After installing Zune Software 4.0 the update of my Zune device (80GB) failed, prompting an error message:
Your player has encountered an error while trying to update to the latest software. Please try to update your player again.
Summary: An unknown error occured.
Error code: C00D11CD (80070057)
I already tried to reset my device and carried out all instructions I found on the web. Finally I performed a complete formatting of my device with an even worse result: I can't install any firmware anymore. When connecting to my PC the error message returns. I already tried to reinstall Zune Software after downloading the entire ZunePackage from Microsoft, following the instructions indicated here: http://support.microsoft.com/kb/945278/en-us/
No improvement, the error returns.
My Zune remains without any firmware.
Someone to help me???
