PC Studio recognizes my phone and connects it, but if I try to browse files (pressing B2100 sign on the right side of PC Studio), it says I should change pc connection mode from PC Studio --> Mass Storage on cellphone.
So I change, but it still displays this message. I've tried every way possible, e.g. relaunching PC studio if cellphone is already in mass storage mode, but no use - still suggesting to change it.

Any advice? Thank you!
