Unhappy [Q] Wiko Iggy touch screen inverted after flash!

Hi, I have a wiko iggy. After making a backup using Mtk Droid Tools 2.5.3, i tried to install another rom but with no results. Then I tryed to flash the backup I had made but everthing works exept the touch screen that seems to work with the axis inverted. My brother has a wiko iggy too, but even if i make the backup of his phone and flash it on mine I have the same problem. I tryed to make the backup ever with Sp flash tools but It has the same problem. Any Ideas?
