you've erased micom firmware. We don't know how to flash it back. sure you can do research and maybe you get success. Ogas way allows to switch partitions by changing bytes in micom's config eeprom, but not in your case.

board is too costly in india and it not too easy to find that board. this board will cost me around 200-300$ form company. even i don't know which board using in my led. you can see all pic. of my board. and plz tell me from where i can buy this board

can we copy micom chip program
