unable to root my n900 under 4.4.2 !! topic

hello,

I'm not able to root my n900 under the last firmware 4.4.2 using "CF-Auto-Root-ha3g-ha3gxx-smn900" ! Odin3 gives me a message "Failed" in red, and my n900 blocked, I was obliged to update the firmware with Odin3 to unblock it!

any idea ? is CF-Auto-Root-ha3g-ha3gxx-smn900 working with the last firmware 4.4.2 ?

thanks in advance.
