ATV install after Seas0nPass

After insrtalling Seas0nPass when I install ATV flash black software it installs fine then the ATV screen goes blank. I think it restarts after ATV installation and then stops to work. Anyone has any ideas??

I think you need to tether boot the aTV after the aTV flash install.

After ATV install the aTV does not respond to DFU mode and is not responding.
