Everything was working fine gained superuser access after updating binary and also was able to run root applications, just 2 days later i tried to connect my device to my laptop running Windows 8.1, it shows:
"The last USB device you connected malfunctioned and windows cannot recognize it", so i restarted the phone but superuser access was lost as SU binary couldnt be installed.
Troubleshooting Already Done:
1- Restarted phone and Laptop
2- Re-installed drivers on laptop still couldn't recognize and also tried re-installing SU bin and superuser from CWM after disabling the superuser apk on-board.
3- Flashed the complete Rom once again from CWM but still laptop couldn't recognize neither root access gained.
