Can someone explain what the mount R/O and mount R/W do in root explorer? I know what it stands for Read only and Read Write but I question when you have to use this button? If I go to Root explorer now, the app shows I am in R/O mode on the root directory. I see this as being what I should see but I have seen cases where I can go into Root explorer and I am in R/W mode. When do you need to change the status? I have had cases where I connected the USB and mounted the sd card. While I am in the sd card on the PC, my phone unmounts itself - it has a notification for this. I cannot remount again without pulling the usb. I don't lose the ability to make changes though. I have also been trying to put a notification in the system/media/audio/notifications folder but I cannot get the file to paste into the folder. It gives me a message but I can't read it as it flashes off too fast. If I cut the file from the SD card to paste, it removes it from the SD card but I have not seen it in the system folder. I am not sure these items are related but I wanted to ask. What I am trying to do is get a "quiet" sound file to play when a notification sound is called for. Apparently the NoLed app wants a sound file from the system to play for Other accounts. If a sound plays from that folder, it triggers the visual notification on the screen. I need it to be quiet so I created a white noise file to be played when in "vibrate mode" using Quick Profiles. Thanks for any help with the mount questions. I just want to get a better understanding of what I am seeing.
