If anyone is interested, I have a factory firmware dump for an iCamera2 with a functional GUI. I used flash_dumper.cgi which yielded a 132mb file called fw.bin (fw_ver=V3.0.01.29). Unfortunately it appears to be a raw image and I have yet to figure out how to flash it onto another camera. Even attempting to upload it to the same camera results in "Error: Unable to read upgrade file."
