This was super tight to get the two golden contact things off. Took me aprox 20 mins. Have to be patient with this one. The instructions are golden.
Be careful taking the front panel off. I tried to pull it very careful but it ripped. One of the cables was damaged but luckily, it was the cable that goes out with the old front panel. It also ripped 4.1 mm Phillips screw from step 13 and it jumped to the floor. I was lucky and recovered it from the floor.
In the end everything was fine and phone works great. But remember to be super careful.
