SSD Wrong Firmware

Hello Internet people...my name is Bogdan...but call me The Spectre...
Problem : I have a Adata Premier Pro SP900 64GB SSD...
I...uhm...did the wrong firmware update...and now Windows will only see it as a Generic USB device...in the Control Panel-Device Manager...that's it. Is there any software out there that will enable me to re-flash the Firmware to the right one ? Because the original Firmware Updater won't see it...please tell me there is...First one that gives me the solution will have a beer :-D
