The user has an ENH202v1 with old firmware that does not yet have the firmware check feature. The user uploaded the ENH500v1 firmware v1.5.6 to the ENH202v1 and though he can still access the ENH202 GUI, the ENH202 understandably no longer broadcasts.
Upload an old ENH500 firmware, which does not have the firmware check feature-such as the ENH500 firmware version 1.1.0. to the ENH202v1.
After loading the old ENH500 firmware, load the device with the ENH202 1.1.9 firmware.
Once the ENH202 1.1.9 firmware is loaded successfully, you can upload the device with the latest ENH202 firmware which is version 1.5.2.
