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...

my phone is rooted i'm on 13B everything was fine since i got my phone back in august till today i was listening music and was gonna skip to next song that moment is when my phone froze completely after pressing the power button the phone reboot by itself but got stuck on the lg screen i removed the battery after a few attempts it turned on. after 30 minutes or so it rebooted it self again but now even removing the battery it won't pass the lg screen. any ideas? suggestions?
probably the same problem a lot of other people are having. I also had the same symptoms as you, on rooted 13B.
you can try resetting or reflashing your phone but most likely you need a replacement.
theirs a problem with the motherboard going bad, i just had the same problem and lg sent me a replacement under warranty but i wasnt rooted

I put the phone in download mode and flashed 13B KDZ. But unfortunately my phone got back in the bootlop. Good thing I'm gettingmy replacement
It's a hardware issue, not software. A lot of the earlier G4s have "loose contacts" that cause the bootloop to occur. LG has acknolwedged it and are replacing any affected phones without incident. Just call verizon and they'll ship a new one.
Yup, happened to me just his week. VZW shipped another one to arrive the next day. FWIW, I strongly recommend everyone backup their phone to removable SD card using LG's on board Backup utility. If this challenge happens to you, getting back up and running quickly will be much easier if you have this backup ready to go.
...my $.02.
Happened to me as well last night. Took it back to Verizon today and they are sending me another one. I didn't have insurance and no questions were asked. Obviously they recognize the problem. Last LG phone I will own! Unless the G5 is insane. Hehe
Happened to me as well, yesterday. Interesting how this is happening to everyone at almost the same timeframe. I'll take it to Verizon to get a replacement shipped.
I had the same problem, and contacted LG support and they said it will take 9 business days to repair the phone. This seemed like an awful long time to be without a phone, I asked if there was any way to speed the process up and they said no. Thankfully I was able to borrow a phone from work for the duration of the repairs. Considering how this is a major problem with many handsets, I think LG is handling the whole situation pretty badly.
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.
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

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?

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?

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.

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 ... ?

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

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

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
