Thank you everyone.. The problem now has been resolved.
1. Initially, The USB connection wasn't getting detected,.. That's because i wasn't able to go to the download mode and always used to be welcomed with CWM Recovery Mode.
2. After trying so many things, the battery got depleted which created problems in reflashing the CWM to get rid of boot loop.
3. The Battery wasn't getting charged through Wall Socket charger initially and got it some how charged through CWM Mode for half an hour
4. Plugged the USB connection back and got into the Download Mode and then Voila ! the usb connection was detected and i reflashed it.. The Boot loop is no more there..
Thank you guys
