Hello Support Team, 

I am seeking technical assistance for a Tangara device that is no longer functioning. Firmware was successfully updated to 2.0.

Issue Description:

• The device is completely unresponsive; the screen remains off.
  
• The rotation wheel no longer provides haptic feedback when turned.
  
• Companion software does not detect the device when it is plugged in and powered on.
  

Troubleshooting Attempted:

• Performed a hard reset (previously effective, but now unsuccessful).
  
• Left the device plugged in for over 24 hours to rule out a dead battery.
  
• The device was working as recently as last week, and I have not attempted to open it.
  

Could you please suggest further troubleshooting steps or advise on repair or replacement options?

I also have two specific questions:

• Is it possible to replace the battery?
  
• Since the device does not work even while plugged in, does this suggest the issue may not be battery-related?
  
• When I switch the device on and plug it into the USB-C port, Windows Device Manager does not detect it at all. Could this indicate a faulty USB port on the device, or does it point to another underlying issue?
  

Thank you for your guidance. 

Best regards,
Bryan
