To remove a screen lock or Google account (FRP) lock from a Sony Xperia X Performance (SOV33) Go to product viewer dialog for this item.

If you own a Sony SOV33 (a Japan-market variant, often from au by KDDI) and need to legitimately remove a network or screen lock, I recommend:

Load the FTF: Select your downloaded lock-remove file. In the "Wipe" section, ensure USERDATA is checked to ensure the lock screen is cleared. Connect in Flashmode: Turn off your phone completely.

Cons/Risks of this method:

Q3: My phone says "No Service" after hot flash. What happened?

The radio partition (modem) wasn’t properly flashed, or you overwrote NV items. Solution: Flash back stock FTF + restore TA backup.

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.
