D855 keeps rebooting even after rom change and LG Flashtool procedure - G3 Q&A, Help & Troubleshooting

Hello,
my phone is stuck in reboot loop since yesterday.
I have this phone since 2 years. It was rooted and on fulmics 5.3. Since few weeks i had random reboots, more and more often, since yesterday when it became unusable because of the reboots.
It wasn't in bootloop, but the phone starts, the rom loads, and after some seconds it reboots.
So i changed rom, went on exodus, but the problem remanins. The rom boots, and after 1 or 2 mins it reboots, go in bootloop, then starts and reboots again.
Today i've made the Flashtool procedure to go back on stock, but the problem still remain. The rom booted, changed the language then rebooted again.
Wad can i do now?
Thanks

perhaps to be hardware problems, there are some parts of poor contact caused by repeatedly reboot

its not the problem of rom . its a battery issue
replace battery

Maybe this ^
I'm using phone connected to power and it seems to works!
Thanks!

Buy a new battery

[Q] Phone Keeps Crashing/Restarting (on any ROM I've tried)

So there's some issue with my phone, it started with an issue where my phone would crash, restart, and then go into a booting loop (the samsung logo part). Well after a few retries of installing that rom again (phantom blazer), after that very version of the rom had worked without an issue for 4 months, the crash/boot loop happened again. After this instance, reinstalling the same ROM would not get me into the android OS.
So I moved on to a new rom (paranoid android), which worked for a little while, and then had the exact same issue. After two times in a month of the same crash/boot loop, I moved on to a new rom (wicked sensations). So here I am now with the same issue, but it seems to have gotten worse. Now the crashes happen more often, randomly while in my pocket, and often when trying to place/answer a call, but the frequent crashes are without the boot loop and need to reinstall a rom.
I follow the installation instructions for each rom to the T, all the wiping of dalviks and cache, but the same **** keeps happening. Does this sound like a hardware error in my phone?? Should I return to a stock rom and see if my issue keeps happening? I'm in a rage at this point . Please halp.
I would try this link-http://forum.xda-developers.com/showthread.php?t=1904099. And like you said, see if problems continues. I think any ROM can and will reboot at some point, are you updating your ROMs as developers update them?

Have you considered your experiencing the 'sudden death syndrome' you may have a faulty power button it's a known issue with the S3. Sprint does repair or exchange the phone for this. It's exactly what you described it powers off and on. It can power up until the splash screen and it powers right down. It just so happens that you start playing with the power button when trying to go into recovery to flash another rom or what not and it clears the issue for a while. Until it sticks again. Just something to consider you can search it here under exactly what I called it 'sudden death syndrome'

Stock firmware crashes / custom firmware restarts every few minutes

Hi All,
I am not sure if this is a hardware issue that I am facing or what.
Basically I was running Linaro CM11 which was working fine, but I got a goo.im that a update was available. So I downloaded and flashed this.
Everything seemed fine except after 5 minutes the phone did a reboot, it started up fine and same thing kept happening. So I flashed back to the previous version but the problem persisted.
So I downloaded a stock N7100 UK vodafone rom, flashed this but while doing so it seems the usb cable I was usb wasn't 100% and it crashed mid flash.
I used a JTAG to get the phone back into download mode and using a new cable re flashed the above stock rom. since the any stock ROM i flash goes into deep sleep and usually WONT wake up.
So i decided to re flash CM10 stable, which does not suffer the deep sleep but does suffer with reboots every few minutes so tried CM11, also tried a few other ROMS and im suffering either deep sleep or a reboot.
What is wrong with my phone, second to this I cannot turn on bluetooth if I try to on stock or custom the phone either just toggles straight back off or freezes completely and restarts itself or stays like that just hanging.
Any help would be greatly appreciated.
Just to add to this post, iv tried Sammy 4.3, 4.1.2 & 4.0.1 I think on the last one all do more or less the same except they all crash loads on first boot. Some are unusable. Iv also tried Irish rom, France, Spain.
Same thing happens on all soon as the screen goes off it is almost impossible to get the phone to wake up. Also tried other kernels again with the same result or worse the room packs in.
Help :crying:

(Q) phone reboots after sony logo

Hello,
I have a xperia zl c6506 and I flashed/ installed candy5 to the device. For like a week and a half, it was working fine. For the first time , it shut down randomly and when you try to turn it on, it keeps rebooting after black screen. I held the reset button for like 20 seconds to shut it down. When I try to turn it on , it keeps rebooting.
What i've tried:
-Reset button
-Going into recovery twrp( tried to flash a different rom , pa 5.1) it turns off as soon as you install in twrp.
-Plugged in while in twrp installing rom( it was successful, as soon as I unplug the phone after like a minute reboot happens again.
I just bought the phone brand new, like 2 weeks ago, so I dont want to assume its the battery. Can it be anything else?
-Reset button
vibrates? how many times?

flash back to stock as best you can assume its the rom.. leave it plugged in and off for at least 12+ hours and then try to start it
try dirty flash the rom and gapps. Worked to me sometimes when I got bootloop. If that doesn't work, you'll have to make a clean install, unfortunately.

Soft-Bricked M9

I've had an M9 for 2-3. After the first year I got my phone, I installed a custom recovery and rooted it but later uninstalled root and custom recovery. It has been fine ever since except recently. Last month, my phone randomly crashed for the first time and got stuck in the infinite bootloop. It was as if everytime it tries to boot up, it crashed during it. If I hit the power, vol up, and vol down button, I make it to the screen with the option to go into recovery, download, etc. But when I actually try to go into either bootloader, recovery, or download mode from that menu, it crashes and goes back to the white htc logo. I've have gotten the phone to bootup a couple times by leaving it in the freezer as it tries to boot up but after using it for 1-5 minutes, it crashes again. If I don't use the phone at all, then it usually wont crash. After a day or 2, the phone fixed itself. Then one morning, my notifications got stuck together and my screen became unresponsive. So I took my death sentence and restarted my phone and now my phone has been doing the same exact thing for a week. I don't know how to fix this problem because getting it crashes trying to go into recovery and trying to do a factory reset is risky since it could crash during the reset. If also manage to make it into safe mode thinking maybe an application or virus is causing this but the phone crashed in SAFE MODE so I don't know what the problem is. I doubt there is any saving this phone because is probably a hard ware problem but who knows. Any help would be greatly appreciated!! Thank you.
Flash back to stock. Stock firmware fixes all sorts of issues.

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.
