J730f U8 Auto Patch Firmware [cracked] -

: The "U8" (or S8/B8) signifies the Binary Bit version of the device's bootloader. Samsung implements a security measure where you cannot downgrade to a lower binary level. Since this is Bit 8, the firmware is intended for devices updated to the later stages of the J7 Pro's lifecycle (typically Android 9.0 Pie).
