How to flash your Chastity Lockbox
Warning
Only flash your device if instructed to do so by Research and Desire support. If you're experiencing issues, contact support@researchanddesire.com first.
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.
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 Microsoft Edge on a desktop computer
Note
Some USB-C cables only support charging. If your device isn't detected, try a different cable that supports data transfer.
Flashing instructions
Step 1: Connect your device
Plug the USB-C cable into your Chastity Lockbox and connect the other end to your computer.
Step 2: Open the web flasher
Open the LKBX Web Flasher in Chrome or Edge. No account or sign-in is needed. Under Approved channel, keep Production (Stable) unless support asked you to use a different channel.
Step 3: Connect to your device
Click Connect & Flash, select the device labeled USB JTAG Serial Debug (or similar) from the list, and click Connect. The flasher detects your Lockbox hardware (R2 or R8) and selects the matching firmware automatically.
Warning
If no device appears, verify your cable supports data transfer and try a different USB port.
In the window that opens, click Install LKBX….
Step 4: Choose whether to erase device data
When the Erase device screen appears:
- 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.
Step 5: Complete the flash
Click Next, then click Install to confirm. Keep the cable connected and the page visible until the flasher shows Installation complete!
Success
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.
