An "official stock ROM" is the operating system released by Sony Mobile Communications. Unlike custom ROMs (like LineageOS or Pixel Experience), a stock ROM retains the native Xperia UI, DRM keys functionality, camera algorithms (including the Motion Eye sensor), and all proprietary Sony features. "Official" means it has not been modified, repacked, or tampered with by third-party developers.

Warning: Flashing will wipe your user data (unless you exclude the userdata partition). Backup photos, contacts, and documents before proceeding. Places to avoid:

If you cannot use XperiFirm due to network restrictions, the XDA Developers forum is the only recommended alternative. Look for threads titled:

Places to avoid:

  • Click “Install”.
  • Install FlashTool on Windows (FlashTool requires .NET and drivers). Use the latest stable Flashtool release from the official Flashtool site.
  • Ensure battery ≥ 50%.
  • Enable USB debugging in Developer Options (not always required for FlashTool, but useful).
  • If device is locked bootloader and you require unlocking, follow the official Sony bootloader unlock procedure first (unlocking will wipe data).
