Before changing any file permissions please follow the suggestions.
If there comes a time when something goes wrong on ur rooted device and u need to reset some permissions of certain files please do the following if the shell on ur kernel supports it..(if it as bash)
in the terminal emulator type
ls -l filename
Where filename is the name of the desired file..
note down the permissions (start with either -/d or something...followed by three triplets of r(read),w(write),x(execute)
The first triplet denotes permissions for the owner of the file (root user)
the second denotes permissions for the group owner n the last one denotes the permissions for every user other than the owner and group owners...
The numbers corresponding to the permissions are
R W X octal number
0 0 0 0
0 0 1 1
0 1 0 2
0 1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
eg chmod 0777 filename
Will change the permissions of filename to read,write,execute for all types of users..
Once done,u can change the permissions back to what they were..
