Hi :)

You probably remember programs like SeTool or A2uploader? Free, fast and handy...

I present to you today S1Tool, another child of man named the_laser supporting all Xperia smartphones of the years 2010 to 2011 ;) In this tutorial I will show you what such a small program can do and how to use it.

Supported models

QSD8250: Xperia X10i, Xperia X10a, Xperia SO-01B.

MSM7227: W8 E16, Xperia X8 E15, Xperia X10, Xperia X10 mini E10, Xperia X10 mini pro U20.

MSM8255: active ST17, arc LT15, arc S LT18, mini ST15, mini pro SK17, neo MT15, neo V mt11, PLAY r800, pro MK16, ray ST18, Live with Walkman WT19.


1. Before 'playing' charge the battery ;)
2. It is good to backup your phone's data (I reccommend My Phone Explorer).
3. Install the latest flash drivers: http://www.sonyerics...e-flash-driver/
4a. Here you can download S1Tool: http://www.sonyerics...le/3406-s1tool/ and here the firmware http://www.sonyerics...droid-firmware/ (program supports .ftf and .sin_file_set extensions)
4b. Mind that .ftf files should be packed into two separate .zip files należy spakować do dwóch osobnych plików .zip according to the structure of .sin_file_set files or you should just use flashtool, here you can read the guide for it: http://www.sonyerics...da-flashtoolem/
5. Unless the program works properly set compatibility with Windows XP SP3.
