I am having a real tough time unscrewing the screws despite having the right screwdriver. It is like they are stuck on.

hello, I replaced the sensor but once I connect the flex cable to the motherboard it just doesn't work.
meaning that the sensor is not working (even no green light on the back) but the wireless charging is working.
I tried to disconnect and reconnect again but still no way to let the sensore work.
is there anything that must be reset softwarewise in order the watch can recognize the sensor?
Or probably the flex cable is not working properly?
thanks in advance
