How to be sure of Apple genuine parts - "Unknown part" warning possible to circumvent
When purchasing refurbished iPhones, one would like to be sure all the parts are original (or replaced with genuine parts).
I'm seeing on YouTube that it's possible to circumvent these non-genuine part warnings by transplanting an 'IC' chip. Just search for "Unknown part warning iPhone" on YouTube and you'll get instruction videos on how to suppress the unknown part warning.
How do I know for sure that a 'refurbished' iPhone has genuine Apple parts?
