Door & Window Sensor P2 Firmware Update Issue 1.0.1.1

Today, I attempted to update my P2 door sensor to firmware version 1.0.1.1 using the Aqara app. The firmware downloaded successfully, but it seems the hub failed to upload it to the sensor. Since then, the sensor has lost connection to both my Aqara hub and Apple HomeKit.

I tried resetting the sensor by pressing the button 10 times, but there was no response — not even a blinking light. I also replaced the battery, but the sensor still doesn’t power on.
What should I do next?

Hello @funeru , you need to contact support service support@aqara.com
