SysCfg
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 AppleInternal firmware 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.
