I've moved on from this device, so I'm reaching into the depths of memory, but you can use moto-fastboot to push the boot.img of the stock kernel, you can get it from sbf.droid-developers.org. Just grab the firmware package for your particular model. I'm not sure if you can flash hashcodes kernel via the same method. I've honestly never flashed a kernel on this device, I've NEVER had the need. Best of luck.

thank you for the help!
in hashcode's roms,the kernel is in /etc/kexec..but I have no idea how I could swap the kernel!!simply swapping Kexec folder between cm10.1(that give me no reboot) and Kexec cm9(that reboots)made Cm9 unbootable..
