OK, try the straight forward resolder first. Just scrape the coating off the pins and heat them to melt the solder. It would not hurt to add a little more solder, but may not be necessary. I used a 20Watt iron to get enough heat. In my case that was not enough, maybe a contamination problem, but others have not reported a problem as long as they used enough heat.
Paste flux contains tin or zinc chloride and is used when soldering copper pipe. It's acidic and not recommended for circuit boards. The q-tips were used to clean any acid off the pins. It's best if you not use it.

 

Just a thought, if you can expose then locate the wires/ connections to be soldered, just find someone to do the soldering.
It ain't easy with no experience.
An electronic repair shop (computers) or even a jewelry repair shop.
