Rooting guide for 4.0.4(locked bootloader) is available by doomlord...But one of the requirement says phone to be in USB Msc connection mode. my question is ,everyone says to select MSC mode in settings-xperia-connectivity.
But its not there in my phone!!simply no option at all!!
there is an option of mount usb in settings-storge,but that is always grayed out
wether connected or not
