Hello guys!
It all started today in the morning when I opened Instagram application on my G4 (H815 model) and suddenly the phone froze. After 15 or 20 seconds it tried to reboot itself but it went straight into bootloop. It's not acctually a bootloop. It tries to go past loading screen and reboots another time and after that all I can see is LG logo.
I tried to enter recovery mode. No success. I tried updating/flashing KDZ file with LG Flash Tool and I got error everytime saying there was not enough information....
Last thing I tried was to boot into download mode. It shows Firmware Update screen but I don't thing ADB is working. I tried command adb devices and it found nothing.
I'm so desperate now as I need phone tomorrow. I hope it's not hard-bricked. Do any of you have idea what to do?
Any help apprechiated
TIA

are you sure it's dead???
Cause, OMG!
I can't be without phone. Is there any other way?
And BTW, I have unlocked bootloader, so no warranty for me
Why do I need first 3 digits of serial number?

lots of people report bottloops theres a thread and i said about 80% suffers from it.. its a hardware problem from lg .
thers the flash kdz to disable big core ,phone will be slow but usable.. and some have reported that warranty was denied and some had luck and phone was fixed give it a try..
because the first phone are suppose to be more likely to suffer from it.. so to know if its old earlier phone. or new one . that soeant suppose to happen anymore but it still does..

Thanks for the info. I checked serial number on the box and it says 507. I know a lot of 505 has this issue.
Do you have a link to that thread to disable main cores? I can still sell working phone rather than bricked
And I'm so pissed now because I didn't do anything wrong. Damn LG! Life's not good anymore!!
Is there possibility to flash KDZ with other program than LG flash tool? I can't get it working, it always says it couldn't find right information...

I want to fix it. This would probably be possible if LG flash tool worked. Do you have any suggestions? I really like this phone

well, i guess I'll have to buy new phone. I'm a little disappointed with LG for this issue. Anyway, thanks for all of the useful posts. Thread can be locked now
Yes it's LG issue, but if you had not unlocked the bootloader , you would still have warranty. They will be fix this without problem

well only time will tell most will do .its just a matter of time.. since they are new and the ones getting bootloops are older.. so they say it takes about 8-9 months to show.. will need to wait and see. in 10 months from manufacturing date.
you cant tell wich one will but, LG says they fixed the issue in new phones..

Have you tried flash your KDZ file with LGUP software? http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803

Yes, I tried everything. I've sent LG G4 for repair with unlocked bootloader, they replaced it without problems. I was without phone for 16 days though. It's working now, but I have some WiFi issues (slow download speeds)

you could do 2 things.. one download KDZ use LGUP flash it and see if it was software related or something went wrong at flash.. if it keeps doing it then it has the bootloop issue.. and need to be sent back for repair....can you provide your first 3 digits of your serial number...?

yes it is its pretty easy... . file is big though... download kdz for you variant.. what android you are using.? MM or were you on stock LP.?
well i think since your phone is from 2015 august. that bootloop was supposed to be fixed by then. but newer phone are still getting hit by the bootloop.. but be aware unlocking the bootloader voids warranty.. some been lucky that phone were repaired some were denied repair..

Its been unlocked for ages and running the cyanogen rom, this is what is now stuck but was running fine. lg website doesnt have the programme any more, will hunt for it. so this will work even though phone doesnt boot?

here are the links but i think you got the BOOTLOOP problem that many been affected..
NO ...... the only way for your phone to boot and gather all data is to flash a moddedKDZ.. but am not sure if it works on your variant..
if you have warranty send it back...but if they find out its unlocked they may deny repair.. you must pay for it...
this will make it boot but it will make it slow. as it disables the main cores...

Going to give this a whirl now mate, thanks.
hello everybody
recently my H818p G4 , just got in a bootloop out of the blue , I tried all these safe mode , hard reset , .. nth works always freezes at one moment so I decided to reflash a KDZ
the thing is , the phone sometimes gets in download mode and sometimes it doesn't just like there is no battery inserted won't even boot with battery in and fully charged
the times when it gets into download mode it starts flashing and then it just reboot and stuck in LG logo in the middle of flashing process.
I used both LG flashtool and LGup softwares .. and same problem every single time
any fixes to this ?
Your phone has developed bootloop issue just like hundreds of us here (thus there is no need for another thread) so you have 2 options though ultimately it will be still repair job for LG if it is under warranty:
1) Temporary solution to disable big cores and try to recover the data if it is of any importance and you can have phone working for some time but it will be slow:
http://forum.xda-developers.com/showpost.php?p=67550617&postcount=1273
2) RMA your device to LG to have motherboard replaced

but the link u gave me , talks abt H815 mine is H818p .. would it work still ?
update
I successfully flashed it using LGup software .. all went aright , 100% ... phone reboots then comes that green android robot , then comes LG logo for a while and then everything goes black , like phone totally shutdown
Of course it won't work as per my post above. Hundreds of posts on this so not sure why there is a need for you to be different and create new thread? Is the search button not working?
Everything you need to know is here: http://forum.xda-developers.com/g4/help/recover-data-bootlooping-phone-t3313869
Download the files and read the instructions, it does say what models are supported and what not. Big cored disable tool is not a guaranteed way that you'll recover your phone but if it is outside warranty then you have nothing to lose.

Go into recovery and reflash your rom again. As long as you do not wipe all your data will remain

Ok then what's your first 3 digits of your serial? You may be another victim of the ilapo / bootloop issue.

It's bootloop issue,I think.i had bootloop issue,so this "flashing all kdz I can find for my phone" is what I did-and nothing helped,always never-ending boot or bootloop or nothing.Only way to make it work is,flash 5.1 kdz for your phone with LGUP(you need unlocked bootloader for this),and than flash "disable big cores on 5.1" file using LGUP.then it will boot.But it's still broken phone,TWRP won't work and custom roms/kernels won't work.

The infamous boot loop issue is a hardware issue so anything you do with the software should not trigger it.
