When replacing the AP board, be sure to skip the step of binding the machine when turning it on for the first time.
After confirming that the replacement is completed, it is necessary to update the SN. To do this, please contact the service team and provide the new and old SN to complete the SN replacement process.
Changing a new AP board does not remove the region lock.
