@arp: It's hard to believe that you're really serious and not just trolling. If you cared to check more threads on this forum, I think you'd be awestruck by just how many helpful answers the target of you attack is posting almost daily - often in response to trivial, repeat questions from non-technical users like yourself.
But I guess frustration can make us all do stupid things.
Since you don't post details of your problem, I cannot help you there - as others already said.
I can tell you, though, that the steps posted by Jerry and jcase DO work perfectly. I ran the VMU update, not once, but FOUR times (I am testing some problems). Each time I rooted by simply copy-pasting the commands in the OP. The first time, there was a tiny mistake in one of the commands (adb missing), but Jerry promptly fixed that.
You ask if somebody found a better method for the technically challenged: well, a week ago (at least), brotherswing posted a separate thread with that exact title - using jcase & Jerry's steps, but packing them in an EVEN simpler form. I don't know how you could've missed that. It's in this same forum.
Good luck to you. With your phone as well as your social interaction in your life.
