Stucked :(

Everytime I tried flashing boot.img it gets stuck no progress on Flashtool and when I disconnect ti gives error "Too Many Lines"

I have Downloaded CM10 : FXP148-cm-10-20121124-UNOFFICIAL-anzu ROM from FXP site and using the boot.img found in the same ZIP.

Can someone please help?

Note: I already have unlocked bootloader, when I try flashing this using Fastboot it gets stuck at sending boot.img prompt...

Thanks for the response Ganesh, there is not error, it just gets stuck, no progress after I select the correct boot.img and press ok

Update [SOLVED]:

I guess the boot.img in the build FXP148-cm-10-20121124-UNOFFICIAL-anzu was not proper.
I have downloaded the FXP146a-cm-10-20121111-UNOFFICIAL-nozomi build and flashed the boot.img it worked perfectly.

Thanks

    It can be used only on cm9 based roms and not on original sony firmware.
