Stuck in Boot loop after weeks of normal usage - G3 Q&A, Help & Troubleshooting

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.

Any way to re-charge the battery if stuck at boot ?

I have a E988 indian version which is stuck at boot with the "secure booting error cause : Boot certification verify",
I can get only into download mode and no recovery or can not boot into OS,
Earlier when i was in the situation i could get into download mode and use LG support tool to flash stock, But now i am getting battery low error..
My question is "Is there any way to recharge the phone if stuck at secure booting error or in download mode ?"
I tried offline KDZ flashing also but there also i was getting battery low error.
Thanks
If you can get to recovery. Mine charges while in recovery.

Try a factory reset by holding power and volume down at the same time. Press power button to confirm reset. If you do this, sometimes it will reboot you in to recovery, if not try it again and this time manually enter recovery.

If i try to factory reset it initially asks for do you want to go ahead with factory reset and after i confirm the same old error of secure booting comes in... (factory reset does not happen), And i can not go into recovery mode directly using the volume up and power button...

I hate that stupid low battery message. It's so dumb that they do not allow you to continue at your own risk. I have also had this problem going from AOSP back to stock. The only safe way to do it is using LG Flash tools first, then flash one of those stock zipped roms. Now it is too late for that. Do they sell your handset in the country you live in? If so, they can fix it in store in most cases. For me, they don't sell this phone in my country, I was just lucky enough to be able to continually try to factory reset and then my phone randomly booted in to recovery (don't know why or how, it just did). After that, I flashed lockified TWRP and CM11 again.

Hey, My G Pro is on Miui and everything works fine on it. I can enter recovery mode and all that. But, I want to revert back to stock and this low battery error keeps popping upon during offline flashing. I have seen your method for bypassing it, but I have not found a solution. Is there anything else I can possibly do? Thanks!

This is what I did by accident
The problem, as I see it, is once you root your phone and put the custom recovery on it, CWM or TWRP, it overwrites your factory recovery. I tried using a 10k flashable zip I have to get my phone back to stock. BUT once I tried to get the OTA update to 10P, as another member here pointed out, My phone boot looped. So my question is, is there a way to remove the custom recovery and restore the stock recovery WITHOUT having to go through the PITA process of using flash tools? If there is a way it would save people countless hours fixing their phones just to get an update.
I know many of you don't see this as an issue because your whole point IS flashing new Roms. But from everything I have seen of this phone it's more trouble than it's worth. This phone is so very picky it's ridiculous. I just wnna get the damn 4.4 update, have it rooted to remove bloat, and call it a day. But to answer the OP question, you always have the option of buying a battery station online and charging your battery that way.
Fixed low battery error
My friend managed to fix the low battery error. He tested the method on my phone and during flashing the error did not show up. Will be creating a new thread which fixes the low battery warning soon. Stay tuned !
Sent from my LG-E988 using xda app-developers app
Nice work. And that thread will definitely help allot of others with that issue.
TL;DR
Aside from all the technical stuff, and since the g pro has a removable battery(thank god for that) there are several chargers that you can use which charge the battery outside of your phone. Here where i live (honduras) I have seen quite a few and had one myself(used it to charge spare batteries).

[Q] Can't boot into recovery or OS

First of all, thank you very much for taking a look at this.
This message has been deleted 4 times by the text editor. Hopefully this one will sound a bit more polished as a result. Over the past few days I have been slowly installing cyanogenmod 12 to my Note 4. I have been dealing with issues installing it from the get-go, and quickly became familiar with restoring the stock ROM with Odin as a result. This latest time it seems did not go as swimmingly as they were before. The last time I tried flashing it back to the stock OS with Odin, it wouldn't boot into android afterwords. It now flashes the boot screen, doesn't even show the sprint bootstamp, shuts down, and restarts again. My multiple days of google-fu has failed me and I believe you guys are my only hope.
Did you try flashing stock ROM through Odin mod

Sorry, I should've been more clear here. The last time I tried flashing it back to the stock OS with Odin, it wouldn't boot into android afterwords.
[Solved]
For the next person who makes this mistake, remove the battery for 30 seconds.
It seems I was too occupied with the more complex solutions to notice the simple one in front of my eyes.
Can you get to recovery and factory reset?
Tried without sdcard?
Odin TWRP recovery and wipe everything, power down and then Odin stock tar?
Not necessarily all the above at same time but in progressive manner getting more aggressive each attempt.
While in CM12, was there anything you might have flashed that started some problems prompting a return to stock? Xposed framework? Restore a nandroid?

