"Installation failed try using an alternate flash drive" on Apple TV 1G

Hello,

Recently purchased the atv flash update for Apple tv 1g, tried installing but “installation failed try using an alternate flash drive” keeps appearing.

Tried 3 different USBs, even tried one usb on a friends appletv and it worked with him.

My apple tv is up-to-date (Version 3.02).

 

Thank you in advance
