The most difficulty part is the Sticker

Mein Problem

the sticker snaped

Meine Reparatur

Everything of the repair is great, but only when I try to remove the stickers between the old battery and the rear case. The sticker is easy to snap. At last, I have to warm up the case and roughly tip it up.
