error: boot guard verification failed
my original bios file I would appreciate if we can fix this problem pls
backup.rar (4.7 MB)
@isenturk - What did you do to BIOS to cause this to happen?
What is the above attached file? How did you create it (What software, or tools etc), and when did you make it (before/after this issue?) Do you have ANY backups made, using ANY method, before this happened?
I have not looked at file yet, need more info first
@Lost_N_BIOS
I took a backup with tl866 programmer.
bootguard verified error when opening the computer gives any error and closes itself when you press any key.
@isenturk - Thanks for answer to one of my questions 
What about the rest of my questions?
When did you make this backup (before/after this issue?)
Do you have ANY backups made, using ANY method, before this happened?
What did you do to BIOS to cause this to happen?
@Lost_N_BIOS thanks for your interest.
I just got the backup.
This process occurred during bios update.
I don’t have any backup before.
I cannot enter bios recovery mode with CTRL + ESC.
just dxe doesn’t write the rest the same error
@isenturk - You’re welcome! Thanks for answers. Please wait, I will fix BIOS for you 
Sorry, but I have to leave shortly, so I may not have time to do this until tonight (about 15+ hours from now) 
What BIOS were you on before, and what BIOS did you try to update to?
Also, please confirm, this is your BIOS download page, correct?

do not remember the previous version.
This error occurred while updating to the latest version.
Thanks, yes, same page I linked too. I understood what you meant about updating causes the issue. I see failed BIOS update in your attached file (not all BIOS modules in there, some corrupted etc)
I will fix tonight when I have more time, don’t worry
@ Lost_N_BIOS
The device worked great. You know this job. You are the man. 
I would appreciate it if you would share with me the tools and editing steps you used to correct this.
