Just received my console back from germany after getting the RROD. It works 
Until.... i plug in my hard drive, then I get 1 red light. I cant update the console unless I have a memory unit attached (the hard drive) which makes it impossible to sign in, or do anything.
What are my options....
Help please, its driving me batty
