I have an atv2 current f/w. I jailbroke it, and installed Black as per the Youtube video. All prompts were seen and replicated along the process. Firecore button showed up. Logged into my iTunes account etc. All good until it went to sleep, now it will not wake up. sits there and just blinks with a black screen. I DID NOT UNPLUG THE POWER cable.
Have written Firecore, anyone else have a helpful guess as to what went wrong?
