Cloud Search HTC Desire D816d Indian Version! Req stock firmware for asian version.

Hello devs,

This was my first time i bought a htc, so i need a little help from you guys,
can anyone link me the stock firmware of h&c desire 816d indian version, which is unrooted.
as i have to send my phone to warranty so need it ASAP.
Any help will be appreciated.

Thank you.

PS:I would be glad if someone provides me steps to flash the stock firmware, as i said i am new to htc.
