Hi I've been using CHDK on my A590, G9 and SX230 but can't get it to load on my SX280. I determined what version (102c) using STICK. I am using "sx280hs-102c_102d-1.4.0-4229-full.zip (689.29 kB - downloaded 199 times.)" and EOS card to make the SD card bootable. Using method 3 I loaded the unzipped files; CHDK, changelog, DISKBOOT, versreq and read me, ran EOSCard and locked the SD card before inserting it into my camera. There is no CHDK screen and the green display light flashes 3 times. Can anyone tell me what I'm doing wrong?
