Hi Arturo, without looking at the device, I can only guess. But, if it doesn’t respond to any touch whatsoever, you might take a second look at the touchscreen component itself (that is the clear glass sheet, step 9, picture 3) and be sure you have that thing connected properly and there is no damage to that little ribbon cable itself. I’m not aware of any calibration procedure, but I could be wrong.
