i had the same.problem and I know how to figure it out!
ok.
first,after the secure booting error,the phone still stays on.
so,turn off the light in your room and you will see that the screen is on,but it shows black screen,
so hold power button for 45 seconds.after that hold volume up and connect the usb.
your phone should be in download mode!now flash kdz using lg flashtool!
if it fails,use the TOT method (there are file.compatible with d802, d801 and more)
let me know if you fixed it!
Lol that's stupid. Sorry, but there are easier way to flash in ubuntu bootloader partitions.. U'll dont lose your data and u'll recover rom. Laf, sbl1, aboot, boot etc.

Hello.
I recently sold this phone and went to factory reset. no problem. However, i forget i deleted the STOCK home app. THere is no launcher on the device so LG Setup Wizard simply crashes when finished setting it up. There is NO ADB since the setting has been erased. I need to re-enable it in settings but can't get that far since LG Setup Wizard keeps crashing..
I think i'm screwed.. what a stupid way to brick..
Device is: LG Optimus L9 P769 T-Mobile variant. Thanks guys!
you should be able to put your device on download/emergency mode and flash a kdz file with lg tool, you tried it?
if don't try yet, take out your battery, hold + volumen botton and put your battery again holding even + volumen key, and conect your to your computer, it must show the yellow screen with the legend download/emergency mode, and in your computer must be install the drivers, to exit the download/emergency mode just take out the battery or hold the power button, and for flash a kdz file, search a tuto, there are many, and many videos to make it easy . All this process let your device as new, all applications and configurations
I am aware of that mode but when attempting to flash that way before, after upgrading to jellybean, it would never flash for me. So I didn't even try it. I'll give it a shot though. I also was able to download one of the cwm backup zips posted in the other thread and extracted the system partition then created a .img image out of it and will try both your method and flashing that img file when I get home from work. Thank you for your post!

SOLUTION
Installed the ICS uboot.
Booted to SW Upgrade mode via plug USB, hold volume up button, place battery into device
Launched KDZ update tool and it connected and went smoothly!
If you have the JellyBean uboot, it won't connect in SW Upgrade mode if booted manually.

Please help me,what can i do?I have the Phone only since 2 two days,an i wouldnt lost it Unhappy
Sorry for my bad english
Can you still get into twrp? With the phone off hold power and vol down til LG logo comes up the release and press again after. Should take you to a menu, just hit yes. If it takes you to recovery just hit factory reset and it'll,take you to twrp. If so, I'd recommend putting a Rom onto an sd and flashing it. You'll lose everything but it's better then losing this beautiful phone

You obviously didnt read his post correctly. He stated that when he gets to the factory reset area which leads you to Recovery Mode/TWRP it shows the LG logo appears and nothing happens.
As for you my friend if you are able to somehow get into download mode with a button combination you have a chance at saving yourself by using a TOT or KDZ file to restore your phone to stock software. But i also have a question for you.........Why the hell would you allow an app to flash a recovery file that has nothing to do with BUMP'D? The Bump'd recovery for our phones is specific to our phones! You should never auto update any recovery unless stated its ok from the Bump'd developers, Which they never did or will because our TWRP Recoveries are different than any other phones because of the bump'd implementations with in them and the boot.img's. Sounds to me like you may have screwed up your partitions and/or boot stack. Your are better going on IRC and requesting the help of TheCubed/IOMonster and AutoPrime, but mark my words you will face some heavy criticism from members of the IRC channel when you explain this story to them. But they are always willing to help.
I dont know why i have done it,im new on Lg.Before i had an HTC there is so many other.I will aks that guys.I hope i can save my new phone.

Best regards.
Hi guys! Yesterday I decided to unlock the bootloader, flash recovery (twrp 2.8.6) and the cyanogen 11 nightly. Everything went good until I tried to install the gapps, I noticed that the physical shortcut to enter in recovery (after the turning off, of course) didn't worked: the phone restarted or boot up the rom, but I was able to enter in recovery from the advanced restart menu from the rom. Going into the info of the phone where it says kernel there was written "unknown" and no way to overclock. So I decided to reinstall the kernel (the cyanogen11extended) from twrp, everything went good except that I couldn't restart into recovery, it stuck on rebooting until shutdown. So I tought let's use fastboot to erase ad flash the recovery partition and the kernel, but it didn't do anything even if on the cmd said okey and finished in something about a second, but when i tried to enter in recovery I always get stucked on rebooting. So I tought"well if I have the system image I could flash it with fastboot and restore the stock kernel", so I erased the system partition and tried to flash the system.img and I get the message that it is too big for the destination device. Now I don't have a system installed tye hotkeys don't work and I'm stuck on LG screen logo.
There is a solution or do you suggest to send the device in warranty, instead?
Pull the battery and try to enter download mode.
Hi vagelis! You mean without the battery? The hotkey is vol up+power, right?
Edit: i tried without the battery pressing the vol up + power (also tried with vol down + power) and it doesn't work, on the screen I have an image which says to put the battery in, and holding the keys has as only result to reboot the phone showing the image... I guess there's no hope right?
Edit2: I entered download mode using the g2 method, now I have to downoad the kdz rom and the lg flash tool to unbrick, right? But where I can download it since the lg site for the firmware is apparently down?

