Hacking a Windows Phone 7 is usually a little bit harder than hacking most Android phones. Where most Android users have a whole development kit worth of tools to tap into—not to mention the various OEM tools such as Odin or RSD Lite—Windows Phone 7 users have fewer options at their disposal. In some cases, tried and tested methods may not even work. When they do, however, the burden is lifted for those who want to make their devices truly their own.
AT&T HTC Titan owners now have a guide pieced together by XDA Forum Member pbp8ntballer to help users debrand their devices and install HSPL (Hard Secondary Program Loader). The guide pulls information and methods from a variety of credited places and a number of XDA members and development teams.
To start, it is recommended that users downgrade their SPL before debranding the phone. In the words of pbp8ntballer:
*There is a possibility trying to debrand the phone without downgrading your SPL first may or may not work. When in doubt, it would be better to first flash this image first on your phone before proceeding any further. If your SPL is 1.10.xxxx.xx or lower, you may skip this process.
From there, users are to create a Gold Card, which is pretty standard for most Windows Phone 7 hacking. There are also instructions on how to create a Y-cable, as it is also required. Finally, once everything is said and done, users go through the process of enabling HSPL. From there, the sky is the limit.
Despite the simplicity of the step overviews, the process actually takes quite a bit of time. For additional information and a how-to video, check out the original thread.___________________
