B. SIM/Network Unlocking

Bootloader Lock: Prevents you from installing custom ROMs or rooting. This can usually be unlocked via Sony's official developer website (if the carrier allows it).
SIM/Network Lock: Ties the phone to a specific carrier (e.g., KDDI/au in Japan). You cannot remove a SIM lock using an FTF flash file alone. FTF files contain official firmware. If you flash official firmware, the SIM lock remains. You need a specific "Unlock Code" or a paid server unlocking service for SIM unlocks.

The software will automatically download and install the correct firmware, removing the lock in the process. Important Note on FRP Sony SOV33 (Xperia X Performance, au variant) can

The FTF Myth: Users look for an FTF file that will magically change "Bootloader Unlock Allowed: No" to "Yes."
The Reality: You generally cannot change this via a standard FTF flash. The "Bootloader Unlock Allowed" flag is stored in the TA Partition (Trim Area). Standard FTF files do not overwrite the TA partition because doing so can hard-brick the device (losing DRM keys, calibration data, etc.).
The Solution: There is a specific exploit method known as "Dirty Cow" (CVE-2016-5195). This involves rooting the device temporarily to patch the TA partition. It is a complex process that does not rely solely on a single "Lock Remove FTF" file.
