If the "i" attribute is set as you show with the lsattr listing, then 
even root is not suppose to be able to modify the file. You may not 
change it or remove it.


Re-check that the "i" is still set, and then try to modify the file with 
an editor. You should not be able to do so.


Or, try to remove it.


Let me know what happens.
