default IP address after using reset on senso

I have tried to update a v4 sensor with new firmware. After flashing the green and yellow les were off. I have used the reset button and the green led is on, and the yellow is blinking slowly, that is the same as my other sensors. You manual says that I should connect to the default IP address 192.168.11.160 but I cannot even ping that. What went wrong and how can I revive this sensor?

Uploading the wrong firmware to a device may brick it. The reset will not work and a factory repair is the only option. You can request an out of warranty repair from your order page or from your myServersCheck account
