Hello guys,
I'm new here, nice to meet you!
For about 3 months i'm trying to fix my LG G3 D855 but with no success.
It started with a loud buzzing, screen freeze and the only way to power it off was to take off the battery. Since then it keeps freezing and i can't use the phone.
I tried the trick with a card placed under the chip, it worked, no restarts or freezes for about 3 weeks but after that i can't make it work. I also successfully flashed the D85530B_00_1217.kdz with the LgFlashTool but the problem it's still there. My phone has the stock rom and it's unrooted.
During this time i got a lot of blue/green/black/red/orange screens with QPST Configuration but i can't attached them because i'm new.
Do you have any idea what can i do to fix it or what caused the problem?
Thank you!
I have the same problem and I thought it's because phone gets hot but even when I was inside Cpu-Z it happened and it restart by itself then it stuck on LG Logo with some strange noise, I have to pull the battery out. Sometimes It turns on and works for a few hours .
I haven't been able to find the problem.
If you fixed your problem I appreciate write it here, how you fixed it.
There are no solutions other than the ones listed in the countless threads around the forum (there really is no need to create a new one every time).
You should use a thermal pad instead to help with the heat dissipation.
If that doesn't help only a proper repair technician with the correct equipment (very hard to find) can fix it.
You can as a last resort, try heating the entire motherboard. This is further damaging the phone though, so use it only as a last resort to get the data off the phone.

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

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

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

Hi,
My mother LG G4 just died last week. And it has a lot of important data.
What is the way to revive it. even if temporary. I just want to extract the data and take it to the store I bought it from (2 weeks until the end of warranty)
The problem is I can't make the phone to turn on. I saw some people having this issue reported that there phone just stuck in a bootloop. the problem with me is that I can't even reach that point. Black screen all the time.
I did froze the phone. and it works for less that 3 mins. didn't reach home screen.
I also tried the Big core disable method. the phone restarted before restarting command in LGUP. and still in bootloop with black screen.
Now I want to try heating the phone with hairdryer. hope it works for more than 1 hour
I encounter the same problem as you (see my post) do. Except LG UP is useless for me.
For what I've read here and there, the method with the hair dryer seems to be the better one. With this you should be able to boot him properly and save the data you want.
As far as I'm concerned I will try to get the phone back to my retailer even if the phone has an unlocked bootloader. Indeed, as the issue is hardware and not software...maybe...

I was rigth to get it back to my retailer as they fixed the phone. So I flashed it again and for the moment works like a charm (even though I notice like a screen remanence) !!
My LG G3 D855 was working fine... i left it for a while and when i came back to it it wouldn't turn on. I tried to take out the battery and put it back in ad it seemed to have worked but i got instantly a blue screen before the LG boot up animation or the LED color switching. I tried reinstalling stock firmware but i can't get it recognized by my PC. I have heard about baking the motherboard but i want to leave it as my last option since it may lead to permanent damage, my phone was a bit hot on touch when i grabbed it so i think some welds are damaged or something that has been caused due to heat. If anyone can help me i would be grateful because i can't afford another cell phone at the moment and i need one on daily basis.
Anyway thank you in advance for even trying to help me with my situation and i hope you are the person with the right answer
Kind regards,
Harisprodude
