Thanks for the great and accerssible guide. Having repaired a few iPhone 5's, this was really easy to get into. However I do have one perssisting problem.
I bought an iPhone 6 replacement screen assembly from the eustore. When assembling everything, I found that the home button connector cable on the bottom of the display unit (step 25) is too long in my replacement part. Thus, it overlaps with the little circuit board part of the home button cable, so the metal bracket does not fit too well when reassembled. This causes the home button to bea little loose, so it can't be fastened in a flush position with the display glass. This bothers me so much that I disassembled everything again, to try and change the position of the wires, without finding a satisfying solution. Is this a known problem with the display assembly?
