yes under the battery is the SN and imei, and it says it was made on 05/15 , the imei of the phone is the same of there...

is there any way to see if this phone was refurbished or tmo had repair it for bootloop before i got it?

i got it 3nd hand and the seller(a friend of mine that has a small store) imports them from US used so no chance to know what has been done before from him... just a thing , the phone was like knew , no signs of usure, super super clean for that i decide to get it there... saying the truth i didnt have problems with the phone, no heat no lag nothing, as take i put on custon rom and go....

now reading about bootloop i dont know what to do, i can sell it for same price i got it or keep and risk?

thanks
[G4 General] Minto107:
As far as I know they change the WHOLE phone but they can put it your battery and back cover as it's simply removable ;)

In my country there is a joke about determining how old an AXE is:

Count how many times the handle and blade have been replaced.

To me, if you have a motherboard dated i.e. 508, (August 2015) this is the age of your phone, no matter what has been replaced after/before.

Serial 505KPHG

Purchased when it first came out in the uk (May 2015)

Starting to get lcd burn but no bootloop issues
[G4 General] gazoox:
Didn't know 505 bootloop until it catched my G4.

Bought July 2015. SN505. Last Friday it died, stuck in bootloop. It's rooted, mainly to deal with purple pixel rentention /display wearout, started in March-2015.

Bootloop also with big cores disabled.

I had this also similar case some months ago. It froze, bootloop. After recover backup it worked as normal. Trying warranty. Hope best.
[G4 General] welder73:
I have that screen retention too...

How can I solve that problem?

Now you're incoming Theseus' paradox...

:p;)
[G4 General] digitall1982:
I had sn 505 and died after one year without any problem, and also screen got some burn-in in status bar area when is hot.

I have warranty and I tell that to service guys and got new motherboard sn 611, and new front housing including new screen and all. So I have new phone now :D

Only battery and back cover are old.

And one thing that I noticed on my "new phone", battery is better now and it working little faster! Maybe old motherboards draining battery faster because they have serial fault...
[G4 General] gazoox:
Got my phone back from LG repair. Took only 6 days. Board replacement (yeah!), LCD has not been exchanged (unfortunately, purple pixel are still available).

Serial on case is still 505. Maybe just label is not updated... New board is not rooted.

Anyway, thanks LG for the repair.
[G4 General] resinis:
Didn't make it 6 months :silly:

Bootlooped today. I put it in the freezer, and it did come back to life, but not long enough to pull my pictures off it

not a big deal, all my important pictures were saved to google keep, but still.... that was a $150 phone dammit. oh well.

I just bought a used g5 on ebay for $175. We shall see how long this pos lasts :fingers-crossed:

It takes courage to going again with a LG device.
[G4 General] TheMadScientist:
Mines pat 18 months bootloop free pretty sure a 511 serial
[G4 General] resinis:
I dont know.. I guess.. but their design is the best. Well I haven't seen the guts of the G5 yet, but the G2, G3 and G4 were all super easy to work on. It's really sad the G4 had the bootloop issue, because I could have easily stuck with it until the G6 hits $200 used in about a year.

Hell I would stick with my G3 but the speakers (earpiece and external) are lacking, and I work in a loud environment. The g4 was a huge upgrade there.

Im pretty sure I killed my g4 with wireless charging too. I knew the bootloop issue is tied to poor soldering on the soc, which is exasperated by heat. Wireless charging caused the g4 to get hot over a few hours... I knew it, and I still did it. Im sure thats what killed it.

No wireless on g5, but at least its usb C so it's easy to plug in. I dont mind plugging in my phone, but I have that problem where I ALWAYS stick it in wrong the first time, and it gets incredibly annoying. Will be nice to just stick it and flick it. Plus, wireless charging on g4 was godawful slow anyway. Sometimes it would take a few hours, sometimes it would take 8. If I ever needed a quick charge I would just swap in a new battery anyway.
[G4 General] Minto107:
Used? Let's place bets ??? 3-5 months? Why did you go for LG again? You could go for something as good as S7

yea samsung has a great reputation. their phones dont just die on you, they try to take YOU out with them!

i never buy new phones. f that. i did that once, and the thing still died on me within a year (g2).

