I assume the reflowing solder in the oven trick doesn’t reliably work anymore in the era of the high temp solders that are common in laptop manufacturing these days. Bringing the whole board up to flow temp in something as crude as a home oven is almost certainly going to fuck something else on the board.

I recall trying to do a laptop repair with dinky little soldering iron I got at the hardware store and it could not melt a single thing on the board I touched it to. Definitely not a faulty iron because I used it to successfully solder other things. This was at least five years ago. If that little toy couldn’t do it, then the entire board would need to exceed that temp in an oven, which is probably a bad idea since the iron was still managing to visibly scorch things despite not melting any solder.

Invest in a proper heat gun and learn how to use it, or just give up and give it to someone else who has one, imo.
