go to ebay or amazon and order a new digitizer .....lcd...... and frame assembly ...... do not buy from china it takes too long to get !!! then go online to youtube and watch one of many cell phone break down videos on your particular device. It will take you step by step to switch out the assembly. If you are not familiar with cell phone repair then this will be the easiest way to fix. Make sure before you assemble you have to make sure you double check all conections ......screws...... wire lead runs....... and snap connects.
DO NOT ATTEMPT TO REPLACE THE GLASS ALONE IF YOU ARE NOT FAMILIAR WITH CELL PHONE REPAIR !!
It is way too easy to damage lcd ......warp the frame ...... and waste a lot of time and money !!
