Cause
This error is caused by the ESC having the default serial number.
For G30 this is one of N4GEA1601C0001, N4GEA1602C0001, N4GSA1602C0001
For G2 this is one of 01GXA1602C0001, 01GVA1602C0001, 01GXA1603C0001
This can happen for any number of reasons but usually happens when flashing a firmware file with the serial number included.
Fix
