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.

Hi,
dont panic, I went thru exactly the same process right up till the TWRP and wipe. All you need to do is get hold of the stock rooted rom zip from here:
Then copy it onto your sdcard, for which you can connect to the computer using Advanced menu of the TWRP, and load the sdcard, which will connect as USB storage to PC.
Then once file is on sd card, just go back to main TWRP meny and select install option, then select the zip file you just copied.
Let TWRP do its stuff, then do a factory reset / then go into reboot system.
Wish you all the best. Once the ROM has installed, now you can search for the latest TWRP, install it then go on to latest kit kat roms in exactly the same way.
milind
hope he follows up with a thank you.

That file is stock firmware inside the zip is a .tot file that can be renamed to .bin and used with lgnpst to bring the phone back to stock. You would need to be able to get into download mode
again. If you do use the g33k3r file you would need to root again then use Freegee app from play store to unlock bootloader and install recovery.

I guess this is original ATT LG E970 Firmware. I will copy it into my external Memory Card and then will insert into phone. After that using TWRP I'll be going to use this Zip file and after that factory reset. Am I correct ? Do I need to follow different steps ?
Let me know. Moreover do I need to unlock Phone again? When I received it was already in Unlocked State. So installing the above link firmware will lock it again? Or should I proceed with the link I posted earlier, I mean this ..

Please let me know.

make sure to download the first file too.... to get to download mode just use twrp's reboot menu... from what i remember it has a reboot to bootloader. From there you can use the volume keys to select Download mode and push the power button to go into it...

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.

Hypothetical question: say that I erased every single piece of data on the phone drivers system files operating system etc.. How would I put all the drivers and need information back onto the phone with access to only the SW upgrading mode?

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.
I am pretty new to this rooted community and i unfortunately felt a too confident with everyone saying it is really easy. I did a one click root on my lg g3 vs985 (35B version) and was successful. The next step was to install twrp and i attempted so with flashify and the latest twrp IMG. The recovery boot never worked and always did a normal boot. I resorted to this one tutorial which said to use an app called autorec. This where it went wrong. The reboot made my screen blank and none of the buttons did anything. I plugged it in and my laptop still recognized the phone. I pulled the battery and plugged in and the screen turned on (thankfully) and shows a missing battery screen. With the battery in i tried turning it on with the power and volume down button on and it vibrated. Now randomly vibrates. Please help i don't know what to do!
This forum is extremely unhelpful, but i managed to get it back to stock. I was missing some drivers and not being careful, i almost ended up with a brick.
What did you do to fix the issue? My phone is doing nearly the same thing though it was after installing JasmineROM that it occurred. The screen is blank unless I pull the battery and plug it in to see the missing battery icon.

1. Pull the battery and put it back in
2. Press and hold the volume up button and plug it in to a PC
3. Keep holding down the volume up until you see a screen which says download mode
4. Install a program called LG Flash Tool 2014 (Extract and put it into a directory you want)
5. Download the KDZ of the stock software you want (forum around here but I don't remember where)
6. Put the KDZ file into the LG Flash Tool folder
