A lot of tutorials, firmware and plugins for your nbox.

hi guys
whats this box like in general and for enigma 2 plugins

Its sh4 chipset, e2 has been modified to run with it. (probably why plugins are difficult to install, and flash is very limited as far as i can remember)
I had experience with one and used nebula image as per recommendations but that was a couple of years ago.
I personally didn't think it came near to a mips receiver for ease of use, support and stability (did experience a lot of lock ups/ green screens etc) but that said, it was a few years ago and probably have improved now.
