No charging or data connection
Got an iPhone 5 in where the customer had attempted to change the power/volume flex. In so doing he's done something to the lightning connector as it won't charge or connect for sync.
I've changed out the lightning connector assembly and replaced with a new one, no change at all. Had a close look at everything and can't see any damage. Tried two new lightning connector assemblies now so pretty confident it isn't that part.
It's odd as he's actually managed to replace the power/volume flex properly, but I'm at a loss as to what he's done to cause this issue. Any ideas what it might be that is broken?
