My 700D suddenly stopped working and freezes with a "Busy ... please wait" on the LiveView or "busy" on the top panel in non-LiveView mode. Powering off the camera doesn't help. Only way is to remove the battery and re-insert it. No images saved. Happens with or without an SD card inserted.
I tried to change the card to delete all the data on the card I tried to reinstall the firmware, but everything is exactly this problem
