The Hardware Context: When Sony Found Its Groove

Before diving into the software, it is essential to understand the vessel. Released in late 2016, the Xperia XZ was the phone where Sony finally fixed its biggest criticism: the camera. Moving away from the 20.7MP sensors of the Z-series, the XZ introduced the 23MP Exmor RS sensor with laser autofocus and the RGBC-IR sensor for true-to-life color reproduction.

The SO-01J variant was physically distinct from its global siblings due to Japan’s unique mobile infrastructure. It came equipped with FeliCa (NFC integration for Japanese e-money and transit cards) and a dedicated TV antenna for 1-Seg digital broadcasting. These hardware features required a specific software branch—the Stock ROM—that global models simply did not have.

📞 Network & Carrier Features

• VoLTE works only with Docomo SIM or compatible MVNO.
• Wi-Fi Calling supported only on Docomo network.
• APN settings auto-configure for Docomo, may need manual entry for other carriers.

Identifying the Correct Firmware Version

Sony and Docomo released several builds for the SO-01J. The most common official versions include:

• Android 6.0.1 (Marshmallow): Build 39.0.B.1.117 (Original launch firmware – very rare now).
• Android 7.0 (Nougat): Build 39.2.B.0.137 – Improved battery life.
• Android 7.1.1 (Nougat): Build 39.2.B.2.31 – Security patch updates.
• Android 8.0 (Oreo): Build 39.3.B.0.19 – Final major update for SO-01J, introduced picture-in-picture and autofill.

Check your current build by going to Settings > About Phone > Build Number. Ensure the firmware you download matches or is newer than your current version to avoid downgrade errors (though forced downgrades are possible via FlashTool with a data wipe).
