@edgar: Thanks, truly regret and apologize if I was going too hard on you moderators. And obviously you do read the threads. I got a little irritated that peoples patience in here is tested with a lot of mindless threads causing noise, it seems like many create a thread first and then think afterwards.

I am going to help you out next time, using that report link instead.

@chubi: As for trying to be helpful, I'll do this once:
If you indeed have bought a completely new device, it is more than obvious it shouldn't behave like that. There should be plenty of room for you to install rootsh providing you did that right (even though it's difficult to do wrong).
I don't know why you don't see this but, either you have received an already used device in your box sold as new, or it is broken somehow.

You should return it to the reseller or wherever you bought it. It's as simple as that.
