I've just soldered a few cables wrong on a perfboard: I counted pins as if I was on the right side, while I was working on the reverse side.
Since the cables were between sockets, and in a somewhat symmetrical shape, I've found that if I shift the boards that plug into them a bit, the connections are right.
The problem is: 3.3V and GND are in purple, and the data cables are red and black.
Some part of me is screaming “NOOOOOO, REDO THEM. NOW!”. Another, just as important, part of me is going “meh, it works, call it done”.

Personally I would redo them to remove the cognitive load of remembering to not trust colors in that specific board... since I will, for sure, forget it.

in reply to Daniele Tricoli • •@Daniele Tricoli in theory, this is just a temporary thing (i.e. something that will remain as is on a shelf somewhere for a few years, with the only interaction being recharging the battery now and then), so it shouldn't be a big problem.
Also, the things that go into it have clearly marked pins.
But still, cognitive load.
