DOWNGRADING FIRMWARE
1.
The FTS 371 SMART controller will typically only accept firmware updates that are greater than the
version currently running. The PCB will accept any version of firmware if it is running its backup
firmware version. To place the PCB in this mode, simply fail the firmware upgrade process by
removing the USB drive while the firmware upgrade is being performed.

Now follow the firmware upgrade process
ADDITIONAL NOTES
Flash Technology advises removing the USB drive once the firmware is updated. However, a failure to do this will
not result in the firmware being updated with each power cycle. The controller will recognize that the firmware file
on the USB drive matches the file that was last used to upgrade it and will not commence the firmware upgrade
process.
