I have a Karbonn Titanium Wind W4 running Windows 8.1 .I have developer unlocked the phone. I checked for windows 10 update using the Upgrade Advisor app but I was not so lucky to find one. I want to install the developer preview of windows 10 but I found that there is no warranty recovered after installing the preview. Please help me to do so. Thanks....
