Okay, try this:
Connect your phone and first, flash it in 'Download Only' mode. (Make sure to select all the partitions (I mean the files))
Then flash them all again in 'Firmware Upgrade' mode..
I'd recommend you to flash the KitKat file.

Boot Verification Failed

Hey all, I really have no knowledge when it comes to phones, so any help would be appreciated.
I have been trying to root my LG G3 for a few days now, but it just wont happen. I have tried PurpleDrake and ioroot and end up with the same error every time whilst the phone is restarting. As the screen is black and attempts to boot, in the top right of the screen, the message "Verification boot failed! cause- MISMATCH_SIG_LEN" and then the phone will just go to a black screen while the LED alternates blue and red. This also happens when I try to enter stock recovery. I know I have the latest ADB drivers installed and the right drivers for my phone, so that can't be it. My G3 is a D852 with SV 30b on Marshmallow, my carrier is Bell. Thanks.

If you able to do that than you can flash your phone again.....for more clarify you have to install your phone software again to solve this issue also you cant flash v30b again right now you have to flash any other version to boot up your phone.

Ah, sorry for the confusion, but my phone starts just fine. I should have clarified in the original question that i can just hold the power button and volume down button and my phone will restart like nothing happened. Its only when root programs try to reboot into recovery and when I try to do it manually. Again, sorry about that

Look here you get more info
http://forum.xda-developers.com/lg-g3/general/lg-g3-d852-telus-koodo-marshmallow-t3348286

And that's where I get confused, because when I look up how to get twrp, I am told I need root first. I have temp rooted before and used flashify to try and flash a twrp but then on reboot I would get the error.

Thanks a lot for your help Anik! I can be really dumb sometimes and the fact that I can't think straight at the moment doesn't help. Seems like the main problem would be is that I was downloading Autorec of the play store, which is for lollipop. Should have seen that coming with the logo... Again, thanks!

you could do 2 things.. one download KDZ use LGUP flash it and see if it was software related or something went wrong at flash.. if it keeps doing it then it has the bootloop issue.. and need to be sent back for repair....can you provide your first 3 digits of your serial number...?

yes it is its pretty easy... . file is big though... download kdz for you variant.. what android you are using.? MM or were you on stock LP.?
well i think since your phone is from 2015 august. that bootloop was supposed to be fixed by then. but newer phone are still getting hit by the bootloop.. but be aware unlocking the bootloader voids warranty.. some been lucky that phone were repaired some were denied repair..

Its been unlocked for ages and running the cyanogen rom, this is what is now stuck but was running fine. lg website doesnt have the programme any more, will hunt for it. so this will work even though phone doesnt boot?

here are the links but i think you got the BOOTLOOP problem that many been affected..
NO ...... the only way for your phone to boot and gather all data is to flash a moddedKDZ.. but am not sure if it works on your variant..
if you have warranty send it back...but if they find out its unlocked they may deny repair.. you must pay for it...
this will make it boot but it will make it slow. as it disables the main cores...

Impossible flash any rom

Hi All
After a bootloop experience and ILAPO fix I managed to start the g4 disabling 2 big cores recovered everything almost, then I made the mistake to update it again.
The phone is stuck again and when in download mode if I try to flash a rom it stops at 12% rebooting Always. I think some partitions are messed up, do you suggest to erase partitions and reflash them from backupped ones? If yes which command?
I thank you in advance for your superb availability and kindness , you are a north pole for this community.
My LG is a G4 H818p , the ilapo rom was 20e, then updated into 20h stock, no mod, no unlock tried, the phone is recognised by lg flash and salt.
Thanks to anyone can help and I know steadfasterx will be one of most thanked for his experience.
Cheers guys

1) so you were successful on flashing these files?
2) you may try the ILAPO fix list from my signature but there is not many hope for your device in the current state. doesn't hurt to try anyways though

I managed to flash the file you linked, the phone rebooted, for few secs I saw the little android robot and then nothing blue led indicator blinking as when it boots and lg logo...but not constantly autoreboot as usual.
Any other idea? What if I format partitions and after I use salt to flash the backup? Is it something possible?

you cannot fix the ILAPO with software. Flashing the ILAPO files is just to extend the life not to let it live forever.
I guess the time of your mainboard is over. buy a new one or send it to trash or (as said) try the ILAPO fixes like hand dryer, oven etc..
