Chosen Solution

How do I perform a hard reset on my Nikon D5100 DSLR so that it resorts to ‘out of the box’ mode (i.e. when I switch it on it will prompt for time zone and day/date settings)?

Get the manual from here Page 58 and 59 will show you all the menus. Good Luck

My nikon d5100 shutter is “locked” and i am not able to push button down until on manual. what happen? Couple things

  1. Are you using AF-S lenses a. If yes, do you have enough light for Autofocus/Auto Functions to work b. If not, you have to work in Manual Mode.
  2. Try another AF-S lens, see if that works. a. If not, it could be the camera or take the lens cap off LOL
