Why? Nobody knows what serials are affected or the extent of the problem. Keep daily backups (as you should be doing anyway) and worry about it if it bootloops. Here's a hint - it probably wont.

I don't believe this at all. 602 was basically the newest revision anyone could quote at the time that LG "Acknowledged" there was a fault.
There have been reports of 603 units with the problem somewhere. (On either Reddit or this forum, can't remember where)
Given the way that LG are handling warranty claims and not honouring repairs for boot looped devices which are rooted or bootloader unlocked.
I think its way more likely that LG have just realised that most devices seem to take around 6 to 9 months before they fail, its easy to cost manage the issue by swapping them all around with minimal repairs until all warranties have expired.
I doubt they are making any new G4's now that the G5 is out. They will be hoping everyone who has a failed device with no repair options will just upgrade to the G5.
Those of which move to other suppliers would be considered acceptable losses.

LG has never acknowledged anything.
No need when they already replace any faulty device under warranty. Can't get a warranty then look for another device that comes with one.

If its bootlooping how can they even tell whehter its rooted or bootlooped. I've read accounts where they've replaced motherboards and returned the device.

I've got one, no problems.
Its dual sim and the number of people with dual sim i find complaining about boot loops is minuscule. Mostly the single sim lot. I'll take my chances.
Guess what, if mine goes south, i use warranty. If no warranty left, i'll buy another G4 with warranty at half the price i paid when it launched.
What am i going to do with those leather backs and cases otherwise

The never officially acknowledged anything hence the quotes.
They unofficially confirmed to android authority that there was a problem here:
http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
Unlocking the device requires submitting the IMEI/DeviceID to LG which they can use as a warranty blacklist.
AFAIK an unlocked device advertises its unlocked status on the bootloader which is visible before the boot-loop occurs.
LG have a root checking service called RCT which logs the date and time of any root related files/binaries to the /persist partition and I believe it also sets a flag in an RCT partition.
It builds a log file of which exact root elements it has seen eg su binaries/ busybox binaries forbidden file extensions and the date/time it detected the latest one of these elements.
Simply enter the hidden menu and find the RCT option to see your devices status.
LG can simply disable the faulty cores on a boot-looping device and check any/all of these.
The best way to hide root that I have read on here is to fry the motherboard by applying 24v to the battery contacts. If LG did refuse to warranty though you have absolutely no chance of recovering from that.

Is there no way for them to detect this ?

Nothing is undetectable.... The post I read this idea from suggested that this forced the device into the Qualcomm recovery mode (most likely the flash chip can not handle the 24v but the lower level hardware can).
Given that the source of the problem is a faulty solder connection to the flash chip. this advances the problem past the faulty connection stage to the completely disconnected/shorted flash memory stage.
If they cannot boot/read the flash memory chip at all they have no way to prove you rooted. providing you didn't unlock your bootloader.
Obviously if you push it too much, physical damage like burn marks would be a giveaway of foul play.
I read one user had been denied warranty due to oxidation on the mainboard... given the faulty soldering and thermal issues this could cause oxidation/residue on the mainboard.
Another user was refused warranty because a warranty sticker was not present on one of the screws of his device. (This concerns me because my device has no such visible stickers)
I personally have a 506 device tied to a 24month upgrade contract that I started in Feb, I usually bootloader unlock and root within hours of unboxing but read about this issue first and have kept my device stock.
I'm hoping I do not get a boot-loop but think its a matter of when rather than if.

if you're on a contract then you're covered for the 24 months. Nothing to worry about.
yes there is no root. That unfortunately is the situation we are in, every brand has some unnecessary drawback or other.
Well unfort i got a sprint varient but no longer with sprint. Im sure lg wont fix mine if it did happen. I cracked my digitizer about 2 days ago so now the phone has its first sign of damage. And knowing lgs good for nothin high and mighty butts theyll tell me thats what did the boot loop. And for them hoping ill upgrade yea rite never again. Ive been using my old internation edition note 1. Just because its rooted and custom recovery. Id rather go old skool than deal with lg any more.
Plus i thermal paste every device ive owned back since my og evo 4g. So theyll know ive been in mine.
Also as for the waranty sticker mine didnt have one either

