Stuck at LG boot screen - LG Optimus G Pro

Hello all,
I followed the thread to restore my device to factory settings, however when I finished everything, the device keeps stuck at the LG bootscreen after playing the boot sound.
Whatever I did, it never finished booting. I restarted, I re-formatted, I left it for 30 minutes. Nothing.
Any input will be much appreciated.
Thank you.
Edit (Update): Took it back to LG repair center. Let's see what will happen.

[Q] G4 bricked itself stuck in bootloop factoryreset doesn't work

Hi all,
yesterday my phone ran out of battery. I plugged it in(original accessory) and started charging.
After some minutes it started it self( as usual I guess). However it got stuck on bootscreen( boot animation) and restarted.
I left it plugged in over night, but nothing changed. This morning I tried to do a factory reset via hardware buttons and it got stuck there as well.
It restarted itself and nothing changed.
Is there anybody who has an idea what to do?
Thanks in advance.
have a look at this thread :

I saw that, since I already returned the phone to LG it is obsolete now. Thanks anyway

LG G4 stuck in a different kind of boot loop.

So I have an, I beleive korean h815, I have been rooted for a couple weeks now, nothing else done to the phone. Today all of the sudden it stays on the LG splash screen. Very occasionally it'll start up and say "android is updating" but then it reboots the splash again. Is there a way I can just wipe everything and start like from factory again? I've tried the factory reset from the power+volume screen, I got to that screen, but it didn't do anything.
correction, it says twn on the box, so i'm guessing it's taiwan.
I found the thread on using LGUP to install kdz's. Went with the 20c kdz. Phone went to restart and it's just sitting on the screen that says LG. No animation or anything. Someone please help.
I had to buy am LG g stylo to get me by. I really want to fix my g4 and return this thing.

Can you tell us your android version? I think i have exactly the same issue which is quite annoying.
Each night i put my phone in the power plug with flight mode ON. In the morning, when i remove the flight mode , the phone restarts and falls into bootloop. Happened 3 times exactly the same way. I went for PCB replacement the previous week and i got a PCB starting with ser. No 601xxx. Today morning when i removed the flight mode i got a bootloop again. I am sure that this is caused by the V20D version that i installed the last days.... LG messed up again...i have a bootloop each week..
Not sure. But this is staying on this screen, it doesn't restart and stay on.

LG G4 H811, crashed and bricked?

Hello to all of you who's reading, I ask for help from all of the skillful and knowledgeable folk in this wonderful community, I have a LG G4 phone that ran on CM.13, everything was running fine up until two days ago, phone just froze for a minute, nothing was responding, it crashed and LG logo came on, attempting to power on, but 10-15 seconds later it goes blank and lights up LG logo again... Now I've tried getting into TWRP but factory data reset msg comes up, after hitting yes and yes screen lingers frozen for another half a minute until LG logo shows up. I can get into download mode and tried flashing a stock image with LG Flash Tool 2014, it looked like it went through successfully but ends up doing the same thing... loops without ceasing. Do any of you have any idea what is going on and how can I get it fixed? Thanks for reading!!

Black screen after LG boot screen

Hi,
Today while browsing my stock LG g4 (h815) suddenly rebooted. It showed the LG boot screen for a while but then ended up with a black screen. The power button does nothing. If I remove and insert the battery the power button works again, but I get the same result.
I can boot to (stock) recovery OK and if I connect it to a pc it shows 100% charge. I tried using recovery to reset everything but no change.
I am on holiday so can't easily send it in for repairs. Any ideas? I do have a Windows tablet pc with me with ADB on it.
Search "bootloop" in G4 forum.
Warranty is the only solution.
But this is not a boot loop? It seems to boot normally and then goes to a black screen, it doesn't reboot. I direct about the boot loop but from the videos I could find it looked like it kept booting.
I guess I was wrong trying to start it today it boot looped a few times before the black screen. Guess I will try disabling the big cores so that I will at least have a phone until I get home.

LG G3 D855 Stuck in Weird Bootloop...

Hey! Check the bottom for TLDR.
I have had my G3 since they came out (have the 2GB, 16GB RAM version), and even got the G4, but remained with the G3 since it didn't have any issues with rooting and recoveries...
Anyways, I was talking to my brother on WhatsApp yesterday and ended up checking out my Hangouts messages at the same time. I believe I accidentally hit the camera feature on Hangouts, and then everything froze. I could still talk to my brother, but I could not get to the home screen or even change from looking at Hangouts. I turned off the screen in hopes that I could get back in, but when I turned the screen back on, I could not log into the phone (I do not have a pin or password, it has no lock at all).
After a few more minutes talking to my brother, it suddenly shut off. When I tried to turn it on it went into a bootloop where the front light changes different colors, and the LG logo continues to show that shine going around the logo.
I was able to get into download mode and went ahead and tried to flash a KDZ as per instructions (I have done this in the past). The install would complete and the phone would give the prompt about updating all the apps. Once that was done, it would show the LG logo and again for about ten minutes. Afterwards, it would get stuck in updating all the apps again and performing the same process...
I also tried using the LG PC Suite and trying to "Restore upgrade errors", but every time I would click that option, I would get a Windows error that something happened and close out the program (it never recognized the phone). I then used the LG Mobile Support Tool, which allowed me to perform an update for the firmware. It too completed, but then went back into the process of updating apps, showing the LG logo, then looping.
The final thing I tried was doing a Factory Reset. I was able to get to the area, and when selecting yes, it immediately went to the LG logo and "Life's Good" sign, which it would never get passed. This is also what happens when I try to turn on the phone and wait.
I contacted LG, which was pointless, as I expected. They wanted me to go to a local repair shop, which is of no use to me if they can only perform the same things I have done.
TLDR: My phone can get into download mode and the Factory Reset area, but flashing stock firmware, or performing the Factory Reset, still leads me into one of two bootloop situations. LG PC Suite and LG Mobile Support Tool seem to be of no use.
Does anyone have any suggestions? Is there anything I can try that I haven't?
Thanks in advance!
