Hi James,
I bought my ATV 2G around end of December 2010.
The Seas0npass worked absolutely fine - got the message "Tethered boot complete! It is now safe to disconnect USB".
After removed the micro-USB and connected the HDMI cable to start Apple TV on my TV with the intention to install aTV Flash (black) app.
However, when Apple TV started on the TV, there was no 'In Theaters' option under 'Movies' which is pre-install checklist in the installation guide http://support.firecore.com/entries/346673-installing-atv-flash-black.
For information, after finishing Seas0npass and connecting the ATV to the TV, the current software version is 4.1.1, Software build is 1553 and OS Build Version is 4.2.1 (8C154).
Please help me out with this one. Thanks!!
Cheers,
