[Q] Screen calibration on boot Lenovo A850

I dont know why my lenovo A850+ lost his screen calibration. There is a frame on the lower position of the screen (where the spacebar on the keyboard is) where don't detect the finger, i calibrated it whith a program and worked again, but powering off and powering on the phone makes the calibration get "lost".

Now i tried to reinstall the original rom and i get a "welcome screen" again, and i can not get out of there because i can not hit the "next" button.... so i'm stacked.

Some ideas or solutions?

Thank you for reading ans sorry for my english....:D
