This app is able to mass erase a STM32Fx and flash it with firmware from a .dfu file. See the accompanying youtube video for a demonstration
The USB_VENDOR_ID and USB_PRODUCT_ID in the MainActivity.java file must match your STM32 device, otherwise the app will not recognize the usb device.
Once your device info is displayed int the text field, you are ready to perform two actions.
Press Mass Erase Button to completely wipe the Flash memory excluding the Option Bytes. This might take 15 seconds depending on the Flash size and app will not respond until its finished.
Press Program Button: This will load the .dfu file from Download Folder and sent to attached Device. Once the file is downloaded it will automatically start the new program downloaded. If you want to Mass Erase, reconnect the cable and restart the app.

Only one .dfu file must be located in the internal Download folder. The .dfu file must be compiled using dfuSE version1 (tested with DFU File Manager 3.0.3) with at most one element file for at most one target. Does only mass erase the complete flash memory. The image file size must not exceed the target device flash memory capacity. Any errors during programming are ignored by clearing the status.
On some STM32F devices, It takes several tries to recognize the USB device.
