⭐ Restore Procedure
1. Connect the device
Connect your MiraBot to your PC using a USB Type-C cable.
2. Open the restore tool

3. Establish a serial connection
Leave the Baudrate at the default value (115200).
Click [Connect], and a serial connection dialog will appear.
Select the port where the MiraBot is connected (e.g., COM8) and click [Connect].

4. Start the restore
Once the connection is successful, select your device model (Lite / S6 / S2+) under Device Type, then click [START].
- The installation log will appear in the Terminal Output section at the bottom of the screen.
- The restore process is complete when the progress reaches 100%.

5. Disconnect
Click [Disconnect], then unplug the USB cable.
⭐ Post-Restore Operation Test
1. Launch MiraPlay AiO
Open MiraPlay AiO and log in to your account.
- If your device was previously paired, it will appear automatically in the device list.
- For first-time setup, please add the device before running tests.
2. Run the motion test
Go to My → Motion Test.
Each slider corresponds to a motion axis.
Move each slider to confirm all axes operate normally.
Displayed axes differ by model:
- S6: 6 axes (including Twist)
- Lite / S2+: 4 axes (including Twist)

⭐ Initial Position Check (Horizontal Alignment)
After powering on, check whether both arms are aligned on the same horizontal plane in their initial position.

If alignment is off:
- Open My → Arm Initial Settings.
- Fine-tune each axis using + / −, based on the default value (1500).
- + = clockwise micro-adjustment
- − = counterclockwise micro-adjustment

⭐ Common Troubleshooting
If the restore doesn’t progress:
- Ensure the correct USB/COM port is selected
- Try another USB port or cable
