LG G4 motherboard problem - G4 Q&A, Help & Troubleshooting

Hello,
I am using LG G4 dual SIM version in India since june 2015. Suddenly few days ago phone refused to start, it was dead. Service centre person told its MoBo problem. Since its not available here, I will be getting new piece under warranty.
I am really wondering why there should be an issue with motherboard of new phone?
What precautions to be taken to avoid such incidence in future? What could be the basic cause? Any thing related to charging or power fluctuations?
Kindly help.
Regards

Is serial number 505?
Sent from my LG-H815 using Tapatalk

Yes, its serial number which begins with 505 KPCA061251.

Hi,
Since I will be getting new hand set as replacement, should I ask for set with serial number other than 505? OR this MoBo issue was specific to 505 manufactured in specific time period?
How to proceed? Hope I wont face such issue again.
regards

Are all LG G4 with 6xx serials safe?

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.

Bootloop still a problem?

I was looking into buying a new phone, something with an unlockable bootloader and semi easy to root. I came across the G4 and it looked pretty promising. I was most likely going to buy it then I found this issue with the bootloops. It seems like a fairly common problem with the early models of the phone. I was wondering if I were to purchase a G4 now if it would still have the same problem or it has since been fixed. I couldn't find any recently updated threads on the issue so I thought I'd come over to xda.
Thanks!

lg said its been fixed. but member here have reported bootloop in new ones as well.. and since the 505 where the ones beign bad.. that means that it takes like 7-8 months to show up.. so new phones.. we need to wait till they reach those 7-8 months

It doesn't matter whether your model was European. It all matters when the device was manufactured. What was your serial number? 505xxxx?
My phone was producted in septemmber 2015 does my phone will have bootloop ?

theres a 95% possibility it will..
oct 2015 is suposeldy good. Sept 2015 and earlier are highly prone to loop.
And hardware revision 1.0 is bootloop prone and 1.1 is again supposedly good also. But as raptor said 7 or 8 months seems to be the magic number.
Ive actually moved on to a diffrent device and pit my g4 up for fancy ocasions lol. Lg k7 real low specs but unlockable bootloader.
So this will be my first and last lg phone

i dont understand.. why i have 601, but on HW. 1.0 ?? makes no sense.. unless they wanted to get rid of all the 1.0 MB.
Thats weird. Mines a 1.1. Dont know the serial num but its 10 2015 so mines suposedly the first line that were good.

I can find a straigh answer where serial num is. If i go off dec num xxxxx508xxxxxxxxxx is the only 50 type number anywhere thats straight off my box and phone. Is that the proper way to read serial or is th 50 or 60 number somewhere else. Like i said im usind the dec as whole serial num

Welcome to the sinking boat. If your phone is still under warranty then go ahead and raise RMA with LG to have the motherboard replaced. The warranty is actually around 15 months. I bought mine from Amazon in Germany last July and my phone went into bootloop at the worst possible time when I had my flight in the morning and had holidays planned. Can you imagine how this messed up my plans... escalating this with LG to take responsibility but so far I'm only spending the phone for repair to one of LG approved repair centres in UK. I live in UK and European models should be fixed in the country you are in if there is repair centre.

Hopefully yours won't bootloop but somehow I wish that yours bootloop sooner than later before you run out of warranty. Also don't forget to back up your data constantly since when the bootloop hits you it usually hits you when you are the least prepared and when you need the phone the most....

Yes, if you want something similar to LG G4 go for the Moto X Pure, better specs, same price range ($200+ on Best Buy for the 32GB version) fully unlockable and possible fast updates from Google.

LG G4 IMEI 606* just died

*** Of corse I meant S/N and not IMEI in post subject! ***
So, my new (bought end of May) LG G4 just died. No boot loop no nothing. It just won't turn on anymore.
Before dying it stopped charging at a random %, thought that was some random software issue, of course that wasn't.
Anyone else had same issue?

Hey there, 606 here too, bought at the same time. No issues whatsoever. Lets hope it it was just an isolate incident
BTW, did you try to take out the battery and put it back again?

It's not the beginning of your IMEI, that might be linked to device failures, it's your serial number. If your serial number would start with 606, your device would have been manufactured in June 2016.
Lookup your production date etc.: http://imeidata.net/warranty/lg?imei=<IMEI GOES HERE>

It would help to know when yours was actually made as buying a 606 (June 2016 manufacturered) phone in May 2016 = 605 means you bought a phone made in the future.

LG G4 bootloop problem

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.

yes they do but in a lower sacel. so its i would say if you get a 6XX 601 and up maybe a 30% chance.. just make sure it has warranty.

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
i had a 506 which bootlooped, now I have 609. I hope this one is not gonna

Bootloop fixed?

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

So, phones with serial starting 603 and higher doesn't have this problem?

After seeing it, should I ask him for a serial number photo?

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.
