      To be precise, my G5s has the touch blocked because I installed the stock rom for G4S v2. I would not want the problem of non-functioning of this rom is due to this.

    This rom fixes a problem with the calibration of the screen. For example, after installing official results KK and return to 4.2 or any other situation when the screen was out of calibration. 
    Mend should ONLY SP Fash Tool 
    Check that the chip has been properly recognized (see picture ID – last)

    Flashed with SP Tools the Jiayupolska original G5S Rom and after that, your fixed rom. Still the same touchscreen problem. My screen is auo45 type. The bottom half of screen is moved to upper part of the screen, this is the simptom of my decalibrated touchscreen. I tried G4S and G5S many roms withdowt luck.

    I have fixed my G5s …. But only with an new Display it seems possible. I changed the complete Display. Be Carefully at dismount because the Antenna Connection is al little dificult.

      So there is no other software solution for this problem. Beautifull. It seems that jiayu knew when he give us the kitkat corupted.

    NOTE 1 
    to all who have a problem with inoperative screens after installing the software is not for JIAYU G5S 

    This ROM ONLY fixes a problem with the touch screen after installation Oficial ROM 4.4 and back to 4.2 
    ROM has the same firmware which is 4.4 

    NOTE 2 

    On the Polish side JIAYU ROMs are only having old firmware touch screen
