Once you have the tool, here is the generic workflow:
| Problem | Solution |
|---------|----------|
| Tool sees 0MB / Bad Block > 100% | NAND ID mismatch – correct FlashList.dat or use forced ID via uDiskToolBar |
| Error: "Download ISP Fail" | Wrong ISP version – try ISP from SM3268AB_TC58NC6623 pack |
| Error: "Compare Fail at 0xXXX" | Bad NAND (replace chip) or poor soldering |
| Drive not detected after short | Use USB 2.0 port; remove battery from laptop; try different short point (D-/D+ to VSS) |
| MPTool crashes on Win10 | Run in Windows 7 compatibility + Administrator |
Before you download any software, you need to know which Flash ID your drive uses. The MP Tool needs this to load the correct low-level firmware (ISP).
How to check:
Note: If your drive isn't detected at all, it is likely in "ROM Mode." The MP Tool can still see it, even if Windows cannot.
First, a critical revelation: The TC58NC6623 is not a standalone controller. In 99% of cases, this string appears in tools like ChipGenius or USBDeview when the USB drive uses a Silicon Motion (SMI) controller, specifically the SSS6698-BA.
Why the confusion? TC58NC6623 was originally a Toshiba (now Kioxia) part number for an early USB 3.0 controller. However, SMI licensed, cloned, or rebranded this design. When you see "TC58NC6623" in Windows, the actual silicon underneath is almost always an SMI SSS6698-BA.
To perform successful "MPTOOL work," you must target the SSS6698-BA using SMI’s toolset. Using generic USB tools will fail.
The Scenario: The Invisible Drive It starts with a sinking feeling. You plug in your flash drive—perhaps a popular ADATA, Silicon Power, or Transcend model—and nothing happens. Windows plays the "device connected" chime, but no drive letter appears. When you check Disk Management or Device Manager, you don’t see a storage device; you see a generic, stubborn entry: "SSS6698BA" or a generic USB device.
For many, this signals the end of the drive. But for those who know where to look, it is simply a software coma. The controller is alive, but the firmware has lost its mind. Here is how the TC58NC6623 MPTool brings it back to life.
The Diagnosis: What is the SSS6698BA? The "SSS6698BA" is not a virus; it is the heartbeat of your drive. This is the SC6698BA controller chip, often manufactured by SSS (Solid State System). It is frequently paired with NAND flash memory like the Toshiba TC58NC6623.
When a drive enters this "demo mode" or "boot mode," it means the controller can no longer read the firmware configuration stored on the flash memory. This usually happens due to:
Because the firmware is corrupt, the controller halts the boot process and identifies itself as "SSS6698BA" to the host computer, essentially shouting, "I need a software reload!"
The Solution: The MPTool Workflow MPTool (Mass Production Tool) is the factory-grade software used to program these controllers at the manufacturing level. Using it is the only way to rewrite the firmware and partition table, effectively factory-resetting the drive’s brain.
Step 1: Identification (ChipGenius) Before you can fix it, you must confirm the hardware. You need a tool called ChipGenius.
Step 2: Sourcing the Software You cannot use just any MPTool. You need the specific version tailored for the SSS6698/SC6698 controller.
Step 3: The Critical Configuration This is where most users fail. Simply opening the tool isn't enough; you must configure the "Settings" or "Edit Config" menu to match your specific memory type (TC58NC6623).
Step 4: The Repair Process
The Caveat: The Data Trade-Off It is vital to understand the nature of the MPTool repair. This process is destructive.
When you run the MPTool, you will lose all existing data on the drive. The file system is wiped clean. This is a solution for reviving the hardware, not for forensic data recovery. If the data on the TC58NC6623 chip is critical, do not use MPTool; send the drive to a professional data recovery service.
Conclusion The combination of the TC58NC6623 memory and SSS6698BA controller is a workhorse configuration in the budget flash drive market. When it fails, it fails loudly, leaving users with a confusing "SSS6698BA" device ID. However, with the right MPTool and a bit of patience, a drive destined for the trash can be returned to full functionality, proving that sometimes, the hardware is fine—it just needs a new set of instructions.

The identifiers TC58NC6623 and SSS6698BA refer to specific components used in USB flash drives, primarily those manufactured by Solid State System (SSS). These components are often found in "no-name" or promotional USB drives, as well as some Kingston models. Component Breakdown
SSS6698 (BA): This is the USB Controller chip. It acts as the "brain" of the flash drive, managing data transfer between the USB port and the internal memory.
TC58NC6623: This is often the internal Toshiba or OEM part number for the same or a very similar controller (as Solid State System frequently collaborates with Toshiba).
MPTool: This stands for Mass Production Tool. It is a low-level software utility used at the factory to format, partition, and "burn" firmware into the controller chip. Why You Might Need This
People typically search for these terms when a USB drive is "bricked" or malfunctioning in specific ways:
"Disk is Write Protected": Even when there is no physical switch.
"Please Insert Disk": The drive is detected by the PC, but the storage is inaccessible.
Wrong Capacity: The drive shows 0MB or a capacity much lower than its original size. How the MPTool Works
The SSS6698 MPTool works by re-initializing the controller and "re-mapping" the NAND flash memory. Here is the general workflow:
Identification: You must use a tool like ChipGenius or Flash Drive Information Extractor to confirm the controller is indeed an SSS6698/TC58NC6623.
Matching Firmware: The MPTool requires a specific "ISP" (In-System Programming) file that matches your specific NAND memory chip (e.g., Toshiba, Hynix, or Samsung).
Flashing: You run the utility (often named 3S_USB_MP_Utility or similar), which clears the old settings and writes new firmware to the controller. ⚠️ Critical Warning
Using an MPTool is a destructive process. It will completely erase all data on the drive. Furthermore, if you use the wrong firmware version or settings, you can permanently disable the USB drive (hard brick). SSS Flash Controller Restoration Tools | PDF - Scribd

