What is this App:
This ROOT app is for mounting your memory card as a USB Mass Storage (UMS) device on your computer, or TV or Audio/DVD Player or whatever.
This app will NOT mount your Internal Storage (since it\'s located in /data partition inside the ./media/0/ directory and the /data partition is formatted as EXT4).
If you really want to mount your Internal Storage as UMS, it can done using the USB Sharer app (but it'll be mounted as read-only).
How To Use the App:
1. To enable Mass Storage, press 'Enable Mass Storage'.
(Try 2-3 times if it's not working, also try changing app settings)
2. Before disconnecting USB, eject from Computer first, then press the 'Disconnect Mass Storage' button.
Possible Reasons Why This App is Not Working:
1. Your device's kernel doesn't have Mass Storage Gadget with USB emulation support.
Solution: Ask any developer of your device to compile a kernel with USB Gadget.
2. Your device doesn't have memory card support, or there's no memory card inserted.
3. Your memory card might be encrypted or used as Internal Storage (for Android 6.0 and above, by which it is formatted as an EXT4 partition and encrypted)
Solution: Make sure it is formatted as a FAT32 partition.
4. There might be something (like Anti-Virus) which doesn't allow to disable SE Linux Enforcement.
5. Your device might not be rooted properly.
