weird bootloop broblem

Hey!
two days ago, out of the blue, by device restarted it self, and started to to it every few minutes.
after that, it just stuck in bootloop tho it was able to turn on for few minutes once or twice,
I tried to recover to factory settings from the phone, re flash the latest version with LG bridge, and use the flashing tool to reflash the kdz.
it always goes back to booploop(I think)
download mode works and not crushing.
any ideas? I

Unfortunately, the same thing's been happening to a lot of people lately. I'm getting bootloops on my G4 but it hasn't happened enough for it to be a problem. Once it becomes more of one, i'll send it in to LG under warranty. I would suggest you do the same too (LG warranty is 15 months from the month the phone was made - that info can found on the outside of the original box) Good luck!

Boot loop problem

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!

[Help] LG G4 H815P stuck on Firmware Update

Hi,
I tried to upgrade my LG G4 H815P with this thread:
https://forum.xda-developers.com/g4/development/h815-nougat-stock-locked-bootloader-t3709119
The process with LGUP was ok (upgrade mode), but after the first reboot the phone stucks on LG logo, so I tried to use refurbish mode but the process throws a error 0x2000.
I tried a lot of solutions but the problem continues.
Maybe you know a tot file with android 6 to restore my phone with LGUP?

Seems like the restore only works with H81520p_00_0314.kdz
Solved!

LG G4 stuck on Firmware Update (KDZ, TOT - Not working)

So, some time ago I finally gave up on LG providing official nougat update for LG G4 so I decided to flash it and I found an official flash v29a, and everything went well.. except for my GPS. The GPS was not locking on and would take more than 100 seconds sometimes to lock on, I did not had this issue before so I decided to flash my device again hoping it would fix it, but it bricked my phone.
Now I can't reinstall or downgrade, since it would get stuck at 16% when flashing again and downgrade wont work at all. I get error 0x2000 "Invalid command Response". I have been trying to fix it for more than 6 hours now, downloading different KDZ's but it just won't work. I really need help here, I cannot afford a new phone right now. I have LG H818p version. And yes, I was using the correct version for upgrade/downgrade. I tried to hard reset it but it is still stuck on Firmware update. Urgent help is needed, since I don't have another phone to use and I really need this phone, been up all night trying to fix it..
Edit: Fixed it, don't know how tho