Ok guys, I was able to unbrick entering in emergency mode e doing the flash tool stuff. The strange thing is that when I start the flash tool putting the file kdz and going forward in the next window, when I click on read phone info the program stops working, if I click directly on stuff then the lg mobile support tool is opened. Now when it starts to write on the phone, the tool says that an error occurred (something like "the server is offline) but on the phone it says the port com and start to download the rom. If I say ok to the error of the lg mobile support tool it stops the firmware update and stops the program, if I don't click ok the firmware update end is work unbricking the phone.
Now I noticed that with the stock rom from the version v10h until the last one towelroot is not working, so I downloaded the v10g germany version (since the italy version was offline) and flashed with the same procedure as I have done with the unbrick, so I could run towelroot and flash the twrp and the cyanogenmod11. Thank you so much for your time!!
The topic is quite old, but I've just solved that problem. You should just do it:
1) hold power and vol down till you see LG logo -- immediately release these buttons and
2) immediately hold power and vol up button to enter into factory reset menu.
Then click "yes" and next "yes", too.
That's all.
So I was trying to root my LG V10 today but now, my phone is at a continuous boot loop with a message on the top left corner saying "Boot verification Failed! cause: MISMATCH_SIG_LEN." I completely forgot to unlock the bootloader before starting this (don't know how I could forget it) so I feel like that is the main cause of why this is happening. I managed to flash the kdz file, TWRP file, and copy the SuperSU v2.76 file onto the SD card before the boot loop happened. Can someone help me please?

I also forgot to unlock BL first and same happened to me. However, download mode was accessible and flashing V20J tot on My H901 resolved the issue.

I don't think download mode is accessible for me. Whenever I hold the power button and up button down, it makes the message on the top left corner disappear but it reappears after a couple seconds.
When your phone is turned off,Try to plug it to a pc by holding volume down key.You will enter in download mode

Download mode should be accessible. Follow these and then flash stock KDZ / TOT:
Remove and reinsert battery. (Do not power on)
Press and hold ONLY volume up button and connect cell phone to pc via USB cable. You will be in download mode.
Hello dear all,
I have managed to brick my LG G5 like an Old Mill Brick.
My LG G5 (lg g5 h850 titan) does not boot. It comes with an error message as follows: Your device is corrupt. It cannot be trusted and will not boot.
What I already did to Unbrick:
Tried to unlock the OEM. No way from USB Debugging as I cannot go into OS.
Tried unlock the OEM from fastboot (remote: oem unlock is not allowed).
Tried to flash some things like (boot.img, system.img) even adb sideload stuff. Nothing works. I cannot flash anything because (flashing not allowed) because OEM is not unlocked, but cannot unlock the OEM because it is not allowed. WHAT in the brick do I have to do now?
Cause of the brick of the bricks:
The LG G5 was on LineageOS, all stable and solid. When a prompt appeared telling me that I have to update the OS. So I was like yeah ok whatever. BUT, it did from OTA. I also had a specific LineageOS APP for updating the OS. After some minutes (updating) I immediately panic and started worrying. BECAUSE, I knew what time it was (my device is dead). I wanted to turn my phone off but it was already in Recovery (TWRP). So I just hit cancel. BUT after booting up the LG G5 that corrupt device error appeared and I cannot manage to get rid of it.
Please I need your help! I also watched and tried (2+ hours) to manage to solve this via Google and different links and Unbrick guides but nothing happens. I cannot unlock the OEM because it is not allowed. I cannot flash anystuff because the OEM is not unlocked.
Update: So, there is no Recovery System present. No stock Recovery, No TWRP. And I think no OS either. So only thing that is present is the bootloader screen smh.
Can you still get to TWRP?

No If I hold the volume down button and Power and when the LG Logo appears I release the power off and press again nothing happens. It goes again into that error. I can go in bootloader but can't do anything with adb or fastboot.
I think TWRP is gone too :/
You should be able to get into download mode. Hold the volume up button with phone fully powered down. While you hold the volume up button insert the usb cable. Then you can flash the full system kdz with LGUP
