Attempting to force a serial number change through unofficial software carries heavy risks:
Every iPhone has a unique serial number burned into multiple chips on the logic board. This number tells Apple’s servers everything: iphone serial number change
Early iPhones allowed rewriting the NAND’s copy via specialized software (e.g., MagicCFG, PurpleRestore). However, Apple introduced and A11+ authentication that cross-checks the serial between NAND and NOR. If they don’t match, the device enters a panic loop (constant reboot or Recovery Mode).

The serial number only "changes" when the device’s internal logic board is replaced by an Apple Authorized Service Provider . In this case, you are essentially getting a new piece of hardware with its own pre-assigned identifier. If they don’t match, the device enters a
