Boot Loop after factory reset - G3 Q&A, Help & Troubleshooting

D851 phone running stock lollipop
I had an issue the other day where my WiFi and Bluetooth were refusing to connect and just said "connection not allowed" so I tried a few things and then resorted to a factory reset.
Luckily the factory reset fixed the WiFi issue but now another issue has come up, an almost endless boot loop.
Occasionally the phone will actually boot but it never stays on for long even when plugged in. I've tried factory resetting again but to no avail.
Prior to this issue my phone would have the occasional random reset but nothing too frequent, my battery is relatively new but I'm not ruining out the possibility of a faulty battery and am in the process of getting a replacement.
Does anyone have any ideas what this issue could be caused by and how to fix it? The fact that it occasionally boots makes me think it IS a battery issue but I'm a complete noob to this kind of thing.

Phone Stuck In Time Warp

So I have no idea what is happening with my phone, but it seems to be stuck in a single moment in time. Any changes that are made, texts received, apps (un)installed are reverted on the next reboot.
This wouldn't be a problem usually, except my phone randomly reboots when I'm doing normal things. It's become pretty unstable and pretty much is unreliable.
Before anyone says "just factory reset it", I can't. Any attempts to factory reset, fastboot flash, ODIN, CWM reflash, or OMAP flash (I got desperate) SAY they are successful, but the phone reboots to the same state as it was before.
I'm essentially at my wits end. Any attempts to return my phone to stock do nothing.
Any ideas or thoughts?

Strange bootloop

I restarted my phone a week ago, after that the phone would stay at the boot animation and would not load.
I found out that giving it a factory reset fixes it.
But here's the catch, if I restart the phone, it gets stuck in the bootloop again.
I even switched roms and it still does it.
Any ideas?
Nevermind: I fixed it. Apparently the SD I had was ****ing things up.
Should have figured it since now that I recall, my uncle left it home after it ****ed up an SII he had.
Please detele thread, mods.

Software bootloop 5.1.x

I believe there is an issue with one of the nexus 5x updates. I see several threads here and most people are quick to say its the old hardware bootloop issue. But, I don't believe this is the hardware bootloop issue since I was able to fix it once with factory reset. And this is a replacement phone that I got after the orginal had the hardware bootloop. So I'm looking for some confirmation that there is some sort of software bootloop issue with one of the nexus 5x updates.
I got into this mess because, I put off updating one of my phones for a while and recently I started updating several updates. I think one of these updates in conjunction with facebook or some other social app causes phone to crash and then be unable to boot.
I wiped cache and it didn't help. I did a factory reset and got it working again. Then I started updating again and the same thing happened. On another nexus 5x I don't use social apps and I never had this problem. I'm trying to do another factory reset and going to update up to the latest patch without using any social apps.
One symptom is that if u go into recovery mode, it says "no command". To get past that, you have to hold power for like 3-5 seconds and then while holding it, press volume up.
Now to do some factory resetting...
Okay I am not able to get into recovery anymore. Maybe the first time was luck that I was able to do a factory reset. This is looking like another hardware bootloop now.

LG G3 D855 blackscreen right after booting logo

Okay, so i have an LG G3 D855, few months ago it worked like a charm.. But then shortly after i started noticing random reboots everytime during using apps. Then it went in bootloop. I tried to turn it on again, entered recovery screen, choosed factory reset and it did, but then it went through the same process, random restart. Eventually stuck up in factory resetting screen. However i think i made mistake when the phone freezed in reset screen : pulling out the battery. later it lost its IMEI & kept heating up (probably tried to find its cellular framework of some sort).
Days passed, several factory resets has been done. Now the phone's at its worst state. It refused to get past the boot logo. everytime it finishes booting, the display just goes black, tried to plug usb charger, chargin indicator doesn't want to turn on, neither after i pulled out the battery. I have to leave it a few days to get it working again, but it keeps persisting.
Addition : The phone's also feels warm post the blackscreen.
Any thoughts whether can this be fixed or i have to replace something inside the phone's board?
thanks in advance.

Reflash with lgup.
Remove the SIM card and the memory card. try again. Full wipe system data ...
I've had the same problem. I've tried. Worked
found the problem. memory card
EDIT: Some kind of voodoo happened right now! I was about to unbrick again and wanted to give the phone a try to boot before. And it did! So no problem at the moment, but still a strong feeling of uncertainty...
EDIT: Phone is still randomly rebooting and gets stuck in bootloops

