Issue description

After connecting your F1/F1 Lite to the computer using the USB cable, its name does not appear in the Available devices list in xTool Studio, as shown in the image below.

Possible causes

• Machine is not powered on
• USB cable or connector is damaged
• Non-original USB cable is used
• USB cable is connected to the wrong port
• Mac USB dock connection issue
• Computer specifications are too low (outdated macOS or low Windows configuration)
• Required driver is not installed or is missing
• Computer firewall blocks USB device detection (Norton Firewall may block USB port detection by default, so manually enable this setting to allow the computer to detect newly connected devices.)
• VPN is enabled
• Connection issue caused by a new software or firmware version

Troubleshooting

Step 1

1. Make sure the device is powered on. Check whether the logo indicator is lit or red and blue light spots are visible on the baseplate.

2. Make sure you are using the latest version of xTool Studio. Then restart the device and check whether it can connect properly.

3. Check whether your computer meets the minimum system requirements.

4. Go to xTool Studio Settings and click Start next to Connection detection. After the detection is complete, check whether the device can connect properly.

5. If an error occurs at any point during the xTool Studio connection detection and prevents the device from connecting, as shown in the image below, proceed to Step 2.

Step 2

Troubleshoot the issue based on the errors identified during connection detection. See the following solutions for each type of connection error.

Physical connection detection error

1. Make sure you are using the USB cable included in the F1/F1 Lite package and that it is properly connected to the device's port for USB cable, as shown in the image below.

2. Try using a different USB cable and a different USB port on your computer to connect the device again.

3. If you are using a desktop computer, connect the USB cable to a USB port on the back of the computer.

4. Avoid using a USB hub whenever possible. If you must use one, make sure its USB port supports data transfer. You can verify this by connecting a phone to your computer through the port and checking whether files can be transferred normally. Also, avoid connecting multiple devices to the USB hub at the same time, as this may cause unstable power delivery to its USB ports and result in connection failure.

5. If possible, try connecting the device to another computer.

Driver detection error

Go to xTool Studio Settings > Device in the software and check whether the RNDIS driver is installed on your computer. If the RNDIS driver has not been installed successfully, click the button on the right to install it.

Data transfer detection error

If the connection detection shows an error only at this step, provide the software logs (Item 2 in the linked instructions: xTool Studio debug file) and contact us.

Proxy & firewall errors

1. Troubleshoot VPN and proxy settings

First, quit any VPN software that is currently running, such as V2Ray, Clash, or Cloudflare, and disable the proxy settings in your system settings.

Windows settings path:

Go to Settings > Network & internet > Proxy. Make sure the proxy server is turned off, then try connecting the device again.

If the connection cannot be restored, reset the network configuration by following the steps below and try again. (Windows only)

(1) Right-click the Windows icon and open Terminal (Admin).

(2) Enter the command netsh winsock reset and press Enter.

(3) Restart your computer and try connecting the device again.

macOS settings path:

Go to System Settings > Network > Wi-Fi > Details > Proxies and make sure all proxy servers are turned off.

2. Troubleshoot firewall settings

Manually turn off the system firewall and try connecting the device again. If third-party antivirus software with a network firewall feature is installed on your computer, temporarily quit the software and try connecting the device again.

Windows settings path:

Search for Firewall in the search bar, select Turn Windows Defender Firewall on or off, and turn off Windows Defender Firewall for all network types.

macOS settings path:

Go to System Settings > Network > Firewall and turn off the firewall.

Local network permission errors (macOS only)

Enable local network accessfor xTool Studio by following the path below. If it is already enabled, quit xTool Studio, turn the setting off and then back on, and reopen the software.

Go to System Settings > Privacy & Security > Local Network, and turn on local network access for xTool Studio.

Computer health errors

1. If you are using a laptop, make sure it is connected to a power adapter, has sufficient battery power, and Low Power Mode is turned off.

2. If you have third-party antivirus software installed, quit the antivirus software and then try connecting the device again.
