LG G4 Stuck at Logo Problem - No download mode - G4 Q&A, Help & Troubleshooting

Hey, my Lg G4 H815 is dead. It got a bootloop at the logo. I only one got it to the startscreen but it died again.
I tried every thread offered I found. I ended up with going into download mode and install back to stock. This didnt work with lg flashtool so I tried the method with lgup. Nothings changed. What now happens is that when trying to get into download mode, it says some seconds donload mode and swithes back to the logo. Since then I dont even get into hard reset mode.... So can I through it into my trash can? Or does anyone know how to fix this? I would be thankful for every answer.... have a nice weekend you all

as long as the phone is for your region LG should repair/replace it. I just had the same issue with my H811 and despite it being 1 year and 2 months old they repaired it free of charge.

weird bootloop broblem

Hey!
two days ago, out of the blue, by device restarted it self, and started to to it every few minutes.
after that, it just stuck in bootloop tho it was able to turn on for few minutes once or twice,
I tried to recover to factory settings from the phone, re flash the latest version with LG bridge, and use the flashing tool to reflash the kdz.
it always goes back to booploop(I think)
download mode works and not crushing.
any ideas? I
G4 h815 twn
Unfortunately, the same thing's been happening to a lot of people lately. I'm getting bootloops on my G4 but it hasn't happened enough for it to be a problem. Once it becomes more of one, i'll send it in to LG under warranty. I would suggest you do the same too (LG warranty is 15 months from the month the phone was made - that info can found on the outside of the original box) Good luck!

Boot loop problem

Hi !
I'm having a big problem right now. Few days ago, I tried to Root my phone everything was fine. The next day I wake up and go on my phone and there is a boot loop when I try to open it and it never ends. It's a loop at the LG life's good logo.
Few things I tried so far before coming here:
1) I tried all this :
http://forum.xda-developers.com/showthread.php?t=2785089
When I do it with LG Flashtool 2014 it goes to 4% then it stops/crash.
When I try with LGFlashTool I get : Model Information: Check FAIL! (but I put the good model in the files)
2) I tried a hard-reset but when I do the hard-reset it goes back right away to the Boot loop.
3) I tried with LG PC Suite, but the it says Mobile Device not found so I can't get it to repair with LG PC Suite.
I don't know what to do anymore.
My phone is a LG G3 D852 (Canadian)
Hopefully you guys can help me out here. Thanks a lot
Well apparently doing it on another computer fixed the problem!

How to brick LG G3 D855 ?

My phone was bricked hard and i had to us many tools to unbrick it and it worked and i have opened download mode band started lg flash tool but every time it reaches 100 the screen goes black and lg flash tool fails to flash and the g3 returns to 9008 again and i restart doing it from the beginning for about 7 times.
The problem is at the last time i have unbricked the device with a different .tot i guess and it did the bad thing.
My phone shows the lg logo of boot for a second and turns black. Then comes agin for a second and turns black.
And the sequence have going for about an hour
And the download mode do the same and its not opening even so i guess that the best way to solve the problem is to brick the phone again.
But this time its my choice to.
So i need help
I think you are flashing wrong tot.make sure the model of your mobile and then flash the exact tot.

Dreaded Boot Loop

Hi,
I was using my G4 H815 SEA version last night when it suddenly rebooted, it's been running 20j with Genesys mods for Bootloader locked devices for about 6 weeks with no problems. It now only boots as far as the first LG Logo screen.
I can't reach recovery mode.
I could access download mode, however after trying to re-flash using LG UP, my PC no longer sees a connected device..... same with LG Bridge, same with LG Support tool. USB driver is installed and verified by LG support tool.
I bought this from value basket but live in the UK - to date Valuebasket's customer service has been the worse I've ever known so I don't think they'd be any help in getting this damned thing fixed.....
Any ideas on how to get this thing back to life?
Thanks :good::good:

Help my G3 might be hardbricked (hopefully only softbrick)

Hello, I would like to ask if my LG G3 is softbricked or hardbricked. It has been a long while since it decided to boot loop. I tried to fix it but got no results. I tried to factory reset it, but the next day it didn't turn on anymore and got stuck in the logo. Note : the phone was experiencing some heating issue before it decided to screw itself up. I tried numerous troubleshooting from the net, none worked. I also did try to reinstall the firmware to stock again, it did boot but it can't get to the home screen. I then factory reset it again and tried using another firmware also built for my phone (it's LG G3 D855). It failed again at 33% while it was in the firmware update mode. Now that I have left it for a solid year, I thought that it would be nice to try again. Which I did, but it couldn't charge anymore and it cannot boot to the logo. I tried to go to the download mode but no response. I tried connecting it to my computer, but it only detects my phone as a charge only device, it also detects it on only several random occasion. I hope this is a softbrick and it can be fixed at home so I don't need to go to the store to repair it.
I'm sorry for the long explanation, I had been trying to revive it for months now and had no luck. How do I fix this, at least how do I get to the firmware update download mode again? I really really hope that anyone can help. Thankyou so much in advance.
