aTV2 – Jailbreak available, fireCore aTV Flash(black) updated…

Seas0nPass for iOS 5.1
Finally you now can update your aTV2 device to the new iOS 5 version 5.1 – Seas0nPass is available to jailbreak the device (tethered).
In addition fireCore has updated it’s aTV flash(black) software to get the well known software also on these updated devices now.
Seas0nPass for Mac [10.6 or later]
Seas0nPass for Windows [XP or later]
For the new aTV flash(black) version visit fireCore directly.
Update:
upgrading was not that easy at all – but worked.
I had to test it several times and it worked in the end by doing a normal upgrade to iOS 5.1 first and then the jailbreak with Seas0nPass. Timing after the jailbreak was also very important –> don’t forget to connect the device to the power cord BEFORE you remove the USB-cable and adding the HDMI-cable.
Short hint at the end: don’t expect the fireCore Logo after the jailbreak – it wasn’t there when I did it…
