I unlocked bootloader in my SXS yesterday and installed OpenSEMC Beta 3. Everything looks fine but I can't connect to pc with usb cable in file transfer mode. I don't see it in My Computer. I can only use fastboot mode. Tried on other OSes on other computers- same thing. PC Comanion doesn't see it as well. Tell me what to do. My backups of stock rom are in CWM location but now is TWRP installed on my device. Help!
