KC868-A16 dead?

[stanchiam]

Was using the kcs AP to connect and update the settings, suddenly it just cannot communicate, no response.
Tried pressing the download button on the a16 for more than 10 seconds to factory reset but still no response.

I try using esptool to dump/flash but will not be able to communicate with it
Also try using esphome also same.

Not sure what happened, other a16 working fine so not cable issue.

   
   

It will just keep on showing dots