Hej guys, I really need your advice,
but first things first: Thank you very much for all of your wonderful work on custom roms and further support of older devices. I've been reading here for a few years now and was more or less happy to have up-to-date-roms for some of my phones.
Now I'm facing quite the same problem like OP did / does. Everything started with me, following this guide to root my D855 (coming from stock rom) and flash TWRP: you tube.com/watch?v=8VOgM3jLas4 (Note: The guide told me to flash "3__HacerPermisivo.zip" for updating the kernel, which I did.)
Next, I flashed a newer version of TWRP ("twrp-3.2.3-0-d855.img") than the one provided in "2__AutoRecMMD855.apk" by the guide above. I wiped dalvik and cache and after that, I flashed "lineage-15.1-20190410-nightly-d855-signed.zip", wiped dalvik and cache again and flashed "open_gapps-arm-8.1-pico-20190411.zip". I wiped dalvik and cache again and told TWRP to reboot.
Here is, where problems began to occur. The phone got into a bootloop, showing up the LG splash screen again and again instead of booting into LOS correctly and set it up. At some point I decided to remove the battery. When I did, at the same time LOS was just going to load, which I saw because of its beginning boot animation. So I screwed it up right at the wrong moment, I guess.
From here, the phone bootlooped every time, I wanted it to start. No battery acrobatics helped and on top I couldn't get it into recovery mode. Any attempts ended in bootloops. I think, this might be what is called a brick / to brick your device, isn't it? I found this guide to unbrick a D855 and followed its steps: open -freax.fr/guide-unbrick-your-lg-g3/
Believe me, it was a real pain in the ass! Because of me, messing up something or the phone getting stuck into a bootloop during the unbrick process, I had to do it 4 to 5 times until success... I have to say: I didn't follow the last steps beginning from "Root". Instead, I followed the guide from the beginning of my post.
Finally, I got "lineage-15.1-20190410-nightly-d855-signed.zip" and "open_gapps-arm-8.1-pico-20190411.zip" to run. I set it up and began to load some of my apps of my Play Store collection. While downloading, the phone froze, crashed and began to bootloop, from here unable to boot normally or to get into recovery mode. So I unbricked and flashed again (again several times because of bootloops before LOS first set up). When I got it to work again, I was able to install my apps without being trolled by the phone again. But scrolling through the eBay app froze the phone and it began bootlooping again...
You can believe me, I was about to throw the D855 against the hardest piece of wall, I could possibly find in my rage. The reason why I didn't give up at this point is, that I LOS-rommed two other D855s just a few days before. Those were my mom's and my girlfriend's and they work fine until today. I bought this third one for myself, because I was impressed, how good LOS worked on the D855s. On top I wanted to get rid of my Samsung Galaxy S4 (GT-I9515), because LOS kinda sucks on it, but this is another story...
So I figuered that the earlier LOS version I used for the women's phones, could solve the problem. So I unbricked again and flashed "lineage-15.1-20190327-nightly-d855-signed.zip" and "open_gapps-arm-8.1-pico-20190329.zip". And hell yeah, that did work! No bootloops, eBay worked fine, just everything was as I loved it on the other phones, I flashed. Until tonight. I've been lucky for almost two days, but tonight this happened: I plotted a route in Google Maps and saved it as a shortcut on my homescreen. I closed Maps and tapped the route icon. Freeze - crash - bootloop - no recovery mode! I wanted to start crying, because Maps has already worked fine yesterday. And it still does on the other two phones, which run exactly the same rom...
So now, I'm sitting here, not knowing what can be done further. I'm not a programmer / developper or any of those cracks providing us the newest software for old phones. So I just can do wild guesses. Maybe the moment I removed the battery the very first time after flashing messed something up very deep inside the phones internals and it can not be cured any more. Maybe some of you guys have experienced similar things and know a tweak or a simple step, I forgot. Anyway, I hope I can use my phone on LOS some day which I bought especially for this case.
Keep up the great work, folks!

I ordered a new mainboard. It should arrive within 3 weeks. I'll keep you updated.

Question Bootloop when low battery

Since not so long ago I've experienced the following:
If I leave the phone two have low battery like 10% when it dies it enters a boot loop I cannot stop and I just can only plug it in and wait while it bootloops without being able to stop it and a long time later (20/30 min) it will finally boot up, last time it had 30% battery when it finally booted up.
What could it be? It may have been the last update? Has anybody experienced this?
If you did a major firmware upgrade without a factory reset, do a factory reset now.
Otherwise clear the system cache.
It it persists, factory reset.
If it still continues it maybe hardware. It could be corrupted firmware but trying to reflash may end up causing it to brick if it acts up during the reflash. Consider your options carefully at this point especially if under warranty or insured.
I have the same thing. The phone just starts to vibrate indicating a startup, then after a few seconds it vibrates again, and continues in this loop. The screen doesn't display anything.
I'm having the same thing right now, I tried wiping the cache from bootloader and charging the phone to 100%, but it doesn't seem to be fixed
Maybe on an unlocked bootloader it doesn't work? Something related to offline charging?

I have not had it happen lately the other day I had 5% battery and it worked fine.
I think it might be an unsupported charger?