truth is i work in an industrial factory, and i beat the crap out of my phones. theyre going to die on me, its just the nature of how i abuse them.
[G4 General] tmihai20:
Mine is getting close to 12 months, 604 serial number. I will not go for a LG anymore, mostly because of the update distribution policy on my G Pad 8.3 and my G4.
[G4 General] TheMadScientist:
ill second that i put one of the charging coils in my ls991 and its so slow usaully take 4 to 6 for me and compared to all my samies . g4 gets so hot too
[G4 General] Minto107:
My 602 also is running still, and I'm also mad at LG for ****ing with us about Nougat... If OnePlus will improve its camera quality, good bye LG then but I love camera UI
[G4 General] tmihai20:
I want audio jack and microSD card. OnePlus, no matter how good their latest phone will be, is not enough for me. Let's see how Nougat looks when it will be leaked.
[G4 General] niftium:
505 serial, purchased just after launch - no bootloop (yet).
[G4 General] Minto107:
Yeah I also wait for Nougat. No SD in oneplus isn't that bad when you have 64GB+ of stock storage. Im certain OnePlus won't remove jack as it's a deal breaker for some people and unlike Apple or HTC they care about their customers

Good to know! Fresh info on the older bootloop free G4!

Thanks for the on-topic info.
[G4 General] kessaras:
july 15 here too.

im one of the happy users. My g4 is working flawlessly.

Also i think there is no need for such a thread unless LG pay you to advertise their products.

Second reason: if there are 50 people with a bootloop problem , that doesn't make any change. More than a billion g4 were sold until now. 50 people do not change the fact that the phone is good.

Right ? I don't think that we have to go to a debate and count who will win
[G4 General] 3ig:
506 bootloped last week. It was running for 1 year and 10 months. My carrier repaired it under warranty despite the unlocked bootloader. Running a 702 motherboard now :D
[G4 General] danny_wasp:
I'm now on my 3rd H815, all within 16 months.
[G4 General] EPa:
You make no sense:

First you imply this thread could be an advertisement for LG, then you say that bootloop free G4s are no big deal because only a handful bootlooped and the phone is good (so not much of an advertisement).

You say there's no need for this thread but you took the time to post info along with your view that the thread is pointless. Do you do that in all threads you find pointless? Must be a handful..

LG paying me? For this? [emoji2] [emoji2] [emoji2] Ha ha I'd wish!

No game to win here just info.. If you think it's pointless simply not bother.

playing jenga now. game of words.

you understand very well but you say you don't so that i answer again :D

smart :D

i won't answer. this can go on forever haha
[G4 General] EPa:
More discrepancies..

Jenga a game of words?

I said I don't understand? (I said you don't make sense, that's different)

I want you to answer? (why on earth would I ? )

You won't answer? (in your answer ? [emoji1] )

Again, just don't bother in this "pointless" thread..

If there was an option to down vote the posts on XDA this post probably would get quite a few of them :) just love the ignorance and total disregard of the facts.

505 korean version bought on Lunch day. Working Flawlessly hope I'd make it to Nougat before I switch to Note 8
[G4 General] kessaras:
ofc . this thread will get many. you are all good spammers.

just like the thread about "No nougat for lg g4". As a matter of fact there were 2 of them.

Both flooded.

enjoy talking ballsh...s all day. besides thats what general section is for.
[G4 General] br0adband:
Hate to be off-topic but, they're making new motherboards even now in 2017? I'm reading that 702 as February 2017, am I just being ignorant or is that actually correct? Reason I ask is I have a chance to get a 505 model pretty cheap and I was gonna "white lie" the purchase date with LG for a warranty claim if it does die so I'm curious about that 702 date code being legit.
[G4 General] raptorddd:
601 hundred of flashes. sometimes daily..:fingers-crossed:
[G4 General] Minto107:
Actually that bull**** was part of that we will get Nougat so complaining in public places like XDA or reddit can make difference so let's all of them complain and spam. It might give them a lesson they deserve
[G4 General] 3ig:
Yes it's February 2017 and it's legit. I've already seen a couple of those boards.

The phone feels less hot with this board and performance in static benchmarks is better.
[G4 General] pepo930:
Just got my G4 back from repair. New board is 701, old one was 506 and it survived for 1 year and 5 months.

