Hey Albert, how did you resolve your problem?
I am in exactly the same situation - followed the video, upgraded the firware, NEBULA now is bricked.
I would be very grateful if you could let me know how you did it!
My name is Dirk and I am a documentary filmmaker from Berlin (also, I am in th middle of a project that I needed the Nebula for, which makes things a tiny bit more dramatic for me…)
My email is dvdb@outremerfilm.com
THANK YOU!!!
