one more tipp for all the people that stuck on android boot screen
its easy to fix , run the kdz updater again as admin on windows 7 select the cs emergency mod then wait till your phone turns off and the batterie starts to load in 1 or 2 minutes your screen should tell you done.
then press volume down and home and power like if u would go to custom recovery then android is gonna restore the full package of the system then reboot your phone and it works again.
