Default help. i cant acces language and input settings

Hi. I rooted my phone( Acer liquif e2) long time ago and i deleted swype keyboard if i remember well. And now i saw i can't open language and input settings and also i can't install customs keyboards from google play. Is there a way for me to acces that setting again? Cause i want to change my device language to english(romanian from factory).
P.S. i am kinda noob.
