All garage door openers have a quick release. Have you checked to make sure that is locked in place? Most have a cord hangin from it and you pull it which releases it from the chain. Make sure that is engaged and it should work.

If the main light flashes 10 times when the door stops it is a door sensor problem. Make sure the small light on each one is lit and not flickering. If the main light doesn't flash you have either a bad IR sensor which is a small printed circuit board just in front of the motor or you need to increase the down force which is a control on the rear of the motor unit.

You may have a bad wall control. Try disconnecting it from the opener and try. Otherwise it is time for a new model.

Remove the cover and check the drive gear. It is white nylon and is just in front of the motor. It may be stripped. Take a close look at those door springs. They can sometime appear to be okay when one is broken.

The only procedure I have ever followed is to press the learn button and then enter the code, and not do anything else. I think your last step of holding the button until the light goes out is clearing codes as fast as you enter them. Just stop after you enter your code and let the learn mode time out on its own. That should do it.

And don't put your head through the wall. It just causes more headaches.

wipe off the sensor glass with a isopro rubbing alcohol; it should fix it.

You have a stripped gear inside the opener
