Make sure to install qFlipper from official sources, such as the [Flipper Zero Firmware Update](https://flipperzero.one/update) page and [Official documentation](https://docs.flipper.net/zero/qflipper). :::Iframe{iframeHeight="0" code="
qFlipper is compatible with Windows 10 and 11 only.
"} ::: *** # Updating qFlipper Make sure qFlipper is up to date: ::::WorkflowBlock :::WorkflowBlockItem Connect your Flipper Zero to your computer via a USB-C cable. ::: :::WorkflowBlockItem Run qFlipper and go to the **Advanced controls** tab. ::: :::WorkflowBlockItem Click **CHECK APP UPDATES**. ::: :::: ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/rZl68q0oA3jL9BRQXUhlh_monosnap-miro-2023-11-29-16-55-49.jpg "You can easily update qFlipper") *** # Checking if the correct drivers are installed Depending on the mode in which you connect your Flipper Zero to a computer, the device can be defined by Windows as a **Serial device** or **DFU device**. We recommend checking drivers for both cases. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/mfh6yMHZTE8c8-mGx8hj__monosnap-miro-2023-06-15-19-38-42.jpg "Your computer recognizes your Flipper Zero differently") *** ## Checking the Serial device driver When the device is connected to a computer in **Normal mode** (with the running operating system), the device is recognized as a **Serial device**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/fijc_1VwICpXE0KzgLtVp_monosnap-miro-2023-06-14-18-09-33.jpg "The Flipper Zero with the active operating system") To check if the correct Serial device driver is installed, do the following: ::::WorkflowBlock :::WorkflowBlockItem On your computer, close **qFlipper** if running. ::: :::WorkflowBlockItem Connect your Flipper Zero to the computer via a USB-C cable. ::: :::WorkflowBlockItem Go to **Device Manager -> Ports (COM & LPT)**. ::: :::WorkflowBlockItem If there are multiple devices, make sure the detected **USB Serial Device** is your Flipper Zero: 1. Double-click the **USB Serial Device** and go to the **Details** tab. 2. Set **Property** to **Hardware Ids**. 3. Check if the **Vendor ID (VID) is 0483** and **Product ID (PID) is 5740**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/sTRvMG5cfX94VFqAC9XNW_image.png) ::: :::WorkflowBlockItem Go to the **Driver** tab and ensure that the default **Microsoft** driver is installed. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/r9nIooW8afV_9ThNlO7i9_image.png) ::: :::WorkflowBlockItem If there is a different driver, uninstall it and reconnect your Flipper Zero to the computer. The Microsoft driver will install automatically. ::: :::: ### Checking for COM port conflicts There is a bug in the Windows operating system that occurs when two different Serial devices bind to the same port number. To check for conflicts, do the following: ::::WorkflowBlock :::WorkflowBlockItem On your computer, close **qFlipper** if running. ::: :::WorkflowBlockItem Connect your Flipper Zero to the computer via a USB-C cable. ::: :::WorkflowBlockItem Go to **Device Manager -> Ports (COM & LPT)**. ::: :::WorkflowBlockItem Check if you have Serial devices with the same COM port number. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/J4LXo2A8nd3Lweh77GSEL_image.png "Check if you have two USB Serial devices with the same COM port number") ::: :::: If you have a COM port conflict, do the following: ::::WorkflowBlock :::WorkflowBlockItem Double-click one of the devices. ::: :::WorkflowBlockItem Go to **Port Settings -> Advanced**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/_nFP10WpkN39KmSuDMzyB_image.png) ::: :::WorkflowBlockItem Assign a **COM Port Number** that is currently not in use and click **OK**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/vJeNH5DefhUs0PIXCNPpw_image.png) ::: :::: *** ## Check the DFU device driver When the device is connected to a computer in **Recovery mode** (the operating system isn’t running), the device is recognized as a **DFU device**. To check if the correct DFU device driver is installed, do the following: ::::WorkflowBlock :::WorkflowBlockItem [Reboot your Flipper Zero to Recovery mode](https://docs.flipper.net/zero/basics/firmware-update/firmware-recovery#2vuS0): 1. Press and hold the %left%**LEFT** and %back%**BACK** buttons simultaneously. 2. Release the %back%**BACK** button, but don’t release the %left%**LEFT** button until the blue LED lights up. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/Vbhs4BXkxnme7INQGKY8f_image.png "The Flipper Zero in Recovery mode") ::: :::WorkflowBlockItem On your computer, close the **qFlipper** application if running. ::: :::WorkflowBlockItem Connect your Flipper Zero to the computer via a USB Type-C cable. ::: :::WorkflowBlockItem Go to **Device Manager -> Universal Serial Bus devices**. ::: :::WorkflowBlockItem Make sure that the connected device has the name: **DFU in FS Mode**. ::: :::WorkflowBlockItem If there are multiple devices, make sure the detected **DFU in FS Mode** device is your Flipper Zero: 1. Double-click the **DFU in FS Mode** device and go to the **Details** tab. 2. Set **Property** to **Hardware Ids**. 3. Check if the **Vendor ID (VID) is 0483** and **Product ID (PID) is DF11**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/UJsgfsw34RHTmrAa_F9X4_image.png) ::: :::WorkflowBlockItem Go to the **Driver** tab and make sure that the driver’s name is **STMicroelectronics**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/5eEQjLXVec3YPW-Ed0RHg_image.png) ::: :::: ### If you couldn’t find the DFU device If you couldn’t find the DFU device in **Device Manager -> Universal Serial Bus devices**, it means that the incorrect driver is installed or the DFU device driver is missing. You can resolve the wrong driver issue by doing the following: ::::WorkflowBlock :::WorkflowBlockItem Go to **Device Manager -> Universal Serial Bus controllers**. ::: :::WorkflowBlockItem Look for the **STM Device in DFU mode** (this is the wrong driver). ::: :::WorkflowBlockItem If you found it, uninstall the **qFlipper** application in **Apps & features**. ::: :::WorkflowBlockItem Download the **qFlipper installer** from [the official sources](https://docs.flipper.net/zero/qflipper/windows-debug#PR64B) and reinstall the application. ::: :::WorkflowBlockItem Check if the **DFU device** appeared in the **Universal Serial Bus devices** section, then check the driver. ::: :::: If there is no such device, manually install the missing device by doing the following: ::::WorkflowBlock :::WorkflowBlockItem Go to **Device Manager -> Other devices**. ::: :::WorkflowBlockItem Look for the **DFU in FS Mode** with an exclamation sign and right-click it. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/ZW4v6PlFd8GU_51HSgiBl_image.png) ::: :::WorkflowBlockItem Go to **Update driver -> Browse my computer for drivers -> Let me pick from a list of available drivers**. ::: :::WorkflowBlockItem Select **Universal serial bus devices** and click **Next**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/rpHtz9VWa1u4Cg30Uz1RY_image.png) ::: :::WorkflowBlockItem Select **WinUsb Device -> WinUsb Device** and click **Next**. ![](https://api.archbee.com/api/optimize/3StCFqarJkJQZV-7N79yY/l3kHVZPxBzEvWTqwnN7jM_image.png) ::: :::WorkflowBlockItem Check if the **DFU device** appeared in the **Universal Serial Bus devices** section, then check the driver. ::: ::::
