Develop Bugs

DEAD

Once upon a time,about 8 months ago,there was the little newbie me,I that old E975(lgg) and decided he should get a new phone with all those "G4's" "S6's" etc,I wanted a phone with killer specs,and the best camera out there,so I decided to go with the g4,looked up prices online on his country. Pretty damn high,so i found that one shop that sold it for like 100$ less,no official warranty,unofficial warranty for 1 year,that seems fair,I bought it,the biggest mistake i ever made, the phone was so good,it worked like a charm,and god damn that camera was awesome,about 4 months ago i was sending a whatsapp when it just got stuck on that screen,m'kay i tried restarting,won't work,removed the battery and inserted an other one,boot to lg logo and then shut down,alright, i still got warranty. time to use it,went to the store,they said "we can't fix it",worst customer support EVER,ever since that I've been using that ****ty replacement phone,ewo,so today i was really bored and decided to look up the problem and noticed my s/n begins with "505" looked it up,apparently all the g4's with that s/n got stuck eventually,and the store knows that and since my warranty is unofficial I can't do ****,or can I? is there any way to get out of this with a functioning phone?help?

Mine died yesterday. It's a hardware fault apparently and can't be fixed. You can, however, disable big cores and recover your data, but your phone will be really slow.

i was just about to cook the phone and teared it apart,i saw the whole oven thing and i thought to myself "Why the hell not" and well it should work...if it will stay the same i'll use your tutorial and probably use the really slow G4 instead of my current 2012 Huawei

Phone doesn't work really slow, if you know what to do. My phone is working since I disabled the big cores what is about 2 weeks now, I'm even on a custom ROM. All you need to do is to root it and using 'Device Control Manager' (Kernel Adiutor doesn't work for me) change the frequency what will enable all 4 cores and with 4 there is no big difference in the performance really. I feel like it's more Qualcomms fail than LG's, cuz look G4 was first phone with Snapdragon 808 wasn't it? What if the first processors they made they sent to LG as they are all now in s/n's 505-509 and what if these are faulty? It actually would make sense, with 6 cores my phone didn't even turn on, with 4 it works as normal, it means there is 'something' wrong with the two faster cores..

It's LG's fault. They have admitted such. It's a faulty connection/motherboard.

UPDATE
i've baked the phone,it works for now,how can i make sure that it'll keep working?

Replace the motherboard.

but they don't sell them on my country,and it'll cost like 400$ with shipping,and nobody replaces mobo's here,so is there any way to make this one keep working?

I'm sorry, but unfortunately you dug your own grave with that one. You may have saved yourself $100, but caused yourself major issues in the long run sacrificing that warranty.

Honestly, there is apparently no way to ensure it'll keep working. A lot of users have reported their phone dying again after LG has fixed it. A motherboard replacement is the second best option with the first being a phone other than the G4.

Stay on G4 or move to OnePlus 3?

Guys, how do you think?
I have my G4 (S/N 512), camera is perfect, CPU is good, screen is excellent.
I don't care about updates, but I love Cyanogenmod, clean Android etc. I want to mod my phone, personalize it in every way I can. Unfortunelly I can't with locked bootloader. I could just unlock it, but I'm aware of bootloop. When it'll happen my phone will be just paper clip. So I'm thinking. The OP3 is near. OnePlus got great terms of guarantee. But still, I'm kinda in love with G4. I jumped from SGS3 to it. So it was my designed phone.
Anyway, what do you think? Will my phone brick? Move to OP3?

Stay until you get the bootloop (as you expect). It is kinda risk now to jump over to OP3. I know the rumoured specs are good but you wont loose by waiting a bit for some few reviews

lol op?Support epic joke.

Which serial number is your phone? I have a 510 device and i believe those are safe from the bootloop issue because those have the v1.1 motherboard. I unlocked the bootloader on mine because of this and it has been quite nice with CyanogenMod 13. However, like yourself i'm debating whether to upgrade the phone later this year. I don't 'hate' the G4, in fact it's a nice phone with a fantastic camera, screen and good performance. But there's something about it that i don't like, i bet this sounds stupid but it's just such a boring phone, honestly. Before this i had the OnePlus One and that felt like something genuinely special, and i kinda wish i'd stuck with that instead of buying the G4.
I doubt i'll go back to another OnePlus device because of their shocking customer service, if you end up with a bad device then it seems like you're gonna be ****ed for a few months. There was one person on Reddit who sent his phone back in February and still hasn't received it as of yesterday, like what the hell is that about. I'm going to wait and see what the new Nexus devices are like in about three months, i think that's the way forward for me because it would be nice to have a device which receives updates quicker than anything else, and always stays on top with the vast developmental community behind it. Only problem with those is the price and lack of a memory card slot, but we'll have to see what happens, maybe the prices will be a little more affordable this time to compete with the OP3 and similar devices.

