Plug the device back in and see if Windows Update can fetch the correct driver. 2. Use the AlcorMP (Mass Production) Tool
Almost all repair tools for the FA00/3613 error will permanently delete all data on the device.

Here is a draft for the blog post.
If you buy a promotional USB drive, a generic SD card reader, or an unbranded flash stick from an online marketplace, there is a very high chance the "brain" inside that stick is made by Alcor. They are the industry standard for cost-effective, mass-produced flash memory controllers.
Use this to determine the exact controller chip model (e.g., AU6989, AU6998) to select the correct repair tool.
: This is not a specific model of chip but rather a status code indicating the controller's inability to recognize the attached flash memory (FID).

Seek replacements if hardware-failed
While the identifier may say "Unknown," the hardware is not. Extensive reverse-engineering by hardware enthusiasts has revealed a strong correlation between the FA00 identifier and the .
To restore the device to working order, you must overwrite the corrupt code using the correct Mass Production (MP) software. Step 1: Extract the Exact Flash ID (FID)
