My Rebel XT was working fine up until last night. I was trying to install CHDK but after the "leave on for 30 seconds after the blue light is solidly lit" step, It won't turn on again.
I tried different CF cards, removing the lens, removing the backup battery, letting sit without battery overnight.
When I try to turn it on, the CF light blinks once and there is no other response.
Any ideas? Can I somehow re-load the original Canon firmware?
