This is a Guide to install firmwares on Xperia™Smartphones
Flashing your mobile is at your own risk. Sony would be in no way responsible for any damage.
Before Flashing:If you're on original firmware ( that came with the mobile ) then dial *#*#7378423#*#* in dialer > service info > software info > take a screenshot and keep the screenshot safe for future use
Optional : if you would like to backup your current firmware, then follow the first post below by 100rabh791
