Hello, thank you for the rom

I installed the rom on my
BQ U Plus according the instructions, but I have one problem. My system and touch is upside down and reverse right-left.
I googled and found some solutions like changing ro.sf.hwrotation to 180 or 0 in system folder/build.prop ..but there is no such text in the file. I also tryed adding the whole line but it didnt help.
I would appreciate a bit help here please. A lot of info about this rom is in spanish, and I dont know the language so Its a bit hard for me to look for help. Thank you.
