Samsung devices use FBE (File-Based Encryption). This tool removes that barrier, allowing custom recoveries to read your data partition, which is necessary for creating backups (Nandroids) or flashing ROMs.
While powerful, using this tool carries risks. Disabling encryption means your personal data is no longer protected if the device is stolen.

To understand , you must first understand Samsung’s defense system. Since the Android 9 (Pie) and Android 10 (Q) eras, Samsung introduced VaultKeeper and fully enforced dm-verity (device-mapper verity). These features check the integrity of system partitions. If the system detects any modification (like an unofficial recovery or root), it either refuses to boot or throws the infamous "Only official released binaries are allowed to be flashed" error.
Vaultkeeper is a Samsung-specific background service that monitors the bootloader status. If it detects that you have modified the system or unrooted, it can retroactively re-lock certain permissions or trigger a "Prenormal" KG/RMM state, preventing you from flashing custom files via Odin. Multidisabler completely disables this daemon. 3. DM-Verity and Android Verified Boot (AVB)
