I'm trying to edit the Enterprise Home screen to remove a few default application on it. I exported the file and copied it to my PC. I made my changes and saved it back to the same location it exported to. Seems it doesn't read the modified XML because it is not stored in the internal memory but the SD card. I'm unable to move it to the internal file system because it is read only. How can I change the file so it reflex my changes. Do I need to root my device to have access to the internal file system?
