Smaller repair companies will have the option of soldering the old chip off the cable and relocating the new one, but this is not a risk-free operation and due to the many small connectors you have to work very precisely, it seems almost impossible with a manual soldering iron. A very similar thing happened last year with the iPhone 12 series camera, in this regard we also wrote an article then involving one of the key players in the domestic repair industry, but in the meantime, Apple has backed out of the complete limitation of the unencrypted camera module, and after an iOS update, these cameras were working, only throwing an error message at startup.
