Title says it all. I have my aTV2 running an older firmware, jailbroken of course. I'm using it mainly for PLEX as I just stream my video files from my iMac. I want to update using Seas0nPass and possibly add aTV Flash (black) but I don't want to lose PLEX functionality which I know the latest firmware doesn't support. Any idea if is still signing 4.3? If not, would anyone suggest another route? Thanks in advance.
