[Q] Backlight dead?

Hi,
I just get a e-980.
With no special reason, the screen stop working, I realized under the sunlight, that my LCD still working, but I have no more backlight.
I can barely see white color shapes.
Is it a ''normal'' issue with those phones?
- I've opened it, clean contacts from ribbon cables. - didn't work
- I've done a complete stock reflash with LgFlashTool - didn't work
If you guys have no clue, I'm scared that I'm dealing with a brick, and get back my old reliable desireZ
thank you

Guess first thing to do in such a situation is to check if there is some obvious glitch- maybe brightness turned down to zero, phone not waking up die to some mod etc.. If does not work, then next is factory reset.. Next is a tot flash and then visit to the service center

yep. All done.
Like I said, I can receive calls/txt. I ear the unlock sound, etc. I can see LCD ON under bright sunlight.
Right now, I'm just thinking to throw it in the garbage, a 250$us phone that worked 2 days !!! Wow, people told me to never touch LG, I start to believe them.
Maybe some body here can sell me a functional LCD with broken digitizer??, mine is brand new.
I just dont want to dump more money in it, since the HTC is working strong, even for a 4 yo device
I'll try with LG warranty service, but it was a final sale

Exactly same issue with me too
I bought my LG OPTIMUS G PRO a few days back refurbished, it worked flawlessly for around a week. A few days ago its screen went blank even though it was possible to use screen blank like answering calls etc, i thought humidity has affected it and buried it in rice for one day and it worked again but after 2 days it again went blank and this time burying it didn't help. I am without luck now and looking for some workaround. Please someone help us if anyone knows how to fix it?
Awaiting eagerly for some suggestions.:crying:

Mmm seem to be a LG problem...
Event on optimus G forums people seems to have this trouble.
You just remind me something, went the screen go off, it was 90% rel humidity here, good point.
I tried to put it under high heat and the freezer. no luck.
All I want to know it's if it's the main board problem or screen.
Last time with LG pos, my brother had the LG 3D, wow, pos as well, nexus aren't the best phone as well.
HTC ftw, but the latest models are so no-user friendly on the hardware, seems like they try to copy apple.
My moto milestone 500mhz (2009) still working better than this, lol.

If you don't have a warranty, I'd open it up then clean and reseat the screen dongle connector.

This happened to my optimus g. Suddenly the screen went dark. I opened it up reseated everything and it didn't help. Thinking of buying a mee lcd when I find one cheap enough

yeah, but how you'll be sure that problem wont came back in a year?
The last time I heard about backlight stop working/burn, it was on compaq laptop with pentiumII processor.
1 1/2 year old phone, that's not normal.
any way, I put the phone in a bag of rice for the night, powered up, and the back light came on for 3 seconds.
-- 5 days and still have NO supports from LG.

This is just a thought. I had something similar happen in one of two ways, either the screen turning all red or dark. It was an issue with a night reading program, Twilight. After I managed to turn that off the problem went away.
If you have programs like Lux or Twilight running or anything that can control the screen try and turn them off.

Update.
I didn't touch the phone for days, leaving the battery out. Then I put it back just to be ready to retry a clean flash.
Screen all black.
I had something to do, I leave it on my desk for few hours, and when I came back to play with it, the screen light up. It's been a day , no issue, but some times the screen flicker.
It will probably let me down soon.
Strange issue : the home button led light doesn't work anymore.
Is it because I flashed the telcel stock rom on the e980 at&t?

DOES SOMEONE know HOW to get service FROM THIS company????

They just don't care, the moment I said that I bought this phone to the US and use it on a Canada carrier (Rogers / At&T , dont need to unlock the phone! ) , they flush me .
WTF???????????
Seriously people, don't deal with them.
So far, what I learn is that more this device is getting old ( wtf? a year or so isn't old) they have observed this issue.
Be careful pals, don't over use it

IF you buy a LG product, do not expect customer support. My e980 had a failed battery at 10months, LG basically told me to go screw my self. (Wanted me to pay to ship the phone, which would cost more then a new battery, and why do they need the phone when the battery is faulty, i gave up, bought myself a new battery, and have been good since. ) other then that, i like their hardware, ive had a G2X and now the G pro.

I see a lot of people try to blame manufacturer for the issues of their phone. LG, HTC, Samsung, Apple.
Remember, they all offer one year warranty. So if your phone is still under warranty, go RMA. I already got two HTC and one Samsung exchanged.
If your phone is not under warranty, did you buy it used ? Then you should blame the previous owner or yourself. Why did this happen to your phone ONLY while ten's of thousands of users here are fine?Did you do something that may cause the issue?
This is not personal. I just try to say something fair when I see people said "Never touch LG/Samsung/HTC.."
It won't help your phone come back. And it did mislead other users

It doesn't sound like they told you to "go screw yourself" exactly. It actually makes quite a bit of sense that a manufacturer would want all of a faulty device to arrive rather than that their customer just send them the parts they assessed as faulty. If they had to send you a new device, they would probably want the old one intact.

