The Ultimate Guide to TC58NC6623 & SSS6698-BA MPTOOL: Unbricking, Formatting, and Low-Level Repair

7. Alternative Tools (Community Forks)

  • SSS USB Flash Tool (v2.0.3.6 for 6698): Unofficial GUI wrapper with simplified NAND database.
  • ChipGenius (read-only): Identifies the correct MPTool version needed by reading the USB VID/PID and firmware string.
  • nsiso (Linux): Open-source attempt to reverse engineer the ISP protocol. Supports reading firmware but not writing.

Part 7: A Word on Data Recovery

Stop. Before you run the MPTOOL, understand this: The MPTOOL will 100% erase all user data.

If the drive contains critical files:

  • Do not run MPTOOL.
  • Try software recovery first (Recuva, DMDE, R-Studio) – but if the drive shows 0MB, software cannot help.
  • For professional recovery, you would need a PC-3000 Flash with a VNAND probe (costing $10,000+). For a $15 USB stick, it is not economical.

Backup your data next time.

The Deep Technical Workflow (How to Actually Succeed)

Generic tutorials fail here. Follow this exact procedure: tc58nc6623 sss6698-ba mptool

Step 1: Force the Tool to Ignore the Toshiba Name

  • Open the MPTool folder.
  • Edit default.ini or SM3268AB.INI (depending on the tool).
  • Find [DEVICE] or [USB] section.
  • Add or modify: Vendor_Name="USB_Flash_Disk" and Product_Rev="1100" – this overrides the Toshiba readout.

Step 2: Manually Set the Controller Type

  • In the tool GUI, click "Setting" (password is usually 320 or 1111).
  • Under "Controller," uncheck "Auto Detect".
  • Manually select: SM3268AB (NOT SSS6698).
  • Under "Flash Type," do not auto detect. Find your NAND ID (use ChipGenius in Windows to read the 6-byte NAND ID). Then manually select that exact flash from the dropdown.

Step 3: The Critical ISP Selection

  • In the settings, go to "ISP" tab.
  • Uncheck "Auto Detect ISP".
  • Browse and manually select:
    • ISP_SM3268BA.BIN (for normal mode)
    • ISP_SM3268BA_SA.BIN (for SD/MMC mode, if your NAND is from an SD card – common in counterfeit drives)
  • Set "USB Power Mode" to 100mA (not 500mA). The BA chip has a weak internal regulator.

Step 4: Force Erase All Blocks

  • In the settings, check "Erase All Blocks" and "Erase Good Block Only = NO".
  • Check "Low Level Format".
  • Uncheck "Preserve Bad Block Map" (you want to rebuild it from scratch).

Step 5: The Dual-Channel Trap The SSS6698-BA pretends to be dual-channel but often has only one data line connected on cheap PCBs. In the tool settings, force "Channel = 1" (Single channel). If you leave it on "Auto" or "2," the tool will hang at Pretest 3% or Check ISP 50%.

Known Working Versions (by reputation in recovery forums)

  • MPTool S9 v2.1.30 – Works for early Toshiba TLC (15nm).
  • MPTool S9 v2.3.81 – Supports wider NAND IDs.
  • MPTool S9 v5.2.15 – Supports newer BiCS3 flash.
  • UFD_MPTool_S9_v2.3.86 – A stable build for 6698-BA.

Where to download? Because these tools are proprietary and often flagged by antivirus (they contain low-level driver injection), they are not on official app stores. You will find them on: The Ultimate Guide to TC58NC6623 & SSS6698-BA MPTOOL:

  • USBDev.ru (Russian forum – reliable source)
  • FlashBoot.ru (International tools database)
  • USBDongle.com

Warning: 99% of MPTOOLs trigger heuristic antivirus alerts. They are not viruses, but they contain ring-0 drivers. Run them only in a sandboxed VM or on an offline machine.

2.2 Identifying Your NAND Flash (Crucial Step)

The MPTOOL must match your NAND chip. Near the TC58NC6623, you will find another chip or a marked IC. Common NAND IDs paired with this controller:

  • Toshiba TC58TEG6DDKTA00
  • SanDisk SDTNQGBMA-016G
  • Kioxia TH58TFT0DFLBA4H

You will need the NAND ID (e.g., 0x98, 0xDE, 0x94, 0x93) for manual configuration. SSS USB Flash Tool (v2

Step 1: Identify the Drive

Plug the defective USB drive into your computer. Open ChipGenius.

  • Verify the Controller Vendor is Solid State System (SSS) or Toshiba.
  • Verify the Controller Part-Number is SSS6698 or TC58NC6623.
  • Note the VID (Vendor ID) and PID (Product ID).

B. Supported Operations

The MPTool allows the following low-level functions:

  1. Low-Level Format (LLF): Erases the FTL (Flash Translation Layer) and resets the NAND mapping table.
  2. Bad Block Management: Scans the NAND die, marks factory bad blocks, and creates a new block pool.
  3. Firmware Flashing (ISP): Loads the Interrupt Service Program (Loader) and Main Code into the controller’s SRAM and NAND-resident firmware zone.
  4. CID Modification (Card Identification): Rewrites the USB descriptor (vendor ID, product ID, serial number, power draw).
  5. LED Behavior Configuration: Adjusts activity LED blink patterns.
