MagicCFG was based on the Purple tool by @1nsane_dev and uses the serial port of the iDevice to read and write to sysCFG on the NAND chip. With the upcoming updates we will include our Diagitizer DBU, which has the same power but is completly written in Swift for a even better compability inside the App.
MagicCFG can easily create a backup of the syscfg and flash them to new NAND chips.
Next to repairs, it's the most easiest way to upgrade your Storage (f.e. from 16GB to 128GB). You don't need the expensive NAND chip readers from far east to proceed. Only desolder the existing chip, replace with a bigger one which just need to be soldered on the motherboard. Then you can do everything else with MagicCFG
Next to the repair features, there is even more to discover. Changing color of the bootscreen from black to white, unlock your WiFi iPad from iCloud and lot more functions will be added with every update.
MagicCFG is a free software and will be most likely free forever, but development is very time consuming
and test devices and other development-related things are expensive.
I'm still a student and have to study a lot but I love to spend my freetime for the development of MagicCFG and other cool apps.
If you like my work, I would be really thankful if you can support me with some bucks...