The poll was there, but was removed 2 weeks ago, possibly new one will be back. Some ppl participated and answered that they don't have a bootloop, but later they had to change their vote and that was not possible... I don't remember the numbers, but the problem is also available on H818, many people go to the Service with it
BTW, in Russia / Ukraine only 1 year of warranty, so it's going to be interesting soon Mine was bought in Poland, bootlooped, now in service

It will be interesting if it starts again. I wonder why they removed it. Should have left it as is.
From the poll here, the ratio of devices with bootloop is highest with 505, fewer with 506 then keeps getting lower as the months go on. Yes there are some that have a problem but we don't know how many don't have a problem. They are quietly happy

1 year warranty in India too. 30k G4's imported. Number of Indians who complain about bootloop on xda ? can't find any. Why.
There have been other issues with earlier models, screen problems. One guy had the phone die. he said not bootloop.
Hong kong is another and Indonesia but again they say like you many, there is some noise for a month then it goes quiet.

With the help of google translate did a search on the LG section for the word 'butlup' (short for butlupnikov ) in cyrillic and found about 24 reports.
There is no pattern, only half of those 24 mention the serial#. Some earlier serials 505, 506, 507and some more recent ones 510, 601etc. The impression you would get is any number can bootloop which isn't what we found here.
Agree with what sergei says here.
In general, a matter of luck, like in any other phone. There is more panic, which somehow affects people. I, too, this fact forced to think about the choice of an alternative, but I did not find one, considering the price and characteristics. A camera for me is probably the most important point. None of the phone for the same price no camera, even close similar to G4 camera. The only option may be a Galaxy S7 / S7Edge. But twice the cost (comparing with G4 price) immediately makes to abandon its purchase.

EDIT2: Ok guys, I *finally* got my G4 back.
LG PROJECT P1 (H815 - LG G4)
IMEI changed
S/N 505x => 602x
Repair: SWAP motherboard, software update (20D)
But would we all be subjected to the warranty? Otherwise it's not different from before.
At this point it seems like they just realized what the problem is after wrongly sending back a few units as 'repaired' even though it's still having issues.
"Customers who purchased their G4 devices from non-carrier retailers should contact an LG Service Center with the understanding that warranty conditions will differ. "
If you purchased your G4 from a third party website/eBay, it's more difficult to get your warranty recognized.. best is buying it via carrier, LG official store and recognized sellers.
Are they also going to apply the fix during the production of newer LG G4s? because if not, it sounds like all lg g4 will experience the bootloop sooner or later and will only repair it after it has happened
Yes, no detailed information about it, but it seems that they already changed the production process weeks ago and they're just late to communicate on the identification of this breakdown.

"For in warranty repair service, you must include a copy of the proof of purchase inside the product packaging returned to the LG Product Repair Center."
Well, I can't see any problem here. You need the original invoice, that's uuuh.. normal?
I just bought the g4 and sadly discovered that my S/N started with 505. Thanks god i did not unlock the bootloader. But I really want to unlock it to install custom rom. I'm thinking of sending my device to LG even if i didn't have the bootloop yet so i'll be sure not to get it after unlocking the bootloader and then having LG not repairing my phone. What do you think ?
Just use it and stop worrying, your device may not be broken as ours.. and no, you can't leave it to repair if it doesn't have the bootloop thing.
So where are all those people now who always wanted to prove not many people are being affected or it's a common thing to have problems when they first come in the market???? I wanna see their faces... I had to hear lots of things when I started writing about it. People made me believe maybe I am the only one annoying the surreal sound of the community. It makes me so happy to see this day which I was crying out loud to happen for so long.

Good to see this thread. My phone just died this night and since then is constantly hanging at boot screen. No access to recovery and download mode, no recognition by the computer (only a few seconds, then it restarts and gets disconnected) so no kdz flash via flash tool either. Just sent out a repair request to LG. Now fingers crossed it falls under warranty as I unlocked the bootloader. I purchased it in June and this is clearly of one of the first produced series which has the hardware defect, s/n starts with 505.
Don't worry, LG must repair this harware issue, no matter if BL is unlocked or not.
If you want to wipe or recover your data, try the freezer method. It works.

