos and tell them his issue and see if a jtag repair would help. If it's hardware of course he is out of luck but it's worth a shot and a lot cheaper.

[Q] Hard bricked, but...

Hi there, I hard bricked my Tab S 8.4. No reaction to anything I did (key combinations, let it charge for hours, stuff like that). Don't know how it happened but it just crashed to death shortly after installing an inofficial Lolloipop build from here. I don't think a ROM can make a device not turn on at all. My money is on hardware failure.
Anyway, brought it in for repairs (willing to pay since I knowingly voided the warranty). Got the call yesterday. They said the software had been tampered with and they can't repair it. I objected that the software won't break the hardware but no dice. They won't even do it for cold hard cash.
BUT: To see the 'illegal' software they HAD to get the thing to turn on . And if they got it to turn on somehow, so can I. Or... am I completely wrong there and they have some magic fairy dust?
Any ideas on how I could accomplish what the repair guys could obviously do? There is no important data or anything on it so I'd be happy with Odin mode, CWM or whatever.

I kindof had the same problem, but got mine repaired.
May I ask where you send it to for repairs? Was it Samsung or a local repair shop that told you they could not fix it?
And did they send it back to you? Kindof weird they won't fix your device after you say you are willing to pay for it.
Depending on where you live, Samsung covers a lot of 'problems' in the first year of the standaard warranty.
As for turning on the device..
What options have you tried yet?
If you connect the tablet with usb to your pc and turn it on, does it get recognized?
And if so, as what?
But if your screen doesn't turn on, you're probably going to need repairs anyway.

Over here you bring it back to the shop where you bought it. They will try the simplest solutions in house but usually send it back to the manufacturer. I think the information came from Samsung directly. Another theory I have is a simple lie. They tried it in house, nothing came up, some clever guy screamed 'CYANOGEN!' and they all high fived (I have a vivid imagination )
As for turning it on: tried everything. It's not only the screen, it did nothing at all. No signs of life whatsoever. Of course the PC wouldn't recognize it since it was turned off.
I'll pick it up tonight. Maybe whatever they did to see the software tampering stuck and it will at least go into Odin mode. I can work from there.

But it you think it came from Samsung directly, then I would advise you to contact Samsung.
Here is a link from an article where it states that Samsung covers bricked devices, but only the first time. (Dutch article, GTranslated english)
I have no idea if this also counts for where you live though.

Magic dust it was. Got it back, dead. Came home a minute ago, put it on the charger. Lo and behold, the battery appears. Device turns on too, boots Lollipop goodness. 0 per cent battery but hey. Whatever they did, they obviously did NOT realize they solved the whole problem with just their diagnostic :laugh:
Thread can be locked if the PTB deem it necessary.

It simply reset itself after the battery completely died. Black screen and no response doesn't mean the device is off.
As soon as they switched it on they would have seen knox had been tripped.
Sort of did you a favour by telling you it wasn't bricked.
I had the same sort of problem i connected my tab to my laptop and used the recovery mode key combination then my tab came back to life

Sorry download mode not recovery mode
Comforts me while ROM developing that the only reported case of a hardbrick was here - and the battery just died.

[Q] Phone wont start past LG opening screen

Hi, hoping for some input. I am not super technical.
We have a newish LG G3 phone. TBH, it is reconditioned by the authorised service centre as it apparently came out with flaws. It came with full LG warranty. We bought in January 2015. This week, it suddenly would not turn on past the LG screen. We tried changing batteries, leaving the battery out, nothing. We took it to the same authorised repair centre. They turned it on and said that we had rooted the phone and had voided the warranty. Now, I would not mind paying, if we had infact rooted the phone, but we had not. Further, they did not look into the electronics of the phone at all. They are asking $225 which is HUGE for us, I am wondering please, is this a known problem? We had not clicked any download links, in fact, not even downloaded any apps in the days preceding. I am so angry that they wont even look into the phone, the onus should be on them to prove to me that I rooted it, not to assume that I did when I didn't lol. Your help is so gratefully appreciated.

Did you buy from a carrier or a physical store?if you did it would be best to directly take it back to the place where you bought it and get them to sort it out?
If the person says that then the person isnt doing their job properly. A variety of issues not caused by you could have happened that result in this sort of problem. This isnt a known problem.
Does it boot into download mode?

We bought it from the place that is the authorised LG repairer in Sydney. I was getting my screen replaced, and noticed they had a sign up saying they had these reconditioned phones with full LG warranty. It was explained to me that these were the newly released phones that came out with glitches, they were repaired fully. So we did take it back to the same place, and I agree they are not doing their job properly, they have us by the short and curlies . I have mediated with Fair Trading, who have come back to say that the device is rooted, warranty voided lol. They still have NOT opened the phone!!! So frustrating.
Please ask them to explain how the device was rooted, they at least owe you that much?
When you got it did you or them turn it on and verify in the store that it was working at the store before you took it? Did you perhaps download the Lollipop OTA and then something happened to it
Does it still boot into download mode? Im pretty sure in your case you can still fix it if you can get it to boot into download mode. Pull out the battery and put it back in, hold volume up and plug it into the computer. Let me know what happens

LG G4 Boot Loop - How to recover your internal data

My initial issue with the LG G4 Boot Loop problem is I got data in my phone I need and don't want it erase/reset. So in reading other forums, I read that some people have been able to get the phone to turn on for as long as 10 minutes if they put the phone in the freezer for 20 minutes. Has anyone tried this?
LG states that this is a hardware issue. Something to do with a loose connector. Does anyone know exactly where in the motherboard this connector is located? I have a friend who has worked on cell phone motherboards and would like to be able to tell him where this may be. I am not worried if it invalidates the warranty anymore. The data is too important to lose. Does anyone know where this connector problem is?
Thank you from Texas!

Remove Lock Screen k430dsf Dead family member.

Hi. Probably an unusual request. The sister of my wife has died. She had cancer, was 34, and let an 1 year old daughter.
Wife and her sister were really close and my wife forgot the pattern lockscreen.
She wants the recover the photos of my nephew . =/
Is there a way?
I have found DR.FONE but that model isnt supported.
I have experience with samsung phones. Never done anything on a LG.
I can provide some sort of prove that she passed away if required.
Thanks a lot.
I doubt you can do that, but in light of situation you can contact LG support to see if they are willing to help.
I don't think you could do something via adb or fastboot.
I guess only way you have to do is disassembling emmc and mounting it to a pc through some stuff. Then all you need to do is finding photos and copying them.
I think you need something like this:
I'd like to help you if I have knowledge about what issue(s) you have.
Thanks for the reply.
I really dont know if its going to be possible to recover even if LG stepped because privacy issues.
Legally the phone is hers. Its just sad to lose all those photos.
To help, i dont know why her SD card was corrupted. Locks both PCs i tried on and when it opened, was all messed up.

Well I told you, if you can contact LG support also if you can go to LG service if there is one near you. And most importantly you should mention that you can prove she's dead and it'll be good that if you can prove that phone belong to her (some kind of bill or anything else releated to her and phone)
The method mentioned above can or can't be successful so if you don't know how to do it better don't try it.
About SD card it was probably adopted so it can't be recognised by any other device than that phone, orbit was simply encrypted.
