+

+2. Extract the contents of the archive: `tar zxvf uconsole_keyboard_flash.tar.gz`.
+3. Install the required package using the following command: `sudo apt install -y dfu-util`.
+4. Navigate to the extracted directory: `cd uconsole_keyboard_flash`.
+5. Execute the flash script with root privileges: `sudo ./flash.sh`.
+6. If everything goes well, you will see a progress bar indicating the flashing process.
+7. If any issues occur or the keyboard loses control (which is unlikely), simply reboot uConsole to resolve it.
+8. Rest assured that this flash program will not brick your keyboard.
