OK so I have an H815 USA from the dreaded S/N . 505xxx series. It was working perfectly fine until it decided to freeze and reboot.
It did so over and over . It would always boot into homescreen. wait a few minutes and reboot.
I tried recovery (hard-reset) . no luck
I tried using LGUP method to flash v20D KDZ and the phone booted fine till homescreen and then after a few minutes. reboots again.
What is the plan of action here ? I am certain that this isnt the dreaded bootloop people are talking about because I can get to homescreen. Am i right ? If so, then whats teh plan of action here ?
Congrats you got the famous bootloop issue.

Try a factory reset without any apps and see if it does it.

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..

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)

Hi Guys
I got a problem. after i flashed Fulmics ROM and used it about 2 month i got wierd problems like brown marks on my display or sometimes reboots. I thought that it wasnt major so i ignored it but now my phone gone crazy and an reboot takes 10mins,that it cant detect my SIM-card and also that it reboots again. I flashed various roms like AOSP,Stock and CM 14 and it is the same result but what makes it wierd is that when i boot to recovery the phone doesnt reboot or so on like it was before any suggests how i can deal with it?
I'd start with a new battery if you haven't tried that already. The G3 goes crazy when a battery goes bad; no matter how full of a charge it has.

Greetings and Happy New Year.
