2.If your machine has a serial number, then it can prove that your machine is a genuine Zhuowei machine, a regular manufacturer's, then is it the machine issued to you in the village village project of the Radio and Television Bureau? That is to say, has the serial number of your machine been filed in **?

If there is no same, it cannot be upgraded, and only the genuine machine installed by the local radio and television bureau can be upgraded.

6.Then power off the slave and restart, you will find that the program of the slave is the same as that of the master.
