1. I have done factory reset well before i have done flashing, but it didnt work at all.
2. I have cleaned the cache as well but that too didnt work.
3. Then i tried searching the flashing techniques. And i tried all versions (MY version was L104) L113 L116 L120 as suggested but none worked.
4. After flashing the mobile seems to be the same it doesnt boot at all. When i power it on using power button the mobile starts and shows " KARBONN SMART" which is the initial screen or startup screen which shows on the mobile and after that it doesnt move ahead at all. Stays there itself.
5. I did formatting and it was also OK with a green box didnt do flashing as suggested and switched on the mobile it was the same as said in the point no.4
6. A point regarding HOW MANY ROM's WERE USED was asked i dont know what exactly it is.
7. I would request you all expertise to give me a solution to my issue, unable to figure it out what the issue is. I have not installed any new APP before this has happened. It worked absolutely fine the before night next day morning it was switched off .. thought no power .. so plugged it into power socket and after few minutes switched it on and after sometime came and saw it was the same as said in point no.4
