After lot of research, I finally came up with a guide to unbrick Samsung Dart T499 which is soft bricked i.e able to get into the downloading mode. Here are some simple steps to do so :-
1. Download the required firmware ROM of Samsung Dart T499 from sammobile.com (After registration) depending on your Country/Region.

2. Download the ODIN V4.38 and the required TASS.ops file from here and Extract it. Odin_v4.38_itcse.com
3. Install the latest version of Kies or the Samsung USB drivers so that your phone can be detected once connected to the PC.
4. Open ODIN V4.38 and select OPS and browse the TASS_V1.0.ops. (After you browse TASS_V1.0.ops ODIN will show “Odin Multi Downloader GT-S5570“, this is perfectly normal).
5. Check One Package check box.
6. Click on One Package button and browse the ROM that you downloaded from sammobile.com .
