: If you replace a faulty NAND chip, you must write the original device data (SN/WiFi/BT) back to the new chip for the device to activate.
: Unlike traditional methods that require a specialized "Purple" serial cable to write data to the NAND, this tool uses software exploits to enter the necessary diagnostic modes directly. : If you replace a faulty NAND chip,
: It boots a custom ramdisk or diagnostic image that opens the USB serial port for data writing. Using such tools generally voids warranties and should
Using such tools generally voids warranties and should only be performed by experienced technicians, as incorrect SysCfg data can lead to activation errors or "bricking" the software state of the device. : The device is first put into Device
: Allows for the changing of Serial Numbers, Bluetooth addresses, and Wi-Fi addresses, which is essential for repairing "Wi-Fi address mismatch" issues after a NAND replacement or for unlocking certain device restrictions.
: Specifically optimized for the iPhone 7, 7 Plus, 8, 8 Plus, and iPhone X.
: The device is first put into Device Firmware Update (DFU) mode.
