You can root the phone directly with no need for downgrading through this tool 'Eroot': 1- You need to have PC companion installed on your PC. 2- On your phone, Go to settings > Security > Mark 'Unknown sources' Settings > Developer options > Mark USB debugging Settings > Xperia > connectivity > USB connection mode > select MSC mode 3- After marking the settings above, connect your phone to PC ( Skip PC Companion installation on your phone ) and wait for the adb drivers to be installed. You might need to disable your anti virus before this step. 4- Now, run the Eroot tool downloaded above -it's in Chinese i guess- you will see it's doing some downloading and then a Root button appears.

And Baam, your phone is rooted. Look for the SuperUser app in ur apps pages. Also for further check you can use the Root Checker Basic app available on google play store. If it somehow fails for the first time, give it another go. Restart everything, your PC, phones etc. If it doesn't work at all, you might need to try the other method for rooting i.e: downgrade-root-upgrade.
