Some more findings. I did JB my aTV in three different ways (restoring to original firmware in between):
- Seas0npass 0.7.5, plus XBMC, NitoTV - HDMI mode switching doesn't work
- pwnagetool 4.3.2, no additional apps (even NitoTV was missing) - HDMI mode switching doesn't work
- sn0wbreeze 2.6.1 (NitoTV added by the tool, no extra apps) - HDMI mode switching doesn't work
I will really appreciate some feedback.
Have to assume you are using the latest version of Apple TV 2 software when you restore between. Thats all good news on that. Where did you get the IPSW file to use with SNOWBREEZE initially? Just FYI that NitoTV can add apps within itself, I think.
