LG G4 (H815) variant shuts off and doesnt respond........ Need photos recovered :(

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

I have been trying for past 3days removing the battery and charging for whole day, nothing helped till now

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.

LG G4 NOT stuck in bootloop but not booting past LG logo [goes off]

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

LG G4 weird bootloop

I was regularly using my G4, it was on cyanogenmod 13 nightlys for a good while now and i updated it every week or so. (haven't updated it in at least 10 days this time but it shouldn't be an issue) Suddenly the device turned itself off and went into a bootloop. I found a couple of weird things with this bootloop.
1. it wont boot into the device ever. it just shows the LG logo for a few seconds, goes black for a second then repeat.
2. I cant enter recovery mode, i used the button combination and go to the "factory reset" screen, selected 'yes' twice and i should have been sent to TWRP, which i have installed. But instead it just took a while on the yes/no screen and then blacked out, and rebooted back into the loop.
3. Sometimes it goes a bit further in the loop, and gets a little into the boot animation i have. I found that letting it run a longer time gets me a higher chance to see my little boot animation.
ive heard there was a hardware issue with LG G4's that were bought back in September of 2015 but i bought mine in June last year so i don't think that's the issue.
i didn't backup my phone for a long time so i'd love to get my files back! (otherwise I'm getting a new phone in a couple of days but i still need it until then)
Any and all help will be greatly appreciated! thanks!

What is your phone's S/N?
Sent from my LG-H815 using Tapatalk

I have the exact same problem, my phone died like this yesterday. The colder the phone is the longer it runs without rebooting so that might be a hint for you, although i have never seen it boot up completely. Maybe you can put it in the freezer or something like that. I was lucky because i just switched to cm13 and make backups of all my data the day before.

no idea. I know it hits some within a specific range but i did check the back of the phone where the battery is and it says there H815 0506 twice H815 0430 once and H815 0508 and H815 0501 both once. Does this mean anything? how can i check the S/N if its in a loop?

heard about that, i didnt try freezer because that sounds kinda stupid and i dont feel safe doing it but i put it in front of my A/C and it cooled down but i dont think it made any special change.

I'm sorry but it seems you both have THE bootloop problem not a weird bootloop.. It does affect many more than "bought in September" devices. Actually more of the June devices..
Sorry.

Damn that sucks! Any way confirmed to fix this issue? I dont think warranty will fix a boot loader unlocked phone.

People in the US and some European countries (ie Germany) didn't have a problem getting it fixed under warranty despite unlocked bootloader, root or even custom roms (because it's a known hardware issue unrelated to software).
Others did.
Try, you got nothing lose..
As for a fix, there is a process that involves disabling CPU cores, has worked for some. Check http://forum.xda-developers.com/showthread.php?p=67149552

I bought the phone as an international phone from a phone store. I dont have an LG center here and if i try to ask the store to fix it under warrently i'll probably get turned down because the bootloader is unlocked (you can clearly see that in the LG screen)
I will try talking to them but with ~20 days of warranty remaining i doubt my success chances are high

I brought mine from a phone store unlocked too (Carphone Warehouse in the UK) and it also had an unlocked bootloader running Cm13.
When it started suffering the bootloop problem they repaired it no questions asked. Worth a go.

Mine done that but wouldn't turn on after I took battery out I didn't try asking on here but no luck so I took it to insurance and I ended up with the g5 as they had no g4 repaired and ready to come back to me in 24 hours lol. Carphone warehouse ? big thanks to them now to wait for g5 to get some good stuff ... ?

is my LG G4 bricked? NOT bootloop, but some other issue [URGENT HELP NEEDED]

Hi folks,
I own a LG G4 AT&T version. Today, after charging to to 100%, I'd been using it normally, texting my friend. After taping the send button, I placed my G4 nearby and continued doing other stuff. & after sometime when I picked it up and double tapped the screen, it just didn't responded.
I pressed back button, I tried plugging charging cable to see whether LED is working or not, that was not working. I pushed out the battery and then put it back and tried turning on again and nothing happened at all. Its like still. Not responding at all. I tried the volume and power button combinations, tried hard reset, even tried connecting to PC and LG UP was unable to recognize, though it has all the necessary drivers installed.
I'm stuck badly, it was my daily driver, no warranty or official support in Pakistan, unfortunately.
is there any way at all to get it working or I should digest the bitter fact that its no more and move on?
Thanks.

Repaired n refurbished set Korean models only for 20k good condition factory stock cost aroud 24 international 25k ...take it technician see what he says

It does sound like a bootloop issue. Mine packed up last week and it is now on the way to LG repair centre here in UK. I was taking photos and put my phone into the pocket and when i took out I couldn't even turn it on. The phone was totally dead. However taking the battery out, putting it back in and trying to start the phone for numerous times it did eventually get into booting but of course it never goes past it due to motherboard failure. Try connecting to the charger and leave it for some time and maybe you'll get to boot screen but one thing for sure is that you can say all your data goodbye no matter how sad it is and LG bastards do not take any responsibility for it apart from replacing motherboard if it is within warranty.

LG G3 Bootloop in Download mode Stock ROM

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
