EMMC Module (8GB/16GB) with Pre-installed Firmware
The Neptune 4 Plus architecture separates the printer's 'brain' into a Linux host and an MCU. Firmware corruption typically resides in the EMMC module's storage sectors where the Klipper service is hosted. Replacing the module with a factory-imaged unit resolves filesystem corruption and ensures version parity between the host and the hardware abstraction layer.

MKS SKIPR / Main Control Board
If flashing the EMMC does not restore communication, the failure likely exists in the MCU's bootloader or the serial communication bridge (UART/USB) on the mainboard. This hardware failure prevents the firmware from initializing the handshake regardless of software integrity.

USB Firmware Recovery Drive
A properly formatted FAT32 drive containing the specific update sequence (MCU .bin followed by Screen .tft) is required to resolve version mismatch. This addresses the logical failure where the printer hardware is functional but the software stack is out of sync.