A lot of these 'people' don't really care or look into things until it happens to them.
Then all of a sudden there up in arms being your friend about the issue. It really only took a two second google search to see how widespread this is. On reddit there's a constant stream of bootloop posts if that's not enough proof.
Now? It's just crickets from the ones who were so keen on shooting this off as a small 'problem'. foh

But I can't do anything before this issue occurs? My s/n also starts with 505...My only chance is to keep fingers crossed?:fingers-crossed:
Yo don't complain as your phone is working great, just enjoy it and keep in mind to backup your data to microSD/computer. There's a small percentage that it will brake one day.
I remember mine overheated few times, and it may have broke a hardware component.
If there's nothing to report on your device, then you don't have to worry.
Hi together,
I've sold a LG G4 eight weeks before. The phone was unlocked via the official LG developer method and cyanogenmod.13 was installed. The phone works well, but for 2 weeks the camera does not work any more. After resetting, the camera works fine for a few hours. I have reset and reinstall the original lg software via lg update tool but the camera defect is still available. I'm pretty sure that issue is a hardware issue.
To create a warranty issue, the bootloader must be re-locked again.
Do you have any ideal to (re-lock) lock the bootloader again? Otherwise I have to pay to repair a 8 weeks old phone.
Note: I'm new in this forum. Therefore it was not allowed to open a issue within the developer section.
regards,
dreas
You cant re-lock the bootloader. Unlocked is unlocked. Its written everywhere...no way back!
I've successfully send mine for repair after applying 24V to the battery contacts (batter removed) and frying the mainboard. It was the only way to get them to fix it and it worked.

How would LG know this IMEI is unlocked? Having gone through the web process to download the needed files doesn't mean one has used them (like me).

Unless the phone itself transmits its unlocked state *after it is actually unlocked*, LG can't claim it is unlocked just because you downloaded the files.
In E.U any software modification are legal by the law, and LG can't cancel the warranty, so if you are in Europe you have no problem.

That is not true. I've been in contact with several entities to be able to know if that was true and they always said that the warranty is void. There is always a chance they don't care you have the bootloader unlocked and still fix your phone but you shouldn't count on it. In short, if you are lucky you can get your phone fixed. I'm still waiting for LG's response to whether should they fix the phone if you had the bootloop problem and the bootloader unlocked but if the problem is not that I doubt they will fix it.
What entities would that be?
Problem is that companies don't like regional warranty laws, and will often play misinformed or ignorant of them, so they will inform you about *their* side of the story.
Fact is they *have to* honor them, but won't do so unless they are made to. Which often means the consumer has to take it further, which is time (and maybe money) consuming, so, many of us don't do it. And of course the companies know it and count on it.

I'm sorry if I wasn't explicit enough. What I mean is: If LG doesn't fix your product you won't get it fixed unless you lose 10 years of your life worth in trouble. Even if you go to any consumer rights association you won't get your phone fixed before 6 months or so. Can you handle 6 months with no phone? My point being, if you want to keep your warranty don't unlock the bootloader despite the fact we are right we have no power to make the law count.
Agreed.
It's legal to unlock your bootloader in EU, but LG doesn't recognize that and they've answered me to proceed with suing them - they do not care Just go to a local repair shop - any would do, and tell them to apply 24V to the battery contacts - it will fry the mainboard and leave you with the possibility to return it for a repair. The phone acts as if it's in the Qualcomm mode - a know problem with the G4, so they will just replace the board and give you back the new one. Of course they don't know whether your bootloader is unlocked or not. Just don't tell them when bringing the phone to the repair center (duh)

can you post update please of your situation. when you get nay news about your phone.
Yesterday, my groupmates and I were presenting this VR application to our panelists. Somehow in the middle of the demo, my phone rebooted and it took a while before it actually opened. After it opened though, a few seconds or about a minute later it will reboot again and this happened a few times so I decided to turn it off. Later, when I decided to turn it on again it won't let me past the LG logo and it just keeps on bootlooping so I decided to turn it off by removing the battery and let it stay off for a while. Again when I decided to check on it, the phone won't even turn on even after holding the power button for a few seconds and trying to remove battery and place it back. I decided to check on it later again and it would boot but only until the LG logo again and this time it stays there for a few seconds and then it goes black and this just keeps on happening every time I try opening it. I even tried to do a hard reset (reset to factory settings) but only the same thing happens, the phone freezes at the "Yes" option when doing the factory reset and it goes to black after a few seconds. I even tried flashing a firmware but it won't let me do it because the same thing happens (reboots into LG logo, freezes and then turns black).
What could have happened? Is there anyway to fix this? :/
Any help would be greatly appreciated.
Edit: My phone (H815) is running MM, not rooted,

Unfortunately you are also in bootloop effected G4 club now. If it is in warranty, claim it as its board will be replaced, it is hardware failure. What is Serial Number of your G4?

