Hi, I recently purchased a HTC Desire HD from Ebay. I found that I am unable to use HTC Hub on it. When I tried to install it online, I was asked to sign in throught google. When I signed in through gmail, there was some other problem, mentioning that google play store did not come installed with my mobile etc.etc., I dont know what to do.Even my seller is not responding.Other problems with the phone.. 1. Screen does not lock at all. 2. Personalize option in setting is non functional. whenever i click on personlaize, it goes to home screen. 3. HTC likes also does not open.. Can anyone help me on this. Thanks Praveen.
