SYMPTOMS
When a system on a chip (SoC)-based set-top box (STB) undergoes the bootstrap process, the STB sends the device maker information and the device model information to the bootstrap server. You expect the DeviceMake value to be a constant value. However, the DeviceMake value changes according to the certificate that is loaded on the STB device.

For example, on a Motorola SOC-based STB device, you see the following information:

DeviceModel=&quot;VIP1200_DEV&quot; DeviceMake=&quot;STB Sub-CA 1&quot;

DeviceModel=&quot;VIP1216_DEV&quot; DeviceMake=&quot;STB Sub-CA 1&quot;