Damn :/ I bought mine from an online store not directly related to LG but they have a 1 year service warranty though so I'll try that.
How do I know the serial number?

Your S/N is on the phone behind the battery. They will also need your IMEI number.
So you, just like hundreds here, and I am pretty sure it's thousands globally have got bootloop issue so there is no need to create new thread as that is not going to fix your issue as you are in the same boat just like all of us with probably your serial number starting with 505xxx.

Oh well, unlucky... I don't remember seeing any 511 developing bootloop which might be concern for others since I believe that from November 2015 they fixed the bootloop issue with hardware revision 1.1. You can add it here http://forum.xda-developers.com/g4/general/longest-running-bootloop-g4-t3386329 so that others are aware that 511 can also develop bootloop

I'm sure you'll find all the answers going through threads on LG G4 bootloop issue. Seems like the pins on the qualcomm chip get somehow loose or unstuck from the motherboard overtime (usually the 2 big cores) that why the phone is unable to boot when that happens. That's why disabling the big cores helps to boot the phone using only 4 small cores.

Problem is I bought the phone from an online retailer and all they have is labor warranty. I've also tried e-mailing LG here in the Philippines but I haven't received a reply yet and it's been almost a week.
Can removing the 2 big cores (hardware, is it even possible?) by a guy who can repair it, fix the phone?

they dont have chat option on pholippines? i always chat with them in the USA. if you have warranty callled them or chat so they can fix it . or get you a new phone.. or repaired.
not sure thers is a TOT file that disable it then root it and enable other 3 small cores. to boot.. and use phone.
not sure if you can use it with your phone i cant no support for USA variants

U cant claim warranty from lg unless u buy from them directly ...u best bet is to contact the online store n tell them to contact LG otherwise ur screwed lg will never accept warranty n fixing it via technician cost 200US$ cuz they need to replace a motherboard from fixed working g4....isnt lg phones a pain in the *** next time dont buy lg phones...

That is not correct. 12 month warranty is provided by LG for the device so he can go ahead and get in touch with LG. As long as he's got proof of purchase that's all they ask.
I have unlocked my bootloader and rooted my device (H815, s/n 506*, EU); and therefore LG does not want to repair my LG G4 under warranty.
Can I repair it myself, maybe replace the motherboard or something? Does anyone really know what the exact problem is? Where should I get replacement parts?
You need to just put it back to stock then call back and don't mention that it was ever rooted. It doesn't matter if it was or not anyway.

Mbs are about 200 dollars american. A little pricy in my opinion but one of the most simple setups ive ever seen
You can try all the methods mentioned above, have it fixed in a repair shop (they'll re-solder the flash chip) or even put it in the oven. But it won't help. It'll only work temporarily.
yep !Buy new mainboard and then replace .
BUt EU 2 year !!
If well know hardvwre issu i think lg don't refuse repair!!!Kick the frakking table mate good luck! see this:

@kabirjedi unlocking your bootloader do indeed void your warranty. He cannot do anything with it and link you posted is about installing CFW or rooting fw alone.
From my observations the processor is the only problem, more accurately, the two faster cortex a57 cores. Some how they broke hence the phone cannot be booted up as it returns that them 2 cores are unavailable. Thats why this tot method works.

Congratz on your 666th post
I agree with that it SHOULDN'T void warranty, but sadly it does and AFAIK in Poland no one managed to get it fixed for free with unlocked bootloader, even if this EU law was mentioned. I dont know how they manage to overwrite Eu laws but they sure know how to confuse the customer and leave him with 1600PLN bill (price for repair outside of warranty)
Luckly I just had unbranded FW + root + xposed without having bootloader unlocked so they replaced mobo without any problems.
Anyway I wish you best of luck in your case, OP. Do what @kabirjedi suggested, perhaps you will have more luck in your country
the way i see it. is no matter what phone is defective. i dont think a phone because of unlock bootloader will bootloop. it will brick for sure so they are very different things . but LG sees this a potential to make bootloop more easily affected. thats non sense.. theres phones like S2 running great G2 with bootloader unlocked running great.. this is hardware no sofware... maybe heat plays a role...only way i see it can trigger it is overclocking it... but if you unlock and debloat phone should runs better with less apps that are crap.. one exmaple is disable logd.. that helps the CPU.

