From what it seems no g4 is safe. From what ive read even the g5s are suffering from this bootloop to. Several people said that ic power managment is the problem and mother board replacement are the fix. Now i dont know how far all of this goes as i have a suposed safe model and only have had 4 months.
But from a longtime lg user id got with another manafaturer. Such as a nexus.

Suposedly they are. But. Many claims that even the refurbs. Claims that the one that lg repairs. Bassicly. Rumors are no g4 is safe.
Your best bet is to buy a refurbished one which already had a motherboard replaced...just ask the seller whether it is repaired
Sent from my LG-H815 using XDA-Developers mobile app
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?

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.
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.

yes theres a high chance it may bootloop.. and no UK wont repair your phone.. you must shipped to the country you got it from .. i say return. and get a phone with 6xx serial number.. there less reports with those serial numbers..

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........

I cannot found any relevant informations. Maybe because nobody already have this old phone

Hello everybody,
I want to buy LG G4 dual sim smartphone. I hear that it has bootloop problem. I want to ask all of you. Should I buy it?
the bootloop problem is only on S/N:505 and 506 motherboards. You should check before buying if its 6XX then you are good to go.

I never had heard about a 6xx having a bootloop. I own 2 h815 with 6xx serial do you have any prove for that?
Tbo there will be no guarantee and as raptorddd said make sure you get the invoice with it. If the device has no guarantee anymore the chances are good (which is bad) that it is a 5xx device.

go to the reddit thread read there, go to the thread here G4 bootloop and youll see. the latest ive read was a 604 from some guy in russia. from pdnet forum. i have read people reporting from 601 to 603 just one 604. i have not seen or read a 605.
tbh I was considering the G4 only because I found a used one for cheap. Seeing the risk there is in buying one, I'll hold on to my SGS II for a little longer and get something like a OP3 later

Hi, I was recently thinking about changing my phone so thought of buying the LG G4. A guy near my place is selling it. I have also heard about the bootloop issue. Although the phone was working fine on his shop, should I still buy the phone? Are there any special conditions under which the phone goes into the bootloop so I can test it either using a stress test tool or playing a demanding game before buying? Please, I need some help!

from with serial number on back starting with 601 are less likely to bootloop the higher the number the better. lower then be cautuious.
if you dont care LG not giving nougat officialy. and poor battery. go ahead but also make sure its one of the unlockable bootloaders
search for list of lg g4 that can be nootloader unlocked.
if all okey go ahead has nice camera and unofficial beta N its nice. but official would be better.

Read the bootloop fix it list in my signature.
Buying a device which can be unlocked is absolutely necessary to fully enjoy that phone plus you can do some adjustments regarding bootloop only when unlocked.

unlocked bootloader you can flash other roms stock based or aosp.
you can install kernek and tune it for performance or battery.
its unknown if it will bootloop but is less likely to happen. from 601 upwards.
also see wht my friend steadfasterX says read hes the man. he knows more then i do.
as long as it is 811 or 815...and 601 or newer serial number...its still worth to buy it
No. I haven't had bootloops on my 602 but have still had problems.
No knock on to wake. (replace screen to fix)
Micro usb port worn out and can only be replaced be re-soldering.
Random notification led blinking. (restart wifi to fix)
No updates.
Still could get a bootloop.
How to determine if phone bootloader can be unlocked? thx
