From my own experience I can say,
First of all clear all your outstandings in US$, if you have any pending transaction count that and make payment according to that too in advance. (TRUST ME you dont wanna go thru all I have gone, my account was about to get suspended. Well its long story, so Imma pass on it for now)
Then go to ebay.com, at the botoom find Legal and More. Click it and then look for Tools and Apps. In that section find Sitemap and click on it.
Under My Account click on
Change your country to India.
Than again on SiteMap,
Under My Selling Account click on
Change it to Indian Rupee.
If any how you fail, just email to RVISHWAKARMA@EBAY.COM
He is the guy who sorted out my problem by changing my currency to INR from US$
