if its booting and crashing it looks a software problem to me why dont you flash a recovery and format everything then flash maybe a custom rom like CM13 try it if it works
if not then try again flashing factory image

Tried both of those already. It just randomly crashes and sticks at boot still. I'm using it right now but it crashed right before I saw this post again

[Solved] Help - Endless Bootlooping

Was running stock ROM rooted and everything was fine until I restarted the phone today. Started to boot loop and hasn't stopped. I've tried restoring backups, installing a ROM fresh and nothing works, just endless boot loops.
What else can I do?
Edit: Did the second option in the link below and it worked like a charm:

Have you tried to go into recovery and did a "Factory Reset" yet?
That usually works.
Good luck!

Yeah, reinstalled entire ROMs and no luck.

Sounds like she's bricked unfortunately. Might have put an incorrect kernal or flashing something that wasn't supposed to. I bought a bestbuy warranty and it just saved me, because I made an incorrect flash. It was hard bricked. Nothing I did would fix it. Improper kernals can fry CPUs, and if you're odining your stock firmware from sammobile and it still is looping, chances are that's what's happened.

My Note 3 suffered a few random boot loops out of the box. Then it ended up in sheer boot loop hell soon after it was rooted. At first, I too thought I had done something wrong until seeing all the posts about unchecking "Always Allow Scanning".
After the phone spent a solid 12 hours rebooting over and over, never getting past the T-Mo splash screen, it finally came back up. I unchecked "Always Allow Scanning" in the WiFi settings, and it's been fine ever since.
It would get quite hot during the boot loops, almost too hot to touch, while draining the battery very quickly. I plugged it in and set it on the fan in the top of my computer tower to keep it from frying itself.

Is your Knox flag already tripped? If so, I have a guide somewhere in here...
http://forum.xda-developers.com/showthread.php?t=2545009
I had same issue. Heimdall fixed it. Try it out, let me know. I have a lot of downloads, but no feedback. I need to know what other sorts of issues it can recover...
Recommendation though is to try the Bootloop recovery first just to get into a good recovery position, then wipe pretty much everything, and perform the stock restore.
When the stock restore hits, it runs its own little recovery script automatically fixing bootloop issues. You can root and do whatever else you want after that... Good luck.
try this it work for me

This worked! tried the second option since it was easiest and it saved my phone! Thank you so much!

Would like to know what happened?

I was using my phone flashed with Mokee Nightly rom and everything was working great until the screen stopped working for no obvious reason. It happened yesterday, I tried to use the phone and the Home button didn't open the screen anymore. Then, I tried to reboot the phone but all I could see was the blue led flashing as if the phone was booting but there was nothing on the screen. When I got back home, I tried to repair the problem and I was able to enter download mode, so I used that opportunity to reinstall the factory firmware with Odin. I was able to get it working but I'm just wondering what was the cause of this? I know I'm a serial flasher so maybe something got ****ed up while flashing it and it caused it to bug later?

With custom ROMs, especially nightlies, errors like this are not to be unexpected. Recall it is still undergoing development and may not be bug-free. If you must stick with this ROM, I'd suggest you wait for the stable now that you know what may happen.

Stuck in Boot loop after weeks of normal usage

Hi.
I have a problem with my D855. My phone is rooted and runs the fulmics ROM. Everything was working fine, , on Fulmics 5.3, except than one day, I was using my phone normally and then it crashed. I saw the phone rebooting, but for some reason it got stuck. The phone tried to boot unsuccessfully until the "firmware update" went through, after what it reboots again (unsuccessfully) and so on.
At that time, I was able to access twrp, do some backup, and flash properly with a downgraded version of fulmics (from 5.3 to 4.1).
It was able to boot again and use my phone like before. Yet, after one month of usage, the same problem happened on version 4.1. The phone crashed and now cannot boot.
Any idea of where it is coming from? Should I go back to stock? Should I contact customer service?
What did you do before the phone crashes ?
I think you probably should flash the stock ROM and wait for an other crash... or not.

