it would be nice if it were clone detection,one of my theories is the clones only have a 4meg flash just enough for the firmware updates.I have clone firmware from aug 2013 and it won't work on the genuine box,which doesn't make sense unless the clone detection was in the receiver itself before you even load the firmware(hardware mismatch error)
It would be nice to be able to load f1,f2,f3,f4, firmware as an example.The protection ic in the receiver (u9) has no numbers on it but is probably similar to the security eeprom in the previous models.