What about Moto Z Force, if it's not only for US market? Depends on the price of course.

I just upgraded from my G3 to a factory refurb G4 and so far I really like it all except for the issue where you cannot wake up the phone by double tapping the screen like 99% of the time. There's supposed to be a way to upgrade the lg keyboard app unless you are, like myself, on Verizon in which case they so graciously removed all the useful settings menu items such as app upgrades, etc...

i have 601 how do i know what MB version i have?

If you want to hear my opinion for new phones:
Wait 1/2 to 1 year. Why?
• You know, if the phone will get its love by devs.
• It's also much cheaper.
• Many little hardware-bugs will probably be fixed.
3 good reasons to wait. New != better. Sad new world, I know. Except it's a Nexus: Same price until new one is released, same hardware - but devs will love it .

There should be a sticker on the inside of the box which states the serial number and has the motherboard version at the end in closed brackets. But as your phone is 601, it will have the updated motherboard and so you're safe from the bootloop problems.

thanks ill check it out.. but theres still people reporting bootloops even with 603. ??
i have it bootloader locked just in case. i own tmobile h811..

I think I am *very* close to going with the OnePlus 3. Just need a little more review/confirmation to make the jump.

Considering OP3 already has a CM13 build going and kernel sources out, I'd honestly get rid of the G4 while its still worth something. I would've done the same thing if it weren't for the fact my piece of garbage G4 decided to bootloop literally days before the OP3 release.

My double tap to wake used to work great. Then I got bootloop issue, had phone repaired from LG, and double tap to wake basically NEVER works. Not sure if it'd be worth a FDR or what.

Mine bootlooped friday and I'm going to get the OP3 in the next few days. I'm trying to get my G4 repaired, if LG dont do it then I'll use my insurance to have it replaced. I plan on using the time I have without it to see how I lkthe OP3. If I like it, I'll sell the G4, if not, I'll sell the OP3.
I've read a lot of bad things about OP3's support, but in trying to get my G4 repaired, it can't be much worse than LG's (edit: since I made this comment, I've been on LG Chat on their website with a really helpful guy called Carl who's said my phone is covered with a 2 year warranty and they will fix it - much better than the cookie cutter email response team).

No removable battery on the OP3. They claim to charge their phone to 100% in 45 minutes. The G4 can be at 100% in about 3 minutes from shutoff to reboot with a fresh battery installed. I love my G4.

I loved my G4 till it stopped working and LG refuse to fix it because rooting voids the warranty.

This statement is false and very dangerous for users. All smartphones, even with S/N starting with 60x are prone to bootloop problem. I have my LG G4 with v1.1 motherboard, S/N 602 and guess what happened to it...

Well, that's news to me. When i bought my G4 in December the bootloop problem had already become widely known, and i did extensive research into it on XDA and other websites, but at the time all 510 and 511 devices were deemed to be completely safe. If those devices were affected by the bootloop problem then i wouldn't have even considered buying it.

LOL, there are even cases of the new G5 bootlooping. LG has become such a joke. And it's a shame because the G4 would've been a perfect phone if they had caught the bootlooping and image retention issues while testing it.

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.

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

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 a phone that's never bootlooped

Screen ghosting LG G4

Hey guys,
Yesterday I noticed some screen ghosting on my LG g4 on the top right where the battery icon, signal status etc are. I turned it off for 6 hours and noticed it got slightly better then i used an app which stimulates all the pixels on the screen for about 8 hours by flashing different colours. After this all ghosting went away but after i used my phone for about 2 minutes it made a new ghost. Please help me fix this permanently. I am currently using the same app with the intention of keeping it on for a full day.

It can't be fixed. However you could replace screen.

Honestly LG has given me the worst android experience to date. Had the damn phone for 3 months an it was the taiwanese g4 which has no way to unlock its bootloader. The worst part is that the screen ghosting came up on the same day i decided to sell it and buy a oneplus 3 instead. Now i wont be able to sell it for a good price and that means i can't afford the oneplus. Never buying from LG again.

i have it also and it's ANNOYING as hell!!! I returned mine 2 weeks ago not only because of this but also because i cannot see nor connect to a 5 GHz Wi-Fi network.
Just 2 months prior top this the phone killed itself (not even 1 year old) and had to get a new PCB. LG if you are reading this, i want my money back.
Note to the people, please don't buy LG crap!

