well this we come across on all threads, at some given point of time.

Reason being simple that we suggest some people to do as said below:

2) push the file XXXX to sytem/xxxx folder.
3) set permissions to rw-r--r-- blah blah blah.
4) reboot your phone and see.

Then comes the question again from the same people as below:

Hey,
1) I have done accordingly, but really confused regarding File permission though please explain?

2) How to set File Permission?

3) what is rw-r--r-- blah blah i cannot get it? etc.

So this Simple Guide will defenetly help the people with the same.

Let me not go in depth regarding the same,Since this excellent Tutorial from Matt Doyle explain's in more detail about it
Understanding File Permissions- by Matt Doyle

In order to set the file permission all you need is to have Root explore/Browser or similar type of File manager app been installed on your phone, with Root access.

when you open the File manager you see all your files and folder listed there, thats not our main concern, but something below each one of those file's or folder's, what we are really interested in like:

under say Data folder you see something like 'rwxrwx--x' which is of real concern here.

when you long press on the same Data Folder a pop appears as below

Fig 1

and when you select Permissions in that pop up menu it appears as below.

Fig 2

as you can see in the pic above the permission is set to 'rwxrwx--x' (771 according to Table below)

So in order to set the right Permission for a file, after you have copied the file to the relavent folder, all you have to follow is the below steps and also the Table guide below it.

1)Any File Manager app like Root Explorer/Browser,Es-file explorer installed with root access (Do ensure to Mount as R/W (Read/Write)).

2)Find the File which you have copied to the appropriate Folder for which you have to set Permissions with the above installed file manager app.

3) Long press on the file to open a pop up menu as shown in Fig 1 above.

4)Set Permission accordingly ( been suggested by people for you) using the table guide below as reference.

5) Then reboot your phone for the same (Permission set) to take effect.


Table Guide for Reference
----------------------------------

No- Box is Unchecked, Yes- Box Checked

So, for example:

777 is the same as rwxrwxrwx

755 is the same as rwxr-xr-x

666 is the same as rw-rw-rw- and so on.

I do hope this Guide will come in handy to all those people who want to set filepermission, but need some clarity upon the same.
