## When to flash your device

Flashing reinstalls the firmware and can resolve:

* Device continuously restarting on its own (power cycling or boot loop)
* Device freezing when pressing menu buttons
* Unresponsive screens or buttons after waking from sleep
* Software glitches that persist after a hard reset

<Tip>
  Before flashing, try a hard reset first: hold the **Enter/Lock** button for 10 seconds. If the issue persists, proceed with flashing.
</Tip>

## Prerequisites

Before you begin, ensure you have:

* A USB-C cable that supports **data transfer** (not just charging)
* A computer with an available USB-C port
* Google Chrome or another Chromium-based browser

<Note>
  Some USB-C cables only support charging. If your device isn't detected, try a different cable that supports data transfer.
</Note>

## Flashing instructions

<Steps>
  <Step title="Connect your device">
    Plug the USB-C cable into your Chastity Lockbox and connect the other end to your computer.
  </Step>

  <Step title="Open the web flasher">
    Navigate to [the webflasher page](https://dashboard.researchanddesire.com/app/tools/web-flasher) in your browser.
  </Step>

  <Step title="Connect to your device">
    Click **Connect** and select the device labeled **USB JTAG Serial Debug** (or similar) from the list.

    <Warning>
      If no device appears, verify your cable supports data transfer and try a different USB port.
    </Warning>
  </Step>

  <Step title="Choose whether to erase device data">
    When prompted with the **Erase device** checkbox:

    * **Do NOT check the box** if you want to keep your current settings and lock state. This reinstalls the firmware while preserving your data—ideal for fixing freezing issues.
    * **Check the box** if you want a full factory reset that erases all settings.

    <Info>
      Either option preserves your dashboard pairing. Your Lockbox remains connected to your account.
    </Info>
  </Step>

  <Step title="Complete the flash">
    Click **Next** to begin the flash process. Wait for it to complete.
  </Step>
</Steps>

<Check>
  Once complete, your device restarts. If you erased the device, it displays the calibration screen—see the calibration guide for next steps. If you didn't erase, the device returns to normal operation.
