Use this guide to replace your iPad 3G's logic board.

  1. If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass. Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered. This will keep glass shards contained and provide structural integrity when prying and lifting the display.
