Flashtool (often stylized as "Flashtool") is a free, open-source Windows-based utility originally developed by Androxyde. It is designed specifically for flashing firmware (ROMs) onto Sony Ericsson and Sony Xperia devices. Unlike generic flashing tools, Flashtool respects Sony’s proprietary flashing protocol (S1 fastboot) and can handle .ftf bundle files—the standard firmware package format for Xperia phones.
