Short summary:
Source Code Based on the Macbook developer j4nf4b3, which is in Swift, I only adapted the code to Windows and added what was necessary to make it work
Simple SysCFG Editor written in C#. Pure C#. Just the editor. To enter purple / diags mode
The app makes it possible to read, write and restore important configuration data on iDevices, making it an important tool for hobbyists and professional repair stores. It requires no accessories except for a DCSD cable / adapter and is therefore much cheaper and faster to use than with conventional NAND programmers from the Far East.
This tool is mostly written in C# and interacts with the syscfg partition of iDevices. So be careful in usage and make sure you understand what you are doing!
