I'm trying to hack my a560 via 8GB SDHC card, but I'm having a little trouble loading the firmware. I followed the instructions on how to setup another partition so that I can autoboot chdk from the 8GB card (steps include loading small software on FAT32 partition then loading firmware manually), but once I got to the loading firmware manually part, I ran into a problem. I can't find the "update firmware" button. I'm in playback mode and I looked through all three menus, not one has the loading firmware option. Help please!
