This is Based on a command line tool written by Bin4ry (Andreas Makris), I brought a customer interface to sin files installing.

SX Flashtool can also easily unlock the bootloader of your phone using the BLU icon as far as the bootloader of your phone is unlockable.
The flashing feature, as well as bootloader, unlock feature are available whatever the device is recognized or not by the application. What is only mandatory for installing is to own the FTF file according to the smartphone you want to flash it on.
