Thanks, seems easy enough.
The only time my hatch wouldn't open was after rain/ice. I assume the rubber seal got water on it and froze, freezing the hatch to the rubber. Pushing the button didn't help, the spring wasn't strong enough to break the ice seal. I tried pounding down on the hatch with the heal of my hand but nothing, in the end I ended up slipping my fingers as much as possible in the crack and while lifting I used the remote hatch release(only found on '13 and later Leafs. If it had happened to my '12 it would have taken a second person, one to pry up on the hatch and one to pull the remote hatch release below the steering wheel. As I was alone I was glad it happened to my '13
Using the trick you posted even with a '12(or '11) it should be a one-man job.
