I completely disassembled the keyboard and replaced the plastic rivets with micro screws. I cleaned all the various layers of film that make up the keyboard and restored the damaged tracks with a conductive marker. It worked well. I guess the 48 has the same construction philosophy. Find details in the forum if you search my posts.

Thank you for the suggestions.

I am saving the "take it apart" as a last resort in case everything else fails!

So far, with alchool + contact clearner + silica gel, it seems to be getting much better.
I got past the boot loop, and most keys are working perfectly. Only one key is failing but if I press it hard enough it works.

I will test it for a few more days, because I just took it off from the silica gel, not sure if I leave it out for long enough humidity could pick up again and start showing issues.

Only time will tell.
