Razer Abyssus 1800 DPI not working :(

I recently traded an old PS3 controller that wasn't being used for a Razer Abyssus 1800 DPI mouse. It was working fine for awhile, up until Razer Synapse 2.0 told me to update the mouse's firmware. I proceeded to update the firmware and saw that the program hung at "Accessing bootloader" and didn't progress at all, even after waiting an hour. I proceeded to restart my computer and now the mouse isn't working at all. It's now recognized by Windows by "Unknown USB Device". I've scoured the net in search of a fix to no avail. I was hoping you guys could help me out. Thanks in advance.

Thats Razer™ quality for you.

I lol'd

Not the kind of answer I was hoping for... If anyone has any legitimate help, please reply. Thanks.
