Insyde bios editing tools not working

For a few weeks I’ve been trying to mod my bios to allow me to access all the hidden menus.
So far I’ve gotten to the point where I’m satisfied with the modifications that I’ve done but every time I’ve tried to save the files I keep getting the error “fail to write SCU string!”
I’m using the Insyde h2oeze tool.
My laptop is an acer aspire e5-575g with the intel core i3-6006u.
Any help would be nice :slight_smile:
