My speakers stop working on my iPhone 4S. I tried various noninvasive recommended solutions to fix the problem - none worked. I then knew the speakers had to be replaced. I came across an iFixit Guide. After reviewing the guide, which seemed clear and uncomplicated, I order the speaker part plus the Pro Tech Toolkit.
Once I received my order, I sat down with iFixit Guide in hand and within 2 hours I was finished with the repair. Why so long? Well, I have Parkinson's, which slows me down due to the shakes I get (those tiny little screws can be challenging). And I had a tough time in reconnecting to the logic board - the alignment was tight. The Pro Tech Toolkit was a project saver - having the right tools was critical to completing this repair. Thank you iFixit
The Guide is very helpful...review it through and be mindful of how you layout the parts for reassembly. I struggled to reattach the logic board connector. Maybe there's an easier way to do it when it comes to aligning up the connectors? However, make sure you have a good light source to shine upon this connector when reattaching - it is certainly helpful to see what your attempting.
