Before flashing a new rom get to know a few things first... Go through the thread of the developer who has uploaded the rom, you should know about installation procedure (which is very important) so that you don't end up with a costly paper weight and the features which are available/not working on the new rom. Then you may proceed with flashing a new rom.
