Firmware Update (from computer)

Firmware update indicator

Whenever new coin support is added or bug fix has been made, a new firmware will be available for installation. Your mobile app will show an indication when a newer version of the firmware is released.
Firmware update can be done only from the PC or Mac.

Before you update the firmware

Make sure you have your Mnemonic Code (24 seeds/words) for recovery
24 words were provided during the Initial Setup of your Biometric Wallet and you have written them down on the recovery card. Make sure you still have the recovery card. Unlike other products, your wallet will still remain safely intact inside the secure chip even after updating the firmware. This means that you don't need to recover your wallet every time you update the firmware as other products requires you to do. (Keep your recovery card secured and ready just in case your Biometric Wallet is no longer accessible, possibly due to "brick"ed device or something that went wrong during the update process.)
After you update the firmware, you cannot roll-back to the previous version
To perform the firmware update, use the USB cable that came included inside the original D'CENT package. Firmware update will take approximately 10 minutes to complete.
It is recommended that the D'CENT mobile app is not running during the firmware update.
