Need help!! LG G4(H815) not starting - G4 Q&A, Help & Troubleshooting

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

Marshmallow update caused bootloop

Hi all,
Just got news of the marshmallow being available to my LG G4 (H815). I was aware of the update having been rolled out to Poland and Korea before so I thought it was a safe bet.
I plugged in my phone, started the LG Bridge software which prompted me with the update. I went on and downloaded it, which happened without any issues.
However, when the process was over and my phone restarted, it went through the usual "app optimization" window and after that started boot-looping. I have the initial audio cue from LG playing every few minutes, with the same "app optimization" for 12 apps (when the first time it was around 90).
I initially left it for a while (5-10min) before i started losing patience. I removed the battery but that didn't change anything.
I initiated the Recovery mode, but it prompted me with a "factory reset" question, which I didn't feel like doing before having tried anything else.
My phone is not rooted and was running Android 5.1, the LG variant. I never fiddled with this phone.
Has anyone else experienced issues updating? Do you have any suggestions on what I can do to recover my data? Because for me, that's mostly what I'm concerned of.
Thanks!
Edit: In addition, I'm facing a new problem... while boot-looping, my phone is actually draining more energy from the battery than my charger can provide (yet, it's a 1,8A @ 5V).
It's now down to 10%, which I've been able to verify by removing the battery thus shutting down the phone, putting the battery back inside, and plugging the phone in while being off. However, this automatically turns on the phone, so it briefly displays the battery charging animation before booting... My phone was at 100% during the Marshmallow update.
Which S/N (serial number on your box) do you have? 505 and 506 are known for this issues..

yes it can be a issue of the 505.. Not to scare you or anybody else (there are people here that are crying and closing threads because i talk things like this.) But 505 is a known issue that some of the motherboards have defects. I hope you can fix it for yourself or call the cheap manufacturer LG..

Are you aware of this being a reason for replacement units to be issued? I didn't buy it through LG directly but through amazon, so I'll get in touch with them, but just wanted to know if you've had any experience or know of anything regarding this. And thanks for letting me know.

Np chief. They will fix your phone, just say it is in a bootloop after LG's official update. Call Amazon or LG itself to fixe this problem. (you mentioned you didnt root anything etc so you are good to go boss).

I figured, they would just try to restore my device and send it back to me, so I tried it and it worked. I'm still disapointed for two reasons:
- I still lost valuable data which I can't retrieve any more
- I'm still stuck with my device which could very well be prone to other issues in the future (any future update ?)
There are issues with this phone because i had 3 Rma's because of motherboard and dead pixels. My wife has also dead pixel and has version 506. Just use your phone, Marshmallow update is out so maybe they changed something in the system to stabilize the motherboard.

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?
Temp Fix
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.
Here's the link:

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.

Bootloop hardware failure and LG's incompetent repair

I finally ran into the bootloop problem that is common with early G4's (if you have a serial number that starts with 505, you're basically gonna be screwed at some point). Since it's a hardware issue that LG acknowledges, I sent it back to the factory under warranty, waited for two weeks using my old backup phone, and finally received it back today.
Ready for the fun part? They had repaired something that wasn't broken (kind of like surgery on the wrong body part) and had not touched the bootloop issue! They fixed "No power with cable" by replacing the flash memory. This was never an issue. The frustrating thing is that they didn't even restart the phone to find out if it had been fixed, because if they had it would have gone right back into the bootloop. Arg!
The G4 is now back on route to LG. I said they should give me a new phone, but customer service said they only do that if it cannot be repaired. I'll keep my fingers crossed that they go to the trouble to turn on the phone after "repair" this time.
Thanks for letting me rant!
I have currently my 2nd G4 that has run into this issue. This one has serial number starting with 506, so I guess it might stem a little further into production also. This is driving me nuts, I could not send my phone to LG because of how long it takes so had Verizon send me one and of course I run into the same exact issue with the bootloops. Last time I was able to still flash kdz's, this time won't even go past the LG boot screen. Really wish I could wipe my data at least.
I can attest to LG's incompetence. On March 2nd I sent in my G4 because it was bootlooping. Sent it in no problem, and after about a week I received my G4 back with the problem "fixed" by flashing the memory. Well guess what, it wasn't fixed. As soon as I turned it on, it started to bootloop again. I called LG and they arranged another RMA. Sent it back again, and about a week and a half later, I had my G4 back. This time they "fixed" it by replacing a capacitor. Guess what! Still not fixed. It still continued to bootloop. Called LG extremely angry and filed a complaint. LG arranged another RMA. At this point I had been without my phone for over 20 days. Finally, LG fixed it properly by replacing the motherboard. Now its fixed and it only took them over a month to figure it out.
While I applaud their easy RMA process, whoever the idiots are actually doing the repair are just that.. idiots. Its as if they don't even turn the phone on and ensure it fully boots up before they claim its fixed and ship it back. Whats worse for me is my phone was rooted on VS986B. Got the phone back on Marshmallow 24C and it took the update to 25a overnight. Now I'm stuck with no way of rooting.....
When you get your phone back from LG, chances are it will be on 24C. If you plan on rooting, do so quickly and downgrade.

