[Check Cable and Connection]​

  • Confirm that your OTG adapter or USB-C to C cable supports data transfer
  • Cables that are charging-only cannot be used for firmware updates
  • If your wallet has a Micro USB 5 PIN port, and you are using a DCENT official 2-in-1 OTG cable, please refer to the image below to ensure proper connection

[Check for Access Allow Popup]​

  • When the wallet is properly connected to your phone, you should see a popup on your screen that says:
    "Allow DCENT to access DCENT?"
  • You must tap [OK] to proceed with the firmware update
