ATVflash seems to install just fine, but no Maintenance menu and no ATV flash features....

ATV is running 3.0.2, built new patchstick using ATVflash 4.4.1…  Install completed successfully and I was told to unplug stick and restart ATV… but upon restart it’s like nothing ever  happened.  WTF, over?

Your post does not sound at all like using ATV Flash (black) on the ATV2!

It sounds more like ATV Flash on the original sIlver variant of Apple TV. If that is is the case the this is thw wrong forum area.

Oops… sorry about that.  Please feel free to delete
