Well, I went to Samsung's service center for repairs, they gave me an estimation of 8.3k INR. According to them my pcb is damaged and they need to replace it. Why would I give them for repairs if I can get a used 16Gig oHD for 9k!
Also when I got my phone back all my black screws were replaced by cheap steel screws
Thankfully nothing from the inner hardware was stolen. Usually that is what they do here if you refuse to repair!
