Hello,
had the same problem with bend pins.
Thanks to Jodokast96 for nice and helpful photos and tips.
Unlike Jodokast96, I HAD to open the pin housing, and will post some photos and tips.
Regarding step 3 from Jodokast96, it is not necessary to remove the plate.
In step 6 I chose not to remove it, only the two screws and then you have the pin housing in your hand and can operate freely with it.
The springs don't pop out, but be very careful no to loose any, you won't find this tiny springs. If you remove the orange which is attached with adhesive tape, you will see this: forum1.jpg
Now you have access to the springs and pins and can repair that.
See pic forum4.jpg and forum5.jpg with the pins still inside and only the springs removed.
Then you can attach the orange plate back. I used Tesa adhesive tape, double sided. This is a adhesive tape for photos to attach in an album, it is very strong (just like the original adhesive tape I removed), is quite thin and double-sided and should be easily available in shops.
In forum3.jpg you see how I used the adhesive.
In pic forum2.jpg the pin housing is re-attached
That's it, I hope this will help you. I repaired my BG and I'm very happy
