Your bracket may look different to this. Mine had a black covering on the long edge being held between the fingers in this illustration. Same screws, same position, just a different color.
“Don't insert the opening pick any deeper than the black bezel on the side of the display. Inserting the pick too far may damage the LCD.”
Unfortunately, you only know you have inserted it too far when you have, and you start seeing little bubble veins form between the glass screen and the LCD.
The adhesive can be very stiff/hard, and if pushing through it can result in the pick plunging into the LCD when the adhesive finally gives way.
Take your time, use alot of heat, and if you need to try and push the pick in, try and do so in a slicing motion along the edge, use the wide edge, or hold the pick so that your finger will hit the edge of the screen before the pick tip will pass the bezel.
Good guide. Easy to follow. Adding heat to the back to loosen the adhesive is a _must_ though - I was lucky the Li-Ion battery didn't pop as I bent it prying it out with an old credit card in the end.
Shame iFixit don't ship batteries overseas - had to buy the parts & kit through eBay.
