Tc58nc6623 Sss6698ba Mptool Fixed May 2026

Here’s a draft write-up for fixing the TC58NC6623 / SSS6698-BA controller using the correct MP Tool.

6. Post-Fix

• If Pass: Unplug USB, reinsert. Format in Windows as FAT32 or NTFS.
• If Fail: Try different MP Tool version or check Flash ID compatibility.

What is TC58NC6623?

• Manufacturer: Toshiba (now Kioxia)
• Type: 3D TLC (Triple-Level Cell) NAND Flash Memory
• Significance: This is the actual storage chip. The number TC58NC6623 indicates a specific density, voltage, and command protocol. Common variants include 64GB, 128GB, and 256GB capacities.

8. Conclusion

The TC58NC6623 + SSS6698-BA combination is recoverable using a SM3268AB-derived MPTOOL with a correctly configured flash database and ISP firmware. The critical steps are forcing proper NAND ID recognition, using TLC-optimized ECC (70 bits), and erasing all blocks before reprogramming. This method avoids the need for hardware programmers (e.g., EasyJTAG). However, due to the lack of an official MPTOOL for SSS6698-BA, users must adapt settings from a similar controller family — a common but risky practice. For high-reliability environments, replacing the drive is still recommended. tc58nc6623 sss6698ba mptool fixed

5.2 Detect Drive

• Click Scan USB (F5).
• Drive should appear with original capacity or 0MB.
• If not, re-short or change USB port.
