LG G4 H818P Bricked/Dead While using - G4 Q&A, Help & Troubleshooting

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

What happens when you do a factory reset? Does it load into CWM?
you can access download mode so you can unbrick your phone
I think its not a hardware problem because you can see the lg logo
If you can access cwm menu , wipe user data and cash , then flash hono stock ics.
Then if the phone startup was successful check the hardware parts via hidden menu in stock roms.

Hello,
Guys i did the whole unbricking guide but still when i restart the phone it goes into grey screen when the phone start up even after flashing the stock ICS and the Gb(No i was not able to gain access to CWM). The phone goes into grey screen and wont start up to set the account but if i revome the batter for a few min i can start it back up and go through the google account set up. But after a while if someone called me in the phone i cant hear what they are saying and they can hear me, if i restart is grey screen of death again. :crying::crying::crying::crying:
Thank you drumist for looking into this.
No i was not able to get into CWM. I have to do the unbricking guide to ICS was not able to go to GB as i cant root it goes into grey screen after the phone restarts while rooting causing the root to loose connection with the phone.
Please help.
I have the same problem. This is a problem in the system board. When pressed at a certain point the phone can turn on. I think the problem is contact a BGA chip

Yes this is the exactly the issue i am facing day by day it gets worst. The whole thing started after flashing CM10 ROM. the small bsod you get leads slowly into this. Guys i took real good care of my phone it never fell down from my hand nor does it have a scratch on it. never over did the flashing part as well, my advice is stick with the stock ICS. My Nitro is game over i bough a new Samsung s3. just a word of advice dont over do your beta flashing. :crying:

Please advice i tried every thing in the book and did not pull though.
You need to check the power IC, and make reballing
I was treated to the service (good repair workshop), they said that one of chips was soldered askew.
I think it one of this - Qualcomm PM8901, PM8058 and PM8?7? I do not know exactly.

you might want to retract this statement if this issue is caused by faulty soldering and not CM10

Dear Friend,
i believe i am still right the BSOD now a days Laptop are common mostly HP, its Due to the VGA chip being BGA(ball grid array) they are chips with small balls with soldering underneath them used for comm between the chip and the Bord. but went to chip overheats it melts the solder underneath and when it cools back down the solder get solid it a different area(we moving the phone like taking out of pocket or so) which causes lack of communication between chip and board(when they are back solid) it causes BSOD. I believe the Graphic chip in NITRO HD is using the BGA tech(It makes sense) so if our phone overheats too much the chances of De-aligning the solder in the chip is high cousin BSOD. We all know CM10 at the early stages caused overheating while in black screen coursing huge power drain in battery(we have stigmatic data with the help of battery analyst app).
So summer Nitro HD = BGA , CM10= overheating, Overheating=Bad for BGA(Causes BSOD) so overheating Nitro HD causes BSOD there u have it. i case if the phone really overheats while its in your pocket of in a uneven place and the solder goes out of place then you are in trouble like me.
Solution= Re balling or heat gun(temporary) Can FIX it.
So it's pm8028 near mdm9200
I got the same problem last weekend. I woke up and found the screen on and no sound from alarm clock. I checked and the phone got no sound at all.
I restarted the phone and got the gray screen. Late at the day the phone boot again but after another reboot it got the gray screen and never recovered.
I use CM10.1 and wind kernel with no overclock.
Too bad I didn't find any shop that reball the chips so my phone is dead
I got a i9305 today to replace it.
cn you fix the re-ball?

Can you enter recovery mode? If yes, do full wipe then flash your ROM.

Make sure the phone is fully charged before you try to boot it up, if it is fading out after the logo splash screen it either sounds like a dead battery or a badly flashed rom. You can enter into recovery by holding the volume down and pressing and holding the power button till you get prompted to wipe the phone.
I have had a couple of grey screens (or "black" screens) which I was able to recover from, simply by making sure the phone was powered off, then fully charging the battery for 4 hours, then booting into recovery and flashing a different ROM

ok... will attempt to reload
will try and download and attempt .....

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 !
Link to the g3 unbrick guide
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

My worst Nightmare ...Lg G4 DEAD ?

So its Saturday midnight and I m in my buddys house and we were talking and the same time i m on instagram and i scrall around ...when suddenly my G4 freezes and shuts down ...I say wtf and i just power it on (my battery was at around 42)...it starts to boot and suddenly begins to optimize apps ...okkkk i say let it finish ...when the optimization stops and its about to launch my homescreen suddenly blue screen and its powering off...I freaked out!!! i boot into recovery and wiped dalvik and cache...i reboot ....and starts again to optimize the apps ...i say ok everything is good then suddenly it dies again ....i say WTF !!! and i reboot into recovery to wipe everything and do a fresh intall of the Genisys 4.8 rom cause i did a dirty a couple days ago ...as soon as i wipe everything (i have sd and i keep everything there(roms gapps etc...))TWRP freezes and doens do anything after a while it dies again ...I reboot again into recovery to install the rom but when i swipe to flash it just freeze ..i retried it almost 10 times ...nothing it just not gonna do it ...as the time was passing i noticed that the duration between booting itno recovery and freezing was getting smaller and smaller ...so i left my buddys house to go home and flash the kdz (H81520i_00_0927) i put my phone into download mode i open lgup and i do the proper steps (choose the kdz ...closed the lgup ...and reopened it) so i start to refubrish my phone ...when the peosedure was about in 28-30 % my phone died ...I start cursing around ...i put it on the original charger to charge for an hour and a little more ...and i retry ...when the procedure was at 90%(when the phone starts to reboot) without any problems so far ...it starts to reboot but it never boot it just died again ...i pulled out the battery because it was the only way to make sure it was totally closed ...so i power it on and it passes the first lg logo power by android and the unlock bootloader stuff ..and it shows me the android robot with he's stomach working and suddenly it dies again....SO PLZ TELL ME WHATS WRONG WITH MY G4 ?
I want to add some information...
My model never had any bootloops
Its not from the production number with the famous problem
I have dig this particular problem to find if my device was one of them before i unlock the bootloader
For about 3 months i use to charge my g4 through a fast charge cable and though an OEM powerbank
Between a couple of reboots and throught the last time i tried to flash the KDZ my screen flicker the first time was random pixels and the last time it was horizontally the half ....
My first thought was that the battery died ...but when i saw the screen i wasn't sure...
The phone was bought 10 months ago normaly would have 2 months of warranty but with unlocked bootloader thats history ...
Dude, I believe you're having a battery or a hardware issue. Doesn't look like a bad rom installation or anything software related. I'd suggest you take it to LG Support.
Try to successfully pass the original KDZ prior going to LG Support...
i would say bootloop issue.
its the ILAPO issue bro. No more words.
Guys thank you so much for your replies ...I took it to a nearby tech shop that have services for smartphones and the found out that actually its a motherboard problem sometimes its working sometimes not ...we tried a new battery but it dint change anything ....Once again thank you for your replies

I think this is worse than the ILAPO.
I had the ILAPO and now i'm facing this same issue. The unique way to turn it on is putting it on the fridge 10 minutes but it takes 1 min to die again!

LG G4 is dead. Bootloop with Black screen

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...

LG G3 [D855] Blue Screen on boot up

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
