Dear all, My apple tv story; Bought one year ago a hacked ATV. Really happy with it. Working over network + XBMC. I had it off for around a month or so. Put it back on yesterday and I got XBMC error that froze the ATV. Reboot did not work this time and after long waiting I got the error. I get a blinking question mark . When I boot from usb (patchstick) I get errors that is unable to mount sd3, so when I try to boot with HD, same results. I got HD into my imac and see partitions from HD. I am not sure what to do at this point? is there anyway to do a complete reset of the ATV?? Thank you very much for your help.
