How to wipe a Trezor device

Understanding the Need to Wipe a Trezor Device

Wiping a Trezor device is an essential security measure that users may need to perform under various circumstances. Whether you're planning to sell your device, reset it due to malfunction, or simply want to start fresh with a new wallet setup, wiping ensures that all private keys and sensitive data are removed permanently. It’s crucial to understand that once a Trezor is wiped, all stored cryptocurrency information will be erased, and recovery can only occur if you have access to the recovery seed phrase.

What Happens When You Wipe Your Trezor?

When you wipe a Trezor hardware wallet, the device performs a secure erase of its internal memory. This includes removing:

• Private keys
• Public addresses
• Wallet configurations
• PIN codes
• Previously set labels

After the wipe, the device resets to factory settings and behaves like a brand-new Trezor. It does not retain any traceable data about previous wallets or transactions. However, it does not delete the blockchain transaction history associated with your public addresses, which remains visible on the blockchain explorer.

Prerequisites Before Wiping Your Trezor

Before initiating the wipe process, ensure the following conditions are met:

• You have your 12 or 24-word recovery seed securely stored.
• You’ve backed up any important wallet labels or notes.
• The device is fully charged and connected to a stable power source.
• You’re using the latest version of Trezor Suite or compatible software.
• You are in a private and secure environment to avoid exposing sensitive data during the process.

Failure to meet these conditions could result in irreversible loss of funds.

Step-by-Step Guide to Wipe a Trezor via Trezor Suite

To wipe your Trezor through the Trezor Suite desktop application, follow these steps carefully:

• Connect your Trezor device to your computer using the provided USB cable.
• Open the Trezor Suite application and allow it to detect your device.
• Enter your PIN code when prompted (if one was previously set).
• Navigate to the Settings menu within Trezor Suite.
• Locate and select the 'Wipe device' option.
• Confirm the action by clicking 'Yes' when prompted.
• Follow the on-screen instructions to complete the wipe process.
• Once completed, the device will display a message indicating it has been successfully wiped.

This method is ideal for users comfortable with desktop applications and who have access to their Trezor Suite interface.

Wiping a Trezor Using the Physical Buttons

If you don’t have access to a computer or the Trezor Suite app, you can still wipe your Trezor directly from the device using its physical buttons. This method works even if the device is locked or has forgotten PIN attempts.

• Press and hold both buttons simultaneously while plugging the Trezor into a power source.
• Continue holding the buttons until the Trezor logo appears.
• Release the buttons and wait for the device to boot into recovery mode.
• Use the buttons to navigate to the 'Wipe device' option.
• Confirm by pressing both buttons together.
• Wait for the process to finish; the device will automatically reboot.

This method is particularly useful when dealing with devices that no longer respond to software commands.

Recovering Funds After Wiping Your Trezor

Once your Trezor has been wiped, you can recover your funds by restoring the wallet using your recovery seed phrase. To do this:

• Power on the wiped Trezor device.
• Select the option to restore from recovery seed.
• Carefully enter each word of your seed phrase using the on-screen keyboard.
• Confirm the entered words match your original backup.
• Set a new PIN code and label for your device.
• Complete the setup and connect to Trezor Suite or another supported wallet service.

Ensure that you double-check each word as entering even one incorrect word can result in loss of access to funds.
