Replaced both cameras, power button and cable, and battery. Ditgitizer not working. Checked connectors three times. Screen and power button work fine. Thanks

You have damaged the digatizer cable most likely when you were removing the screen and tilted the screen to high.. Even a 90 degree angle is to much I find it needs to be less of an angle

I have the same issue , after battery replacement the digitizer is not working. I tried with a new front panel. (digitizer +LCD) the new one also doesn’t work. What could be the problem ?
