HT1339 Restoring iPod nano to factory settings failed. The device switched to black screen immediately and is dead since then. Any idea what I can do now?

Question

This week, my iPod nano suddenly seemed to have lost all the music that was on it.
when connecting to iTunes, it showed that the music was still there.
I tries to create a new playlist with 1 song in it and according to iTunes, that was successfull.
the iPod however still said 0 numbers are available in the music list.
finally, i executed the restore factory settings and that process failed.
the device immediately switched to blank screen and is dead since then.
when I connect the iPod to the computer, the computer detects that a device is connected and even recognizes it as an iPod.
however, the device is not visisble in the windows explorer.
iTunes automatically starts but shows the error message: the connected iPod cannot be identified ... unrecognized error (2005).
Does someone have an idea what I can do to make the iPod work again?
thanks!

Answer 1

I tried by connecting to another available PC.
I newly installed iTunes on a PC that did not have the installation.
Connecting the iPod to this PC gave following error: "The iPod software update server could not be contacted. The server does not support this version of iTunes."
I followed the instructions in the "more information" section: iTunes version is the latest available; operating system version is up-to-date, no security obstructions and I rebooted my pc as suggested.
Next attempt to connect the iPod gave another error: "An iPod has been detected, but could not be identified properly. Please disconnect and reconnect the iPod, then try again. An unknown error occurred (2005)".
This is exactly the same error as on the first PC.
the iPod is still out of use
