Finally to tidy up the case

The adhesive strip (double sided tape) used to attach the old display probably did not come off with the display

Use the iOpener to loosen the adhesive

Use the picks to lift up the edges and then peel the strip off the case

This may again take several attempts with heating and picking, be patient, the slower you go the larger the strip you should be able to lift which should make it easier to take the whole thing off in one (or 3) goes
