I thought i would bring this post back to life as having messed around with a few of these boxes i have yet to find a solution to this problem. If you just use one emulator from the start ie Cccam and never change to a different cam you can update firmware and change channel lists as much as you want without any issues the problem starts when you start using Mgcamd or Newcamd on these boxes.Will fire an email off to him. Thanks for that advice