I called LG to exchange my Nexus 4 earlier this year. I call only once and they give me a shipping address( HTC also give address when I called ), asking to ship within 10 days or so .
They did NOT ask the carrier of my Nexus 4.( T-Mobile if you want to know ). They just check Imei and verified that the phone was under warranty.
I did not send the phone back to LG in the end. Someone bought it from me. The Nexus 4 has light yellow tint on display but hardly noticeable. The buyer don't care..
My point is, OP, I guess you did not told us that your phone might not be under warranty

Asking you to shipping back to factory is Exactly what is called customer service.
All manufacturers do so!
They need to run full software and hardware check on your device, making sure that all parts are working when they return the phone to you.
You might care a few bucks shipping cost . But truth is that maybe battery was not just the faulty part. Something else MIGHT go wrong as well. They need to find out once you call in for RMA.
It is YOU don't know what customer service is, Not them.

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.

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 understand exactly what you mean.

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!

Need help!! LG G4(H815) not starting

Hi all,
so here is my problem.
Day before yesterday i had a perfectly working LG g4 H815 model with s/n 511 running on firmware v20h, when i decided to root it and install some mods.
so i flashed TWRP, installed xposed and xtrememusic mod. the phone booted normally after installing these. i didn't install any modules under xposed. the phone worked perfectly for two days. however today morning it hanged while taking photo with the camera app. when restarting it got stuck at LG logo for long time. My brother(who doesn't have any technical knowledge) pulled out the battery and restarted. Again it got stuck at LG logo. thinking somthing wrong he again repeated this only to find that it didn't power on at all this time. No LG logo no notofication light nothing.
Tried charging it(although battery was aroung 60-70%), pressing power button removing the battery. still nothing. the phone is not at all powering up.
However when i connect it with USB cable with laptop, laptop makes sound of getting usb connection detected. i took it to a service centre.
the technical guy there told that IC may have been faulty. he told me that motherboard needs to be replaced. however unofficially he may try heating the IC to get it booting.
What should i do now? Is the IC really fried. had the rooting and installing mod caused it?
Please help.
PS- the phone is imported and cannot be sent back for warranty purpose.

I think you are experiencing the dreaded LG G4 bootloop. I don't think rooting or modding caused a software problem. It "may" have caused a hardware problem simply because it generated enough heat to loosen the IC that little bit that initiates the problems you are describing. I rooted and installed the stock image in Nov 2015. Two weeks ago the phone froze - restarted and then could not be booted. LG sent me a Fedex label and I sent it off. Ten days later I received the same phone back. I assume they replaced the mainboard.
You should contact LG directly. I saw a class action suit that was called off because it appeared that LG will fix this particular problem (failed mainboard) out of warranty. Anyone please correct me on this if I'm wrong.

Hi thanks for the help.
But isn't the dreaded bootloop is that where the phone is stuck at the LG logo. Mine isn't booting at all. And the bootloop problem is due to big cores or such and not due to ic?

Mine wouldn't start at all - it bootlooped once for about a split second - then it was dead

Same is the problem with me. Bootlooped twice and then its completely dead. I have tried contacting Lg UK. Lets see what they say.

Ok so i got a reply from LG and they suggested me some steps to take (which are obviously not useful as it is completely dead). however they have also told me that they are willing to help me and asked me about details of purchase etc and "whether it was rooted".
so what should i reply rooted or not? will they detect it as it is dead.

Sorry to be late on reply. I advise to not answer question whether phone was rooted. Here is my reasoning:
1. This problem is widely occuring - only a tiny percentage of people root their phones therefore question is irrelevant.
2. The problem is known to be that an IC becomes loose most likely due to heat - a better question would be - do you place the phone on a hot dashboard with GPS running while you are charging?

thanks for the reply (although late). i have already sent the phone to LG replying as no root. Lets hope they repair it without any problems.
second i didnt do anything of anysort like placing on hot dashboard or such. one day while opening the camera app it decided to just hang and later on die on me.

I hope you didn't think I was saying you might have done something that would overheat your phone such as my second example. I was trying to come up with an example reason the IC loosens. Even if you did that the phone should survive such conditions. Let's hope the replacement motherboards somehow do better. My guess is that the soldering job is fine, the problem is probably bad design that doesn't "vent" the heat from chip.

so what do you suggest after repair should i keep it or sell it? Lg g4 is no doubt the best phone when considering the value for money. no phone even twice in price comes close in camera and screen quality especially. but the unreliability of this phone has made me to consider selling it as soon as i get it back.

I'd keep it if your new board is high serial

Well my old board was also high serial, beginning with 511

I'm going to take my chances - it's a great phone until it bootloops. I'm going to avoid scenarios best I can that could result in the phone heating up inside. That would be charging only if absolutely necessary while in my ProClip dash mount if the car is hot, using backup battery after depletion instead of charging more often etc. Thinking back I rarely put the phone into heat inducing situations - normal use results in the IC becoming loose at the 1 year mark. If mine bootloops exactly a year from now and LG fixes it again I'm an LG fan. If they blow me off no more LG.
I really regret not paying it off early and taking the $15/month deal for an S7 Edge last month

I really regret not paying it off early and taking the $15/month deal for an S7 Edge last month

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.

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

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

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

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

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.
