Tried to fix a squeaky floor with construction adhesive and made it way worse

My upstairs hallway floor had one squeaky board, so I watched a video where a guy just drilled a hole and pumped in a whole tube of Liquid Nails subfloor adhesive. I did exactly that, using about $15 worth of the stuff. The squeak stopped for maybe two hours, then came back ten times louder, and now the board feels weirdly spongy when you step on it. I think the adhesive never really set right and just made a mess. Has anyone actually fixed a squeak this way, or did I just get terrible advice?

Watched the same kind of video last year for a squeaky stair. Ended up with a sticky, bouncy mess that felt like walking on a trampoline. I think the problem is that stuff needs air to dry, and pumping it into a sealed space just makes a wet pocket. Had to finally call someone who used proper screws from below. That adhesive is still in there, I guess, as a monument to my bad DIY skills.

Yeah that "wet pocket" thing is exactly right. I tried the glue injection too and it just never set right, stayed kinda gummy. What finally worked for me was getting under there with some trim head screws, the really skinny ones with the little heads. You gotta pull the carpet back a bit to find the joist but once you sink a few in, the squeak is gone for good. Way less messy than that glue stuff.
