Temporarily disable real-time protection or add an exception for the tool folder.
To resolve this, you will need the specialized (Mass Production Tools). 1. Identify Your Chip
Do not unplug the drive during the flash process. firstchip fc1178bc firmware hot
Vendors flash modified firmware onto a 16GB or 32GB chip to make Windows misreport it as 128GB, 256GB, or higher. When files cross the real capacity limit, the firmware crashes.
| Error | Cause | Hot-Fix | |-------|-------|---------| | MPtool shows "Device Not Support" | Wrong firmware version | Find exact FW from a working drive of same batch | | Drive disappears during flash | Power dropout during hot plug | Use powered USB hub with 5V/2A | | "Pretest Failed" | Bad NAND blocks | Lower ECC threshold in settings (from 8 to 4 bits) | | Drive flashes but reverts after eject | ISP checksum mismatch | Re-do hot method, but check "Keep Original Bad Block Map" | Temporarily disable real-time protection or add an exception
If you have cracked open your dead flash drive and discovered a controller chip inside, you are in luck. These controllers are highly resilient, and you can almost always revive them using the correct FirstChip MpTools software and firmware.
: You can often "repair" these drives using specialized MpTools (Mass Production Tools), though this usually reverts the drive to its true (and much smaller) actual capacity. How to "Cool Down" and Fix the Drive Identify Your Chip Do not unplug the drive
Change the Scan Level to Clear or Full to force the tool to re-identify the flash memory and overwrite the problematic firmware.
