If successful: In MPtool, the device list will refresh and show a device with "Ready" status but 0MB capacity. If you see "Timeout" or nothing, repeat. Adjust timing—some FC1178BC need the short held for exactly 1.5 seconds after plugging.
If you want to keep using the drive after the firmware update, try this $5 mod: firstchip fc1178bc firmware hot
This alone drops temps by 10-12°C.
The FirstChip FC1178BC firmware hot technique is a controversial, last-ditch repair method that exploits the controller’s boot sequence vulnerability. It is not for the faint of heart. You will burn through a few dead drives before mastering the timing of the LED-to-ground short.
But for the tens of thousands of budget USB drives that die prematurely due to firmware cold boot failure, this method offers a Lazarus moment. When the regular MPTool shows "Download ISP Fail" or "No Device," remember: hot short, pray, release, flash. If successful: In MPtool, the device list will
Final warning: Do not attempt this on drives with personal data unless you have a binary backup of the original NAND (using a programmer). The hot method erases the firmware area — but it also voids any chance of professional recovery later.
If you succeed, your dead FC1178BC will live again. If you fail, at least you’ve learned why budget controllers cost $0.50 each.

You cannot do this with software alone. Gather these items:
Warning: If you do not have a matching ISP_Code.bin and ISP_Data.bin for your specific NAND (Toshiba, SanDisk, Intel), do not proceed. Using wrong firmware will corrupt the NAND's bad block table permanently.
Once you revive your drive using the hot method, do not trust it with important data. The FC1178BC is fundamentally unstable due to:
