"fearless" If you take out the two screws under the dock connector remove the back and disconnect the battery then reconnect it your Zune 30 will work again. Frankly this is unforgivable Microsoft. I am thinking of selling mine and getting a Cowon player instead.
If you do this u will risk that microsoft will do nothing if we need to send it back in. Also THIS IS ONLY TEMPORARY once synced back up to a computer it will brick again.