No, that's the same. The board was replaced, but the plastic piece that holds that battery, which is on top of the board, was not replaced.
Happy to report that all is well after the second repair. Came back with 6.0, but I downgraded to 5.1, rooted, and have just about everything working again (can't get Exposed to work, but I'm sure I'll figure it out eventually). Nothing like spending 3+ weeks on a 2011 Droid Bionic to make me appreciate my G4!
Would one of you care to explain how you contacted LG to set up the repair. I have filled out the online form twice and have never heard a word. Thanks.

Im not sure if you are in the U.S., but here's their support phone number 800 243-0000. They are usually pretty easy to deal with over the phone.
I am still kicking myself that I didn't downgrade as soon as I got my phone back. I hate not having root anymore.

Droid bionic.. I wish! I originally dug up my old Galaxy Nexus, but the battery life was so bad that I swapped it out for my son's old Droid Razr. Of course, I had to safestrap it and put a custom ROM on there because I have a LG G Watch R and android wear was not compatible with the factory software on the Razr. It was a pretty horrible experience overall. I'm glad I have my G4 back, but I really miss root.
You can still downgrade to 5.1 and root. Mine was on the latest version when it came from the factory and I didn't have any problems with the process.
Same thing happened to me. It took 3 RMA's in a row and about 60 days until they finally fixed it. They scratched it, too. OP, I highly recommend you start documenting everything. LG CS will also tell you escalating will get you nowhere; but with persistence you can get a hold of someone. You can only go up to a supervisor, and that's it. LG has specifically designed their CS (including their facebook and twitter) to contain and ignore you.
In less than 1 calendar year i am on my 3rd phone.. Figuring the 1st phone was a flop... serial numbers since my 1st phone are 511 and 505. So yeah.. im debating at what a ticking timebomb i havenow. The 3rd one came w/ MM installed but I downgraded to LL to keep root. Im sure it goes w/o saying that I'll not buy an LG phone ever again.. and this was my 1st one. They could offer to upgrade me to a G5, but honestly there are NO guarantees this sort of thing will happen again. You break trust you pay the price, look at Samsung w/ the no MicroSD card fiasco.
LG just accepted my 15 month old G4 for warranty repair
Even though my phone is 15 months old, LG has accepted it under warranty repair. When requesting repair I wrote that it was the bootloop issue but their repair confirmation states the issue is "No Power with Cable". I hope they fix the correct issue! BTW, my serial number began with 511
The US warranty is 18 months, so LG didn't do you any favors. I have three of these POS phones to get warranty repaired and hope they fix them correctly the first time.

I just got mine back today june 1st 2017, Sent G4 for bootloops 1st time a week ago. No power / Mainboard was replaced. it was purchased november 2015 and Serial number is 511 which is right after the supposed bad batch. I got the phone back in the same great condition it left. The repair guy reported phone condition has minor scratches when it doesn't, Not sure why he would report that. So far its working great, like a new phone. I can only hope this board has been redesigned to not fail under a year and a half, but thats just wishful thinking. Everything was completely free even though phone was like 5months+ after its warranty. Even though costumer service on phone sounded like she was doped out on crack and ignoring all my questions, it was still ez to do and I got it back fast. The IEMI number or whatever was also changed and they put a new sticker over top the old one under the battery. I tried checking the number on that website and it doesn't even have it registered so i can only hope its brand new.
Got a couple of VS986s back from bootloop warranty repair. Mainboards supposedly repaired, but IMEI stayed the same and nothing on label under battery changed . I recall other people mentioned changes to label information.
Last week a representative told me the current warranty on the G4 for this issue is 27 months from date of manufacture or 24 months from date of purchase.
Mine has S/N 508. It started bootlooping while I was pooping (browsing Facebook on Chrome browser) on June 5.
I attempted the hot-air rework station fix 5 times (for processor on mainboard), and that worked on the 2nd, 3rd, and 4th tries. Each time the phone worked for up to ~4 hours. On the 5th try the phone no longer booted or even showed the LG logo.
It's en-route to LG right now. I opted to ship it without battery or back cover (my back cover has a wireless charging tag).
Using my old Samsung Galaxy S3 running an AOSP-variant on 4.4.2. Actually isn't a bad phone.
My old LG G2's touchscreen no longer responds to touches on roughly 50% of the screen... can't even unlock it via pattern lock any more.
Thinking LG won't be the next new phone I buy...
Well, my G4 is on its way back to me after LG's warranty repair. Turn-around time at the LG service facility was ONE (1) DAY!! So that was super fast. Should get it tomorrow or the day after. Contemplating putting it back up for sale or trade-in though... it's basically gonna be a virgin device that will require root, xposed, restoring apps/messages/call log/etc., then adjusting everything else to my liking. Would be a shame to do all that work and then the bootlooping problem happens again.

