Hey, all.
I have a D855 variant called D855AR distributed only in Argentina. When I try to dd any recovery image for D855 other than the stock one, I invariably get a boot certification verify error when I try to boot into it. I've already tried just about everything I can find by just google. Most troubleshooting for this error revolves around getting the device to boot normally, but I have no problem doing that. My problem is that I can't boot the recovery image I want, in order to install LineageOS.
Does anyone know what I might be missing?
Thanks.

Hi,
I want to flash my device to Android 4.4.4 Stock Android(Who likes this annoying LG Bloatware?).
When i wanted to get into Recovery Mode using TWRP the LG Logo pops up and in the top-right corner stands:
"secure booting error cause boot certification verify".
I tried everything i know to get into recovery mode, but nothing helped.
Go through the "first time" recovery manual installation procedure found in the CWM thread for the v500. I'm assuming you have a v500.
I have this problem too. Lg gpad 8.3 vk 810

Thanks a million, after hours trying every single method I found across the Web, this was the only thing that managed to get TWRP 2.8 on my v50020d 4.4.2.
It would be interesting though for us to let us know what exactly is that, because I found many people with the same problem than me, and this appears to be the only solution

Did It Bypass Ur Bootloader?

Well, my problem it was I was using this method (the only one which do not gave me any explicit error) to install TWRP, and when rebooting to recovery it was always loading the stock recovery. That app solved me that instantaneously.
I was a little scared to see first the message "secure booting error, device unlock, so boot success" but it did loaded after TWRP. I guess that is supposed to be that way.
Yep @Maxxd01 That "secure booting error, device unlock, so boot success" it means it bypass ur bootloader to boot into custom recovery

Good to know
Hi guys,
I really don't know what to do right now. I ran the BlissPop ROM (Lollipop) for some time and decided today to switch to Fulmics ROM (Marshmallow).
Before flashing the new ROM I wanted to update the TWRP and downloaded the twrp-3.0.0-0-d855.img . I got into Recovery Mode, Install, Image and installed the newer version. After that I hit reboot into recovery but I just got the error "Fastboot mode started".
So I followed this guide. The "shorter" version didn't change anything, so I erased all 9 Files and flashed them one by one as shown in the thread. But instead of fixing my "fastboot problem" I now can't even boot my ROM.
Instead, it just says
Code:
ERROR: boot certification verify
Secure booting error!
Cause: boot certification verify
The screen goes black and the LED blinks blue and red.
What can I do? All I wanted was to update the TWRP
If you can't restart your phone ( i mean going to system ) use download mode and go back to stock using TOTs method (i think when you flashed your TWRP.img you did it and you chosed boot.img so that's the problem)

follow this thread , i hope you find a solution for this . Good luck
Thanks, I followed a slightly different guide (this one), because somehow the linked FlashTool in the xda thread didn't worked proberly for me.
Hi everyone, I've spent the entire weekend trying to get my head around fixing this one...
My lg g3 was rooted with kingroot, i found an app called super sume which said it could switch king root to su... something went wrong on installation and when its booted up the phone wouldn't get a signal or even access the home screen. I've attempted flashing, recovery mode and download mode and each of them give me the dreaded error message "Secure Booting Error! Cause: boot certification verify" in the top left hand corner of my screen. Nothing seems to work any help would be appreciated. thanks

Are you able to enter download mode?
If you enter download mod, can flash a kdz and. Also flash a different kdz file. For example if you are on 30b flash 30c...if you have twrp recovery flash sharpening mod.zip file from recovery

HI i wasn't but i've just come across ImageprepGUI which has now let me start flashing again, just hope this works out. thanks anyway
Hi all and thanks in advance, I appreciate your help a lot!
I've got a V500 with Android 5 and tried to install TWRP on it.
The phone was rooted already, but the TWRP apk app did not work, telling "flashing failed".
I then used the dd method getting root in adb shell, and flashed TWRP 3.1.
Unfortunately TWRP recovery does not boot with the following message:
Secure booting Error!
Cause : boot certification verify
I guess, this is due to the locked bootloader. I could not unlock, as adb reboot bootloader
boots through to the regular UI.
Now additionally to this problem I got a soft UI boot loop. After showing the swirling LG animation,
it boots to UI, shows the desktop, and loops to the LG animation again.
I still can reliably use adb, and be root on the device.
Could you, please, help me flash TWRP right in this situation?
You could try installing v500-20F bootloader and twrp 3.1 with root adb. Check this links:

SOLVED!
So, after just giving up and moving on to another project of trying to flash the ARTX Kernel which didn't work (I'll update this if I find out why it's not working; my phone restarts when im flashing the zip and "2013-2015 [somename ] amurlle.com" pops up in log.) so I researched and found a zip called MrBump.zip which bumps your boot image to get rid of the secure boot check.
How to
Flash SuperSu v2.82.zip via TWRP and then flash MrBump.zip, the phone will reboot after flashing MrBump and then another time for finishing the SuperSu installation.
History
\\
So, I have recently updated from Cyanogenmod 13 to Lineage OS 14.1 as it's faster, pretty, and Xposed was recently released for Nougat.
Installing Lineage wasn't a problem nor Gapps or the su add on package from Lineage which unlocks the OS's own su management service.
I wanted to use SuperSu as it pretty, customization, and better privilege management compared to the option lagging 'Privacy Guard' Lineage uses.
So, I flashed the SuperSu v2.82 zip which gave me a "Secure Boot Error" when rebooting into the system. No partitions seemed to be corrupted or damaged but I assumed
it had to do with the boot.img file as I saw supersu patch the boot image for some stuff I don't know. I decided to research and get my team of arduino super AI's to find
something of an answer of how to fix my problem, stumbling upon an article on XDA from chainfire of a boot image signer. I used Cywgin to create an rsa key and signed my boot image
then figuring out I could use the "BootSigner.zip" to sign the boot image without me creating a rsa key, flashing the zip nothing changed just some other error of where it couldn't read
boot image or the boot image was misdirecting to the system. I then tried fastbooting the signed boot image I made, it didn't work giving me some other ****ty error of mutiny.
I then fastbooted the orginal unsigned boot image I took from my ROM which worked but when booting into the OS SuperSu was still not the active su manager.
I then gave up and am now writing this post in a last option of getting SuperSu on my phone.
I have tried SuperSu 2.78 and kingoroot from the PC hoping that I could then use SuperSuMe

Details of my device

1 second after turning on the phone the error pops up (the LG logo is visible when the log is onscreen):
ERROR : boot certification verify

2 seconds later the screen blanks and the LED on my phone blinks blue and red at half second intervals.
Any help would be appreciated, if you need any specifics of my device or screenshots just ask (I can replicate my problems and steps iv'e done if you need me to.)
Eureka!
I did the exact same thing and all the guides that I found assumed that you still had access to the system or had already wiped out download mode. There is a lot of advice out there that really just doesn't work. Anyway, I gave up and decided to do a wipe with suprising results.
boot to stock recovery by holding power+volume down
perform factory reset
phone reboots to TWRP - WHY?!?! I have no idea, but it worked
reinstall your latest lineage image from /data/data/org.lineageos.updater/app_updates/
wipe davlik/cache + reboot
profit!
I don't know why this worked and I stumbled upon this by accident.
Mileage may vary, so please share your results.

What?
You must've flashed TWRP before, and I don't understand what you mean here. Did you brick your phone trying to flash SuperSu too?
But i'm glad it worked out for you
Bump!

Yeah, I had TWRP on it before and got to that point by trying to flash SuperSU on an already installed copy of Lineage. I was really trying to revert to stock and start over when TWRP came up.
