I have a Samsung Galaxy S2, running Android 2.3.
I have folder named usbStorage. After the firmware to latest version (via Kies), I can't see the usbStorage folder. When I mount the storage via USB mass storage mode, I can see that folder with all my content. I tried to copy some files in that folder, but no luck. When I connect the phone to MTP mode, I can see the folder but it's empty.
Is there a way to get back that folder? I can move all my content to another folder, but then I need to rewrite my applications that depend on that.
