So..I have this d855 2gb 16gb variant.
It is rooted,it has cyanogenmod 13 nightly with kernel adiutor(with cpu governor set).It worked like a charm (3 months till the last update).
Today I launched youtube app and all of sudden it restarted..and it kept restarting in a bootloop.( he passes lg logo and enters the android one and after 10 15 sec it reboots.)
I tried to charge it,change batteries but with no luck.
I deleted dalvik cache and cache..but still nothing
then I tried to flash again the rom and there the phone gives me 35% of the times demigod:TZ crash with green screen.. and the other times demigod:Kernel crash.
I decided to delete kernel adiutor folders hoping for a luck..nein. ( using twrp)
I can access TWRP,it works fine but when flashing sometimes it gives me that demigod errors.
I can pass the LG logo but it gets stuck at android logo then restarts..or at finalizing/preparing apps.
baseband-modem: 21C
cm version: 13.0 2016 10 22
any help?
UPDATE:
Windows detects my phone as "LG Android Usb Device".
UPDATE2:
after leaving it resting one night it booted.
i still need help fixing it because it's not normal.
It worked fine from 6am till 1pm.
Now it freezes and restarts randomly.
need help guys..
Flash stock rom and test for crash couple days. If still crash, then if your G3 has still warranty to service. Probably MB broken.
If no crashing then root and flash rom

Unfortunately it gave me demigod: hw reset and no longer wants to load TWRP or download mode.
It restarts at the logo or at the android loading. I'll give a shot for the warranty.

Hey there,
I use a LGG4 international version (H815). It is rooted and runs AICP Rom (MM 6.0.1). Xposed is not installed. It runs latest SUPERXE kernel.
While browsing the web it randomly got a blackscreen and an error message (some kind of log whats happening) showed up. It said that the kernel crashed. Rebooting did nothing, even while it booted the same error screen shows up, but this time with a green background. I booted to twrp and wiped everything, reinstalled the kernel and the system. And again, the same green error screen. I tried again and i could actually use the rom (Latest Genesys rom) for some minutes, then i got a random reboot. Even twrp hanged itself up and/or rebooted. Now I dont have any system installed and cant boot to twrp because the green error screen (see attached pic) shows up after the twrp boot screen. Is my phone ****ed?
Oh, and my external SD somehow died, cant recover it from windows or any other phone. So maybe the storage of the phone itself is damaged too?
Please help!
Thanks in advance
Aicp =/= stock rom.

I know, that's why I switched back to a stock based rom. And I tried too with completely LG stock rom, same issue.
As of a few days ago, my LG H815 has random bootloops, like it will boot up fine, work for around 1-2 minutes, freeze, then reboot and bootloop, and then after a while it will reboot and boot fine again, but then freeze after 1-2 mins of use and so on...
Tried putting in download mode, LG bridge recognises it, says connected, then says device disconnected.
tried KDZ method and it starts fine, but stops arount 15% each time
cannot seem to get into TWRP or anything
device has MM on, with TWRP, imperium ROM v1.x and has an unlocked bootloader
I am in the UK and have the international H815 model

isnt this the famous bootloop issue.?
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
Hey I need some help with my LG G3. It keeps rebooting after the Boot has finished. It shows my lock screen for about 3 seconds and then restarts itself. You have any idea how to fix this? The Problem startet 2 days ago, when the batteries runs out. After reloading and starting it just keeps rebooting.
I´m on stock LG android 6 with no Root or custom recovery
What I have tried so far:
- Used other stock battery
- Tried Safe Mode
- Flashed Stock Rom again
Could it be the battery? Damaged by going too empty?
Thanks for your help...

When I had this problem before if was due to battery. The phone restarts itself no matter what rom I was on. Buying a new battery was the solution I found. But if you tried another battery and still getting this, it might not be the reason.
G3 D855---ROM : Crdroid 7.1
Testet a brand new battery. Problem is still there.
Is there a way to backup my data before a factory reset? just can get into download mode. Is it possible to flash a recovery system with the lg Flash tool?
After recovering from a previous bootloop issue with my Tab S, I'm in the same situation after flashing the official Samsung stock ROM for KitKat 4.4.2 via Odin.
When the ROM was first flashed, the tablet began working as per normal with the exception of it taking 10+ minutes to fully reboot and the device somehow restarting itself and loading the display within a second. However, after a few days, I kept receiving pop-up windows on the tablet stating that different applications (most of them I didn't have opened or running in the background at the time) weren't responding. A couple of days after that, more of said pop-up windows kept appearing on the screen, sometimes freezing the whole device until a push notification appeared in the background or the device force-rebooted itself.
I flashed the ROM again once or twice and cleared the cache partition to see if that made any difference, which it unfortunately didn't. I also removed the microSD card and SIM card, force-rebooting the device without them, and then with them when that test failed.
Now, for roughly about a week, the tablet has been stuck in a bootloop (the splash screen animation) where I have left it to drain the battery, leave it for about a day or so, and recharged it to 100%. So far there hasn't been any success.
Today I finally factory reset it to see if that may help, and the only thing that has changed is that the sound of the device rebooting is now playing when it does transition to the loading screen, which I had turned off previously when the tablet was still working.
Is there anything else that I may have missed that could help it work again? It's not rooted (and I would very much prefer to keep it that way) and has not had a custom ROM installed or flashed onto it. It can still enter Download Mode and Recovery Mode, but other than that and being about to use the Power-Volume Down technique, there's not much else I can do with it so far.

Factory reset, install stock firmware, wait ten minutes and you should be good.
But why kitkat? MM is available and working well.

It worked! Thank you so very much!
And I'm not a huge fan of updating my Android devices due to past experiences, but if this happens again, I might just update it to Marshmallow.

@ashyx
i love you man...this worked for me too...thank you...now i need to reinstall TWRP again and see what's cooking......
I had this problem recently too, with the added complexity that the "Factory Reset" option in recovery wasn't working -- it would say something like "MDM does not allow factory reset" and then just reboot.
Fixed it by directly flashing TWRP with heimdall, then booting into the new TWRP recovery, performing a factory reset, and then rebooting the OS. This time it got pass the bootloop.
i flashed new twrp for T700 it's bootloop cannot enter the twrp menu keep bootlooping ...what's the solution for this?please help
Help ME!
What are "stock firmware" and "MM"? and where to get it?
I've replaced the power button thinking it was a hardware issue but now I'm not sure. I've also installed a few different stock roms but still have the same problem. Does anyone have any insight as to what could be going wrong and what I can try to get it fixed? Thanks for any help you can give. The device is a Samsung SM T-800
