Insert your malfunctioning USB drive into a native USB 2.0 port (ideally on the rear panel of your motherboard to minimize power drops).

💡 : If the repair fails with a "FlashID not supported" error, you may need a newer version of the MPTool or a more recent FlashDB file for that specific memory chip.

Using a sewing needle or a fine-tipped pair of metal tweezers, carefully bridge (touch) two data pins together on the flash memory chip. Usually, pins 29 and 30 or pins 41 through 44 are the standard data lines.

: Select " Standard Scan " or " High Scan " to identify bad blocks. While "Factory Scan" might recover more space, "Standard Scan" is often more stable and passes verification tests like H2testw . Firstchip Yc2019

This is where the Yc2019 outshines simpler chargers. When USB is connected, the chip dynamically allocates current:

The (often identified as chipYC2019 or related to the FC1179 series) is a popular, cost-effective USB flash drive controller chip widely used in inexpensive and often counterfeit high-capacity USB drives, particularly those originating from Chinese manufacturers.

Firstchip Yc2019 is a state-of-the-art system-on-chip (SoC) designed by Firstchip, a leading technology company specializing in developing innovative semiconductor solutions. The Yc2019 SoC is a highly integrated chip that combines advanced processing, memory, and interface capabilities, enabling a wide range of applications across various industries. Insert your malfunctioning USB drive into a native USB 2

This indicates a hardware-level disconnection. Clean the USB contacts with isopropyl alcohol. If that fails, you must use the physical detailed in Step 2 to bypass the corrupted memory sector. 2. "Flash Unsupport" or "Unknown Flash ID"

Locate and download a verified version of the software on the FirstChip FC1179 MpTools Page via repository sites like USBDev. FirstChip FC1178/FC1179 MpTools V1.0.5.2 (2022-06-01)

While keeping the pins shorted, plug the USB drive into the PC. Remove the tweezers 1 to 2 seconds after insertion. Usually, pins 29 and 30 or pins 41

Click on the Settings (or Bin Settings ) button. If prompted for a password, leave it completely blank and hit Enter.

are used to identify the "Controller Part-Number: chipYC2019" and the unique Flash ID code required for repair. The Repair Ecosystem: MPTools

When the USB input is removed and the "KEY" pin is momentarily shorted to ground (or pulled low), the chip enters . It activates an internal MOSFET, inductor, and synchronous rectifier to step up the 3.0V–4.2V battery voltage to a regulated 5.1V. This can power USB peripherals until the battery undervoltage lockout (UVLO) triggers at ~2.9V.

Disclaimer: Repairing flash drives with MPTools is a last resort. Do not use these drives to store critical, irreplaceable data. If you'd like, I can:
