Reset device failed.......... can't jailbreak

Hey guys, I can’t figure this out.

I’m running OS X 10.10.5 and Seas0npass 9.8. with an Apple TV 2 software 6.2.1

I just purchased new micro sd DATA cables, so I know that’s not the problem and seas0npass makes it to the bitter end and then fails EVERY TIME…

I’m just trying to jailbreak this thing and doing it without the power cord attached.

I appreciate any help you can give me!