Antutu score = 46234. I dont know how much I used to get before.
[G4 General] gruiz3:
Sn 505 H811 Brown leather 7/15 no boot loops. Currently running lineage os and 10k mah battery. So happy mine was solid.
[G4 General] br0adband:
Found a second G4, a T-Mobile H811 model, a few days ago for $15 on craigslist (yeah, a score, I know). Works fine so far, the manufacturing date shows May 29 2015 so, just shy of 2 full years, serial 505 and it's registered now with LG in case it does up and die on me at some point over the next few months.

I kinda almost want it to die so I can send it in and get one of the new or newer 2017 motherboard swaps so it'll potentially have the proper fix hopefully but, as long as it works I'm good. Unlocked the bootloader so I'm experimenting with Lineage off and on to find out which particular setup I want meaning either stock with the Llama Sweet Kernel (since T-Mobile just dropped the 20v update yesterday) or go Lineage from now on (with the same kernel, actually).
[G4 General] maxxx83:
Hey guys.I want to buy G4 but i know about famous motherboard and bootloop problems.What serial number is without that kind of problems is anyone knows?Is SN5 or SN6?
[G4 General] tmihai20:
It should not have SN starting with 5, it should have a SN starting with 6 (mine is 604) or even 7.
[G4 General] draskome:
Mine (506) just went to bootloopland few hour ago, after 13 months :eek:

Fortunately, it is under waranty with Telenor, so I hope that mobo will be replaced with the one that is boot-loop resistant - if any ..

Just for the record, phone worked flawlessly for more than year, and just yesterday I've noticed very small, bearly noticable lag during normal operation, and my battery started loosing charge more rapidly than ussual..Today I havent used phone much, and after one phone call, it just went to boot-loop.
[G4 General] heroutm:
Hi, it seems like my LG G4 with 601 SN: 601KPXV942378 bootlooped today at night (est. time from manufacture 1 year(s) 4 month(s) 1 week(s) 2 day(s) - (manufactured in January 20, 2016). My phone had yesterday at 23:50 aprox. 15% battery, I came to phone today at 8:00 morning and battery was at 0%. I plugged in charger, turned on phone and it is still booting, nothing happens. Phone is aprox. 1 year old, still like new, even with original screen protector. Still in warranty.

**** YOU LG! :mad: :mad: :mad: I won't buy anything from LG anymore after this. :mad: :mad: :mad: Aggrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!!!!!!!!!!!!!!!!!!!!!! Burn in hell. It seems like "planned obsolescence"!! Consumer society and pure capitalism. Nobody buy from LG anymore! All things will **** up one day!
[G4 General] coldspring22:
Sadly, all early versions of LG G4 will go into bootloop sooner or later. The culprit is the defective expoxy underfill used between SD808 and 3GB ram chip layered above it. Thermal expansion of epoxy will break the solder bond between the chips, causing bootloop. That's why all the reflow attempts also fail. Only way to repair is to desolder the 3GB ram chip and scrape out the epoxy underfill, reball/solder back 3GB ram chip.
[G4 General] kouzelnik3:
So it means every single motherboard will fail no matter which S/N it has? Even it is 505 or 704?

Or I didn't understand correctly and the only motherboards that will fail are that early ones? And - what means that "early"? To which S/N is it possible to fail?
[G4 General] br0adband:
Actual heavy usage is what kills the G4 and the other devices suffering bootloops, it's simple physics more than anything else. The solder they used develops microfissures in it (same stuff that happened to all those defective Nvidia GPUs years ago): when people really go hard on using the devices, they heat up, then when they're done they're allowed to cool down and this heating and cooling aka expansion and contraction over and over and over again causes those microfissures aka cracks to develop in the solder and at some point it gets bad enough where not enough or not electricity will pass through the connection to keep it working properly hence, bootloops and shutdowns and dead devices.

No different than pavement developing cracks and potholes - it heats up and expands, it cools down and contracts, over time that just worsens and voila, it's not gonna work as designed.

There's no absolute certain test for or diagnosis for the bootloop issues, suffice to say if you don't hammer your devices with hours and hours of any activity that requires it to max out the CPU/GPU for temps and then it cools down then you go right back and do that over and over again, it will die on you sooner than someone like myself that never plays games, never really does much of anything that maxes out the CPU/GPU on my devices.

