How do you remove this? I tried everything using power tools but it didn’t work. I used a flat head screw and the hammer didn’t work too what else can I do?

Well you WOULD use a bottom bracket socket tool but we’re into “angle grinder” territory here
You could take the bearing out, and use a large nut & bolt to tighten into it and use that to screw it out as it unscrews into the direction that the bolt tightens into.

This is for a fixed cup, but after you remove the bearing its basically the same.
The last thing i would do is take the bearing out, and saw carefully until it almost hit the threads. Cut it into sections and try to break it out in pieces.
But yeah, these bottom brackets suck so hard. I put modern BBs on all my builds, no more of this shit.
Rj has a few vids about stuck bottom brackets.
I’ve successfully used a hacksaw blade to cut 3 slices into a cup and then crushed it to remove it. It damaged the frame a little though
