Boot image verify failed! please help

Hi,
I have a Huawei G6-u10 device which wont' boot and I get this message every time phone reboots:
"Boot image verify failed! "

I downloaded the firmware from official site and tried to apply update in recovery mode but it says : " an error accoured ...."

I tried to apply boot.img from official firmware in fastboot mode but it says Command not allowed. What should I do? Please help.

I tried to get the unlock code for unlocking bootloader but because the phone won't boot i can't get product ID.

Thanks

Android Pay Unable To Verify; Stock 6.0, Nonrooted, Bootloader Locked

So I loaded up TWRP and Despair Kernel yesterday and rooted my N6 yesterday. There's not much going on yet as far as I understand because Xposed still isn't ready for Marshmallow and the new OS has a lot of great features I don't feel like I really need root, unless for adblocking. Anyways, so I refreshed back to stock through Fastboot, however now Android Pay states it cannot verify the system as if I was still rooted, which I am not. Has anyone experienced this?
Is it possible that the system partition is still R/W? I looked for a way to wipe the device completely and start back up from scratch, meaning erasing partitions, recreating them, etc. but could not find any information on it. Any help would be great as I have a horrible memory and constantly forget my wallet, so Android pay would do a great deal of good as far as I am concerned. Thanks guys.

Bricked LG G2 (D803) Boot certification verify error

Cause:
-This morning LG released not an OTA update for my G2, me thinking "I might finally get lollipop" I just blindly said accepted. Without thinking about my phone being rooted and such. My phone started to restart then shut off.

What happens:
-When I try to restart it the phone it will turn on show the LG logo, then show "Error: Boot certification verify" and "Secure booting Error!" after that the screen will go black, but not off and stay there until I try to restart again, and the cycle will repeat.

My phone info:
-LG G2 D803
-Rooted
-No recovery (becuase when I tried to get it the "boot cerifaction verify will show up, but the phone would still restart as if nothing happened.)
-I have many xposed modules installed
-Launcher over stock LG software

What I have tried:
1. I have tried plugging my phone in to see if will be recognized by my computer, so I could reinstall the stock software or update;
My computer can't recognize my phone, so most of the solutions that have worked for others won't work for me.
2. I have tried Power+ Volume Down to get to factory reset;
The menu will show up but when I select it, it will attempt to restart but the Error: Boot certification verify error will show and it's "What Happens" all over again.
3. I have updated all the drivers necessary;
Won't work because of 1. reasons

What can be done?
1. I don't know how/if I can get into download mode. If that is one thing I haven't tried
2. I'll try letting the phone die as a last resort to see if that can help change anything

Honestly I have no idea. My phone might just be too far gone. Any new ideas or recommendations would be much appreciated.

-Thanks in Advance!
