Flash Help - Dell AIO 964 Serious!!

Okay, im new to this forum so please forgive me if I do something wrong.

 

So my serious issue involves the Dell All-In-One 964. It was working fine 2 days ago, but it wouldnt let me scan things, so I thought a firmwire flash would solve the problem. Problem is, I downloaded 946 instead of 964... and now, the printer, when you plug it in, it goes "beep beep beep beep beep beep" and then stops, then a few seconds later it does the same thing. The power button stays green, it seems to be unresponsive to any buttons pressed, and also, it doesnt seem to be noticed by the computer, so reflashing it doesnt seem to work. Maybe you guys can help me out and lead me in the right direction towards a way to fix it. Please tell me there is a way to fix it! I cant afford to get a new printer, and I really need it for school... so please help me out here.

 

Thanks Guys.
