The recovery depth depends on how broken your flash memory cells are:
Example ChipGenius Reading: Protocal Version: USB 2.00 Current Speed: High Speed USB Device ID: VID = 048D PID = 1234 Controller Vendor: FirstChip Controller Part-Number: FC1179 Flash ID code: 453C98B37672 - SanDisk - 1CE [TLC]
| Error Code | Meaning | Solution | | :--- | :--- | :--- | | | No NAND chip detected | Re-solder the USB connector; try USB 2.0 port | | 0x12 | Bad block mismatch | Check Force Erase Bad Blocks in settings | | 0x1F | Firmware download failed | Install driver again; use a different PC | | 0x29 | Capacity error (counterfeit) | Manually set capacity to 50% of declared size, then reformat | | Timeout | Slow response | Disable antivirus; run MPTools from C:\ drive | firstchip fc1178 fc1179 mptools v1052 free
Connect the corrupted USB drive directly to a motherboard USB port (preferably ) rather than an external hub. 3. Launching the Software Download and extract the FirstChip_MPTools_V1052 archive.
Click the button. If your FC1178 or FC1179 drive is properly connected, it will appear in the lower pane with: The recovery depth depends on how broken your
Before starting, remember that on the USB drive. 1. Identify Your Chip
| Parameter | Recommended Setting | Explanation | | :--- | :--- | :--- | | | "Original Scan" (factory scanning) first; if that fails, try "Low‑Level Format" | Original scan rebuilds the FTL; low‑level format is more thorough but takes much longer. | | Optimisation Mode | Branded drives: “Capacity Priority”; unbranded drives: “Stability Priority” | Capacity priority maximises usable space; stability priority locks out more marginal blocks to avoid future corruption. | | Partition Settings | Default (single public partition) unless you need a CD‑ROM or encrypted partition | Custom partitions are for advanced use cases like bootable USB‑CDROM drives. | | VID/PID | Keep default values unless you have a specific reason to change them | Modifying VID/PID can help with driver recognition but is rarely necessary. | | Fixed Capacity | Do NOT enable unless you are deliberately reducing the drive size | Enabling fixed capacity tells the tool to ignore the actual NAND size and create a drive of a specific size (useful for certain compatibility scenarios). | Click the button
