# open-ssd: reconstructing SM2263XT SSD initialization

> open-ssd reconstructs an initialization workflow for Silicon Motion SM2263-family SSDs. Its Python tool generates parameters, scans bad blocks, packages firmware and writes NAND system areas; accompanying documents map controller commands and JMS583 bridge passthrough behavior. The author identifies one tested SM2263XT, YMTC NAND and JMS583 combination.

## Requirements & limits

- **Prerequisites:** Python 3.10 or later is required; USB access additionally requires system libusb.
- **Prerequisites:** The user's own factory package and a supported SM2263XT, YMTC NAND and JMS583 setup are required for the documented opening procedure.
- **Testing evidence:** Opening erases and writes NAND; the revised MPInfo output has not yet undergone a native M.2 reflashing acceptance test.
- **License:** No licence file in the repository.