[Q] Loads of Problems (rooted, unrooted, firemwares, flash, stuck on logo screen)

I'm having one hell of a time with this tablet. This is pushing a month and I'm still not satisfied with my tablet.
Tonight I finally tracked down what I had hoped was a stock firmware for my tablet. Halfway through the download it timed out and when I went to download it again, the same thing happened.
So I tried to take my tablet that isn't "properly rooted" anymore and use Odin 9, instead of Odin 10, and place kitkat on my device rather than be stuck with Lollipop 5.0.2. All of this because The Sims Freeplay app isn't working and I can't find another soul on the face of the earth who can give me an answer to why this is happening.
Now I'm stuck on the samsung logo. I managed to get it back in download mode and that's where I flashed Lollipop 5.0.2 through Odin 10. I figured that would solve my problem. It didn't, but at least I got TWRP back on my device.
I never recovered anything that came with my tablet. I did not think I'd ever go back to unroot nor did I know how to back it up in the first place. So there's nothing in my recovery I can boot from. So what I did was I came back here and I downloaded the recovery for TWRP. I flashed it from my SD card, it told me it was successful... now what? I've rebooted and my device still loads to the samsung logo...and just stays there. The little confetti animation happens behind the logo, but that's it. It doesn't turn off. It doesn't reset itself.
CAN SOMEONE PLEASE TELL ME WHAT I'M DOING WRONG?!
I've already voided the warranty on this device and I regret almost daily that I decided to root in the first place. I say this only because I think rooted devices are top-notch, but I haven't been having very much luck with them. It took me a week to root. When I finally rooted then my favorite app game stopped working. Then I figured I could flash the stock firmware easily (but it seems like every place I go to find kitkat or even stock lollipop I can't find or I do, but files are corrupt or sites are full of ads).
I can't use my device at all now except click around in TWRP which isn't doing me any good.
I just want my tablet back. I spent 500 dollars on this thing and I haven't had time to even enjoy it. It's only two months old.
Please. Again. Someone HELP me. I want to figure this out and I don't want to accept that I bricked my device because I've watched plenty of videos on youtube and people are stuck with a phone that's resetting and all they do is fix it right there in front of my eyes.
Why can't I fix this? What is it that I'm not doing properly?

I just skimmed through all this reading, so I may have missed a few things. The thing I didn't see if factory resetting. You need to factory reset in twrp. Just go to wipe and factory reset. Now reboot and wait at least 20 minutes as it does take quite a while to boot.
If doesnt do, transfer a custom stock based ROM for your device (any KK ROM should do) to your SD card. Factory reset in twrp and flash ROM. Now reboot and wait.
Typically, flashing with Odin takes 20 minutes to boot up for the first time. Just be sure you factory reset.

Custom Stock Based Rom? Does that mean I'll push myself further away from a stock firmware? Also... where do I find one and are there instructions for it? I thought roms were firmwares up until like 4 hours ago and I've been reading of roots for a little over a month now.
I see you've got the same tablet. By any chance are you running 5.0.2 lollipop and do you happen to know having a rooted device is the reason why The Sims Freeplay won't get past it's splash screen or if it's the app itself and it's newest update that made it wiggy?
I'll flash whatever at this point, but my main reasons for continuing to mess with my tablet was because of not being able to play the sims on there. Every other game I play works.

