   How does it work?

   
   As you can see, there are several functions. Some of them work for all Xperias, some of them not. But there are two functions which work for every Xperia smartphone - firmware and kernel flashing.
   
    
   

   Something for the beginning:

   
   
   
   
   • downloaded .ftf files should be stored in flashtool folder . There's a folder called firmwares -> this is for .ftf files (C:Flashtoolfirmwares)
   
   
   • connect your Xperia only when flashtool wants it
   
   
   • ignore when flashtool says "Hold back button," buttons for connecting are specific for every smartphone (list below)
   
   
   • make a backup before flashing! Use MyPhoneExplorer, PC Companion, apps in your smartphone, whatever you want...
   
   
   • if flashtool didn't flashed selected firmware, remove battery from your Xperia for five minutes a insert it back. Next connect should be working
