The Alcor Micro controller identified as (firmware FA04 ) is frequently found in high-capacity but low-quality "fake" or unbranded USB flash drives. Based on technical community consensus from sites like USBDev.ru and FlashBoot , "FA00" is often a generic identifier for a controller like the AU6989SN-GT , which may be running unstable or modified firmware.

Symptoms

Once the drive is stabilized in Test Mode, you can attempt to re-flash the microcode using specialized mass production tools available on developer databases like the Alcor Micro USBDev Repository .

ALCOR Micro – Unknown FA00, FW FA04, Hot Condition

If you successfully run AlcorMP and the error "FA00" persists, or if the "Hot" status returns instantly, the NAND flash chip has likely suffered a physical "bad block" failure or a short circuit. At this point, the hardware is no longer reliable for data storage.

Identify the larger rectangular chip (the NAND flash), not the smaller square Alcor controller chip.

Do not leave the drive plugged in for extended periods while troubleshooting. Use rapid detection tools to evaluate the chip state:

: Hold the metal bridge steady against the pins while inserting the device into a USB 2.0 port.

The controller is stuck in an initialization cycle that consumes excessive power. Step-by-Step Fixes 1. Cool Down and Test Different Ports

Leave the process to run uninterrupted. A low-level format and flash build can take anywhere from depending on the drive's size.

For FA00 errors, choose a version released after 2016 (such as AlcorMP v16.09.30.00 or AlcorMP v17.05.02.00 ). These newer versions include updated flash support tables that recognize corrupted controller signatures.
