Ccit A170W Flash File | Firmware | Stock Rom MT6572 [UPDATED]
Note: "boot.img" from combination firmware can be not compatible with current phone's firmware. In that case phone will freeze on logo, or will be rebooting after writing of such boot. To restore the phone to its initial condition you need to reflash it with different full stock (original) firmware (or try to write only boot of such firmware).
