Pls. Help needed immediately. I m in the middle of swapping the device using few video tutorial in which I tried to swap the phone storage(not internal) with a 32 GB SD card. In details I use root explorer & go through : system>etc>vold.fstab & made some changes which only alter my internal & external SD card storage(which I not wanted). So going through another tutorial I have replaced the vold.fstb file with the one I already downloaded from the web but unfortunately the file totally different & as a result my internal as well as external SD card are gone from my storage section. So device not detecting any of them. And result is no more camera , gallery or music. So pls. Help me immediately to solve this issue.
