12. Saving and exporting

File → Export Firmware… (Ctrl+Shift+S) writes the full firmware image with the edits to a new file.

• Writing over the source file is not allowed — the original always stays intact.
• Checksums are recalculated automatically for Bosch, Volkswagen Group (VAG) and Mercedes-Benz units; for other families a warning is shown and the checksum fields are not updated. If the recalculation fails, the file is not written: "Failed to recalculate checksums, the file was not saved".
• On closing, importing another file or switching projects with unsaved changes, the program asks: save, cancel or don't save.

If the "Export Firmware…" item is missing from the menu, contact the supplier.

See §5.1.
