Rollback SSD to earlier Firmware?

Hi all. I have an Intel X25-M 160GB SSD. I recently updated the SSD using the Intel Solid-State Drive Toolbox v3.1.2 and I am having serious problems with my SSD using this new firmware.

Where can I go to obtain earlier versions of firmware for my X25-M 160GB SSD at? I'd like to rollback the firmware on my SSD to an earlier version. Is this possible?

Thanks!
