A800 flash software

Hi there,
I tried to unlock my a800 phone by typing *2767*637#.
nothing really happened. Then i type another code generated by the software on this website. I selected samsung P400, and got 3 codes. One of them, which i typed was *2767*3855# . after typing this my phone flashed and now it just flashes 3 times when i turn it on, and then a blank screen. I read on one of the forums on this site, that it needs to be flashed. I have no idea how to do that or atleast where to get the software and datacable. Please help me regarding this.

Thank you in advance..
