how to Unlock a HTC 626’s Desire

Hi guys and gals. I’m new at this so i need your help please. last night i recieved my XTC 2 clip box and down loaded the software/program from the website but it keeps saying choose a "Drive" so i kept trying and my HTC went complete black. its fully charge not sure if i fried it which i doubt it, ill find out if its working or not later after work. can some one tell me what am i doing wrong? I appreciate your time and help.