Time and time again it has been confirmed that this has nothing to do with bootloader being locked or unlocked. This is manufacturing issue that was firstly acknowledged when they recalled all Sprint models with 505xxx S/N but other providers/suppliers ignored it and carried on selling faulty devices just to meet sales targets. Make sales first and worry about the potential issues later is the common practice nowadays. For the suppliers it was always the possibility of either developing the bootloop or not. For LG replacing just motherboards still means a sold device at the end of the day. And don't worry in this competitive market companies do anything to meet the sales targets... Headaches for us -> small inconvenience for LG.
On reddit people suggested resoldering the CPU, I might give that a shot.
Hi, just bought a second hand g4 with serial number starting 509 will the phone possibly bootloop? Also the phone is the Taiwan model and I currently live in the UK, will having the Taiwan model cause any problems? Thanks
It may Bootloop it may not. There is no definite answer. You may have problems with a non EU model in the EU. They may fix it or may not. You have to ask an LG service centre about this.

If you ask if 509 is prone to Bootloop issue I think it is. Most bootloops happened on 505 though but the general consensus is the newer G4 you have the less chances for bootloop. Again there is no definite answer. We do not know the dirty details. We don't know which S/N is safe and if LG fixed the problem and from which S/N and after they did. We purely rely on public reports to draw conclusions. Up until now 6xx seems safe with only 1 or 2 ppl reported a bootloop on Reddit. Just make a backup and keep your data on the SD card. If you get a bootloop contact LG. They seem to be aware of the issue and fixing all broken phones even out of warranty some times.

I'm in the UK and have the same problem - a bootlooping TWN H815. It was purchased used last year, so no receipt or warranty card. I was wondering whether you had explored paying LG for an out-of-warranty repair? At this stage I'm looking at the best way of cutting my losses.

In US cost of repairs alone is 200US$ cuz of morherboard replacement either that or which u can get a used g4 at the same price so even if ur bootloops there is no point of fixing it....all i can say for u is to wait for atleast an year after the bootloop so the prices fall down for repairs....there is no way u can send it to taiwan also there is no warranty n recepit thats only even if u have a friend there...
Avoiding heat
Hi all am in same boat. Got a EU H815 an 506 hw1.0 and until a week ago had never heard about bootloop issue. I've had unlocked bootloader, rooted with custom ROMs nearly whole ownership and as a result have never had any heat up issues. After reading 100s of pages of the issue my conclusion is that it seems to be heat that affects a soldered component which eventually fails. So based on this theory I'm using Kernel Adiutor to control the throttling when CPU temp gets >55degc. It is only an educated guess but does seem logical. Hope it helps others

Seems like the issue calmed down over the winter in the northern hemisphere. And now that the summer is in full bloom people are looping like crazy. Im hoping between being almost as far north as one gets in usa. So like 85 far. Is blazing here. Plus me doing the thermal mod im keeping my device cool enough to make it as i have no waranty so a mb replacement costs me about 200 dollars american.
I have a s6 and a couple other mid range devices. I wont hesitate to toss my g4 in the trash. I got mine on a trade in from my g3 i only paid like 150 for my g4 so nope not me. Unless i get one cheap.
If this was an automobile this would be a recall i dont understand why these devices arent recalled.
I saw a news cast talking about how they make devices so cheap and breakable "for the economy" why would u buy the newest devices out if your old ones are running quite perfectly they say. So this is for economic reasoning. So go ahead lg keep making s****y devices i will buy a new one but not from you.
Yea i want a g5 but i wont give more that 100 bucks for it in the fear of failure.
Like i said keep it up lg seal your economic fate........

they are all bad as far as i know. And yes, nobody has this phone as its later revisions bootlooped after warranty and its more expensive to repair this piece of crap than what it is worth even after repairing.

I have a phone that's never bootlooped
