During the peak of the Sony Xperia lineup—specifically with devices like the Xperia Z series, the Xperia T, and the Xperia SP—manufacturers were moving toward locked bootloaders and proprietary file systems. Sony, however, maintained a unique relationship with the developer community.

This gap was bridged by Androxyde, the developer behind Flashtool.
