   d) paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool
   
   e) open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important – if you do not want to delete any data of your phone,


3. just uncheck flashing userdata.sin file.
   All data will remain in your phone, but sometimes it can cause
   additional troubles. So it is better (and I recommend that) to do the
   backup of your personal data,


4. than proceed with clean instalation and then restore your personal data.
   
   f) turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button http://galaxymediaone.blogspot.com/
