Sony Sov33 Lock Remove Ftf Better ((exclusive)) Instant

Complete guide — Remove network (SIM) lock from Sony SOV33 (DoCoMo)

Warning: Unlocking a carrier-locked phone may violate your carrier’s terms, can void warranties, and risks data loss or bricking if done incorrectly. This guide is for informational purposes only. Proceed at your own risk. Back up all data first.

Step 2: Prepare Flashtool

  1. Install Flashtool.
  2. Navigate to C:\Flashtool\drivers\ and run Flashtool-drivers.exe. Install Flashmode and Xperia XZ Premium (G8141) drivers (they work for SO-33J).
  3. Copy your lock-removal FTF into C:\Users\[YourName]\.flashTool\firmwares\.

Prerequisites (Do not skip)

Before you attempt the better lock removal, gather these:

  1. Windows PC (10 or 11) with admin rights.
  2. Flashtool v0.9.34.0 or newer (XperiFirm integrated).
  3. Original Sony USB drivers & Flashmode drivers (installed via Flashtool/drivers folder).
  4. Your SO-33J with at least 50% battery.
  5. Patched FTF file – You have two options:
    • Option A: Build your own using UnSIN and a hex editor (Advanced).
    • Option B: Download a pre-modified "SO-33J_LOCKREMOVED.ftf" from XDA/4pda (Check SHA256 hashes for safety).

Warning: Flashing the wrong FTF can hard brick your SO-33J. Do not flash G8141 FTF without stripping the partition loader (boot_delivery.xml).

Issue 3: Android 9 (Pie) Relocks the phone

Never take an OTA update to Android 9 after flashing. The G8141 Pie update re-introduces region locking. Stay on Android 8 (Oreo) 47.1.A.12.235 for permanent unlock. sony sov33 lock remove ftf better

Procedure

  1. Download the correct stock FTF using XperiFirm inside Flashtool. Select SOV33 (au KDDI) and download the latest Android 9 firmware (47.2.A.11.xx). Do not close XperiFirm – it automatically creates the FTF.

  2. Modify the FTF for lock removal (the “better” step):

    • Use Flashtool’s bundle creation tool to exclude the userdata.sin and persist.sin files. This prevents user data wipe.
    • To remove carrier lock, also replace amss_fsg.sin and amss_fs_1.sin with patched versions from developer communities (e.g., from XDA’s SOV33 unlock thread). These files control SIM lock verification.
    • For screen lock removal, include only system.sin, kernel.sin, and oem.sin. Flashing these overwrites the lock screen database (located in /data/system/) but keeps media files intact.
  3. Flash the modified FTF:

    • Turn off the SOV33. Press and hold Volume Down while connecting USB to enter Flashmode (green LED).
    • In Flashtool, select “Flash device” → “Flashmode” → choose your custom FTF.
    • Check “Wipe userdata” only if you want a full reset; uncheck it to preserve personal files while still removing screen lock.
  4. After flashing, reboot the device. For SIM lock removal, insert a non-au SIM card. The patched firmware should skip carrier validation. For screen lock, the device will boot without any PIN/password prompt.

The Verdict: Is it worth it in 2025?

The Sony SOV33 features a Snapdragon 820 and a 5.2-inch 1080p display. By modern standards, it is slow and the battery life is poor.

However, for the niche community of Walkman enthusiasts (who want the LDAC Bluetooth codec) and compact phone lovers, the SOV33 is a treasure. The “FTF lock remove” method is better because it respects the device’s age—it’s free, it fixes the radio properly, and it requires no recurring subscription.

Final Advice: If you are new to flashing, pay for the tool. If you are a hobbyist with a steady hand for test points and a copy of Flashtool, the FTF method is the only way to truly liberate the SOV33 from its Japanese carrier grave.
