FP3+ does not react to anything after taking apart and reassembling

I can’t help you, because I don’t understand these things. But I leave you this photo, for reference: a year ago I cleaned the ones on my FP3 and since then I have used it daily without any problems.

The truth is that the cotton swabs came out quite stained, and although I scraped some plastic around the contacts, I imagine that is not a problem. Now the contacts shine quite a bit brighter than before, as you can see in the picture:

Best of luck