I know it sucks that this happens and continues to happen but the G4 is 2 years old now - mine has a date code of May 29 2015 so it is literally 2 years and 1 day old today and it's still going and I have no reason to expect it to die anytime soon because of my usage patterns but it could, there's no denying that, at any given moment when I least expect it just like anyone else's G4 could or one of the other devices from LG known to suffer the same aspects because of that solder.

All you can do is use the device till it (more than likely) dies and then move on, really.
[G4 General] coldspring22:
I don't think it's heavy usage. My LG G4 died even though I disabled big cores and ran no heavy apps. Meanwhile, my samsung sch-i730 from 2005 is still chugging along after 12 years of usage! The problem lies in the defective underfill used by LG between SD808 and 3GB ramchip. If LG had not used this underfill, there would be no bootloop epidemic.
[G4 General] heroutm:
I must agree with you, I barely used my G4 and it is still like new phone. I wasn't playing games etc. I was just calling a messaging most of the time. I think every LG G4 motherboard will suffer with bootloop (no matter which serial number it is). LG knows about the problem and they don't care. They are still manufacturing defective motherboards. There is already lawsuit in CA.

[G4 General] draskome:
My phone just got back with replaced motherboard. Motherboard version is 705, and it is produced 8th of May 2017, so extra fresh peace of hardware. Considering usual pattern, I hope that this means at least one year of usage before next bootloop :D :eek:
[G4 General] Loulou-13:
hi !

update of my previous bootloop-free feedback here :

i have had bootloop at the last week-end !!! sh***... :(

i have disasembled for to extract motherboard ==> go to the HEAT kitchen oven after preheat ( 200° C during 5 minutes30 second....take the MB on the ovenwithout the 2 metal plates extracted before ) ===>reassembly carefully ...

===> and my phone work fine now ! incredible... :eek:
[G4 General] heroutm:
It will work only for a short time and damage will occour again.
[G4 General] Loulou-13:
Hi ! ;)

YESSSS !!!!!! :mad: damn sh** !!!!!!! :mad:

Work during 4 days.......and bootloop again !!!!! Pfff.....

I have and another phone now....i repair this G4 (waranty) and imediately sold it !!!! Good bye LG ...

It's a real pity because this G4 have exeptional photo quality,great battery life,good design of lg firmware.....and i love SimpleGX kernel...
[G4 General] heroutm:
That might be a reason why we don't have 7.0 yet. I think that all LG G4 phones will die until they release 7.0 Nougat. They know about the problem and they are doing nothing! They are still manufacturing defective mainboards. I hope I will get money back and I won't buy anything from LG anymore. If not, I will make them a great PR.
[G4 General] coldspring22:
Yes it's too bad. I also really like LG G4 design, back button layout, knock on etc. 16MP Camera is also still great even now. Also LG G4 is the easiest phone ever to disassemble. Too bad LG had to use defective underfill which completely compromised otherwise a great phone.
[G4 General] raptorddd:
nougat or MM or LP either one will bootloop no matter what it isnt software related. and nougat will be released.. that doesnt make sense at all.
[G4 General] Goatville:
I've got a H815 SEA (Singapore) manufactured 510. It bootlooped about a month ago. No warranty at all. The bootloader is locked (SEA never got unlocked).

My question- is there any point contacting LG and trying to get this fixed? Some people online were mentioning LG was fixing some devices out of warranty free of charge. The potential complication is that I live in the US but my G4 is a SEA variant. I tried contacting the US LG service and they said i'd have to ask the Amazon seller to determine the proper LG branch to contact. I might try again and see if I can escalate. I'll try contacting Singapore support too if I have too.

Any hope for salvaging this mess? Advice would be appreciated. If all else fails, I guess i'll have to hope something comes of the class action lawsuit.
[G4 General] Loulou-13:
He want to say that LG is satured,submerged by bootloops feedbacks with warranty ....and i don't think that they want to release N (spend energy and money with devellopers for a general defective devices) ,it make sense ....

