Chosen Solution
I decided replace lightning ports. Because old lightning ports f**ked up. But, that isn’t problem. Problem is Taptic Engine rounded screws are damaged, so i can’t remove Taptic Engine. Also, can’t replace Lightning port. Maybe I’m dumb - using cheep, crappy screwdrivers. So, anyway, That screws are damaged, I can’t replace parts anymore. :-(
Poor quality screwdrivers can damage the screws. You could look at the iFixit Store to find decent quality screwdrivers. As for the damaged screws, you could try to use super glue to stick the screwdriver to the screws. Other people like to put a thin rubber band (elastic) between the screwdriver and screw. Of course, you could try to grind a slot with a small Dremel-like tool but that is risky considering the component density in the iPhone. You could also try to use a screw extractor like this.
