Bootloop still a problem? - G4 Q&A, Help & Troubleshooting

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

I just got the bootloop today.
It was the european model, which should have been better.

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.

i also have 505 s/n production date of may it still works like it did first day usually bootloop occurs after 9 to 10 months its already been an year n one month:good::good::fingers-crossed::fingers-crossed: i have H815 taiwanese model had a chat with one of LG technician today he says he hasnt yet seen this country's models to bootloop as of yet seen eur,sea and other carrier variants ...

See u guys say the serial is in your case 505 as the first 3 digits Every num on my box here it goes. Upc 528. Dec starts 528. Hex 357. Iccid 890. Rs. 171. These are the first 3 digits in every number on my phone Again how do u. determine the serial num.

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.

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 not on a euro G4 BL unlock isn't possible to begin with.

Right, this is what i was hinting at. You have to be desperate to try something like this which could end up forfeiting everything.

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.
But the single sim thread it never 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.

Semi-Dead 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,

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.

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.

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.

will my g4 bootloop?

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.

Thanks so much for the response!!! So do you recommend I return the phone as there is a risk of boot loop and the phone is from Taiwan so they may not fix it?

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

Definitely the cause. I did always notice with stock ROMs Genisys etc my phone got hotter than CM and logically it makes sense so I'm sticking with it :fingers-crossed:

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 always better options than LG out there...the credibility rate for lg is always has been the worst thats why there used phones are sold dirt cheap everywhere
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

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>

I'm pretty sure my S/N is 606. I'll check when I get home, maybe I'm wrong
EDIT: Nevermind, it's 602

yeah, tried everything and with a different battery too.
Yes, I really hope that's just bad luck...

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.

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

Thanks for your reply:good:
So, phones with serial starting 603 and higher doesn't have this problem?
The one I'm planning to buy is this, I asked the seller to send me a screenshot of hardware info.
After seeing it, should I ask him for a serial number photo?

this is very interesting! How do you know that from SN 603 there are no more bootloops? Is there a statement from LG?

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.
