I have loaded the CHDK firmware update manually as well as using CardTricks. I have verified that the files are in SD card. However, when I select "Firmware Update" from the menu on the camera, the camera just locks up with the green power indicator light on. There is not "flashing blue light" on the Printer button. The camera becomes a brick until the batteries are pulled. A check and the firmware did not upgrade.
Any ideas what I'm doing wrong?
