Lightbulb [Q] SGS2 screen not working well with SGS2+, drivers?

Hi, i had a S2 with broken main bord and a s2+ with a broken screen, so i put the s2+ mainbord in the the s2, it almost worked out.

The trouble i have is that the touch screen doesnt register where i press correct. Its quit accurate at the top of the screen, but the further down the screen you go the more off you get. For example if you dail, if you press 5 you get an 8. Its also a bit off to the right.

I have searched for programs that calibrates the screen, but found none that does the job.

Anyone have an idea whats wrong and how to fix it?

Im thinking that perhaps if you just find the drivers for the s2 screen and install them somehow it will do the job? Can that be done with reasonable effort?
