casey_boy from xda has posted the steps to flash a new ROM or to debrand HTC 7 Mozart smartphone. The method was originally laid by theintelligent but consolidated properly by casey_boy.
You must need to remember that If you are debranding your device, you need to install 2 ROMs and not one.
We advice you to charge the smartphone completely before following the below steps. Do not proceed if it’s not being fully charged.
