Ok' i got LG G4 H815
My dad were using this phone suddenly it just stopped working.
When he gave me the phone i tried to boot and it got into the part where it optimizing apps and it just froze and rebooted.
After that it stuck and black screen appears.
Until i pullout the battery and turn on the device it wont respond.
Now im on Download Mode, i dont know what to do. please help me
Send the phone to LG, they should replace the defective motherboard without any charges. Because it is a hardware failure responsible by LG. Only 2015's LG flagships LG G4 and the LG V10 are prone due to their early batches.

Hello guys,
I have a LG G4 H815 variant which shut off while talking on the phone. I did not install any new apps or anything new but got OTA update from LG 2-3 days before this happened.
I removed the battery and after I kept it back, and sometimes LG logo comes and then phone shuts off. Few times it also rebooted like 3-4 times by itself but did not pass the lg logo screen.
Now comes the most important thing, we recently had a baby (5days ago) and have all the photographs and videos of birth and delivery in this phone. I need that to be recovered, so please help with this first and then may be fix the phone next.
So hard reset of the phone is not an option I suppose. I also tried connecting to windows/Mac and system doesnt recognise the phone
I really appreciate any help from you guys.
sounds like you have the lg bootloop bug people have kept trying and eventually the phone has started

So do you mean to send it to UK..... I called US LG support, they said to contact UK support.... they said, they can only send packages to Uk to send the phone for repairs. What about the data on phone? I need the very important photos of my newborn.
try the freezer method

I brought the phone back to the shop where I bought it, as I had a 2 year warranty with them. They sent it to one of their repair centers and in 8 days it was fixed for free.
I suggest to try the freezer method posted above and hopefully it will boot and you can manage to get your photos off the phone.
In case it won't boot all or just sits on the LG logo, then it is hard to recover as (probably) they have to replace the whole motherboard (like in my case) and it is unlikely they will bother with recovering data. However you may ask them very nicely, but they might just ignore it.
I was using my phone as usual. Like hearing music. Suddenly bluescreen came.
Now phone is not booting. It shows blue screen.
And some time a green screen come where it shows this message :
GreenScreen Error Message

I think it is due to the marshmallow. ..my phone was working fine for 1 year until I decided to flash v30b and blue screen after a few weeks of v30b.
Now my phone cannot boot up, no download mode, no fast boot, no recovery

I used 6.0 for almost 3 months. and now, it cannot boot up too, it was just a blank blue screen. Not too sure if it is all about marshmallow, coz i found some users had encountered blue screen of death since lollipop year..

Maybe it related to the motherboard? I know about some lg g4 motherboard have bootloop error and lg is aware of that. ..maybe some motherboard of lg g3 is also faulty? Just that lg is not aware/choose not to care about lg g3 blue screen error

I think your right with the motherboard. Most people with this bluescreen of death didn't used the lg charger for charging the G3. Then the motherboard overheats and after more and more charges with the wrong charger it dies. Then only a change of the motherboard helps. I know a few people where LG changed the motherboard, but they still got there warranty. If you lost your warranty LG will say to you that its cheaper to buy a new phone, because a motherboard change is quite expensive.

Isn't any charger the same as lg g3 charger? I used to buy 3rd party charger to charge my s5/moto g and it works fine..
Unless lg g3 needs the orginal lg charger
i got the same problem... pretty much exactly the same time you got it... trying to figure out what the problem is. i was able to get into safe mode but now i cant seem to stay in it, it blue screens pretty much as soon as i get in
Any fix you found for this so far?
I've got the same problem. I never used another charger than the original.
I contacted LG and they just don't care. They said: buy another battery. I refused because I had given them a picture of the fault (green screen and also orange screen) My phone is out of guarantee (it's 28 months old). Now they let me know that they can't help me because it's out of guarantee. I found it very sad because I see many people have this problem. So they know this issue. Isn't it then a manufacturing defect?

Hi all, ok tonight/this morning at work while on my break i went to do my usual thing of having food and watching a tv show via cartoon hd about 2mins in and my phone switched off.....now i thought it was dead so plugged in the charger but no led light, or screen on to say its charging.....i did a bit of googling and find out about the bootloop thingy buuuuut mines not looping, its swtiching on to the LG logo [i did the bootloader unlocker thingy etc so it says tha in the top corner] then it goes off.......i also get pulsing blue led lights too.....if i press, hold the power button after i get nothing, i have to take the battery out and then its rinse and repeat
Hi,
Same thing happened to me today. I was taking a shot and it switched off and same scenario.It seems that we had encountered an bootloader brick in which our device enters in some special bootloader mode in which when you connect it to the computer in the device manager it shows up as Qhsusb_bulk. I read the whole internet and there is a similar brick with G3 the guys were able to fix it. Even there is a tutorial on how to do this which I think is applicable to our device. I was able to install the required drivers and etc. but there is one big problem - I followed the guide and came into one serious problem - we need a special mbn file so we can recover our device and the sad thing is nobody on the internet doesn't have it still. There are many people like us who got selfbricked G4 and cannot fix it without this file. Please if somebody can help us please share the file so we can fix our devices. THANK YOU !

