You can check this out.
Probably if you have access to custom recovery and you change the kernel could fix the security error.If not you could try to flash a stock firmware with flash tool and reroot your phone.

Surely you're not referring to the "Secure Boot Error"?
It happens for recovery access or affects the normal bootup too?
In both cases you have to put device in Download Mode and flash a "bumped" recovery (TWRP is highly preferable).
If the issue persists, you have to restore the stock rom with the LG Flash Tool 2014 by doing a "CSE flash" and lose all data.
If you not solve, your device is officially compromised and ****ed up.
The warranty won't guarantee assistance for broken phone with custom rom or recovery installed.
Hello xda members!
Yesterday i just bricked my G3 D855. I wanted to flash the v21a kdz firmware on my device with LG Flash Tool but unfortunately i disconnected the USB cable from the phone while flashing. After when i tried to boot my phone i got this message at the LG logo: "Secure Booting Error! Cause: boot certification verify."
I searched on google and i found a program called BoardDiag 2.99a.
I followed the instructions in this thread http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 and after i got my phone boot into Download mode. I just flashed the v21a kdz firmware succesfully with LG Flash tool, but every time when i turn on my phone, after the PIN code it gives me a WARNING: http://i.imgur.com/FWASnak.jpg and i don't know how to fix it. And in the Phone information -> Software version is changed to v21a-GLOBAL-COM.
I searched for my problem on xda but i didn't find any helpful thread.
I hope someone can help me here.
Thanks in advance!
Hi
I had this on my D855 Taiwan version. I had installed the Euro version of D20h and got the exact same warning although the phone worked ok but it disappeared when I installed D21a which was for Taiwan region. I downloaded an app "LG Phone From" which gives information regarding which is the latest stock Rom for the phone. It appears that the warning is because the Stock rom is for the wrong region.
