Can't get ATV into DFU mode when tethered

I got the AppleTV jailbroken after a few tries. Then I bring it to the power cord, run the Boot Tethered function in SeasOnPass, plug in the power and micro USB cords and press the play and menu buttons for 7 seconds.

SeasOnPass can't find the unit in DFU mode.

Any ideas?

Thanks in advance.

Did you ever get this to work?  I am having the same problem.  It seemed to jailbreak okay but I can't seem to get it into DFU mode.  

I think I figured this one out.  I was plugging in the power cord too quickly.  Need to wait until the ATV starts flashing rapidly (as stated).  Once I did that, it went into DFU mode after pressing the buttons for 7 seconds.

 

 

Same here, wait for it to go into DFU mode before you plug in the power cable.
