Big Serios Booting Error

Hi Guys,
I'm trying to start my phone but i wont let me.... the error message: "Secure booting Error! Cause : boot certification verify".
I've tried the safe mode boot but the same happens here. HELP MY DEVICE CAN NOT BE TURND OFF I'm holding the key 'off' but the boot starts again with the same error message..... I have rooted my device and I can't send it back to LG due to the warrenty ... what can I do ???? :crying: :crying: :crying:

Well,so many cryouts AFTER messing up the phone.i guess you guys really deserve it because you are so damn lazy to read all infos necessary. It's been talked so many times i just can't count : ROOTING IS ONLY HALF OF THE PROBLEM. YOU NEED TO USE FREEGEE TO UNLOCK THE BOOTLOADER AND TO FLASH CWM RECOVERY.i just don't know why i bother answering.i think i'll just ignore future questions like this and will be focusing on real problems.

HELP !!Secure Booting Error! Cause: Boot certification verify

Hey there, im new in this rooting things and stuff and i want to install a room. So, I rooted my lg g3, and is working, but when im going to install recovery (twrp) or philz , I get the right IMG (bumped for lg g3 855) and when I run it at flashfy this error pops out "Secure Booting Error! Cause: Boot certification verify." The same happens if I do it trough TWRP mananger.
I downgraded the phone to my stock (that's what a guy at reddit told me to do because lollipop isnt alowed at twrp he said) so I followed the tutorial and it went back to my stock (Lollipop 5.0)
Tryied all over again twrp and philz. Both didn't work and the same error pops out.
Help pleeeeeease i don't know what to do
And sorry about my english, isn't my native language.
Thanks

Secure booting Error!

So I was trying to install TWRP on my freshly rooted V500 5.0 korean kdz, followed the steps exactly and I tried to reboot to recovery and got the
Secure booting Error!
Cause: boot certification verify
Reading through a few other threads, I tried going into download mode and upgrade recovery through the LG mobile support tool, but that says no items to upgrade. Now, my tablet will not boot up past the error screen and I'm having no luck finding any way to get it booting. Any ideas? Thank you in advance for any help!!
EDIT: KDZ back to 10a

Same here!

[Help] Boot TWRP Recovery Issue

Dear All,
Please be informed that I am unable to boot to TWRP Recovery and I am getting this error "Fastboot mode started udc_start ()" after I flashed Lineage ROM, so anyone know how to fix it.
Note, I am able to boot and load the ROM without any issues, but if I want to boot to TWRP Recovery I get the specified error message.
Thanks.

Guys .. Why there is no care about this thread?!
Thanks.

Guys .. Any support to fix this issue as it seems that I have stacked on this Lineage build forever.
Thanks.

It seems that no one wants to help in this issue?!

Unbricked my phone but now I'm stuck with the chinese firmware [BND-L21]

Hello,
I received my phone two weeks ago (BND-L21 version) and Friday I tried to manually update it to Oreo (with this topic : https://forum.xda-developers.com/honor-7x/how-to/manual-update-to-oreo-beta-emui-8-bnd-t3767044). I don't know what I did wrong but it didn't work (my phone didn't reboot on the stock recovery, only on TWRP). After a few try, my phone wasn't booting anymore, it was stuck on the orange message about the unlocked bootlader and the message "Your device is booting...".
I managed to get it back working with this topic : https://forum.xda-developers.com/honor-7x/development/firmware-updates-link-flash-risk-t3723810. The problem now is that I'm stuck with the chinese firmware (i don't have the Honor animation when my system is booting, I now have an Android logo on a black background). I don't have any Gapps installed and I can't flash anything with TWRP. When I try to flash SuperSU, i have an error extracting ramdisk failure and something with the boot.img.
Now the model of my phone is a generic_a15 and I don't know how to get back on track.
I'm a little bit desperate now, I don't know how to install another firmware. I tried to install this custom rom : https://forum.xda-developers.com/honor-7x/development/openkirin-aosp-8-0-honor-7x-t3746257 but I was stuck on the orange message again.
If anybody knows how to solve my problems, I'll be grateful
Thanks !
[UPDATE] I don't know if someone is reading but now my phone doesn't boot anymore and FRP is locked ?

Call Huawei customer support and get a ticket started to send your phone to the nearest repair center. Best of luck!