The only thing I can suggest is download this to your SD card and flash it in twrp. http://forum.xda-developers.com/showthread.php?p=56345482
The Sims may not work because its uncomptiple with lollipop.
Simply, hit wipe in twrp, hit advanced wipe, and tick system, dalivk and cache. Then go back and install the Cm11 zip and reboot. Hopefully it gets you booting

I'd actually flash this as its more like stock just debloated.

You need to wipe system, dalvik, cache and data then Install via twrp.
Wait at least 10 to 15 mins after install for initial boot up.
For future reference whenever you go back to kitkat from lollipop you need to wipe the data and cache partition first.
By the way some apps and games do not work on rooted devices for security reasons.

I understand that. That is why I clicked unroot in supersu and tried the game app, but it still wouldn't work. On my galaxy note 3 I run 5.0 lollipop and my game works fine. My phone isn't rooted and I never decided to root it and then unroot it.
Is an app smart enough to know when a device has been rooted and if are those that hack their actual game on rooted devices uses cloak or xposed or both to by pass their root?
I rather be unrooted for the sake of the game, but how does one find the stock firmware? Or is it not possible at this point?
Sorry for any confusion.

Okay. I installed or flashed ironrom to my tablet from twrp. i followed the directions it told me and I decided to pick the regular rom above the custom one that was close to stock. Then it told me that it was going to reboot; which it did. When it came back it got stuck on the same samsung loading screen so I powered it off, went back into TWRP (because powering off now isn't possible, more like restart) and I went to "Reboot " and then I clicked "power off".
I guess I'll be waiting for 10 to 15 minutes.
I Pray I did this correctly.

Why did you reboot back into twrp? You should have just let it do its thing after it rebooted.
So for any others that may happen upon this thread.
What was your solution?

I did because I thought it had to be shut down before I powered it on and waited. I realized afterwards that you probably meant to just let it sit for 10 to 15 minutes.

Your solution.
cant reboot after failed encryption
I was trying to encrypt my galaxy tab s, which is rooted and has lollipop 5.0. Afrer reading encryption failed. I tried to reboot in recovery via twrp. My device doesn't reboot, it just acts like its going thru the motions. Only to return to twrp recovery menu. How do I reboot the system clearing the failed encryptions. I am a noob and any suggestions would be much appreciated.
You will have to go into recovery and wipe the data and cache partition then reboot.
It may take a while to boot up after that.
Well I thought my solution was using IronRom... but i'm not too sure now.
I just got back from work and I went to turn on my tablet and it took me to the same loading screen and then after about 5 minutes it tells me that the system can't respond. It asks me to click "ok" or "wait" ... clicking either just turns my tablet off.
Now the screen has dimmed. It's turning on when it wants and sometimes it'll show me the time in the upper right hand corner, but it won't let me do anything because it's a black screen.
What does all of this mean?
I just noticed if I click the "power button" it just flashes my tablet desktop then goes back to black, but it shows me the battery percentage and the time in the upper right hand corner...

Marshmallow Update followed by Bootloop [EUR]

I just got the official update to Marshmallow and I decided to just do it since it is official. It downloaded and then installed. Then it rebooted and showed that "apps are being optimized" screen and after that a bootloop of the lg logo. Rebooting doesnt work only if I take the battery out but afterwards there's still a bootloop. I also didn't do root or anything else to my device. I can not enter download mode or recovery either, but honestly idk if it has worked before.
Can anyone with probably similar experiences help me? Thanks in Advance from Germany

I have exactly the same issue. I have a German-bought LG G3 d855 updating this morning to Marshmallow. It is now caught in exactly the same boot loop. I get the LG logo, for a few minutes (the brightness changes during this time) followed by the "Android is updating..." app optimization screen which optimizes my 44 apps before going back to the logo in a constant cycle. Then my 44 apps get optimized yet again, and on it goes. I can't enter recovery, none of the button combinations has any effect. Phone has no mods, and was working fine before this.
Does anyone have any ideas?
Hi,
Similar issue here, my phone updated today (also no root, no mods) and for a couple of hours everything worked fine (just some missing apps after the process, but ok), then I went to flight mode and back and then it started with the reboot loops.
The reboots on my phone happen after some seconds in the home screen, so I have time to try to set it in flight mode again, and in some cases, after this it stops rebooting, but in flight mode, with no connections at all.
I'm trying to remove things to avoid doing a factory reset by now, removing cache didn't help...
Is your phone rebooting also after loading the home screen? or it just loops in the LG screen or in the apps update screen?
Hello,
I had the same problem. Just hardware reset the device and the device will continue from optimizing the apps
Instructions on how to hard reset see the video find on youtube "How to Enter into Recovery Mode on LG G3!"

