8GB card is formatted correctly. I downloaded and unzipped "sx130is-101f-1.1.0-2905-full_BETA.zip".
I put the following files/directory on the root of the card;
CHDK (directory)
changelog.txt
DISKBOOT.BIN
PS.FI2
readme.txt
vers.req
I start the camera in "play" mode, get into the menu, and go to firmware update, where I get the screen that says "Update firmware version? 1.0.1.0>1.1.0.0" cursor to "OK" and the camera just shuts off. I have to remove the batteries to get it back to the factory firmware.
What am I missing?
