• Sony Emma (Official) – Only for Sony-rebranded devices; does not support Ericsson legacy models.
• Omnius (Paid) – Professional unbricking tool for SEMC phones; supports more exotic chipsets.
• Androxide's Flashtool v0.9.33.2 – The final version that still includes "legacy mode" for X10/Arc. You can enable it via config.properties: legacy.device=true.

1. Download Flashtool (if not already) from the official source (e.g., Androxyde’s GitHub).
2. Install and run FlashTool.exe (as Administrator on Windows).
3. Select flash mode:
   • Lightning bolt icon → Flashmode (for full firmware).
   • Fastboot mode (for boot.img, recovery).
4. Load firmware (.ftf file) – place it in C:\Users\YourName\.flashTool\firmwares\
5. Connect device:
   • For Flashmode: Power off → Hold Volume Down → Connect USB.
   • For Fastboot: Power off → Hold Volume Up (or specific key) → Connect USB.
6. Select firmware from list and click Flash.
7. Wait for green "Flashing finished" message. Disconnect and reboot.

Chapter 1 – Introduction to Flashtool

Flashtool is a free, community-developed Windows application for flashing, unbricking, and maintaining Sony Ericsson / Sony Xperia Android devices. Unlike official tools (Emma, PC Companion), Flashtool works with bootloader-locked and unlocked devices, supports custom firmware bundles (FTF), and bypasses many signature checks.

Version 0.6.9.1 (circa 2012–2013) was a stable release during the Xperia 2011–2012 line (Xperia Arc, Neo, Play, Ray, S, P, U, Go, etc.). Many advanced users keep this version for compatibility with older Java environments and driver stability.
