The "Hot FTF" Method:
A "hot" FTF is a custom-flashable firmware package that contains a modified or region-swapped modem configuration. When you flash it, you trick the phone into thinking it is on a docomo network—or you force it to skip the lock check entirely. The term "hot" signifies that the FTF is pre-patched to neutralize the lock flag upon boot.
Follow this sequence precisely. Do not disconnect the phone halfway. Warning: The SOV33 is a Japanese model (KDDI au)
Thus, the only DIY method left is the "hot FTF" flash – a procedure that forces the phone to overwrite its lock status.
