I'm running SS 4.1, with a LV kernel, and was having a slight problem..
I can't reboot into recovery.
I tried the script in terminal and I tried powering on + x. The phone will stick to the M logo as long as I hold the x button, and as soon as I let go the M logo will flash and it will boot up like normal. When using the script it shows up as the M for a minute or so and then flashes and reboots like normal.