Troubleshooting and Repairing TC58NC6623 / SSS6698-BA Flash Drives
If you are dealing with a corrupted Toshiba or Kingston USB drive that shows as "No Media," "Write Protected," or is simply not recognized, you likely have a device using the TC58NC6623 (Solid State System SSS6698-BA) controller. Restoring these drives requires a specific Mass Production Tool (MPTool) to reflash the firmware and reconfigure the NAND memory. Understanding the TC58NC6623 / SSS6698-BA Controller
The TC58NC6623 is a rebranding of the SSS6698-BA controller manufactured by Solid State System (3S). It is commonly found in: Toshiba TransMemory series (8GB, 16GB, and 32GB models). Kingston DataTraveler 2.0 drives.
These controllers are notoriously difficult to repair because official manufacturing utilities are rare and often lack the specific binary (.BIN) files needed for different NAND flash types. Step 1: Confirm Your Controller with ChipGenius
Before downloading any software, verify that your drive actually uses this chip. Download and run the ChipGenius utility. Plug in your USB drive.
Look for the Controller Part-Number. It should explicitly state TC58NC6623 or SSS6698-BA.
Note the Flash ID (e.g., 98DE98927250). This ID is critical for choosing the right firmware binary later. Step 2: Choosing the Right MPTool
Finding a working tool for the SSS6698-BA is a challenge. Experts suggest trying these specific utilities:
3S USB Mass Production Utility (ver 3.287): This is the only version widely reported to support the SSS6698-BA chip family. However, it may only include a single generic binary file that might not match your specific flash memory.
Toshiba TransMemory Secure Utility: Interestingly, this official Toshiba tool has been known to work for basic restoration on SSS6698-based drives.
Alternative Tools: If the above fail, some users have had success with older SSS6691 or SSS6690 utilities, though this is less reliable. Step 3: The Flashing Process (General Guide) Start: Go back to the main screen and click "Start (Space)
Preparation: Use a 32-bit version of Windows if possible, as these older tools often have driver conflicts on 64-bit systems.
Launch the Tool: Open the SSS_MPTool.exe (or similar) before inserting the flash drive.
Configuration: Click on Setup or Settings. If prompted for a password, try common defaults like 320 or simply leave it blank.
Select INI and BIN: You must choose a configuration file (.INI) and a firmware file (.BIN) that matches your Flash ID. If your exact ID isn't listed, the tool will likely fail with an "ISP Code Not Found" error.
Start: Once the drive is detected, click Start. The tool will erase the NAND, check for bad blocks, and attempt to rewrite the firmware. Common Risks and Limitations
The TC58NC6623 is a rebadged version of the Solid State System (SSS) 6698-BA controller, commonly found in Toshiba flash drives like the TransMemory series. Repairing these drives often requires an MPTool (Mass Production Tool), which can re-flash corrupted firmware and isolate bad NAND blocks. Controller Identification
Before using any repair utility, verify your hardware specifications. Tools like ChipGenius are essential for extracting the precise VID/PID and controller model. Controller Model: TC58NC6623 / SSS6698-BA Common NAND: Typically Toshiba TLC

Standard restoration tools for SSS controllers are often available on technical repositories such as FlashBoot.ru or USBDev.ru.
3S MP Utility (various versions): Primary tool for flashing the controller.
SSS6690 USB Flash Sorting: Often used for initial "sorting" to identify and map out bad sectors before final flashing.
U3S SafeEraseUtility: Useful for completely erasing existing firmware blocks to return the drive to a "Generic" state. General Repair Workflow
Using MPTools is a destructive process that permanently erases all data on the drive.
Preparation: Disable antivirus software temporarily, as these tools are frequently flagged as false positives. Configuration:
Open the MPTool and navigate to the settings/configuration page.
Some versions may require a password to unlock advanced settings (standard passwords often include 55 or are blank).
Mapping: Use the "Sorting" feature to scan the NAND for bad blocks.
Flashing: Select the appropriate firmware binary for the TC58NC6623/SSS6698-BA and click Start.
Validation: Once complete, the drive should be recognized by Windows and may require a final format via Disk Management. Alternatives for Minor Corruption
If the drive is still recognized but unreadable, try non-destructive methods before flashing:
Error Checking: Use the Windows "Check" tool under drive Properties.
Third-Party Recovery: If data recovery is the goal, software like DiskGenius or Disk Drill can sometimes bypass logical corruption without re-flashing.
If you'd like to proceed with a repair, tell me the VID and PID numbers found by ChipGenius so I can help you find the exact firmware version needed.
