Error Read only files for all users

Here my problem.

As a root i created a file, and added the content to the file. Now i want to make this file as read only file for all the user including root. Some how i need to protect this file from all users.I tried using the sticky bit. It works for directories. Do any one have idea how to implement without using sticky bit.

You can avoid accidental modification to the file.

rakeshawasthi is correct.

Here's the commands for your reference, since I have them.

This sets the file as "immutable":

Code:
chattr +i file

This unsets it:

Code:
chattr -i file
