Thanks for the comment! Yes, you can get away with not removing the battery, but you’ll need to be extra careful with that ribbon. I just didn’t want to introduce that risk of accidentally tugging (and potentially damaging) the ribbon, especially since it’s not in plain view unless the battery is removed.
I tried the rubberband method on a semi-stripped tri-wing screw, not expecting much. Wha’dya know, that did it!
The exact thing happened to me just now; I reinserted it at a (very slight) angle, and bent one of the pins at the end of the socket. Luckily, I was able to straighten it back up with a sewing needle. I made sure the spacing was consistent with the rest of the pins, and that I reinserted the connector as straight as I could, so it doesn’t happen again.
