Hi there! I see your XIM MATRIX is stuck on a solid blue light after updating, and it’s still not working. Let me help you get this sorted out.

The solid blue LED usually means the device is in firmware programming mode. Since you've already updated the firmware and it remains stuck, let's try a few troubleshooting steps:

1. Check USB Connection:
- Try using a different USB cable, as sometimes faulty cables can cause this issue.
- Also, plug the XIM MATRIX into a different USB port on your Windows PC to rule out port problems.

2. Restart Your PC:
- A simple reboot can sometimes resolve device detection issues.

3. Disable Antivirus Temporarily:
- Some antivirus or security software can interfere with the device’s connection. Temporarily disable it and see if it helps.

4. Update or Reinstall XIM MATRIX Manager:
- Make sure you have the latest version of the XIM MATRIX Manager app installed. If yes, try reinstalling it to fix any corrupted files.

5. Firmware Update Retry:
- Run the firmware updater again while the device is connected directly to your PC (avoid USB hubs).
- If the updater doesn’t detect the device and it remains solid blue, switching USB cables as mentioned above can make a difference.

6. Check for Hardware Issues:
- Inspect cables and connections for damage or loose connections.

If none of these steps help, it might be useful to try downgrading the firmware temporarily, as some users have found success this way, but proceed cautiously—make sure you back up your settings first.

Would you like me to guide you through any of these steps in detail? Also, please let me know if you’ve already tried any of them.
