Ahhhh...Well, I was rolling nude that day (no multi-tool)...seems that I coulda popped the effected links and rejoined them with the chain breaker...
What's the purpose of the quick links if you need a chain breaker to begin with? Seems like a quick link isn't necessary at all as long as you have the chain breaker...
I haven't got time right now for the full history lesson.
But, the chain tools predate quick links.
Used to be. Back in the olden days. In the before time. Link pins extended beyond the side plate and could be pressed in and out, more or less at will. Using one of those tools, like you have.
But, as the number of gears in the back incresed, the chains had to grow narrower. Rather than reduce the internal width, the external width was minimized. Resulting in less and less pin protrusion and ultimately pins that are peened in place. These pins can not be revomed and replaced without significant loss in link strength. They create little fissures in the sideplate when they are extracted.
To allow for the assembly of such chains two systems have been employed, quick links, and in the case of Shimano special hardened and slightly oversized "connecting pins".
So, the purpose of the chain tool in this day and age is to either break a link for the purposes of shortening a chain upon initial installation, insert a Shimano "connecting pin" into a chain that is being rejoined or in your case extract the remaining half link.
Whether you would be able to successfully remove a full link and temporarily rejoin the chain with one of the original peened pins I am not sure of. I suspect it would be very difficult to get the mushroomed end back into the opposite outerplate. Like wise, unlike the old style pins that would simply slide out of the inner half link, the peened pins sometimes (but not always) need to be extracted through the inner link. Hence my earlier comments about the use of whatever road side debris I could find to assit with this, in preparation for use of quick link. Fact is, I think the sideplate of my Rap6 multitool has a little slot in it that would probably provide adequate leverage. But, a nail and a reasonable rock would work just as well.
Keep at it, you learn and figure this stuff out. I've got a lot of years of true back country mountain biking and secondary road riding behind me.
