How to reflash a bricked ihost?

Hello, after I tried to update to latest cube OS my iHost can’t start, only breathing red LED and not connects to the router (link leds are off, tried with another LAN cable, router port tested with another device). I think firmware update failed and can’t boot ihost. Please help me how I can reimage my ihost?

Thank you for your feedback. We sincerely apologize for the inconvenience caused by the iHost failing to start.

To help our technical team accurately identify the issue, could you please provide the following information:

  1. Please unplug the iHost power, then plug it back in, and record a video of the LED indicator status during the startup process (especially the rhythm of the red breathing light). The LED behavior is very important for our troubleshooting.

  2. Have you previously used an SD card to re-run the Home Assistant system on the iHost?

Once we receive your reply and the video, we will analyze the issue and provide a solution as soon as possible. Thank you for your cooperation!
