worst service center.......i have ever seen. no proper response and false troubleshooting with false suggestion. Here my story, I went to service center with my HTC HD2 with error "reflashe proper ROM code" means ROM version what ever I was tried to install is not correct one. After 2 days they said, it is problem with mother board and have to replace which cost around 10k rupees. I am not a fool to spend 10k on 2yr old phone. so i took back my mobile and searched on internet found proper ROM code and installed. Now it is working normally.............these people do not have proper knowledge on some phones.
