Ok that is different than this:Sounds like you have a restriction.
Plunge the toilet or remove the toilet entirely and see if there's any clog, if not snake it while the toilet is off.
As well make sure there's nothing stuck in the bowl, which is a common issue if you're having problems.
And once you did that, check the tank to make sure enough water is filling up to flush the bowl. If you don't have enough water in the tank you won't get a complete flush.
The flapper can be bad and cause the tank to be half empty, or the float can be in the wrong position causing the tank not to fill in it's entirety.
Not much more to the toilet not working.
Is the water supply on all the way? Any block in the water line coming to the tank?
Or post a video like CV requested and I'm sure someone will be able to be of help.
@CountValentine So far your 1/3 with your video request's.
