The former battery in my Jolla Tablet had done its job and need to be replaced.

Looking at the first in this thread I've brought the same battery: https://together.jolla.com/question/...y-replacement/ and are planning to replace it.

However I don't really know how to swap the pins on the new battery without damaging the black plastic plug.

I really don't know how to do it "using a flat precision tool screwdriver" as described in the thread without destroying the black plastic port.

Anyone in there who have any ideas?

Thanks in advance