I haven't done anything special. I think that the first time I was playing on candy crush. The second time I was just looking at pictures in my gallery.
I was using the ROM without any tweaks or extra modules such as Xposed. Just regular use.
Update on my situation: I switched back to stock ROM and it seems to work OK for now (it has been 4 days). So I will wait and see if new problems happen. By the way, it was extremely difficult for me to get back to Stock directly from fulmics ROM. I tried several methods that I have found on xda based on LGUP or LG Flash tool without success. For some reason I was not able to connect the phone to my PC in download mode.
The only way that I found was to use a nandroid backup that I did just after rooting the phone and that was based on stock ROM.

You can also use the Stock rom flashable from twrp. So you can wipe the system partition and get a "better situation" than a nandroid backup that should be with an old version.
Or use this that has also root and other improvements.

Same problem here. Normal usage suddenly started to reboot and now it's stuck in boot loop
Coming from Fulmics too - stopped working one fine day.
Now, continues to boot-loop at the initial LG screen. Trying to get into the recovery shows me the the 'Factory Reset' screen, but beyond that leads to boot-loops again. Even the Download mode loops!
I'm at my wits end without a solution in sight.

Thank you for this advice. I was able to update my stock ROM after the Nandroid backup through LGUP, but your method would have been faster.
But anyway, I am waiting to see if I am stuck with bootloops again, using non-root stock version, so I can send it to customer service if this happen again.

Are you using Fulmics ROM as well? Can you have access to TWRP? I was able to connect to a PC in the recovery mode and to transfer files before flashing, in case you need some basic backup...

Silly question, but are you sure that you selected "Yes" when the screen asks you about factory reset? you have to press "volume down" and the "power button", since the default answer is no.

Yes, of course I was able to access TWRP successfully earlier.
Curiously enough, the phone boot-loops in regular startup, Download mode and trying to get to recovery. However, it doesn't restart itself and fall into a loop, while on the Factory Reset menu. Am I correct in assuming that the battery could not be the root cause of the overall problem? Because if it was, it would likely loop even on this Factory Reset menu as well as far as I understand.
Unfortunately, the phone restarts as soon as it lands in the Download mode so I cannot even restore to stock.
EDIT: Okay, weirdly enough it just booted and reached the homescreen before restarting again. What I did was let it charge to a 100% and tried booting while plugged in. Could it be the battery after all? Though this exact set of steps hasn't been helpful before.

LG G3 bricked???

Hello everyone
I am writing this post to ask for help. I think I may have bricked my LG G3, and I can't fix it :/
I was trying to wipe everything, to later install a Fulmic ROM (6.6). I wiped everything by mistake after a factory reset, and since, I can't flash any new ROM :/
I am using TWRP 3.1.0, and I can mount the device and the sd card to the computer, and move ROM files onto the SD card. However, when I go to install, and after selecting the ROM (FulmicsROM-6.6Zip), the phone crashes... It runs something and when it reaches the part where it is starting "aroma installer version ...." the loading progress bar freezes and after a few seconds it crashes, rebooting into the LG Logo and stays stuck in there (if I didn't remove the battery I would assume it would stay there for ever, but without removing the battery, it stays in that LG Logo screen without much happening until I run out of patience after several minutes).
I tried install the previous ROM (Fullmics ROM 5.0, which was my previous ROM), but the same thing happens.
Has this happened to anyone? Does anyone has any idea how to fix this? It would be very appreciated if anyone could spare some moments to try and help me sort out this...
Ok, so another update on the situation (but not a good one )
I downloaded another ROM to test (CloudyG3), but unfortunately, the same situation occurs. The phone starts running the ROM after install and soon after that, once it is getting ready to start the AROMA installer, it crashes, and reboots onto the LG Life's Good logo and stays stuck in there
Has this happened ever to anyone? Any idea on how to sort this?
