I just want to know if theres an easy way to root xperia t2 51.1 like kingroot or something like that. If anyone can help me with my problem i will try to donate some money to you. 
It's working now...Kingroot doesn't work on 5.1 lollipop and is the last thing you should be using to root your phone. There is no root xploit for locked bootloader 5.1 you need to flash pre-rooted zip via recovery on rooted kk for LB, for unlocked bootloader devices root the usual way.
