Firmware Update (from computer)

Firmware update indicator​

Whenever D'CENT adds support for a new coin or releases a bug fix, new firmware becomes available. The mobile app shows a notification when a newer firmware version is released.

info

Firmware updates can be performed from a PC or a Mac.

Before you update the firmware​

danger

Make sure you have your Mnemonic Code (24 seeds/words) for recovery

During the initial setup of your Biometric Wallet, you wrote 24 recovery words on your Recovery Card. Make sure you still have that card before continuing.

Unlike other hardware wallets, your D'CENT wallet remains safely stored inside the secure chip even after a firmware update. You do not need to recover your wallet every time you update.

(Still, keep your Recovery Card on hand in case your Biometric Wallet becomes inaccessible — for example, if the device gets bricked or something goes wrong during the update.)

warning

Once the firmware is updated, you cannot roll back to a previous version.

The firmware update takes approximately 3 minutes to complete.

info

We recommend closing the D'CENT mobile app before starting the firmware update.

How to update firmware​

Requirements for the firmware update​

✅ Firmware can ONLY be updated from a personal computer running a 64-bit OS (Windows or Mac).

✅ You must use the Google Chrome browser.

✅ You must use a USB cable that supports data transfer.
(If your Biometric Wallet uses a Micro USB 5-pin port, we recommend the USB cable included in the package.)
