Searching for the newest version is risky for three reasons:
Yes. Always note your presets before updating. A factory reset after the update is recommended anyway.
Generally no. Most MP1769 updates are irreversible. Downgrading can corrupt the bootloader.
Navigate to the official Alpha Coustic website (if still active). Look for a "Support" or "Downloads" section. Search for "MP1769". If the official site is down, many manufacturers redirect to a third-party repository.
