Repairing ipod 4 with sentimental value.
The device had been dropped, breaking the display/digitizer. The iPod has sentimental value so the owner asked me to attempt to repair it.
I broke the first digitizer because I hadn't thoroughly cleaned the area where the glass sits. The second attempt was better and I got it together without too much problem.
Make sure the digitizer cable is correctly folded back on itself otherwise it will interfere with the display seating correctly. Use enough stickum on the edges where the display assembly sits. Be very careful and don't force anything.
