Further to my post on 5 March. I must have messed up good style.
Having bobbed about from pillar to post collecting info to load up one of my 720is's (No ps.fir required, seek DRYOS info here, allbests build here etc) I finally got it up and running. I was flicking through the scripts and must have switched "Autostart" on the camera then it shut down, now despite reformatting the SD card and downloading it all again 3 times I'm still stuck with a sick camera. "***Autostart*** still appears in the bottom left corner of the screen when powered up in review mode for about 8 seconds then powers off the camera, Batteries are good, camera appears to function normally without the downloads, I've pressed all the buttons in different permutations (there's no ALT button on the 720is) where have I gone wrong and how do I get out of this mess?
All serious suggestions gratefully received.
