Firmware Update

Firmware updates are maintenance operations. When the devices are working normally, there is no need to update repeatedly just to chase version numbers.

Before You Update

• Confirm the firmware is explicitly for your tracker or receiver model.
• Confirm the tracker and receiver firmware versions are compatible with each other.
• Ensure the computer and devices have a stable power supply.
• Close software that may occupy the device port.
• Only use firmware and tools confirmed by Neko Nya.

Do not interrupt the update

Do not unplug the device, close the tool, or let the computer sleep during the firmware write. Using the wrong firmware may make the device fail to start or fail to pair.

How to Check the Version

In the SlimeVR main window, click the tracker you want to check. The device info panel shows the current firmware version.

Select the target device in the tracker list.

The arrow points to the current version number.

Updating Tracker Firmware from a Computer

1. Press the RST function button three times (you can use the button on the charging dock or on the tracker; when operating a tracker directly, gently press the reset hole with a toothpick).

   Connection slots

   Only the four dock slots near the buttons support connecting to a computer.

   

   

2. After pressing RST three times, the tracker enters DFU mode and its red light blinks. Connect it to the computer; a removable disk named tk_boot appears. Drag the latest firmware matching the device from an official source onto it.

Recovery After a Failed Update

If the device cannot be recognized, started or paired after an update, stop flashing repeatedly. Note down the device model, the firmware file used, tool messages and indicator-light state, then contact support.
