Thanks a lot! Tristan. Appreciate it.Yes, AIO Tweaks can be installed via USB at your 56.00.240 4A N MZD firmware. Check "copy backup" in the install options in AIO. This should copy backups of the original files, which will be modified by AIO. But there is no such thing as a backup of your whole MZD firmware, that can be created (like you might have it at your PC/Mac).
