**Fixing the “UsbDk Not Installed” Error When Searching for a Device in DFU Mode**

If you encounter the error message “searching for device in dfu… usbdk not installed please install it,” it typically means that the necessary UsbDk drivers are missing on your system. Here’s a step-by-step guide to resolve this issue:

### 1. **Understanding the Problem**

– **DFU Mode**: DFU (Device Firmware Update) is a mode where a device is ready to receive firmware updates. For iPhones, this is often used during jailbreaking or restoring.
– **UsbDk**: This is a USB development kit that allows low-level communication with USB devices, essential for DFU operations.

### 2. **Installing UsbDk**

– **Download**: Visit the official GitHub repository to download the latest version of UsbDk: [GitHub – UsbDk](https://github.com/daynix/UsbDk).
– **Installation**:
– Run the installer. If it fails, try a manual installation by extracting the files and running `UsbDkController.exe` with the `-i` flag.
– Ensure you have administrative privileges during installation.

### 3. **Handling Driver Signing Issues**

– **Windows Settings**: On newer Windows versions, unsigned drivers may be blocked. To allow them:
– Go to **Control Panel > System and Security > System > Advanced system settings**.
– Under the **Startup and Recovery** section, click **Settings** and check **Automatically restart**.
– Restart your computer and press F8 to boot into Advanced Boot Options, then select **Disable driver signature enforcement**.

### 4. **Post-Installation Steps**

– **Restart Your Computer**: This ensures all drivers are properly loaded.
– **Check Device Manager**: Look for any errors related to USB devices and ensure all drivers are up to date.

### 5. **Using Tools Like iPwnder**

– **iPwnder**: This tool can help put your device into DFU mode. After installing UsbDk, use iPwnder to connect your device.
– **Troubleshooting**: If issues persist, check the official forums or communities for additional support.

### 6. **Troubleshooting Tips**

– **Unplug and Replug**: Sometimes, simply removing and reconnecting the device can help.
– **Check for Updates**: Ensure your system is up to date, as some updates resolve driver compatibility issues.
– **Reinstall UsbDk**: If problems continue, uninstall and reinstall UsbDk.

### 7. **Additional Resources**

– **GitHub Repository**: [UsbDk GitHub](https://github.com/daynix/UsbDk)
– **Forums and Communities**: Platforms like XDA Developers or Reddit can offer peer support.

### 8. **Final Notes**

– **Caution**: Working with low-level drivers can be risky. Always ensure your system is backed up before making changes.
– **Stay Updated**: Keep your software and drivers current to avoid compatibility issues.

By following these steps, you should be able to resolve the “UsbDk Not Installed” error and successfully communicate with your device in DFU mode. If issues persist, consider reaching out to the developer community for further assistance.