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!

Nexus 5x boot loop issues shoud i be worried that mine will do the same ?

Hello guys i've been seeing a lot of boot loop news and lg starting to refund people because they don't have spare parts : http://www.mobilechoiceuk.com/News/...offering-refunds-instead-of-replacements.aspx .
So should I be worried that my 5x will boot loop ? I've been using it for 2 months now on 7.0 september update .
just yesterday happened to mine!
Did you try to fix it or got it refunded under warranty ? Also rooted or stock with update ?
Hi, i guess that nobody could know that, but the problem seems to be the same as LG G4, LG V10, LG Flex 2 (all 2015 devices with almost the same motherboard that the Nexus 5x). You can search on the web "bootloop G4 reddit" "nexus 5x bootloop reddit" and you will find tons of reports, the majority of them (N5x) from last 3 months, and this holds the theory that is a welding issue on the CPU or sometimes on the EMMC chip (apparently LG did not weld very well that year...). The mentioned devices (included ours) seem to last from 9 to 14 months and finally the welding breaks. But now, we know it's strictly a HARDWARE issue NOT caused by 7.0 upgrade, irt's only a question of coincidence between the useful life of the weld and the launch of the 7.0 OTA.
So we all got very high possibilities that this occurs to our devices, eventually. I'm not sure that this is gonna happen to you, it really dependes of many many many factors (heavy usage, kernel profiles, temperature of your country/city/house/workplace, etc etc).
Maybe it never happens to you, but i know what you feel, is not very nice to feel that your phone could die in any moment. It was a low punch for me (i owned a G4 and it bootlooped twice) anyway i am going to sell my N5x due to this problem. Hope i help you with my point of view.
It is solder not weld.
Only Google/LG know how widespread the problem is on 5x.
My guess is it is far more than normally expected for phones but nowhere near as prevalent as posts on forums might make it seem.
So normally you might expect .01% of these types of solder problems. If the problem went up 100x to 1% and you sold 3m phones, that means 30,000 phones with the problem, whereas before you might only see 300.
30,000 people searching google and seeing other people posting about bootloop can start a panic.
If you actually had 10, 20, 30% of people with this problem you would have huge threads.
That's just my opinion.

If you said "It is solder not weld." for me, thanks i didn't know the correct word, english is not my native language (I only learn reading on forums), so i see that you know (or it seems) about solder problems. Look i had two LG G4 both of them die, but not just mine even a cousin had the same issue whit his G4, so i really want to know if you think that the 5x soldering problem is a similar case of high-end 2015 LG Phones G4/V10/FLEX2 (of that magnitude)? or if it's just a "paranoia", i mean we know that the bootlooping issue on this device exists but you would recommend me (i really like this phone) to keep it?
This issue got me really worried due to my bad experiencie with the G4. I just bought the N5x 1 month ago. thank you.
same question how to know if my phone will bootloop...i have my nexus 5x 5 week ago but i bay it not new i bay it used...i upgrade to android nougat no issus right now..ho to know if i will have a probleme in the future iam afraid now

I've been dealing with substandard solder since xbox RROD (red ring of death) where everyone was trying to get their xbox cpu reballed until microsoft admitted the problem.
As I mentioned, I'm sure the incident on 5x is much higher than normal phones, but that might still be a low % (even though it is a relatively high absolute # because of the # of phones that are sold)
I have no idea whether 5x is worse, better, or same as G4 problem. G4 seemed even higher, but could be because more phones were sold. Only LG knows for sure.
A lot of folks in US are finding that their credit card actually extends their warranty beyond manufacturers warranty and people will probably get their money back that way if all else fails.
Of course that doesn't help you if you are traveling and the phone dies. I end up using Google Fi as the service provider for this phone, so if that happened I could just shift all the calls and texts to another phone or tablet and keep going until I get a replacement phone, so I'm not super worried.
I regularly back up the stuff on my phone so the most I would lose is like 1 or 2 days of stuff, which I can deal with.
Personally I wouldn't be super worried this is going to happen to you, but be prepared with backups in case it does, but that is good practice for any phone, because it could always get stolen or drop and break.

Well from what I know if you don't have warranty paper then you can't get warranty by just showing the phone . Its not a 100% chance that it will boot loop I think , but if your not safe with it I suggest selling it working rather than looking for help when broken . Thats just my point of view .

Well I think i have the same point of view to sell the phone working rather that having a paper holder . At least for me its the most logical thing to do maybe the chance isn't high for it to happen but I am not secure with a tought that my phone could die + im a heavy user so i migh make it to the boot loop faster .

Well I don't know if there is or not but from what I know about the problem its random af , so I don't think there is unless only some motherboards are prone to the defect but I think it involves all , just happens randomly . Not 100% sure tho !
