HT-TM02 Flash programmer

Hey man, you were guiding me through the putty configuration, i managed to connect and tftp but i think i mesed up the wrong file again, because it has stopped giving me out output on the putty , so i was thinking about flash programmer as you said, but where can i get the code to flash to it.

should probably go into Stuck with HT-TM02 can't access 192.168.1.1
