I downloaded the Superuser app from the Google play store, installed it and after a reboot the box freezes on the "MBOX" logo screen. I have googled this and there are numerous angry people out there as its also shagged their box. So just a warning to all the members that if you have one of these boxes I suggest you don't try the superuser app or even try to unroot it.

I am in the process of re-flashing the box with the official image. If it works ill post my findings later on
