Hi everyone,

I’m planning to replace the rear camera on an iPhone 13 Pro Max and I want to avoid triggering the non-genuine part notification. I've come across different methods and tools, and I need some advice on the best approach.

Here are my main questions:

1. Using V1S Pro for Data Transfer: I’ve seen that the V1S Pro can be used to read and write calibration data from the original camera to the replacement camera. Has anyone had success with this method? Are there any specific steps or precautions I should be aware of?

2. NAND Transfer Method: Some tutorials suggest physically transferring the NAND chip from the old camera to the new one. Is this necessary if I’m using the V1S Pro, or is it an additional safeguard? What are the advantages and potential risks of this approach?

3. Combining Both Methods: I’ve also seen instances where both methods are used—transferring the NAND and then using the V1S Pro to read and write data. Is this overkill, or does it provide a more reliable outcome? If you've done this, can you share your process and any tips?