LG G4 bootloop
The bootloop - problem on all the LG phones from the main series is caused due to a less safety check in fabric and causes cause the processor releases from the mainboard during heat, mechanical load etc and the connections were broken! To fix, the processor have to pushed back on the mainboard with heat - I think a hair dryer is a good way to do that
If there are any other problems with the CPU itself - I don't know but sometimes the processor itself can be partially damaged
I've even a G4 which has stoped working on June.04.'17 and I'll try to apply this step in a professional environment. (you've to fully open it, put a hair dryer on the processor, heat the processor and push it down on the mainboard) The best video on yt to do that: search for "LG G4 BOOTLOOP FIX REPAIR VIDEO"
>>By holding the vol+ -key and plug in the USB-cable it bootet once... ..and works... ..but then heats up! - That might work for quick saving data on the PC!<<
I hope that could help!

Wanting to Upgrade from a G3

Hey guys,
I'm looking to upgrade from a G3, the only problem I am unsure of is the obvious bootloop problem. Is anyone still using G4's that have been working for a long time? I won't be gaming at all, the most intensive cpu task I will be doing is probably skype video calls. I really want a G4, but the bootloop problem seems like a real let down.
I was wondering if there are any G4 xda members who have followed the whole development of the bootloop problem on the forums, reddit, and everything else. I have looked at lots of stuff, but I don't really understand the progression of the issue as well as if I was watching it unfold. If someone has followed it, they probably have a better idea than I do, of the overall current situation on the bootloop issue.
I want to get a G4 because the newer phones like the G5 are starting to look pretty gross and they keep getting bigger and uglier. The G4 seems like the last good step at the moment from my trusty G3.
Cheers

1. Buy a model which can be unlocked (like the h815 international)
2. Ensure that the serial starts with 603 or higher (604,605...) best is to ensure it was not refurbished (e.g. motherboard replaced)
3. Ensure you will have warranty for at least 1 year
4. Do a regular backup once you've received your device
I own 2 models with serial 60x since 1 year without any single problem and heavy usage.
I saw no single prove(!) that a non refurbished 60x serial device has got that infamous bootloop yet.
Guarantees.. you will get none. For absolute no device. That's why a valid warranty is important.

3. Ensure you will have warranty for at least 1 year
4. Do a regular backup once you've received your device
I own 2 models with serial 60x since 1 year without any single problem and heavy usage.
I saw no single prove(!) that a non refurbished 60x serial device has got that infamous bootloop yet.
Guarantees.. you will get none. For absolute no device. That's why a valid warranty is important.

I see. So there haven't been any boot loop reports with 60x model numbers? I thought I read somewhere that LG hadn't fixed the problem at all?
I am planning to get the international version. However I don't know about the warranty, it seems like a waste of time. If my G4 ended up bootlooping I don't really think LG can truly fix the problem under warranty anyway. Either I get a 60x G4 without a warranty and it doesn't bootloop, or I get one and it does bootloop and if I also had a warranty it would be useless since that would mean that LG hasn't actually fixed the problem at all, and is unable to. It probably also means that at this late point with the G4 being an older device, they wont be trying to fix the G4 bootloop issue either.
I just want some more people who have G4s with later model numbers to give me some faith in buying one.

I know that fixed phones by lg with warranty still having that problem. But i dont know anything about 60x series

Hey guys,
I'm looking to upgrade from a G3, the only problem I am unsure of is the obvious bootloop problem. Is anyone still using G4's that have been working for a long time? I won't be gaming at all, the most intensive cpu task I will be doing is probably skype video calls. I really want a G4, but the bootloop problem seems like a real let down.
I was wondering if there are any G4 xda members who have followed the whole development of the bootloop problem on the forums, reddit, and everything else. I have looked at lots of stuff, but I don't really understand the progression of the issue as well as if I was watching it unfold. If someone has followed it, they probably have a better idea than I do, of the overall current situation on the bootloop issue.
I want to get a G4 because the newer phones like the G5 are starting to look pretty gross and they keep getting bigger and uglier. The G4 seems like the last good step at the moment from my trusty G3.
Cheers

first i would either keep the g3 or find something else.
i havnt had a bootloop issue yet but locked bl and just the scare of knowing my device is unusable any day. puts me on edge
now i know some people arent as ocd or anal as I. but if u are any where near what i am you dont need the stress in your life. lol
its a great device i do have root just no twrp and it has lots of potential even like it is on stock rom.
im glad i got it but ive sold it 3 times now and have ended up with it back in decent shape so its most def a soldier
i dont and have never had a waranty i did a thermal paste cooling mod on mine and for all i know that paste is whats kept the solder joint from breaking.
never did actually figure out how to tel what serial num mine has but its not a refurb and it was manfacrd in 10 of 2015
some of the g4s have a flashable tot file to "fix the issue" by shutting down the damaged cores but essentially turning it into a mid ranged quad core phone which i have shut mine down and have tested iffrent lowered clock speeds and still ok. not blazing fast but works.

