Flashing Stock Firmware (Example: Restoring an Xperia Z3)

1. Prepare FTF file:
   • Open FlashTool → Click the lightning bolt icon → Select “Flashmode” → OK.

2. Place FTF – Move the .ftf file to C:\Users\[YourName]\.flashTool\firmwares.
3. Start flashing:
   • Click the lightning bolt → Flashmode.
   • Select your FTF from the left pane. On the right, choose which partitions to wipe (check “Data”, “Cache”, “AppsLog” for a clean flash).

Security Implications

It is worth noting that FlashTool 0.9.18 has no authentication mechanism. Any rogue USB device claiming to be MediaTek preloader can accept a malicious DA. While this is a power user’s dream, it also means: Xperia Z Series: Z (L36h), ZL, ZR, Z1

• Never download a pre-compiled FlashTool 0.9.18 from an untrusted source (many bundles on file-hosting sites contain injectors for the Sality virus).
• The official source was shut down in 2017. Legitimate copies are archived via the Internet Archive’s wayback machine from launchpad.net or androidmtk.com circa 2016.

Key Features of Version 0.9.18

1. Stable FTF Creation: This version includes a robust .sin to .ftf converter. It allows users to bundle raw firmware files downloaded via XperiFirm into a single flashable package without corruption errors.
2. Improved Driver Handling: Version 0.9.18 introduced a separate driver installer utility (driver.exe) which dramatically reduced "driver not found" errors common in earlier versions, especially for Xperia Z3 and Z2 devices on Windows 8/10.
3. Partition Exclusion Toggle: A highly requested feature—checkboxes for excluding TA (Trim Area), system, boot, or userdata became fully functional. This allowed advanced users to flash only the kernel or modem without wiping their internal storage.
4. Root with Recovery Injection: For Lollipop devices with locked bootloaders, 0.9.18 offered an automated "Root" button that would downgrade security patches, push SuperSU, and install a pre-hacked dual recovery (Nut’s XZDualRecovery).
5. Backup TA Partition: The ability to back up the critical Trim Area (containing DRM keys for camera enhancements, Bravia Engine, and ClearAudio+) was fully stable. To this day, many users revert to 0.9.18 specifically for TA backups.

The "Bundle" Process

A signature feature of 0.9.18 was the Bundler. Users could manually select individual .sin files (system.sin, kernel.sin, userdata.sin, etc.) and bundle them into a single .ftf file. This allowed community members to create custom ROM packages that retained Sony’s proprietary partition layout—a feature lost in later versions that moved toward raw sparse images.