But if they decide to upgrade ,i think that it's a bad idea because too much people abandon their G4 and he is not sold any more...a big commercial failure.
[G4 General] raptorddd:
i see but still we would get it..:fingers-crossed:
[G4 General] heroutm:
You will get Nougat only if your and others LG G4 around the world survives. I doubt about it. :laugh: :fingers-crossed: :good:
[G4 General] raptorddd:
i usually flash every week. when turbo was around i flashed daily or every 2 days .had this phone since jan 16.

i just change roms like evry week. am saying its been alot of stress on my phone. flashing and first boot gets super hot. i even KDZ it. then flash rom.
[G4 General] Goatville:
Followup to my above post-

I called LG's support line, US branch. I only had to tell them the phone wasn't booting and they immediately mentioned the word bootloop by assumption (guess they are getting extremely common) and agreed to help even with my no warranty SEA version. Though she said they'd be sending me a new US carrier G4 instead of repairing my H815 SEA version. They're not charging me for anything apparently.

Now I still might end up hitting a snag. The original LG battery failed and expanded enough to actually pop off the back cover. Given the fire hazard involved, I disposed of it immediately. Official LG batteries were $40 at the time, too pricey compared to higher quality third party ones. Got a TQTHL instead and it works great. But i'm concerned that this may impact my ability to get service. The LG rep said she didn't know how the service center would handle the situation, though suggested I try sending it in anyways with the replacement. So i'm including the replacement battery and a note explaining it. Hopefully they will be accommodating, we'll see...
[G4 General] heroutm:
I don't know how this works in country, but our justice allows us to unlock bootloader, root, install own software and so on. If phone damages somehow, company you bought phone from must prove that your software, your modification or your new non original battery caused that issue (which is bootloop). I I think that bootloop issue is not related to root, installing own ROM or using non-original battery. :p It's caused by poor build quality on motherboard because LG wanted to save and earn ass much they can. Guess what. I bought also original LG Crystal Guard CSV-100 cover for my LG G4 Titan and its corners were damaged after one week. Corners were simply cracking..

I hope that lawsuit will change they their mind and they will start repairing all devices even with expired warranty or they will offer to all LG G4 owners money back or new, non affected phone. (Btw. all new SN mobos - even manufactured in 2017 aren't bootloop resistant). They still changed nothing. :rolleyes:
[G4 General] Loulou-13:
Good news !!!!! I didn't have see internet for nougat update before.........but recently, many french articles confirm that there will have N update for lg g4 h815 on some weeks ....
[G4 General] raptorddd:
it will LG said V10 on Q2 AP/MAY/JUN its already released for korean was released on may.. its been more then a week lets see how long it takes for rest of world to get it.. then Q3 that beign JUL/AGO/SEP so they say v10 and G4 is similar so maybe they just do minor modifications. and we might have it sooner. or my give is AUGUST fpr korea. then maybe SEP.OCT for rest of world :fingers-crossed:
[G4 General] roshandes:
hello team,

i got a good offer on New H818P Dual Sim model. just wanted to confirm whether i should buy it or leave due to this bootloop issue.?
[G4 General] arvarobert:

Exactly the same thing as yours! Threw the phone and decided to get an S8+. Never getting another LG no matter how enticing the new ones are.
[G4 General] kessaras:
haha , all of us that post here , in a few days or weeks we will post back that its dead.

Mine now is at the edge of the cliff !

its sensors started to freak. When i hold it in portrait it thinks i hold it in landscape and reverse. The orientation is always wrong :D

i guess im gonna kiss my g4 bye bye very soon !
[G4 General] DsturbD:
So I'm probably gonna jinx myself but I have a 505 h811, got it in June 2015 and have had no issues at all. Don't know what people do with their phones to get a bootloop. I play games, surf, take lots of photos and vids...maybe I just got lucky
[G4 General] Mr.Bombastic:
I am still waiting... SN 508, bought in January 2016. I have 3 years of warranty (2 standard + 1 extended). I hope to get my money back till then.
[G4 General] maxauvy:
Hi there!

H815 here, bought in decembre 2015. Started to bootloop about 2 weeks ago...

Just got it repaired by LG for free, but I'm gonna sell it (probably) as I now own a OnePlus 3T. I'll surely miss this phone, the usability was great, the slightly curved screen/back too...