ive seen lots about the bootloop issue, but the thing is mine isnt doing a loop [i have to take the battery out/ pop it it back in, to switch it on then after 10-20 seconds on the LOGO it turns off

on G2 you get security boot error phone is detected as QHUSb_BULK. on G2 the fix was to enter download mode. in G2 vol up then plug usb.
using TOT method and flash tools . flash stock firmware fixed my soft brick.
not sure about the file you mention, maybe you do need it..

I have the issue. I don't do anything special but my phone reboot and stuck on lg logo. But now my phone doesn't want to boot. Sometimes he detect when I'm trying to charge it but often not. Yesterday I boot on download mode and recovery but today it's impossible... I think I have some hardware issue ? Or software with the bootloader...
I don't know how to fix that without access to download/recovery mode :crying:
Same here. Sometimes it boots into recovery/download but most of the times it doesn't. It's a hardware problem I think as LG officially confirmed that there were problems during the building proccess of the first G4 series. I don't want to sound bad but soon or later all phones built before october last year will get into bootloop. I was hoping it won't happen to me - I'm very light user with only light standart apps with no games and other heavy stuff, so the problem wasn't caused by overheating by heavy multitasking. Anyway it happened and I'm pretty sure it's harware related but if somebody can provide the tot and mbn files I will be more than happy to try the g2/g3 unbrick method. The main problem is that these files are not available for h815. I found on other forum tot files for other variants than h815 So if somebody have the tot filesfor h815 please share so we can try to unbrick our G4. Thanks!
same thing heppened to my g4 this week. i called lg last night and they agreed to repair it. i'd just gave them a call.
I sent mine for repair today. I hope they will agree to repare it even that it's with unlocked bootloader and with rooted custom rom !!! What you think ? Will I have problems with them because of that ?
Happened with my phone as well. It was rooted so i was hella scared if they didn't accept my phone. But soon they told me phone's motherboard has gone bad and will be replaced. Got my phone with a brand new motherboard after a couple of hours.
P.s. all your data will be gone

So the same problem just happened to my lg H815 with unlocked bootloader, am really f***ed without my phone, gonna call LG UK tomorrow, anything in particular I should say? also looking for solutions I saw many people are starting to have this issue now too - any official comments from LG?
P.S. if you have an LG G4 you should start backing up all your data now
This literally just happened in the last 15 minutes to me as well. Random reboot right after I woke up the phone and now stuck on the LG splash screen. Light user here, never did anything with the phone that would have heavily stressed it physically or computing-wise, so I also concur it's an inevitability for earlier runs of G4 phones.
Luckily, I backed up everything through TWRP last Thursday by chance because I was updating Xposed to the latest version and swapping to a faster 128GB microSDXC. At worst, I might have lost a handful of unimportant text messages.
Not worth the time to try to figure out any cheap fixes myself, I just got done submitting a repair request to LG.
I ordered LG G4 H815 and I hope to not see any kind of these issues

Hi,
First of all, I had a bootloop problem couple of months back but it was fixed by a battery change. I had rooted my phone and then put the stock rom by using LG Flashtool. The Software now is Android 6.0 MM
Last week my phone randomly died on me while I was taking a picture. The battery percentage was 82 and yet it was bootlooping.
I got a new battery and the boot looping hasnt stopped. I tried to do LG Flash tool and LG UP and LG Suite but my phone turns off after a couple of seconds in download mode. I tried Factory reset by using the volume down button but it turns off when the android man appears. Now it even stopped showing percentage while I charge the phone.
I really think its software problem but I am not able to do anything to the damn thing. PLEASE HELP ME! :crying: I am running on a S2 and that thing is grandpa generation!
This maybe related to a hardware issue take it to a reputable technician u already said it was related to battery ... A swollen battery could have damaged ur g3 internals

Hello all members here,
My phone dead somehow that's I don't know, but it is dead and even give a a small lg logo. First time I see its logo and have some problem with charging ( bootloop of course ) than a few week later it is completely dead. I try to hot the motherboard using a hair dryer but no luck. Any help please!!!
If u aint rooted or modded. Its the classic hardware bootloop issue Or ilapo for short
Try seeing if lg will waranty it they extended the waranty dont know by how long but seems like theyre pretty lenient
