Update Update Update....
First I went to Ghatkopar at PC Clinic - it's very hard to find, little bit inside from main road, they do repair I saw many people coming there with items to repair.. but sadly they denied stating they can not resolder the the usb c port... I showed them videos on YouTube .. how they can do it with hot air gun and some solder... But it seemed their technician did not wanted to do it..
Later I went to lamington road.. and was enquiring at a shop at the ground floor of prime abgb .. and there a guy told me. They can do it.. on third floor they have a laptop repair shop .. room no 301.. there was this guy Aadil... He was young but very knowledgeable person and fixed it within 10 minutes ..
He saw the motherboard and came to know about history by just looking at it.. I was surprised.. but he fixed the problem..
Sharing if anyone interested
Offtopick...
There was a CPU reballing competition in china and one indian guy came third in competition...
It seems there are good technician...but not paid well or very hard to find...
Thanks for your contact..
You can try third floor of same building as prime abgb... There is a laptop repair shop.. they may can fix it
