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

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 !

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

Dear All,
A friend have LG G4 H818P the Dual SIM variant, While he was using Facebook the device suddenly turned off, tried to charge it with no hope, can't enter download mode or hard reset
He gave it to me for a try, i try the old thing with wrapping the phone in a piece of cloth and left it in freezer for 30 minutes - don't laugh - plugged the battery and the phone is working !!! started with LG logo with no successful boot to main screens just LG Logo.
Once the phone isn't a freeze cold it wouldn't turn on !! which is very strange , every time i leave it in freezer for 15 minutes or less it works !!
Will try now to enter the hard reset and do it, also downloading it's latest KDZ and will try to flash it but any idea what's happening and how can i solve it ??
Thank You

I have a h815 lg g4 32 gb. Running on MM. I had the same problem with my device today. I couldn't solve it. All i want is save my data. Windows os not recognized my device. QHSUSB_BLUNK. I guess it's brick. I don't know it's soft or hard brick. I guess i can save my data on linux os or fix the problem on it. Any idea?

seems like infamous bootloop.. if under warranty send it to LG but it must be to the corresponding country it belongs. like if am in america then i have h815 usa wont fix it i have to send it to europe.
or replace motherboard yourself
Unfortunately it's not under warranty, he had it for a year and 4 months
So no one was able to fix this at all ?? it's very annoying !

why not give it a try.. they might fix it.. as it is a hardware problem that many devices are suffering.
Same here
Ok so I have the lg g4 h811 2nd variant after getting the original replaced by lg because of infamous boot loop problem, get the one that was redesigned to negate that error. So this Phone dies while watching YouTube and tried freezing it, discharging the capacitor, new battery the whole 9 yards. No go. New problem maybe? Touched a multimeter to all possible problem areas and it looks like the whole thing shorted out from top of board to bottom all at once because it read max resistance. The whole thing is dead unless someone has an idea to revive it?
same problem
i have the same problem here
waiting for some help

Pop out battery
Take out screws
Don't bother with camera screws
Pry plastic
You will now see the motherboard
Get a blow dryer
Heat this part for 5 minute full blast
Do not touch actual chip.. But do get pretty close
Put cover and screws battery back in
Power up
If she bootloops again....heat it again
ops
My Lg G4 H811 unlocked went into bootloop after one year of usage, i tried hard reset but in vain, than i went for this method described on youtube https://www.youtube.com/watch?v=TM9umec5aeo (since comments were positive for this) involving keeping hot cloth iron/press over motherboard. But after this my phone is dead, I don't know whether the iron did something with motherboard
Now what are options with me, can replacing Just replace EMMC can recover or motherboard needs to be replaced?
Can H815 motheboard be installed on h811?

For the most part the mbs are interchangable. And u do have to replace whole mb. As the problem lies in the big cpus not emmc
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.
