On a side note how did fib change the apple ID if phone was locked?

That's what I am asking. There are only two ways.

1. The iPhone 5C was unlocked and had no passcode when they seized it, they changed the AppleID, then they added a passcode and locked it.
2. The iPhone 5c was locked when they seized it, but they found a sticky note on the refrigerator in the terrorist's apartment saying "Allah Akbar: Passcode to my iPhone 5C: 1234", opened the iPhone 5C, synced everything on it to an FBI computer, found the AppleID, changed the AppleID, changed the passcode, then re-locked it.

So, after that, the FBI and DOJ, did more:

1. Called Apple and said "We need help getting into this iPhone you evil SOBs made too secure to get into just to support nasty child molesting perverts, terrorists, and other evil miscreants, come write us a universal backdoor or else!"
2. When Apple said no, we won't write you a universal back door, the DOJ went to a compliant judge who, using the All Writs Act of 1789, ordered Apple to cooperate and write a universal backdoor, or else.

On a side note how did fbi change the apple ID if phone was locked?

The FBI didn't. The San Bernardino County Department of Public Health did.

The Apple ID is distinct from the passcode on the phone. Many phones can be associated with the same Apple ID. The same Apple ID can be used with a Mac, iTunes on Windows, and iPad, or a web browser.

For the phone to back up to iCloud, it needs the Apple ID and password. Since the county changed the password, the phone couldn't connect to do a backup.
