3. Run FlashTool > tab Tools > Bundles > Create.
4. Browse your folder prepared at the first step and OK.
5. Press Ctrl+A when all have loaded to FlashTool bundle creator and click right arrow button to load files into Firmware content. Hit Create to start.
6. After finished, open /Flastool/firmware to check the firmware you've made. And it's ready to flash to the device.
