Like others here, a jailbroken ATV2 that I purchased developed the black screen boot loop. I couldn’t fix it so I used Seas0nPass to upgrade the firmware to 5.0.1 so I could have an untethered jailbreak, and started over.
I installed XBMC and add my favorite add-ons so I am back in business. But I am not sure about the other stuff that used to be on the old jailbreak. I purchased the unit jailbroken as an experiment. It had Infuse and Nito too as well as XBMC. Do I really need these? I can put them back if I do, but I don’t recall using anything except XBMC. Perhaps I am missing out on something?
