I rooted my device. Then by gainng root access I renamed vold.fstab file and swapped sd card with usb storage. Then I installed chainfire 3d due to which my device has bricked. Its not getting booted up. USB Debugging is also turned off. And as my sd card and usb storage is swapped I cant install updates as they goes into internal memory of device. I dont know what to do. PLEASE HELP!!!
