I have been having problems with the latest firmware version of xperia J - 11.2.A.0.31. The version is way too slow, slower than my older version. It even takes time to completely display my home and menu screen. So I want to downgrade the firmware 11.2.A.0.31 to 11.2.A.0.21 (my previous version). I would wish to get help as soon as possible.
