You don't need to flash your bootloader since you already have the updated one. That's why it won't let you update (again). From your post 552 above we can see that you've also already unlocked the device. So you can move on to step 4 to root it now. If the Supertool isn't working, follow the link in the post below \/\/\/
CafeKampuchia- using your guide with supertool i get this:
it says that device is rooted.
Boot your phone normally, and the Superuser app should be installed. If it is, install ROM manager from Play store and if all is well, a pop up should appear asking if root privileges should be given to ROM manager. If that comes up, you're good to go.
There is no superuser, and rom manager wants me to root my phone.
As i said before i am not able to install recovery. Also on installing clockworkmod
