Hello Community,
Yesterday my G3 stucked in a Bootloop without changing anything. Than I wanted to repair it with the LG PC Suite. This failed with the message "Assert" multiple times. Now it stucks in the download mode. Can I repair it? More important are the files on the G3. Is there a way to get them?

Try this:
1) Remove battery
2) Hold down the power button for 30 seconds with the battery out
3) re-insert battery
4) Try turning it on again.
If that doesn't work, do a hard reset. You can find multiple posts on how to do it. Hope this helped!
Maybe I can help somebody with the same problem. I solved the problem with the following steps:
I setted up a new Windows 7 x64 PC. It must be Windows 7!!! No Windows 8 or other shiny things.
Installed the driver
Flashed a compleltely new firmware (.tot) over the old (!) FlashTool.
Hi guys. First, sorry my poor english. I'm Brazilian.
I make a firmware upgrade from LG PC Suite, 4.4 KK to 5.0 L. Problem is, the upgrade failed, and now my LG G3 are stuck in download mode. I try make this upgrade from LG Flash Tool but the problem persists, 65% appears in the screen of LG G3 a message "ASSERT" and reboot to download mode screen. Help, please?

Although I have never come across this, using this site to download the right KDZ and using this thread to flash that KDZ may solve your problems. There is no harm done in trying this and you can be sure that it is the right file.
LG G3 Boot problems after download mode
Hello!
Sorry revive the topic but it was the only one who found a similar problem, after searching lot on google.
I have a LG G3 D855P. Yesterday he went out and restarted many times, but worked for a short time.
I can use the BoardDiag, but when I restore the D855P20C_00.kdz .kdz, to reach 36%, the cell phone goes off and does not return. I need to take the battery cable, so that it returns to the download screen, but still, to get 36% he goes again. Have made sure that the .kdz file works properly.
I followed the tutorial presented in this video.

Hi !
I'm having a big problem right now. Few days ago, I tried to Root my phone everything was fine. The next day I wake up and go on my phone and there is a boot loop when I try to open it and it never ends. It's a loop at the LG life's good logo.
Few things I tried so far before coming here:
1) I tried all this :
http://forum.xda-developers.com/showthread.php?t=2785089
When I do it with LG Flashtool 2014 it goes to 4% then it stops/crash.
When I try with LGFlashTool I get : Model Information: Check FAIL! (but I put the good model in the files)
2) I tried a hard-reset but when I do the hard-reset it goes back right away to the Boot loop.
3) I tried with LG PC Suite, but the it says Mobile Device not found so I can't get it to repair with LG PC Suite.
I don't know what to do anymore.
My phone is a LG G3 D852 (Canadian)
Hopefully you guys can help me out here. Thanks a lot
Well apparently doing it on another computer fixed the problem!
hello guys i have a lg g3 d855 i flashed it with android M every thing worked fine until 2 days ago it started rebooting every time i turn on cellular network or wifi so i decided to reset it after the reset it stuck in bootloop so i decided to flash it with custom lolipop kdz with lg flashtool i got the right kdz and started the process, the lg flash tool didn't complete the process with device not connected error and my phone now stuck in download mode and every time i try to flash it , it take more than 1 hour to reach 4% on the phone and 16% on the lg mobile tool
hi. you were supposed to use LGup to downgrade. read this: http://forum.xda-developers.com/showthread.php?t=2785089
My phone was bricked hard and i had to us many tools to unbrick it and it worked and i have opened download mode band started lg flash tool but every time it reaches 100 the screen goes black and lg flash tool fails to flash and the g3 returns to 9008 again and i restart doing it from the beginning for about 7 times.
The problem is at the last time i have unbricked the device with a different .tot i guess and it did the bad thing.
My phone shows the lg logo of boot for a second and turns black. Then comes agin for a second and turns black.
And the sequence have going for about an hour
And the download mode do the same and its not opening even so i guess that the best way to solve the problem is to brick the phone again.
But this time its my choice to.
So i need help
I think you are flashing wrong tot.make sure the model of your mobile and then flash the exact tot.
My lg g4 H815 is not starting, after a sudden restart, it gets stuck in lg logo. I think its bootloop,isn't it?
Now which method should I try to make the phone workable?
Bdw, my os was 5.1, I there was no update and Bootloader was officially locked. While I tried to unlock,there was no alternative years ago .
Tried these method but not working
https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
also LGup tool not detcting device on PC (I assume it is occuring cause phone is not bootnig)
PS: Today 2-3 time was on but no sooner had I tried to nvigate,it again boots/ one time I unistalled 2-4apps and later its again boot)
Please suggest me what to do or follow?
