This thread isn't dealing with the OC kernel specifics and issues its solely a guide for people to flash things through fastboot utilizing FlashTools. If your bootloader is locked you don't have access to fastboot.

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

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...

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