I have a G3 european stock version, recently update to marshmallow (3 weeks ago). The pb occur when trying to connect to a open wifi network : suddenly reboot, then stucked in bootloop.
Is there any possbility of doing something using the "download mode" ? I really would like to recover photos in internal memory...

You can try "normal flash" at the first time, but if it doesn't work (for me it doesn't work) you will have to choose "CSE Flash" and it should work. But you will loose your personnal data. So be strong.

Bro Thank You so much ive been searching for solution the last 2 days and you finally saved my life Thank you Man !
i have the same problem....after the stock firmware has been restored,what method is used to get the proper working marshmallow upgrade?
I went from 5.0 to 6.0 using the LG PC Suite.
0 problems, 0 reboots, quick and fast. Did you update through OTA?
yes i did but still boot lop............is it the battery?
so ?
Same problem here, did you find a solution ?
New G3 from LG but back in bootloop after 24h of use.
Thank you.
I got the exact same issue, neither hard reset or flashing firmware works. Is there any other solution or should i start looking for a new phone?
Edit: Somehow it works just fine now lol. Tried flashing it like 3 times and hard reset twice and now after an hour of constant optimizing apps bootlopping i pulled out the battery for like the 100th time and now it works, what the hell. Looks like my G3 will die soon tho haha

Boot Looping Help Please

I purchased a 5x for my wife so she can get on Project Fi. They said it was stuck boot looping, thinking I could solve the problem.
Here are the basics.
-Yes, I can get into boot loader (the menu of start, recovery, etc), but I can't get into TWRP. Tried flashing TWRP a few times and nothing. SkipSoft recognizes that its installed though.
-After bootlooping for awhile, it will load normally and work fine. However it wants to update to the newest version of android. I run the ota and back to bootlooping. It will show the android dude and say "error". Will eventually start bootlooping and then boot normally.
-I have flashed different stock versions. I tried the newest, the second to newest and the last M available. All will flash but continue the bootlooping.
Bootlooping can be anywhere from 1 minute to 10+.
The device will also first display something like, "Your device software can't be checked for corruptions. Please lock the bootloader"
But it'll show up whether the bootloader is locked or not.
The phone will freeze at some point. Whether right away or after 5 minutes. It freezes and then restarts and goes through the bootloop again.
So what else can/should I do? I've never dealt with Kernels but wondering if the last owner did something to them. Is there a way to flash stock kernels just incase or is this done when I flash a Google Factory Stock Image?
Would flashing a non-stock rom be a good idea?
Thanks
So I tried sideloading. I was able to get into the stock recovery. I tried wiping cache and data, then tried installing the newest stock rom.
Everything seemed to work. Then I had to restart. A message popped up after the same "Your device software can't be checked for corruptions. Please lock the bootloader". It had the title in blue stating "Encryption unsuccessful".
Then said, "Encryption was interrupted and can't complete. As a result, the data on your phone is no longer accessible. To resume using your phone you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account."
Then there is a single button that says, "Reset Phone".
Problem still persists.
Help please...
Why did you bought a bootlooped phone?

When my Nexus 5x got into bootloop, I sent it to LG and they had to change the whole circuit. So yeah.
When you flash Google Factory Image, it flash the stock kernel.
If you have warranty, then send it to Google/LG. If you haven't got, then you're in problem. New motherboard needed, but it's expensive.
See the following thread for more info.

Hardware bootloop can't be fix by software.

Exactly. Everyone has either been able to get a replacement under warranty or was pretty much screwed if it was out of warranty.
