Q: Do I need a new dongle or license for version 340?
A: No. If your Miracle Box dongle works with 339, it will work with 340. However, licenses purchased before 2021 require a free 5-minute online reactivation.

Q: Will my saved settings (like custom DA files) transfer?
A: Yes. The updater preserves the User_Data folder. Custom loaders in Loader\Custom remain untouched.

Q: Can I downgrade to 339 if 340 causes issues?
A: Yes. Run the Rollback_to_339.exe located in the Backup_339 folder on your desktop. This removes all 340 modules and restores system registry entries.

Q: Why does 340 ask for firewall permissions?
A: The new version includes online IMEI database verification and automatic driver updates. This requires outbound HTTPS connections to api.miraclebox.net. No software is perfect

Q: Is there a portable version without dongle?
A: No. The dongle remains mandatory for all builds to prevent piracy. The update does not change this.
