Boot tethered not working


New on this forum, thanks for helping.

I’ve been using ATV2 and XBMC for more that a year, occasionally, I had to use boot tethered, but today is not working.

I click on booth tethered in Seas0nPass and do all my steps successfuly, then I plug my HDMI back in ATV2, it’s still blinking.

Yesterday, I was able to boot my ATV but then still couldn’t log in XBMC, it would always return to main screen.

Any idea what is the heck is going on here?
