ATVFlash 4.0.1 installation problems

[color=#0000BF]When I install the downloaded files on the USB drive, I see a message that it is successful for the Mac version.
After plugging in the USB drive and powering off the Apple TV, when rebooting, the USB drive blinks twice and the Apple TV boots up without seeing the USB drive and all I see is the Apple logo? :?: [/color]
