Hi!
We have 2 ms28's! done via vcc trick performed very neat with xtreme 4.2b
Came back to us after they performed the fall update giiving e66!
Reflash back to orig.bin gives an e65? then reflash to 4.2b the dash is back but then no disc will read!
Tried older versions like 3.3 with no luck

This is definately somekind of software problem, not power damage from what i can gather with these boxes!
Seems were going round in circles here but flashing orig.bin doesn't work at all! why when its the correct unique key!
Only thing i haven't tried is turning the ms28's into ms25's as I believe this can be now done! worth a try? or any other advice please feel free to comment!
Cheers!
