The delivered material is totally OK, especially the glass and the mold, where one does not need a part of the tool. In the package is a link, as it should be. The video, which you can then watch shows how to disassemble the whole thing, but not how to change the glass. For this, I have to deduct a star. On the Internet there are many other helpful videos where you can see how the dismantling of the old disc with the hair dryer and a knife done that. I recommend a couple of tweezers handy to have. Because the display was highly fragmented in my case, which has removed and cleaned lasted a good two hours. One should have acetone, alcohol and lint-free cloth to hand. To insert the new disk must use the adhesive pad mitglieferten. Here is the upside down 3 included. Unfortunately, the pad is very special punched, and is still missing precise instructions which steps you subtract what, and how aufklebt. Caution, the central adhesive part belongs away otherwise you kleebt the LCD to, and stick the lateral webs for the disc are very very thin. I have the first adhesive ruined, but by roughly understood as it could go. In the second, I was successful. Two top Mechainker tweezers were a great help. After the glue sticks like hell on his fingers. I have applied from the top down the pad, then corrects the margins with the tweezers. I can only recommend a lot of patience here. If it is then sitting, stick the disk, and connect securely to the hair dryer. I was overjoyed when really everything went back to the turn. If time does not matter, you have a steady hand, something Feinmechaniker tool and craft experience, you can inexpensively save his phone.
