Device Management: Updating Firmware After Device Setup

Firmware updates keep your ERA Wallet secure, reliable, and up to date with the latest features and blockchain standards.

This makes the process secure and tamper-resistant, protecting your device from interception while keeping it offline. On the Device 1. Turn on the device by short pressing the physical button. 2. Unlock the device. 3. Press the hamburger menu button in the top-left corner. 4. Open Settings and select Updates. 5. Press Update. 6.

The device's NFC antenna is located on the bottom half of the device. iPhone users: The NFC antenna is located at the top of the phone. Place the top half of the iPhone against the bottom half of the device, exactly as shown in the animation. Android users: NFC antenna placement varies by model. Adjust the phone position until the NFC connection is detected. During the Update 1. Once the phone is correctly positioned, the firmware update will start automatically. 2. Do not move or lift the phone during the update process. 3. Keep the phone in place until the mobile app displays Success. ⚠️ Important for iPhone users: You may see a notification at the bottom of the screen repeatedly appearing and disappearing.

The update is complete only when the mobile app confirms Success.
