Flashtool

There are more official ways how to update firmware in your Sony (Ericsson) XPERIA smartphone. You can use XPERIA Companion or Over the air update. But sometimes it is better to use unofficial way – you can get latest firmware for your phone immediatelly without waiting.

This program was originally made to flash sin files downloaded by SEUS or PCC. You can download Flashtool 0.9.33.0 for Windows. And it’s available for Linux and MacOS too. This newest version also support Xperia 1 II, Xperia 10 II and Xperia 5 II.

Why should I use flashtool?
– once bootloader unlocked, official Sony tools do not work anymore
– using official Sony tools, you can only upgrade. No downgrade possible
– using Flashtool, you can choose what to flash and what not to flash
