how do i turn off firmware password from my phone since my macbook is disfuncional

What firmware password do you mean? For the iPhone or for your Mac? And is it the Mac drive encryption password or the login password?

If the Mac password, what was the result when you followed the instructions in the Related Article above your name on this page, that you were reading just before you posted here? If the Related Article doesn't answer your question please post back with more details about the issue and another user in this user-to-user forum will try to help. And if it is the Mac I can have your post moved to the Mac forum.
