When reattaching this bracket make sure your Battery ribbon is already tucked underneath the battery with only the minimum clearance required. Then make sure the brackets overhang is over the battery ribbon. Dont try to slide it under the Ribbon.
Be Careful of a tiny metal piece attached to the black bit on top that acts as the screw spot for the blue screw. I just slid it back on. Hopefully no harm done.

I used tweezers. Worked great. Til i applied too much pressure and one of the washers went whizzing away into oblivion.
