I want to buy tomorrow the LG G4 but heard today that the phone have the bootloop problem, there is any way that I can check the phone in the store? and not wait until it die?
the about setting or something , and know if the phone that I'm buying have the problem or not?
It happend suddently without reason ,with all configs (locked/unlocked...root,no-root...custom/stock...mm lp ...)
it seem that all models are concerned,principaly s/n 505 ,but lots of 506 ,507......600,601......have been reported.

I thought that all the 600+ models are fixed , I'm wrong ?
Yes, you are wrong. There are reports with 603 bootlooping, that was the replacement for a bootlooped 505

From my experience my defected unit that got bootloop and replaced sometimes when I plug the charger to the port., it detected as charged with usb it show [USB Charging] I forgot what's the precise word.
So my 507 is a ticking bomb. Waiting for it to happen.

So far there is no way to tell if you have an affected device. The early serial numbers are the reported culprit, possibly due to their age. It seems to be around six/eight months before it hits. Device use may or may not play a factor.

You have to comb through the bootloop thread here and a few others at other sites but there have been a few reported. At least two of the reports do come from devices that were repaired and returned.
Pretty sure 600+ are fixed. Its very rare to see those go bad. Its not worse then any other phone.

Move along....
I don't want to risk spending $400 on a likely-to-get-bricked phone. I'd like to buy the H815 version with warranty. If I get the bootloop problem after buying the phone, is it possible to fix it with warranty?
No.

yes,you can fix it with warranty(unless you don't mess with the phone). So far only 603 has been reported for bootloop issue. No idea about others.
602, no problems so far..
.
I don't think any devices are 'safe'.
The problem took between 6 - 9 months to appear for most people.
There's no possible way any 602+ users can say they have been using the phone for 9+ months without this problem.
My H815 serial number start 509 release date 16 Sept 2015 still going strong. Currently running H81520D stock firmware and phone unlocked but not rooted. I have been on several other incl CM13 and no problems so far.

Yeah, I agree. As far as 6xx series goes, not many people have reported but its too early to say its safe. But since this issue has been known by LG so they might fix the issue on all models which are in production. Hoping for the best since I have already ordered it!

Hope you get a recent model. i've had mine 2 months and its a 506.
Has LG figured out the real cause behind this problem? If some of the new phones have actually shown bootloop issues then that should mean LG failed to fix it.
Also, after fixing it from warranty, is there any possibility for the problem to occur again?
How many times will the warranty fix my phone?

Same here. Got a 603 after I sent in my 506 for repairs. The 506 was running strong and bootlooped out of no where so that fear is still in the back of my head.
Okay, I'm getting a LG G4 tomorrow. I was quite sure that If I get one manufactured in 2016, I won't have to face the bootloop issue. But then I heard people complaining about the issue even with the ones' S/N starting with 6xx. I also heard that it's due to a software issue not hardware like the previous ones.
So I was wondering what LG has to say regarding this new software problem? Should we expect a fix in the next update?Or, will I be safe if I get the phone and downgrade it to Lolipop from Marshmallow?

I am talking about the new ones. The 2015 ones had a "loose connector in the motherboard" which caused the bootloops but LG fixed it in their new phones but another bootloop issue arose but this time it's due to the new Marshmallow version of Optimus UX

are you sure about that they 'fixed' it ? Recently a phone with 603 s/n reported for bootloop failure. I'm not really sure that's a software problem caused by marshamallow because they will have know it (due to their tests on phone before releasing)

I don't about the phone you're talking about but my 509 was repaired with a 603 motherboard that only lasted 3 weeks before getting the bootloop issue itself. During this time the phone was hardly used as I was waiting for Vodaphone to unlock it and I don't flash my phones.
Hi, LG changed the motherboard of my lg g4 in 3 days. I had bootloop problems with my old s/n 505. That's ok, but my new serial number starts now with 610. It's good now? Anyone with new problems s/n 6xx?
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........

Hi, my G4 had bootloop recently, motherboard was changed under the warranty. New motherboard was made in 04/2018. Is it known if newer motherboards still have a bootloop issues?
I cannot found any relevant informations. Maybe because nobody already have this old phone

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 my bootlooped G4 in a drawer since 1 year ago.
I have a phone that's never bootlooped
Helio guys, I'm planning to buy a aecond-handed G4, but I've seen that there's a major issue with it, a bootloop problem caused by the motherboard.
My question is, Did LG repaired that problem on some new G4 models, I saw that phones starting serial number with 505 are the ones that will fail
Thank you
hi,
if you have a phone with serial 50x, then you need a new motherboard (phone) with 6xx

You have to ensure that the serial begins with 603 or higher
also ensure that you do not buy a phone with an already replaced mainboard! Means the phone should be produced in 2016

1. let him pull out the battery and take a pic of the serial there (this is no guarantee though because if it was in repair the sticker could be replaced as well)
2. please consider to buy a h815 international(!) or h811 because only these both can be unlocked!

Just my personal experience and opinion. There are no guarantees or official statements anywhere.
experience means:
I own 2 h815 and both having serial 603 and both are in heavy usage because of development and they are still alive.
regarding the background of my opinion:
LG acknowledged the mainboard issue in January 2016 (http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/) and so we can assume that beginning from then it should be fixed for any newer devices then that date. 603 means March 2016 so I think that beginning from this charge it will be safe. again no guarantees nowhere.

he should get a tmobile h811.
well i can vouch for that too.
after readings lots of complains you can see the pattern that most 5xx failed. and keep failing. some are lucky thoug.
LG claims that from 511 upwards its fixed . but reports are different . only a few 601 and rare 603
it doesnt mean it wont theres no way to tell but chances will be low.
am running a 601.
I saw a poll somewhere (might have been here on xda) showing bootlloop data by SN and as expected most of the bootloops were on 5xx devices. But there were a few problems even on the newer devices.
It seems logical that refurbished units in the past 6 months or so should hold up. At that point LG had determined exactly what the problem was. However, I have read threads on folks who had their G4's replaced with refurbs multiple times. I just think it is a gamble when picking up a G4 because you never know if it will last, these things are like ticking time bombs. It reminds me of the RROD Xbox 360 problem a few years ago. Best bet is to get a warranty.
My personal experience was a G4 505 purchased on release from Verizon June 2015, bootlooped October 2016. Verizon replaced with refurb and SN 506 which has been running fine, no evidence of bootlooping.
