SysCfg also known as System Configuration is a partition on the NAND found on iOS devices.

It stores the Serial Numbers and Calibrations of hardware of the device, and the Software Behaviour bits.

It is a dictionary-like structure with each entry having a 4-byte (32-bit) key (Ex: SrNm).

With an AppleInternal image called Diags, that is found on EVT / DVT / PVT devices, this data can be modified and reflashed.

A smart programmer may be able to use a jailbreak and write a controller around this partition to do the same.

Modifications to these numbers are permanent but have advantages too.

A Chinese iOS device generally has limitations as defined by the Software Behaviour bits and the Region, modifying these in the SysCfg may remove them.