You could also just wait some days for the g6

if you in USA get h811 and check the list of h815 that can be unlocked if you not in usa.
6xx have bootloops i have heard of 1-2 603's so the chances are very low compared to the first one.
i have been checking the thread here and only a few 6xx

Yeah I did read something about that core shutting down fix. So you have had yours for a year? I don't know how widespread the problem is, because most people won't go to the forums to praise a working phone. I really want to get one. But only if I can be reasonably comfortable that I am able to mod it or something to prevent a bootloop occuring. What is your use like? Do you game? I don't. It will be used lightly compared to most. I never install games.

I'm not in the US so I would get a H815. So do you think the reason for less bootloops being reported is due to people not buying the device anymore? Less people have that model? Or less of the people who would come onto the internet and complain? Less of the phone geeks ended up buying later G4s because of the bootloop reports?

i use it like a high end phone should. im not a super big gamer got the ps4 for that i d.id a writeup a while back on coverting samsung gear vr for g4 and ive done my share of vring. i use a otg cable and or blueputdroid to connect ps3 control to it for vr.
like i said i got a sprint varient which is on older firmware rooted no twrp very few modified stock roms.
i like the phone enough i busted two screens the orig and a aftermarket. btw dont ever buy from fixez.com claim oe quality its just a sheet of reg glass broke 2 weeks after i bought it 6 months ago from a scratch no bull**** no drop i ended up putting the spidered glass back on it.
the way ive eased my mind is basicly i buy sell and trade phones all the time. i have a backup i keep put up just incase.
also like i said i did do a thermal paste mod that helps cool her down.
ive sold my g3 3 times and ended up buying it back cause the people loved it so much theyve all upgraded to g5.
when and if i could i would prob buy a g5 or g6 when it comes out against my better judgment of lgs part
the selling point of a g4 is the camera manual mode takes some of the best night shots ive ever seen. days shots are killer

Ive not had it bootloop. Ive had it since. Jan of 2016. So ive passed the usuall 6 month bootloop period. Like i said dont know the serial. Never got a straight answer mine starts with like a 031. Or somthing. Only 50 or 60 num i got is a 508 and its in the middle of my serial. Like i said. 10 of 2015 is man date and a hardware rev of 1.1

So the hardware revision seems to have fixed it? I thought I read somewhere that it didn't fix it? Did LG at least make it less common?
Do you also know if this was happening to people across the board? Or was it just a few people? It's a bit risky I must say. How do you find the serial number?

i personly feal the thermal paste helped may not have.
but heat is the underlying issue of the ilapo bootloop the shear heat from the cores break a cold solder joint on 2 of the cores. i thermal pasted everything i could inside ill post a link to a write up i did.

people say the serial num is on the box but like i said never actually found it. they said hardware rev 1.1 was suposedly good which is stamped on the side of the box not on a sticker but printed
its all across the board all carriers.
thats what i was sayin killer phone but there is risk in it i gave up a non rootable note 5 note 4 and a rooted s6 and seem to take the g4 over all due to the features of ir blaster fully funtional . camera and knock on features

Thats really interesting. Have you heard of anyone else warding off the bootloops with thermal paste? It seems like quite a good thing to do. It would also be good on the G3. Thing is, if I get a G4 with a warranty. I wont be able to do that. Probably best to get a second hand one and do it.
Has anyone permanently fixed their phones by resolering the chip do you know?
Thanks for all the information mate

I dont know. I know people heat em with heat guns freeze em. Put paper in behind the chips to apply pressure. I thjnk im lone wolf on this therory

G3 is not a bad phone and G4 is not a big upgrade so I am not sure why would you want to upgrade. I'm sure there are better phones out there especially with 820 SoC released 808 is getting old. I bought my G4 1 year ago mainly because it was very cheap compared to similar models from other brands but now I don't see anything why would you buy it.

That's true. The only problem is, I am not in it for the specs really I am more into it for the looks/feel in the hand and possible continued support on XDA for the device. The G3 does still have it yes, but I would like to slowly work my way up. What would you be recommending? I was actually looking at downgrading to a Moto X 2013 edition because it feels just so damn good in the hand. The G5 and G6 look vomit worthy to me. I just hate the look of all the new flag ships coming out.
