Medium difficulty, seriously? I dismounted with great pain, everything is taped everywhere. When pulling on a piece, everything comes, one feels parts writhe under the force exerted ... In the end, the iPod is dismounted, I change the screen, I had trouble to replace the button with wire in the right place and I mounted everything again. After several hours trying to stall while the right place, I drop. The ipod is raised but the screen is raised compared to the original, the home button is functional but I have to press very hard on it for it to work and, above all, I damaged part of the LCD when disassembly, so my screen is new, but the LCD does not display properly all the information.
